All-on-4 vs All-on-6 in Turkey: How Dentists Choose

What do All-on-4 and All-on-6 mean?

They are treatment concepts in which a fixed full-arch dental prosthesis is supported by four or six implants in one jaw.

The visible result is not four or six individual teeth. It is a connected full-arch prosthesis supported by implants placed in planned positions. Implant angulation, available bone and the extension of the prosthesis all affect the design.

The label also does not define every material, surgical step or temporary stage. Ask whether the quote refers to the provisional bridge, the final bridge or both.

Is All-on-6 better because it uses more implants?

Not automatically. Additional implants can change support and force distribution, but benefit depends on anatomy, placement and the prosthetic plan.

A 2026 systematic review comparing All-on-4 and All-on-6 reported broadly similar outcomes and advised caution because the included studies were heterogeneous. That means the evidence does not support choosing solely from a marketing claim that one number is universally superior.

Six implants may not be feasible or useful when bone volume, sinus position, nerve location or restorative space limits placement. Four well-planned implants may be appropriate in one case, while another person may benefit from a different number or an alternative design.

Which factors should determine the design?

The design should reflect anatomy, bone, health, bite, implant distribution, the planned prosthesis and the ability to clean it.

Three-dimensional imaging is commonly important for planning full-arch implant positions. The final plan should also explain whether extractions, grafting or gum treatment are indicated and how those steps affect the schedule.

What does immediate loading or teeth in a day mean?

It usually means a provisional bridge may be attached soon after implant placement when clinical stability and other criteria are met.

Immediate loading is not suitable in every case and does not mean the implants have already completed healing. The provisional restoration may have dietary and bite restrictions while integration progresses.

Ask what conditions must be met on the day, what alternative is planned if stability is insufficient and when the final prosthesis will be made.

How do cleaning and maintenance differ from natural teeth?

A full-arch bridge needs daily cleaning around and beneath the prosthesis plus professional maintenance tailored to the design.

The team should demonstrate the cleaning tools and access points before you leave. Ongoing reviews look at tissues, plaque control, bite, screws, wear and any change in fit.

Poor plaque control, smoking, a history of periodontitis and uncontrolled diabetes are among the factors that require careful risk discussion and follow-up around implants.

What should a full-arch quote specify?

It should specify the clinical stages, implant system, provisional and final prostheses, materials, extra procedures, return visits and aftercare.

Health Talia does not publish a fixed full-arch list price. A free x-ray review starts the assessment, and the exact quote follows the individual plan. Potential savings of up to 30% should be compared using the same clinical scope and material level.

• Number and brand or system of implants.
• Provisional restoration and final restoration as separate items.
• Final prosthesis material and framework.
• Extractions, grafting or other preparatory treatment.
• Expected visits, healing checkpoints and hotel or transfer inclusions.
• Written aftercare, maintenance and guarantee conditions.
