All-on-4 vs All-on-6 Implants: The Complete Comparison 2026
All-on-4 vs. All-on-6 Implants: Which Procedure is Right for You?
When it comes to fixed dental prosthetics for edentulous jaws, two proven methods are at the forefront: All-on-4 and All-on-6. Both methods allow for complete denture reconstruction on implants, but they differ in significant ways. This detailed comparison will help you make the right decision for your individual situation.
Turkey has established itself as a leading location for both procedures. Thousands of patients from Germany, Austria, and Switzerland receive treatment in Istanbul each year and benefit from significant cost advantages while maintaining equivalent quality. But which procedure is better suited? The answer depends on your bone structure, your expectations, and your budget.
The Basic Principle: 4 vs. 6 Implants
All-on-4: The Proven Standard Procedure
In the All-on-4 procedure, a fixed bridge is anchored on four strategically placed implants per jaw. Two implants are placed vertically in the front tooth area, and two more in the back jaw area at an angle of 30 to 45 degrees. This angulation allows for a stable anchoring even with reduced bone substance, without the need for extensive bone augmentation.
The procedure was developed in the 1990s by Dr. Paulo Malo and has since been scientifically validated through numerous long-term studies. More than two million patients worldwide have already been treated with All-on-4. You can find a detailed overview in our All-on-4 Turkey Guide 2026.
All-on-6: More Implants for More Stability
All-on-6 follows the same basic principle but uses six instead of four implants per jaw. The two additional implants are typically positioned in the premolar area and provide a wider load distribution. The procedure is particularly suitable for patients with advanced bone loss or increased mechanical stress on the jaw.
Detailed Cost Comparison 2026
Costs are a decisive factor for many patients. Here you can see the current prices of both procedures in international comparison:
| Procedure / Material | Turkey | Germany | Austria | Switzerland |
|---|---|---|---|---|
| All-on-4 Acrylic (per jaw) | 4,500 – 7,000 EUR | 12,000 – 18,000 EUR | 13,000 – 20,000 EUR | 18,000 – 28,000 CHF |
| All-on-4 Zircon (per jaw) | 7,000 – 12,000 EUR | 18,000 – 30,000 EUR | 20,000 – 32,000 EUR | 25,000 – 40,000 CHF |
| All-on-6 Acrylic (per jaw) | 6,500 – 9,000 EUR | 16,000 – 24,000 EUR | 18,000 – 26,000 EUR | 22,000 – 35,000 CHF |
| All-on-6 Zircon (per jaw) | 9,000 – 15,000 EUR | 24,000 – 38,000 EUR | 26,000 – 40,000 EUR | 30,000 – 48,000 CHF |
In Turkey, the prices for both procedures are 50 to 70 percent cheaper than in Western Europe. Detailed cost information on dental implants can be found in our Implant-Cost-Guide.
Medical differences in detail
Bone substance and requirements
All-on-4 is suitable for moderate bone loss. The angled posterior implants optimally utilize the existing bone, so in many cases, no bone augmentation (sinus lift or bone grafting) is required. This shortens the treatment duration and reduces costs.
All-on-6 offers advantages in cases of advanced bone loss. The six anchoring points distribute the chewing forces more evenly, which provides a safer solution in cases of lower bone quality. However, in cases of severe bone loss, prior bone augmentation may also be necessary for All-on-6.
Stability and load capacity
Both procedures allow for immediate loading, meaning you leave the clinic on the day of the procedure with fixed provisional teeth. The differences are evident in detail:
- All-on-4: Sufficient stability for the vast majority of patients. The chewing force reaches about 80 to 90 percent of natural teeth.
- All-on-6: Higher stability due to broader load distribution. Particularly advantageous for patients with bruxism (teeth grinding) or high chewing loads. The chewing force is at 85 to 95 percent of natural teeth.
Long-term success rates
Both procedures show excellent long-term results in clinical studies:
| Criterion | All-on-4 | All-on-6 |
|---|---|---|
| Implant survival rate (10 years) | 94 – 97% | 96 – 98% |
| Bridge survival rate (10 years) | 93 – 96% | 95 – 98% |
| Bone loss per year | 0.1 – 0.3 mm | 0.1 – 0.2 mm |
| Complication rate | 5 – 8% | 3 – 6% |
The marginal advantage of All-on-6 in success rates is explained by the additional support: If one implant fails, the remaining five can still support the bridge, whereas in All-on-4, the loss of an implant is more critical.
