What Is All-on-Four?

All-on-4 is a method that places a full arch of fixed teeth on just 4 implants for patients who have lost all their teeth or whose remaining teeth need to be extracted. As the name suggests, it means "all on four." While traditional implant treatment plans a separate implant for each missing tooth, All-on-4 supports a complete 12 or 14-tooth bridge with only 4 implants.

The core concept relies on the stronger bone in the front of the jaw. In the back regions, bone loss is common, especially in patients who have had missing teeth for a long time. In the All-on-4 technique, two implants are placed vertically in the front, while two are angled at approximately 30-45 degrees toward the back. This angled placement makes the most efficient use of available bone, and most patients avoid the need for additional bone grafting.

Treatment is completed in a single appointment. If teeth need to be removed, tooth extraction and implant placement can happen the same day. You leave the clinic with teeth. This feature is the most important advantage that sets All-on-4 apart from other implant methods. The first 3-6 months are the osseointegration period, during which the implants fuse with the bone. Once fusion is complete, the temporary prosthesis is removed and you receive a permanent fixed prosthesis made of zirconia or hybrid material.

For patients with stronger jawbone who want additional long-term support, All-on-6 dental implant treatment can be considered as an alternative. Which method is right for you is determined after a detailed examination and 3D tomography. For cost information, visit our dental implant cost calculator page.

Treatment Process

Alternative Treatments

All-on-4 is considered one of today's gold standard treatment options for complete or near-complete tooth loss. It is a preferred method due to its fixed structure, shorter overall treatment time, and significant improvement in quality of life. However, All-on-4 is not the only option for every patient. In some cases, a different approach may be more suitable, and in some situations, the patient's expectations and clinical conditions may require a different treatment. Below you can find the real alternatives to All-on-4 and which situations each one is best suited for.

All-on-6 Dental Implants

All-on-6 implant treatment works on the same principle as All-on-4, but involves placing 6 implants in the jaw instead of 4. The additional support provided by more implants can be preferred especially in cases with high chewing loads and when bone conditions permit. Advantages:

Provides additional mechanical support from more implants.
Chewing forces are distributed over a wider area along the jaw.
Lower risk of system compromise if one implant is lost.
Advantageous for long-term stability in cases where bone conditions are suitable.

Limitations:

Higher cost compared to All-on-4 since more implants are required.
Surgical time is slightly longer.
Requires sufficient bone height and width; may not be applicable in some cases with advanced bone loss.

The choice between All-on-4 and All-on-6 is made on a case-by-case basis according to the patient's jaw structure, bone quality and quantity, chewing habits, and clinical evaluation. There is no standard "lower jaw All-on-4, upper jaw All-on-6" rule; each case is evaluated based on its own characteristics. At Doredent, your jaw structure is examined during the initial examination with a panoramic X-ray and if necessary, a three-dimensional CT scan, and the most suitable method for you is honestly recommended.

Classic Single Implant Treatment

If the patient has not lost all their teeth and existing healthy teeth can still be used in the mouth, classic single implant treatment may be a more suitable option. In this approach, a separate implant is placed for each missing tooth and a single crown is mounted on it. Advantages:

Healthy natural teeth are preserved and not extracted.
If the number of missing teeth is limited, it is a less invasive solution.
Each implant is independent; if one has a problem, the others are not affected.
Allows the combined use of natural teeth with fixed implants.

Limitations:

If there are many missing teeth, the total cost may be higher.
In completely edentulous patients, a separate implant is not needed for each gap; All-on-4 may be a more practical solution.
In cases with a high number of missing teeth, total treatment time increases.

Implant-Supported Removable Denture (Overdenture)

Implant-supported removable denture is a method in which a removable denture with special attachments is mounted on 2-4 implants placed in the jaw. It solves the movement problem of classic removable dentures, but the patient can still remove the denture for cleaning. It is a more economical intermediate solution compared to the fixed structure of All-on-4. Advantages:

More economical than All-on-4.
Requires fewer implants; the surgical process is shorter.
Much more comfortable than classic removable dentures; the movement problem is largely resolved.
Easy to clean since the denture is removable.

