If you are missing all or most of your teeth, full-arch implant solutions offer a permanent, stable, and natural-looking alternative to conventional dentures. The two most common protocols are All-On-4 and All-On-6 — but which is right for you? The answer depends on your bone density, bite force requirements, and budget.
Both systems anchor a complete fixed arch of teeth to just a handful of implants — dramatically reducing surgery time and cost compared to placing an individual implant for every missing tooth.
What Is All-On-4?
All-On-4 uses four strategically placed implants per arch to support a full set of fixed teeth. Two implants are placed vertically at the front, and two are angled at up to 45 degrees at the rear. This angled placement distributes load across a wider area of bone and, crucially, allows the implants to avoid areas of poor bone density — meaning many patients who would otherwise need bone grafts can proceed directly to implant placement [verify with specialist].
What Is All-On-6?
All-On-6 uses six implants per arch, adding two additional anchor points. This increases the surface area of bone engagement, improves load distribution, and can support heavier, more durable prosthetics such as full zirconia arches. Patients with stronger bite forces, parafunction (grinding), or very high cosmetic demands often benefit from the additional stability of six implants [verify with specialist].
Bone Requirements: The Key Difference
All-On-4 was specifically designed to work with reduced bone volume by using angled implants. Patients with moderate bone loss who want to avoid bone grafting are often good All-On-4 candidates. All-On-6 typically requires adequate bone volume at all six placement sites, though it provides superior load-bearing when that bone is available.
Cost Comparison
All-On-4 is generally less expensive per arch than All-On-6 due to fewer implant components, shorter surgical time, and reduced laboratory costs [verify with specialist]. However, the right choice is not always the least expensive — the better-suited system for your anatomy and lifestyle will provide better long-term value.
Which Option Is Right for You?
There is no universal answer. Your bone density, bite strength, aesthetic goals, and budget all factor into the decision. The best approach is a 3D CT scan and a one-on-one consultation with a full-arch implant specialist who can review your individual anatomy.