Procedure of both treatments in Turkey
Common procedure
The basic treatment procedure is identical for both methods and typically involves two trips to Istanbul:
- Before the trip: Remote diagnosis based on X-rays, creation of the treatment plan
- First stay (5-7 days): 3D diagnostics, surgical procedure, placement of the provisional bridge
- Healing phase (3-6 months): Osseointegration of the implants at home
- Second stay (3-5 days): Placement of the definitive zirconia or acrylic bridge
Differences in the surgical procedure
All-on-4: The procedure usually lasts 1.5 to 2.5 hours per jaw. Four implants are placed, two of which are angled. The lower surgical effort leads to fewer postoperative complaints and a faster recovery.
All-on-6: The surgery duration is 2 to 3.5 hours per jaw. Six implants are positioned, which means a slightly larger surgical procedure. The swelling may be more pronounced, but the recovery time is comparable.
Who is suitable for which procedure?
All-on-4 is ideal for:
- Patients with sufficient to slightly reduced bone substance
- Budget-conscious patients looking for a cost-effective solution
- Patients who prefer a minimally invasive procedure
- Standard cases without special risk factors
- Older patients for whom a shorter procedure is advantageous
All-on-6 is ideal for:
- Patients with advanced bone loss in the molar region
- Patients with bruxism or high chewing forces
- Younger patients seeking maximum long-term stability
- Patients with a wider dental arch, where four implants would need to support a larger bridge span
- Cases where implant loss would be particularly problematic
Material choice: Acrylic or zirconia?
Regardless of whether you choose All-on-4 or All-on-6, the choice of bridge material is next:
Acrylic on titanium framework: Cheaper to purchase (surcharge of about 2,000-4,000 EUR for zirconia), easier to repair, but more susceptible to discoloration and wear. Durability: 5 to 10 years. Suitable as a long-term provisional or for patients on a tight budget.
Monolithic zirconia: Higher aesthetics with natural light translucency, extremely fracture-resistant and discoloration-resistant. Durability: 15 to 25 years. The more economically viable solution in the long run despite higher initial investment. Further details on the durability of various materials can be found in our Durability guide.

Frequently Asked Questions
Can I switch between All-on-4 and All-on-6 during the consultation?
Yes, the final decision is often made only after the 3D diagnostics on-site in Istanbul. Experienced implantologists recommend the optimal procedure based on the DVT findings. Many clinics calculate both options in the estimate, allowing you to remain flexible.
Is All-on-6 always better than All-on-4?
No, more implants do not automatically mean a better result. With sufficient bone substance, All-on-4 offers a similarly reliable solution with less surgical effort. The decision should be made individually based on clinical findings, not generally in favor of a higher number of implants.
How long do the implants last with both procedures?
The titanium implants themselves can last a lifetime with good care. The attached bridge has a lifespan of 5 to 10 years (acrylic) or 15 to 25 years (zircon) depending on the material. Regular professional cleaning every 6 months and careful home oral hygiene are crucial for longevity.
Does the health insurance cover part of the costs?
The statutory health insurance in Germany pays the fixed subsidy for dental prosthetics regardless of the treatment location. For edentulous jaws, this is between 590 to 960 euros per jaw, depending on the bonus booklet. Private insurances often reimburse a higher percentage. Have the treatment and cost plan approved before the procedure.
Can I have both jaws treated at the same time?
Yes, simultaneous treatment of both jaws is possible with both procedures and is often performed in Turkey. The procedure then takes correspondingly longer (3 to 5 hours for All-on-4, 4 to 7 hours for All-on-6). The recovery time is similar to that of treating a single jaw.
Conclusion: Make the right choice
Both All-on-4 and All-on-6 are proven, scientifically based procedures for fixed dental prosthetics. All-on-4 offers an excellent price-performance ratio and is the optimal solution for the majority of patients. All-on-6 is particularly suitable for more complex cases with greater bone loss or increased mechanical stress.
Treatment in Turkey allows savings of 50 to 70 percent compared to Western Europe for both procedures. The choice of an experienced clinic with proven expertise in both procedures is crucial. Get detailed advice and compare several offers before making your decision.