Limitations:

Not fixed; the patient can remove and replace it.
Chewing force is lower compared to All-on-4.
In designs requiring palatal coverage, the taste experience may be partially reduced.
Attachment mechanisms may need to be replaced over time.

Classic Removable Denture (False Teeth)

These are classic acrylic or metal-framework removable dentures applied without placing any implants in the jaw. It is a method that has been used for decades and is still preferred in certain cases. Advantages:

The lowest cost treatment option.
Does not require surgical intervention.
An alternative for patients with advanced systemic diseases not suitable for implant surgery.
Can also be used as a temporary solution for patients who have recently lost their teeth.

Limitations:

Can shift during speaking and eating; retention problems are common especially in the lower jaw.
Chewing force remains well below that of natural teeth.
Long-term resorption develops in the underlying gum tissue and bone.
Adaptation period can be long; the foreign body sensation in the mouth is uncomfortable.
Needs to be removed daily and a separate care routine must be followed.

Which Treatment Is Right for You?

In cases of complete or near-complete tooth loss, the right treatment choice is made by evaluating together the structure of the jaw bone, the condition of remaining teeth, the patient's general health, expectations, and lifestyle. Although All-on-4 offers an ideal solution for many patients, it may not be the most suitable approach for every case. At Doredent, your jaw structure is examined in detail during the initial examination with a panoramic X-ray, clinical evaluation, and if necessary, a three-dimensional CT scan. All suitable options are clearly explained with their advantages and limitations, and the most appropriate plan is determined together with you. Our goal is to provide the most suitable solution that will ensure the patient's long-term oral health, chewing comfort, and quality of life together.

Risks and Complications

All-on-4 dental implant treatment is one of the most reliable treatments in modern dentistry for complete tooth loss, with some of the highest success rates. Current systematic reviews show long-term success rates of All-on-4 treatments, when properly planned, ranging from 94% to 98%. However, as with any surgical procedure, there are some potential risks and side effects you should know about with All-on-4 treatment. Because All-on-4 is a more comprehensive surgery than a standard single implant, these risks warrant special attention. Below you will find the main risks and side effects that may be encountered with All-on-4 dental implant treatment.

😬 Postoperative Pain, Swelling and Bruising

Because All-on-4 surgery is more extensive than a single implant surgery, you may experience noticeable pain, swelling, and occasionally bruising in the treatment area during the first few days. This is your body's natural response to the surgical procedure and typically subsides significantly within 5 to 7 days. It is managed with the pain relievers and antibiotics your dentist prescribes, along with cold compress applications.

🦠 Risk of Infection

As with any surgical procedure, there is a risk of infection with All-on-4. However, this risk is low when sterile clinic conditions, appropriate antibiotic protocols, and your compliance with postoperative hygiene guidelines are maintained. Because multiple implants are placed at once in All-on-4, maintaining oral hygiene meticulously is especially important. When infection symptoms are noticed early, they can be successfully treated.

❌ Osseointegration Failure

Failure of the osseointegration process (the fusion of implants with jawbone) in one or more implants is a rare occurrence. Because All-on-4 relies on four implants working together, the loss of one implant can affect the entire system. In this case, a new implant is placed to replace the lost one, or the treatment plan is reevaluated.

🔥 Peri-implantitis (Inflammation Around Implants)

This is an inflammatory condition that can develop over years in the gums and bone around your implants. Because All-on-4 involves multiple implants, the risk of peri-implantitis requires slightly more careful monitoring than single implant treatments. Poor hygiene, smoking, and uncontrolled diabetes increase this risk. When detected early, it can be treated; neglected cases may lead to implant loss.

⚕️ Proximity to Anatomical Structures

When implants are placed in areas near nerves in the lower jaw or near the sinus cavity in the upper jaw, complications such as nerve sensitivity or sinus perforation may occur in rare cases. Because implants in All-on-4 are placed at specific angles, their relationship to these structures requires additional planning consideration. This risk is minimized through detailed planning with three-dimensional tomography and proper surgical technique.

