What are all on 4 dental implants?
All-on-4 dental implant treatment is an advanced rehabilitation method that provides a full arch of fixed teeth using just four implants for patients suffering from complete edentulism or who are at risk of losing their remaining teeth. This concept is designed to make the most of the existing jawbone.
The system operates on the principle of placing two implants vertically in the front of the jaw and the other two at an angle of up to 45 degrees in the rear. Placing the posterior implants at this angle increases the surface area in contact with the bone, providing strong support even where bone volume is low. Furthermore, this angle reduces the risk of damaging critical anatomical structures such as the sinus cavities in the upper jaw or the nerves in the lower jaw.

All on 4 Advantages
The key features and benefits of All-on-4 are as follows:
- Fixed teeth on the same day: Often referred to as ‘Teeth in a Day,' patients can receive fixed, natural-looking temporary teeth on the same day as their surgical procedure.
- Reduces the need for bone grafting: As it utilizes the denser, stronger bone in the front of the jaw, there is often no need for the invasive, time-consuming, and costly bone grafting procedures.
- Cost-effective and fast: Using fewer implants compared to traditional methods requiring 8–10 implants shortens the treatment time and reduces costs.
- Natural function: Prostheses fixed using this method allow patients to eat, speak, and smile with confidence just as they would with their natural teeth.
- High success rate: Clinical data shows that this method has an extremely high success rate of approximately 98.3% in the lower jaw and around 98% in the upper jaw.
All-on-4 vs Traditional Implants
| Feature | All-on-4 Treatment Concept | Traditional Implant Treatment |
|---|---|---|
| Number of Implants | Requires only 4 implants per arch to support a full set of teeth. | Typically requires 6 to 10 implants (or more) per arch for a full restoration. |
| Bone Grafting | Usually eliminates the need for bone grafting by tilting posterior implants to use available bone. | Often requires bone grafting or sinus lifts if the patient has insufficient bone volume. |
| Treatment Time | Much faster; often referred to as "Teeth in a Day". | Slower; involves a series of appointments over a period of several months. |
| Immediate Function | Allows for a fixed provisional bridge to be fitted on the same day as surgery. | Often requires a healing period of several months before prosthetic teeth can be attached. |
| Invasiveness | Less invasive due to fewer implants and fewer surgical procedures (like grafting). | More invasive as it involves more implant sites and potentially complex grafting surgeries. |
| Cost | More cost-effective and efficient due to fewer components and reduced surgery. | Generally involves higher costs due to the higher number of implants and additional procedures. |
| Implant Placement | Posterior implants are tilted (up to 45°) to maximize bone support and avoid vital structures. | Implants are typically placed vertically, which often requires more bone volume in the posterior regions. |
What is the best material for all-on-4 implants?
The best material for All-on-4 dental implants depends on whether you are talking about the implants themselves or the final prosthetic bridge and also the patient’s aesthetic, durability, and cost requirements.
Materials of the implant and abutment
Titanium is the standard and most fundamental material for the system "roots."
- Titanium roots: The implants are titanium screws put into the jawbone. Titanium is bioactive, which means that it bonds well with the bone for a strong, permanent attachment.
- Abutments: These connector pieces are usually made from titanium or zirconia. They’re screwed into the titanium root to hold the final bridge in place.
Materials for Final Bridge Restoration
- Premium (The best for aesthetics and strength): This option consists of a titanium framework with individual Nobel Procera ceramic crowns (alumina or zirconia) cemented onto it. The combination is the strongest and has “excellent aesthetics," making it the highest-tier choice for a natural look and long-term durability.
- Medium (The best for repairability): A titanium framework veneered with composite. Good aesthetics and the advantage of easy repair in the lab and chairside if it is necessary.
- Basic (The most cost-effective): This uses acrylic teeth and acrylic gingiva that is applied over a titanium frame. It is the least expensive but less durable compared to ceramic or zirconia.
Framework of buildings
The best framework is a biocompatible titanium monobloc, regardless of the material of the teeth. These frameworks are cut with CAD/CAM technology, providing a consistent precision of fit, individualized design, and optimized aesthetics.
Materials, Temporary & Final
- Temporary bridges: An all-acrylic restoration is usually placed immediately after surgery. This material is lightweight and suitable for use for the first 3-6 months of healing.
- Final bridges: After the healing period is complete, the temporary acrylic is “upgraded” to the final bridge, which ideally is made from more durable porcelain, zirconia, or high-density composite.
What are all on 4 dentures?
All-on-4 dentures are a fixed and permanent dental restoration solution that uses just four dental implants to support the entire dental arch (all the teeth in either the upper or lower jaw) in cases of complete edentulism. They were developed as a modern, fixed alternative to traditional removable dentures.
The key features of All-on-4 dentures are as follows:
Structure and operating principle
- Four-implant support: Only four titanium implants, strategically fitted to the jawbone, are used to support a full set of teeth.
- Angled placement: Two implants are placed vertically in the front region, while the other two are placed at an angle of up to 45 degrees in the back region. This angle optimizes bone support and prevents the risk of damaging critical structures such as sinuses or nerves.
- Stability: These prostheses are screwed into the implants; therefore, unlike traditional dentures, they do not move or slip in the mouth and do not need to be removed at night for cleaning.
Teeth in a Day
- Rapid placement: Patients can usually go home on the same day as the surgical procedure with a temporary acrylic bridge (temporary prosthesis) fixed to their implants.
- Recovery process: After an osseointegration period of approximately 4 to 6 months, the temporary prosthesis is removed and replaced with a much more durable permanent (final) bridge.
