Apical Surgery (Apicoectomy)
A surgical procedure used for root-end infections that cannot be resolved with root canal treatment or retreatment. The tip of the root is removed, and the tooth is preserved with a retrograde filling.
Evaluate the Chance to Preserve the Tooth in Root Tip-Related Problems with Apical Surgery
In some teeth, infection at the root tip, non-healing lesions, or persistent complaints may be observed despite root canal treatment. In such cases, extraction may not always be the first option. Apical surgery is one of the advanced treatment approaches used for the controlled cleaning of the problematic area at the root tip and re-evaluation of the tooth. The goal is to increase the chance of keeping the tooth in the mouth in suitable cases and to eliminate the root tip problem in a targeted manner.
The root tip area is evaluated with X-rays to determine the size of the lesion, the condition of the previous root canal treatment, and whether apical surgery is the most appropriate next step.
Under local anesthesia, the gum is opened, bone is carefully removed to reach the root tip, and a few millimeters of the infected root tip are resected.
The inflamed or cystic tissue surrounding the root tip is cleaned. The canal opening at the root tip is sealed with a special retrograde filling material.
Bone healing is monitored with follow-up X-rays over several months. If successful, the tooth continues to function and any existing crown typically does not need replacement.
What Is Apical Surgery?
Apical surgery is the surgical cleaning of problematic tissue at the tip of the tooth root and, when necessary, re-shaping of the root tip. It is generally considered for teeth that do not heal despite root canal treatment, show recurring infection, or have persistent problems around the root tip. In suitable cases, this procedure can be an important option for preserving the tooth without extraction. Böylece hem estetik görünüm hem de günlük yaşam konforu yeniden kazanılabilir.
It can be considered for non-healing lesions at the root tip despite root canal treatment, persistent infection, recurring complaints, or certain root tip problems that cannot be resolved with standard treatments.
No. Retreatment involves re-treating the tooth from inside, while apical surgery involves surgical intervention to the root tip area.
No. Suitability is determined by evaluating the tooth structure, previous treatments, root condition, and overall prognosis.
Determine the Right Approach to Preserve the Tooth with a Detailed Evaluation
The most important aspect of apical surgery is properly evaluating whether the problem truly originates from the root tip and whether the tooth is suitable for this treatment. Because in some cases retreatment may be a better option, while in others direct intervention to the apical area may be needed. For this reason, the pre-treatment examination and imaging process is of great importance.
- The lesion and healing status around the root tip are evaluated.
- The condition of the previous root canal treatment is examined.
- The root structure and surrounding anatomical areas are analyzed.
- The most appropriate approach for preserving the tooth is planned on a custom basis.
When Is Apical Surgery Necessary?
Apical surgery (apical resection) is the final link in the endodontic treatment chain. It comes into play when infection cannot be controlled with root canal treatment and root canal retreatment, or when the lesion at the root tip requires surgical intervention.
Apical surgery is specifically planned when: an abscess or cyst has formed at the root tip and is not responding to conventional treatment, the root canal anatomy is too complex for retreatment (such as a broken instrument or canal blockage), a post (intra-canal support) is present at the root tip and removal is risky, or the tooth has an expensive restoration (bridge, crown) and intervention is desired without removing it.
How Is Apical Surgery Performed?
The procedure is performed under local anesthesia. The gum in the area of the root tip is opened and bone tissue is carefully removed to access the root tip. The infected root tip is cut by a few millimeters (resection), the surrounding inflamed or cystic tissue is cleaned, and the canal opening at the root tip is sealed with a special material (retrograde filling). The gum is then closed with sutures.
The healing process generally allows return to daily life within a few days. Full bone healing may take several months and is monitored with X-ray follow-up.
After Apical Surgery
With successful apical surgery, the tooth is preserved in the mouth and continues its function. If there is an existing crown on the tooth, it generally does not need to be replaced. If there is no crown or it needs to be renewed, the tooth is protected with a zirconia crown.
If apical surgery also fails, meaning the infection recurs or the root structure cannot provide adequate support, the last option is tooth extraction. Implant treatment is planned to replace the extracted tooth.
The Priority of Preserving the Natural Tooth
At Doredent, the fundamental principle in endodontic treatment is to preserve the natural tooth to the last possible point. Treatment steps progress sequentially as root canal treatment, retreatment, and apical surgery. At each stage, the tooth’s salvageability is evaluated and the patient is informed. Extraction is planned only when all options are exhausted.
The most effective way to prevent decay from reaching the point of requiring root canal treatment is regular check-ups and early intervention. When early-stage cavities are treated with a simple filling, none of the steps described here become necessary.
Frequently Asked Questions
We have compiled the questions we receive about this treatment and answered them as openly and transparently as possible.
It can be considered for the purpose of preserving the tooth in cases of non-healing infection, lesion at the root tip, or persistent problems despite root canal treatment.
In many cases, that is the goal. However, the definitive result is evaluated based on the existing structure of the tooth and its response to treatment.
Planning is done with appropriate anesthesia with patient comfort in mind during the procedure. There may be short-term sensitivity afterward.
The decision is based on the root structure of the tooth, the existing root canal treatment, the location of the infection, and the overall treatment plan. The most appropriate approach may be different for each patient.
No. In some cases, follow-up, retreatment, or different treatment options can be considered. The necessity is clarified after examination.
In some cases, it is an important preservative option; however, it is not always considered the last resort. The treatment sequence is planned based on the condition of the tooth.