👑 Temporary and Permanent Prosthesis Issues

All-on-4 treatment involves first a temporary prosthesis, then a permanent one. Temporary prostheses are more delicate than permanent ones and can break with hard foods or during chewing. With permanent prostheses, issues such as wear over time, minor cracking, or screw loosening may occur. These problems typically affect the superstructure rather than the implant itself and can be resolved with repair or replacement.

Risk-Increasing Factors

Certain conditions can increase the risk of complications with All-on-4 treatment. These factors do not mean treatment cannot be performed, but they may require additional evaluation and sometimes additional precautions.

Smoking: Smoking both reduces osseointegration success and significantly increases the long-term risk of peri-implantitis. This risk is more critical in major surgeries like All-on-4. Quitting smoking before and after treatment, or at least reducing it significantly, is strongly recommended.
Uncontrolled diabetes: In patients whose blood sugar is not well controlled, the healing process is prolonged and infection risk increases. All-on-4 can be successfully performed in patients with controlled diabetes.
Poor oral hygiene: Failure to follow postoperative care guidelines increases the risk of infection and peri-implantitis. For All-on-4 patients, a daily hygiene routine remains important for life.
Bisphosphonate therapy: Bisphosphonate medications used for osteoporosis can negatively affect healing processes in the jawbone. Patients taking these medications require additional evaluation.
History of head and neck radiotherapy: Bone healing can be more difficult in areas that have received radiotherapy. These patients require special planning and additional precautions.
Bruxism (nighttime teeth grinding): Excessive chewing forces can stress the All-on-4 prosthesis. For these patients, using a night guard may become part of the treatment plan.
Advanced bone loss: In cases with very advanced bone loss, standard All-on-4 may be insufficient; alternative approaches such as sinus lifting, bone grafting, or zygomatic implants may be considered.

How Are These Risks Managed at Doredent?

The vast majority of potential risks with All-on-4 treatment can be minimized through proper planning, appropriate patient selection, and regular follow-up. The key elements of the approach applied at Doredent are:

Detailed clinical and radiological evaluation: Before treatment, the structure of your jawbone, the location of critical anatomical structures, and bone quality are examined in detail with panoramic X-rays and three-dimensional tomography. Determining the correct implant angles in All-on-4 is critical for treatment success.
Internationally certified implant brands: All implant brands used at Doredent (Nucleoss, NTA Korea, NTA Switzerland) hold CE, FDA, and ISO certifications. The same quality standards apply in All-on-4 cases.
Planning tailored to patient profile: A personalized treatment plan is created by evaluating your general health status, systemic diseases, medications used, and lifestyle habits. When necessary, treatment is postponed or additional preparatory procedures are planned.
Phased treatment follow-up: Healing and function are monitored through regular checkup appointments after surgery, during the temporary prosthesis period, and at the permanent prosthesis stage. Long-term annual checkups enable early detection of conditions such as peri-implantitis.
Patient education and compliance: Before and after treatment, you receive detailed information about surgical care, oral hygiene, smoking, and nutrition. Patient compliance plays a role in the long-term success of All-on-4 treatment that is just as important as the dentist's technical skill.

All-on-4 dental implant treatment is a safe procedure completed with high success rates when appropriate patient selection and protocols are applied. The potential risks and their likelihood in your specific case will be evaluated in detail with you by your dentist during your initial examination.

Who Is All-on-4 Right For?

All-on-4 dental implant treatment offers a fixed, long-lasting solution for patients who have lost most or all of their teeth. It allows patients who have worn removable dentures for years or whose remaining teeth are beyond saving to regain fixed teeth. However, All-on-4 is not suitable for every patient. Proper patient selection is one of the most important factors determining the long-term success of the treatment. The patient profiles below represent the groups for whom All-on-4 treatment is most commonly recommended.

😁 Patients with Complete Tooth Loss

For patients who have lost all their teeth in the upper or lower jaw, All-on-4 provides a fixed solution that offers the closest chewing and aesthetic experience to natural teeth.

Its fixed structure provides the closest chewing comfort to natural teeth.
Eliminates the loss of quality of life caused by years of being without teeth.
Does not cover the palate, so your sense of taste is not affected.
Transition to fixed teeth across the entire jaw is possible in a single treatment process.

