All-on-4 is a full-arch dental implant solution in which a complete set of fixed teeth — upper, lower, or both — is supported by four dental implants. The implants are positioned strategically in the jaw, often at an angle in the posterior region, to maximise the use of available bone without the need for bone grafting in many cases. A fixed bridge (the prosthesis that replaces the teeth) is attached to the four implants, providing a stable, non-removable restoration.

Who may be suitable for All-on-4?

All-on-4 is typically considered for patients who are missing all or most of their natural teeth in one or both arches, those who currently wear full removable dentures and are seeking a fixed alternative, or those whose remaining teeth are in such poor condition that full extraction and implant-supported replacement is being considered. Suitability depends on available bone volume, gum health, and general medical health — all of which are assessed by a clinician before treatment is confirmed.

How does All-on-4 compare to removable dentures?

Removable dentures sit over the gum and are retained by suction or adhesives. They can move during eating and speaking, and many patients find them uncomfortable or limiting. An All-on-4 restoration is fixed to implants and does not move. It functions more like natural teeth in terms of stability and allows patients to eat a broader range of foods with greater confidence. However, implant-supported restorations require surgical placement, a recovery period and a higher upfront cost than dentures.

How many visits to Turkey does All-on-4 treatment require?

The number of visits depends on the chosen protocol. In some cases, patients can receive a temporary fixed prosthesis on the day of surgery (immediate loading), with the permanent prosthesis placed on a return visit once the implants have integrated. In other cases, a staged approach may be recommended. Most patients should plan for at least two visits, separated by a healing period of several months, though the specific timeline will depend on the clinical protocol and your individual case.

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

Both All-on-4 and All-on-6 use implants to support a full-arch fixed restoration. The primary difference is the number of implants used: All-on-4 uses four per arch, while All-on-6 uses six. The additional implants in an All-on-6 configuration provide greater distribution of load across the arch and may be recommended where bone density, the size of the arch, or the patient's clinical situation suggests that additional support would be beneficial. A dentist will recommend the most appropriate option following assessment.

Full-Arch Restoration

All-on-4 in Turkey

All-on-4 is an implant-supported full-arch restoration that provides a fixed set of teeth using four dental implants per arch. For patients with extensive tooth loss or those seeking a permanent alternative to full dentures, it is one of the most significant restorative treatment options available.

Overview

What All-on-4 Involves

All-on-4 is a surgical and prosthetic dental procedure designed to replace an entire arch of missing teeth using four titanium implants. The name refers to the fact that a complete set of fixed teeth — typically a full-arch bridge — is supported on just four implants rather than one per tooth.

The two posterior implants are typically placed at an angle (usually around 30–45 degrees) rather than vertically. This angled placement takes advantage of denser bone further forward in the jaw, which is particularly relevant in patients who have experienced bone loss in the posterior regions. By doing so, All-on-4 is often possible without bone grafting that might otherwise be required if all implants were placed vertically.

Once the implants are placed and the prosthesis attached, the result is a fixed arch of teeth that does not need to be removed. Patients can brush and care for the restoration in a similar way to natural teeth, and the stability it provides compared to removable dentures is often the primary motivation for choosing implant-supported treatment.

Key Features of All-on-4

Fixed restoration

The prosthesis is fixed to implants and does not need to be removed for cleaning.

Four implants per arch

Strategic implant placement provides a stable foundation for the full arch.

Angled posterior implants

Angulated placement often reduces the need for bone grafting.

Immediate provisional option

In selected cases, a temporary restoration may be placed on the day of surgery.

Full arch coverage

Replaces all teeth in the upper, lower, or both arches.

Who May Be Suitable

Clinical Suitability for All-on-4

All-on-4 is a significant surgical procedure and is not appropriate for everyone. Clinical suitability is determined by a thorough assessment that includes a review of your dental and medical history, examination, and three-dimensional imaging of the jaw.

Patients most commonly considered for All-on-4 include those who are missing all teeth in one or both arches, those who wear full removable dentures and are seeking a fixed alternative, those whose remaining teeth are in poor condition and where extraction and full-arch restoration is being recommended by their dental team, and those who have been assessed as not suitable for a full individual implant solution due to the number of teeth requiring replacement.

Factors that may affect suitability include active gum disease (which would need to be treated first), certain systemic medical conditions or medications, insufficient bone volume at the implant sites, and smoking (which can affect implant integration). A thorough consultation is always required before treatment is confirmed.

Before requesting an All-on-4 quote, it is helpful to have:

→ A recent panoramic X-ray (OPG) or CBCT scan if available
→ A clear description of your current situation — how many teeth are missing, whether you wear dentures
→ Information about your general health and any medications you take
→ Photographs showing your current smile and bite

Comparing Options

All-on-4 vs Removable Dentures

Full removable dentures are the conventional solution for complete tooth loss. They are less expensive, require no surgery, and can be made relatively quickly. However, many patients find them uncomfortable, unstable, or limiting in terms of the foods they can eat and their confidence when speaking. Over time, removable dentures can also contribute to continued bone resorption in the jaw.

Implant-supported restorations such as All-on-4 provide a fixed alternative that does not move during function. The presence of implants in the jawbone stimulates the bone in a manner similar to natural tooth roots, which can help limit the degree of bone loss over time. The restoration feels and functions more like natural teeth.

The trade-off is that All-on-4 involves surgical procedures, a recovery period, and a significantly higher upfront investment. It is a long-term commitment and should be approached as such. Not every patient who currently wears dentures will be suited to implant treatment — this is something a clinician will assess.

Treatment Planning

What the Treatment Process Involves

All-on-4 treatment in Turkey typically follows a structured process. Initial consultation and assessment — including 3D imaging — establishes the treatment plan, confirms implant positions, and allows the prosthetic design to be planned. Any remaining teeth requiring extraction are removed at or before the surgical appointment.

The surgical phase involves placement of the four implants under local anaesthesia (and sedation, if requested). In appropriate cases, a temporary fixed prosthesis is loaded immediately or shortly after surgery, allowing patients to leave with a fixed set of teeth. The permanent final prosthesis — typically made from zirconia or acrylic with a titanium frame — is placed on a subsequent visit once osseointegration has been confirmed.

Recovery from implant surgery involves a period of dietary modification (softer foods initially), oral hygiene management, and regular clinical monitoring. Patients should factor adequate recovery time into their travel plans and understand that the full treatment timeline typically spans several months across two or more visits.
