All On 6 Implants

When Is All-on-6 Preferred Over All-on-4?

While All-on-4 implant treatment delivers successful results in many full edentulism cases, certain situations require more implant support. All-on-6 is particularly preferred in the following scenarios: In upper jaw treatments: The upper jawbone has a softer and more porous structure compared to the lower jaw. For this reason, placing 6 implants instead of 4 in the upper jaw aims to distribute the load over a wider area and provide more solid support for the prosthesis. In long-span prosthesis planning: In wide prostheses extending to the posterior region, 6 implants ensure balanced distribution of chewing forces. Additional implant support extends the prosthesis lifespan, particularly in patients with strong biting habits. In cases where bone density varies by region: Bone quality is not the same throughout the jaw. While some areas have stronger bone, others may be weaker. With 6 implants, maximum support is obtained from the strongest bone regions.

Difference Between All-on-6 and Individual Implants

In cases of full edentulism, placing a separate implant for each missing tooth is theoretically possible, but this approach would mean 10 to 14 implants, significantly increasing the surgical burden, cost, and healing time. The All-on-6 method achieves the same functional outcome with far less surgical intervention by mounting a full-arch fixed prosthesis on 6 strategically placed implants. On the other hand, if only one or a few teeth are missing, individual implant placement is preferred rather than All-on-6. With individual implants, each artificial tooth stands on its own root and adjacent teeth remain untouched.

Long-Term Effects of Tooth Loss

Leaving teeth missing for extended periods doesn’t just create chewing difficulties. The jawbone renews itself through the mechanical stimulation it receives from tooth roots. When a tooth is lost, this stimulation disappears and the bone gradually resorbs over time. This resorption causes changes in facial contours, inward collapse of the lips, and an aged appearance. When an implant is placed, mechanical stimulation is once again transmitted to the jawbone and bone resorption stops. For this reason, an implant evaluation is recommended as soon as possible after tooth loss. Delays not only increase bone loss but may also create the need for additional surgical procedures such as bone grafting or sinus lifting in the future.

Material Options for All-on-6 Prosthesis

The most commonly preferred material for fixed prostheses mounted on All-on-6 implants is zirconia. Full-arch zirconia prostheses offer both exceptional durability and a natural tooth appearance. Alternatively, porcelain-veneered prostheses over a metal substructure or composite superstructures may also be considered. The material selection is decided together with the patient based on their expectations, chewing habits, and budget.

Oral Preparation Before All-on-6 Treatment

Before All-on-6 treatment, all existing issues in the mouth must be resolved. Teeth that cannot be saved are extracted, active infections are brought under control, and the bone structure is evaluated with 3D tomography. If there are decayed but salvageable teeth, they are treated with fillings or root canal treatment; preserving every tooth is the best possible approach. Post-treatment care is the determining factor in the longevity of implants. Daily oral hygiene, interdental brush use, regular professional checkups, and quitting smoking directly affect success. At Doredent, patients are called for regular checkups through a post-treatment follow-up program and prosthesis condition is monitored.