🦷 Patients Whose Remaining Teeth Need Extraction

For patients whose existing teeth cannot be saved due to advanced decay, advanced gum disease, or fracture, All-on-4 is the fastest way to transition to a fixed solution after tooth extraction.

Extraction and implant surgery are often planned in the same appointment.
Transition directly to a fixed solution without going through a removable denture phase.
Time spent without teeth is minimized.
Treatment is completed before bone resorption in the jaw has even started.

🪥 Patients Unhappy with Removable Dentures

For patients who have worn dentures for years but experienced problems such as movement, chewing difficulty, loss of taste, and social anxiety, All-on-4 significantly improves quality of life.

Eliminates the fear of dentures moving or falling out.
Most foods, including hard foods, can be comfortably eaten.
Prosthesis does not slip during speech, increasing self-confidence.
The restrictions dentures impose on social life come to an end.

📐 Patients Without Sufficient Bone for Individual Implants

In patients who have experienced bone resorption in the jaw due to long-term tooth loss and have insufficient bone for traditional single implant treatment, All-on-4 offers a solution with lower bone requirements thanks to implants placed at different angles.

Can be applied in cases with insufficient bone for standard single implants.
The need for additional surgical procedures such as sinus lifting is often reduced.
Placing implants at different angles allows the best use of available bone.
Can often provide a solution even in cases of advanced bone loss.

🧑‍⚕️ Older Patients Who Want Fixed Teeth

There is no upper age limit for All-on-4 treatment. As long as general health is suitable, it is successfully applied in older patients and significantly improves quality of life.

Can be applied even in patients in their 70s and 80s.
Improved nutrition quality at an older age supports overall health.
Contributes to the continuation of social life and smile confidence.
When the patient's general health is suitable for surgery, treatment can be planned comfortably.

About Immediate Loading (Same-Day Temporary Teeth)

The "same-day teeth" promise often heard in All-on-4 treatment promotions is real, but not possible for every patient. In this approach, known as immediate loading, a temporary fixed prosthesis is placed on the same day immediately after implant placement, and the patient does not leave the clinic without teeth.

Conditions required for immediate loading:

Implants must demonstrate sufficient primary stability in the bone (firmly anchored to the bone)
Jawbone density must be adequate
Patient's general health condition must be favorable
Excessive chewing forces such as bruxism must be absent or under control
Clinical and radiological evaluation must support immediate loading

At Doredent, immediate loading is not a standard practice for all patients. Whether this approach is appropriate for your case is determined by the clinical evaluation and three-dimensional tomography results from your initial examination. In cases where immediate loading is not suitable, the standard approach is applied: a healing period is allowed after surgery, and then the temporary prosthesis is placed. This is not a treatment failure but a conscious clinical decision that secures the long-term outcome.

Who Requires Additional Evaluation?

In some cases, additional evaluation, preparation, or different planning is needed before All-on-4 treatment. This does not mean the treatment cannot be performed. It often means an additional step needs to be added to the treatment or certain conditions must first be met.

Uncontrolled diabetic patients: In patients whose blood sugar is poorly controlled, the healing process is prolonged and complication risk increases. Treatment is planned after diabetes is brought under control.
Those with active gum disease: If periodontal infection is present, dental scaling, curettage, and, if necessary, advanced periodontal treatments are completed first.
Heavy smokers: Smoking negatively affects osseointegration and increases the long-term risk of peri-implantitis. Cessation of smoking before and after major surgery such as All-on-4 is strongly recommended.
Patients with very advanced bone loss: While the standard All-on-4 approach works in most bone loss cases, very advanced losses may require different approaches such as additional bone grafting, sinus lifting, or zygomatic implants.
Patients taking bisphosphonates: In patients using this group of medications for osteoporosis, healing in the jawbone may be impaired. Additional evaluation is required based on the type, dose, and duration of medication use.
Patients who have received radiotherapy to the head and neck: Bone healing in areas with a history of radiotherapy may follow a different course. Special planning and additional precautions are taken in these patients.
Uncontrolled bruxism: In patients with excessive nighttime teeth grinding habits, All-on-4 prostheses may be damaged sooner than expected. Night guard use and bruxism management are planned before treatment.
Serious systemic diseases: In patients with uncontrolled heart disease, advanced kidney failure, or those receiving immunosuppressive therapy, coordinated evaluation with a physician is required before surgery.