Differences and advantages compared to traditional dentures
- Comfort and function: All-on-4 dentures feel and function like natural teeth; they do not require denture adhesive and transmit chewing force directly to the bone.
- Prevention of bone loss: While removable dentures can accelerate bone resorption, implant-supported All-on-4 dentures stimulate the bone, preventing bone loss and preserving facial structure.
- No bone graft required: Thanks to the angled placement, they can usually be fitted without the need for invasive bone grafting procedures, even in patients with low bone volume.
Materials Used
Temporary Prosthesis:
Usually made from high-density acrylic material.
Permanent Prosthesis:
Available in three levels depending on the patient’s preference:
- Basic: Acrylic teeth on a titanium framework.
- Medium: Composite veneers on a titanium framework.
- Premium: Individually crafted ceramic or zirconium crowns on a titanium framework.
All-on-4 Dental Implant Problems and Complications
Although All-on-4 treatment has a very high success rate of around 98%. However, as with any surgical procedure, there are certain risks and potential complications to consider.
Expected temporary issues following surgery
These are generally not ‘complications’ but normal reactions during the body’s healing process:
- Swelling, redness, and discomfort: It is normal to experience swelling and mild pain in the surgical area for the first few days following the operation; this usually subsides within two days.
- Change in speech (lisping): A temporary lisp may occur for a few days as the tongue adjusts to the new teeth.
Surgical and anatomical risks
- Nerve and sinus injuries: There is a risk of damaging the major nerves in the lower jaw or the sinus cavities in the upper jaw during surgery. However, in the All-on-4 technique, this risk is minimized by placing the implants at an angle to avoid these structures.
- Insufficient bone volume: For the implants to integrate successfully, the bone must have a certain width (at least 5 mm) and height (10 mm in the upper jaw, 8 mm in the lower jaw). If the bone is below these measurements, standard treatment may fail.
Obstacles affecting the treatment process
- Inability to achieve sufficient stability (Stability Issue): For ‘same-day teeth’ to be fitted, the implant must be securely fixed within the bone at a specific torque (35 N cm). If the bone is too soft and this stability cannot be achieved, the teeth cannot be fitted immediately; a waiting period of 4–6 months is required for osseointegration.
- Bruxism: In individuals with a severe habit of clenching or grinding their teeth, this treatment method carries a risk of failure due to excessive load on the implants and is generally not recommended.
Long-term health and aesthetic issues
- Gum disease (peri-implantitis): Implant teeth do not decay, but the surrounding gums can become diseased just like natural teeth. If oral hygiene is inadequate, gum inflammation and implant loss may occur.
- Bad breath and hygiene: If food debris accumulates under the denture and is not cleaned regularly, bad breath may develop.
- Aesthetic line issue: In people with a very high ‘smile line,' the point where the teeth meet the gums may be visible when smiling. To prevent this, the bone level must be carefully adjusted during surgery.

All-on-4 dental implants—How many teeth?
The specific number of teeth involved is as follows:
- Up to 12 teeth: Both the immediate provisional (temporary) bridge and the final permanent bridge are typically designed to contain up to 12 teeth.
- Optimal load distribution: The tilting of the posterior implants allows for better distribution along the alveolar crest, which safely supports this 12-tooth prosthesis.
- Full mouth replacement: If a patient receives All-on-4 for both the upper and lower jaws, the procedure can replace a full set of teeth, which would traditionally require individual implants for 28 or more teeth.
How long do all-on-4 implants last?
All-on-4 implants are designed to provide a long-term and durable solution. Scientific studies have demonstrated that these implants achieve very high survival rates over follow-up periods of up to 10 years in the lower jaw and 5 years in the upper jaw.
Which is better, all-on-4 or all-on-6 dental implants?
Which method is better depends on the patient’s jawbone volume and density.
- All-on-4: This is a cost-effective and less invasive method, generally used for patients with limited bone volume, designed to eliminate the need for bone grafting (bone powder).
- All-on-6: As it uses more implants, it provides greater support and stability for the dental arch. Your dentist will assess your bone structure using a CBCT (computed tomography) scan and determine the most suitable option for you.
Frequently Asked Questions
What is the downside of all on four dental implants?
Some of the limitations and points to note regarding this method are as follows:
- Parafunctional habits: Patients with severe teeth clenching or grinding (bruxism) may not be suitable candidates for this treatment.
- Primary stability requirement: If the implants cannot achieve sufficient stability in the bone (at least 35 Ncm torque) during the operation, the ‘same-day teeth’ (immediate function) protocol cannot be applied, and it will be necessary to wait several months for healing.
- Aesthetic concerns: In patients with a very high smile line, the ‘transition zone’ where the prosthesis ends may be visible; surgical adjustment of the bone level may be required to conceal this.
- Temporary side effects: Swelling, redness, and mild tenderness may be observed for a few days following the operation.
Why are dental implants so affordable in Turkey?
The main reasons dental implants in Turkey are more affordable include:
- Exchange rate advantage: The high value of foreign currencies against the Turkish lira makes treatment costs very attractive and ‘cost-effective’ for patients coming from abroad. Patients can save between 60% and 75% on the total cost compared to their home countries.
- Government incentives and policies: The Turkish government implements various policies and incentives to promote medical and dental tourism. These measures enable high-quality healthcare services to be provided to international patients in a more cost-effective manner.
- Economies of scale and competition: Turkey is a global hub hosting over 500,000 international dental tourists annually. The high patient volume in the sector, coupled with the presence of over 200 specialized clinics in regions such as Antalya alone, fosters competitive pricing.
