All-on-4 uses four implants to support a full-arch fixed prosthesis, using two angled posterior implants to maximise bone contact and often avoid bone grafting. All-on-6 uses six implants for greater stability and load distribution, recommended when bone quality allows. Both provide same-day fixed teeth. Abroad: All-on-4 costs $4,000–$8,000 versus $20,000–$35,000 in the US.

| Criterion | Option A | Option B |
|---|---|---|
| Number of implants | 4 implants per arch | 6 implants per arch |
| Bone graft usually needed? | Often not — angled implants maximise available bone | Sometimes — posterior implants require adequate bone width |
| Teeth on day of surgery? | Yes — same-day fixed temporary bridge | Yes — same-day fixed temporary bridge |
| Load distribution | Good — 4-point distribution | Excellent — 6-point distribution |
| Stability | High | Very high |
| Implant failure consequence | Higher impact (1 of 4 = 25% failure) | Lower impact (1 of 6 = 16.7% failure) |
| Cost in Turkey (all-inclusive) | $4,000–$8,000 per arch | $6,000–$11,000 per arch |
| Cost in the US | $20,000–$35,000 per arch | $25,000–$45,000 per arch |
| Procedure time | 2–3 hours per arch | 3–4 hours per arch |
| 10-year survival rate | 94–96% | 96–98% |
| Outcome Metric | All-on-4 Dental Implants | All-on-6 Dental Implants |
|---|---|---|
| 1-year implant survival | 97–99% | 98–99% |
| 5-year survival | 95–97% | 97–98% |
| 10-year survival | 94–96% | 96–98% |
| Patient satisfaction at 2 years | 92–95% | 94–97% |
All-on-6 shows marginally better 10-year survival rates (96–98% vs 94–96%) due to better load distribution. However, both techniques have excellent long-term outcomes. The difference becomes more clinically significant for patients with heavy bite force (bruxism) or lower bone density, where All-on-6 provides greater redundancy.
In most cases yes. The hallmark of All-on-4 is using angled posterior implants to maximise engagement in available bone, avoiding grafts even in patients with significant resorption. At leading Turkish implant centres using the Nobel Biocare All-on-4 protocol, approximately 80–85% of patients can proceed without bone grafting.
Allow 5–7 days minimum for the full procedure: Day 1 — dental CT scan and treatment planning; Day 2 — implant surgery with immediate provisional (temporary) bridge; Days 3–4 — recovery and check-up; Days 5–6 — adjustment if needed; Day 7 — departure clearance. Final permanent prosthesis is fitted 3–6 months later (remote consultation possible, with brief return trip).
Leading Istanbul and Antalya clinics use Nobel Biocare (inventor of the All-on-4 protocol), Straumann, Bego, and Alpha-Bio implants. These are the same brands used in US and European centres. Avoid clinics using unbranded 'generic' or 'Chinese' implants — they have no manufacturer warranty.