All these conditions are evaluated at the initial examination. At Doredent, All-on-4 treatment is only performed when clinically appropriate and when conditions that support long-term success are met. In unsuitable cases, alternative treatment options are honestly recommended to the patient and referrals are made.

After Treatment

Once All-on-4 implant treatment is complete, you begin a long journey. Even if the surgery is successful, the long-term outcome depends directly on the guidelines you follow in the weeks, months, and years ahead. Because All-on-4 is a more extensive surgery than a standard single implant procedure, the healing process requires correspondingly closer attention. Below you'll find the post-surgical period explained step by step.

First 24 Hours: The Most Critical Period After Surgery

The first 24 hours after surgery are critical for bleeding control, clot formation, and managing swelling. Key points during this period:

Do not eat until the anesthesia wears off. Because your lips, inner cheeks, and tongue are numb, there is a high risk of accidentally biting these tissues. The anesthetic effect wears off in 2–3 hours. During this time, drinking water is safe.
Bite down on the gauze pads provided. Gauze placed at the surgical sites should be firmly bitten for 30–45 minutes to support clot formation. Do not use cotton, tissue, or napkins instead of gauze.
Do not spit or rinse vigorously for the first 24 hours. The pressure from spitting and vigorous rinsing can dislodge the clots at the implant sites.
Do not drink through a straw. The suction created when using a straw can disrupt clot formation.
Do not smoke. Smoking significantly reduces osseointegration success and increases infection risk. You should stay completely away from smoking for at least the first week after All-on-4; ideally you should not smoke at all during the healing period. The same rule applies to e-cigarettes and hookah.
Do not consume alcohol. Alcohol interferes with clot formation, may interact with medications, and slows healing.
Apply cold compresses to reduce swelling. Applying a cold compress to your cheek in 15-minute intervals during the first 24 hours noticeably reduces swelling.
Keep your head elevated. Sleeping with two pillows stacked to keep your head elevated reduces swelling.
Take the medications your dentist prescribed regularly. If you were prescribed antibiotics and pain relievers, take them in the recommended dose and duration. Antibiotics play a critical role in preventing infection.
Do not touch the extraction or surgical sites with your fingers or tongue. These actions can disrupt the clot and increase the risk of infection.

First Week: Living and Eating With the Temporary Prosthesis

During the first week, post-surgical healing progresses rapidly. Swelling and sensitivity decrease noticeably within 5–7 days. What to watch for during this period:

Soft-food diet: Throughout the first week, choose soft and lukewarm foods. Soups (not too hot), mashed foods, yogurt, eggs, soft pasta, bananas, and similar no-chew options are ideal. Avoid hard, hot, spicy, and acidic foods.
Be careful with the temporary prosthesis: If immediate loading was applied, a temporary fixed prosthesis may have been placed on the first day. Temporary prostheses are much more delicate than permanent ones. Absolutely avoid hard foods, nuts, and sticky foods. With the temporary prosthesis you essentially have "fixed teeth that can only eat soft foods"—full chewing capacity comes with the permanent prosthesis.
Light saltwater rinses: Starting the second day, you can do gentle rinses with lukewarm salt water. This should not be vigorous—just gently swish the water around your mouth. This helps keep the area clean.
Maintain oral hygiene: Clean areas near the surgical site very gently with a soft brush. Follow the special oral-hygiene protocols your dentist recommends.
Avoid strenuous exercise: Staying away from heavy sports and exhausting activities that raise blood pressure for the first 1–2 weeks reduces the risk of bleeding and swelling.
Suture check: Sutures are usually removed within 7–14 days. In some cases, self-dissolving sutures are used.
Watch for abnormal signs: If you experience progressively worsening pain, uncontrollable bleeding, high fever, pronounced and growing swelling, or purulent discharge, contact the clinic without delay.

