All on 4 and All on 6 are full-arch dental implant procedures designed to replace missing teeth. Both involve fixed prosthetics supported by implants, but they differ in the number of implants used and how they distribute force across the jaw.
All on 4 uses four implants per arch, positioned strategically to maximize existing bone and often avoid bone grafting. Two of the implants are typically angled. This method is often recommended for patients with some bone loss or those seeking a shorter procedure timeline.
All on 6 uses six implants per arch, offering more support and spreading bite pressure more evenly. This can increase long-term durability, particularly for patients with strong jawbone structure. The additional implants may provide better stability under stress.
Procedure steps are similar for both options. Implants are placed in one surgical session, followed by a temporary prosthetic. After healing, the final prosthetic is attached. The timeline from surgery to final teeth is typically a few months.
In terms of cost, All on 6 is generally more expensive due to the extra implants and longer procedure. Both procedures fall within the $15,000–$30,000 range per arch, depending on materials and the provider. Insurance coverage is limited. Financing is common.
Maintenance is the same for both systems: daily cleaning, periodic checkups, and monitoring for wear or implant issues. Patients must maintain good oral hygiene and avoid smoking to protect implant success.
Choosing between All on 4 and All on 6 depends on bone health, budget, and long-term expectations. Providers will assess imaging and discuss which approach fits your needs.
Both procedures restore function and aesthetics, offering a fixed solution that does not require removal. Patients report improvements in eating, speaking, and confidence following treatment.
Ask about the provider’s experience, prosthetic materials, costs, and follow-up care before deciding. Understanding the structural differences helps in choosing the most suitable option for your situation.