First 3–6 Months: The Osseointegration Process

Osseointegration—the process by which implants fuse with the jawbone—is the most critical phase determining the long-term success of All-on-4 treatment. This process typically takes 3–6 months and occurs slightly faster in the lower jaw than the upper. During this period you will use a temporary prosthesis and will have largely returned to your daily life, but some rules still apply:

Careful use of the temporary prosthesis: The temporary prosthesis provides a comfortable transition but is not as durable as the permanent one. Stay away from hard foods, bones, and hard-shelled nuts. Because this period is called "temporary," these restrictions are temporary—they will be relaxed with the permanent prosthesis.
Chewing habits: Chewing should be balanced on both sides. Putting load on only one area can affect implant stability.
Smoking: It is strongly recommended not to smoke during the osseointegration process. Smoking is one of the most important factors that negatively affect this process.
Regular oral hygiene: Meticulous cleaning around the temporary prosthesis reduces infection risk. Use the special hygiene tools (interdental brushes, water flossers, etc.) your dentist recommends regularly.
Follow-up appointments: Several follow-up appointments are usually scheduled during this period. The condition of the implants, the fit of the temporary prosthesis, and soft-tissue healing are regularly evaluated.
General health monitoring: In patients with systemic conditions such as diabetes, controlling these conditions is important for osseointegration success.

Placement of the Permanent Prosthesis

Once osseointegration is successfully complete, the temporary prosthesis is removed and the permanent prosthesis is mounted. The permanent prosthesis is designed for long-term use with much more durable materials and a design customized specifically for you.

Impression and fitting phase: Detailed impressions are taken before fabrication of the permanent prosthesis, and color and form are determined with you. This process may span several appointments.
Material selection: Permanent All-on-4 prostheses typically feature a metal framework covered with zirconia or high-quality acrylic. Which material is right for you is determined based on clinical conditions and your preferences.
Initial adjustment period: After the permanent prosthesis is placed, you begin a few days of adjustment. Chewing, speech, and the feel in your mouth normalize within a few days.
Full chewing capacity: With the permanent prosthesis you now have chewing capacity close to that of natural teeth. Most foods, including hard ones, can be eaten comfortably—but you should still avoid habits that require excessive force, such as cracking bones or chewing ice.

Long-Term Maintenance and Follow-Up

The long-term success of All-on-4 treatment does not end when treatment is complete. A lifelong care routine ensures that your implants and prosthesis serve you trouble-free for many years. Key points to be careful about:

Daily hygiene: Brushing twice daily with a soft toothbrush, interdental brushes, and preferably a water flosser (irrigator) are critical for cleaning around All-on-4 prostheses. Using classic dental floss can be difficult—special super-floss products have been designed for this.
Special hygiene tools: Use the special cleaning tools your dentist recommends regularly. A standard dental-care routine may not be sufficient for All-on-4.
Smoking and alcohol: Smoking is the most important risk factor for peri-implantitis. If possible, quit completely; at the very least, reduce significantly.
Bruxism management: If you have a nighttime teeth-grinding habit, use the night guard your dentist recommends regularly. Bruxism is one of the most important mechanical risk factors for All-on-4 prostheses.
General health: Keeping diabetes, heart disease, and other systemic conditions under control directly contributes to the longevity of implants.
Nutrition: A balanced diet and adequate calcium and vitamin D intake support bone health.

Follow-Up Schedule

Regular clinical follow-ups for All-on-4 patients are a bit more frequent than standard patient follow-up. Small problems detected early can be resolved with small interventions, while neglected problems can even lead to implant loss.

During the first year: In the first year after surgery, 3–4 follow-up appointments are scheduled. During this period, the condition of the implants, the fit of the prosthesis, and gum health are closely monitored.
In subsequent years: Standard follow-up every 6 months is applied. At these appointments, the peri-implant area, prosthesis condition, occlusion, and overall oral health are evaluated.
Professional cleaning: Professional cleaning in All-on-4 patients requires a special technique. Standard scaling instruments can scratch implant surfaces, so special ultrasonic tips or plastic instruments are used.
Annual radiographic follow-up: Once a year, a panoramic X-ray is used to evaluate the condition of the implants within the bone. This allows early detection of peri-implantitis or bone loss.

All-on-4 treatment, when combined with proper patient selection, successful surgery, and patient compliance, is a solution that can serve you trouble-free for many years. In the long-term success of treatment, your continuous follow-up and daily care routine are at least as important as the surgery itself.

Frequently Asked Questions

Are All-on-4 dental implants permanent?

All-on-4 dental implant treatment is a long-lasting solution when properly planned and maintained. The titanium implants placed into the jawbone integrate with the bone through a successful osseointegration process and can function for many years. Current scientific literature shows long-term success rates for properly performed All-on-4 treatments between 94-98%. However, it's important to distinguish between two concepts: the implants and the prosthesis (superstructure). The implants remain permanent as long as they stay anchored in the jawbone. The prosthesis may need renewal over the years due to wear, small cracks, or aesthetic reasons. The lifespan of the prosthesis depends on your oral hygiene habits, chewing forces, bruxism status, and regular clinical follow-ups. For this reason, Doredent provides no guarantees regarding All-on-4 durability. When post-treatment follow-up and daily care routines are maintained, implants can serve without issues for many years. In neglected cases, problems may appear sooner.

Is the All-on-4 procedure painful?

All-on-4 surgery is performed under local anesthesia, so you feel no pain during the procedure. Sedation can also be used if you prefer or if the surgical scope is extensive. What you feel during the procedure is only pressure and a slight pushing sensation. You can tell your dentist if you experience any discomfort during the procedure. After the procedure, once the anesthesia wears off, you may experience pain, swelling, and sometimes bruising in the surgical area. Because All-on-4 is more extensive than a standard single-implant surgery, these symptoms may be more pronounced. They are typically most intense during the first 2-3 days and decrease noticeably within 5-7 days. When you regularly use the prescribed painkillers and antibiotics, this period is easily manageable. If you experience severe, persistent, or worsening pain, uncontrolled bleeding, or high fever, you should contact the clinic. When caught early, these situations can be resolved with minor interventions.

Can teeth be placed the same day?

The immediate-loading approach, also known as "same-day teeth," is a frequently heard promise in All-on-4 treatment marketing. In this approach, a temporary fixed prosthesis is placed immediately after the implants are inserted on the same day, and you leave the clinic with teeth. However, one point needs clarification: immediate loading is not possible for every patient. For this approach to be applicable, the implants must show sufficient primary stability in the bone (firmly anchored), the jawbone density must be appropriate, your general health must be favorable, and excessive chewing forces such as bruxism must be under control. At Doredent, immediate loading is not a standard practice for all patients. Whether this approach is suitable for your case is determined after the initial examination, clinical evaluation, and 3D tomography results. In cases where immediate loading is not appropriate, the standard approach is followed: the healing period is waited after surgery, then the temporary prosthesis is placed. This is not a treatment failure but a conscious clinical decision that secures the long-term outcome.

Can All-on-4 be applied to everyone?

No. Although All-on-4 treatment offers a suitable solution for many patients, it is not the right treatment for every patient. Proper patient selection is one of the most important factors determining the long-term success of the treatment. Conditions requiring additional evaluation for All-on-4 include: uncontrolled diabetes, heavy smoking, active gum disease, severe bone loss, bisphosphonate therapy, history of head-neck radiotherapy, uncontrolled bruxism, and serious systemic diseases. These conditions do not mean treatment cannot be performed; however, they may require additional preparation, preliminary treatment, or different planning. In some cases, alternative approaches such as additional bone grafting, sinus lifting, or zygomatic implants are evaluated. The most suitable treatment for you is determined after the clinical and radiological evaluation at the initial examination. At Doredent, alternative treatment options are honestly recommended to patients for whom All-on-4 is not suitable.

How long does the healing process take?

The healing process for All-on-4 treatment is evaluated in two different stages: short-term post-surgical healing and the osseointegration process. Short-term post-surgical healing typically takes 7-14 days. During this period, you experience swelling, mild pain, and soft tissue healing. Most patients return to daily life to a large extent by the end of the first week. The osseointegration process—the integration of implants with the jawbone—is a longer and more critical stage. This process typically takes 3-6 months and is completed slightly faster in the lower jaw than the upper jaw. During this period, a temporary prosthesis is worn, and you continue your social and professional life. Once osseointegration is successfully completed, the temporary prosthesis is removed and the permanent prosthesis is mounted. Healing speed is not the same for every patient. Factors such as general health status, smoking, presence of systemic diseases, patient compliance, and post-surgical care directly affect healing processes.

Is All-on-4 more advantageous than removable dentures?

For patients who have used removable dentures for years and are not satisfied with this experience, All-on-4 treatment significantly changes quality of life. The fundamental differences between the two treatments are as follows: The most common problems with removable dentures are slipping, movement in the mouth, difficulty chewing, and loss of taste caused by palatal coverage. Many patients worry about the denture falling out in social settings, cannot eat hard foods, and experience reduced taste. Additionally, removable dentures lead to bone resorption under the denture over time, which further worsens the denture's fit over the years. In All-on-4 treatment, implants are screwed into the jawbone and the superstructure is fixed. The prosthesis does not move, most foods including hard foods can be consumed comfortably, the taste experience is not affected because there is no palatal coverage, and the load transmitted to the bone by the implants largely prevents jawbone resorption. Chewing force reaches a level very close to natural teeth. However, All-on-4 is a surgical procedure and has a higher cost than removable dentures. Which option is suitable for you is evaluated together at the initial examination based on your clinical situation, expectations, and general health conditions. To learn about the differences between traditional single dental implant treatment and All-on-4, you can review our relevant page.

What is the difference between All-on-4 and All-on-6?

All-on-4 and All-on-6 are two different approaches based on the same treatment concept. In both methods, all teeth in the jaw are replaced with a fixed prosthesis mounted on implants placed in the jaw. The only difference is the number of implants: All-on-4 uses 4 implants, All-on-6 uses 6 implants. The choice between the two methods is made based on the structure of your jawbone, bone quality and quantity, chewing habits, and general clinical evaluation. The additional mechanical support provided by more implants can be advantageous especially in cases with high chewing loads and when bone conditions permit. In the event of possible loss of one implant, the chance of the other implants supporting the system is higher. There is no standard "lower jaw All-on-4, upper jaw All-on-6" rule. Each case is evaluated according to its own characteristics. At Doredent, your jaw structure is examined with panoramic X-ray and, if necessary, 3D tomography at the initial examination, and the most suitable method for you is honestly recommended.

How do you clean after All-on-4?

The longevity of All-on-4 prostheses is directly tied to daily hygiene routines. A standard dental care routine is not sufficient for All-on-4; the area under the prosthesis and around the implants requires special attention. Recommended cleaning tools and methods include: brushing twice daily with a soft-bristled toothbrush; interdental brushes to clean areas under the prosthesis; special dental floss called "super floss" because traditional floss is difficult to use; or the most effective solution, a water flosser (irrigator). A water flosser prevents plaque buildup by rinsing hard-to-reach areas under the prosthesis and complements professional dental scaling. In addition to regular home care, professional clinical cleaning every 6 months is essential. Professional cleaning for All-on-4 patients is not done with standard tools but with special ultrasonic tips or plastic instruments that do not scratch the implant surface. These cleanings minimize the risk of peri-implantitis and support the long life of the implants.

Can a smoker have All-on-4?

Smoking is one of the factors most negatively affecting the success of All-on-4 treatment. Smoking both directly disrupts the osseointegration process and seriously increases the long-term risk of peri-implantitis (inflammation around the implant). For this reason, smoking is one of the most important issues to address before and after All-on-4 treatment. Smokers are not completely excluded from treatment, but they are honestly given this information: if smoking continues, the risk of implant loss increases significantly. Ideally, smoking should be stopped at least 1-2 weeks before treatment, and no smoking should occur for at least 2-3 weeks after surgery. For the long-term success of the treatment, smoking should be stopped completely if possible, or at least significantly reduced. The same rules apply to e-cigarettes and hookah; these products should not be considered "alternatives." At Doredent, smoking is honestly addressed at the initial examination. If you conceal the truth on this matter, it negatively affects treatment success. Treatment is not refused to smokers, but the higher risks are clearly explained and you make an informed decision.
