What does “All-on-6” mean?
All-on-6 is an expression used to describe a fixed full-arch prosthesis supported by six implants in one jaw. Here it refers to that six-implant configuration, rather than a particular product or manufacturer’s procedure.
Choose implant number and positions around the final prosthesis
Planning a fixed full-arch prosthesis considers load-bearing structure, implant distribution, and jawbone conditions together. The ITI consensus advises basing implant number and positions on the final prosthetic plan. Remaining natural teeth should first be assessed for preservation; this configuration does not automatically require their removal.
Consider support and future prosthetic maintenance
Choosing implant number involves not only position and distribution but also how a problem with one or more implants could affect support for the prosthesis. Additional implants may provide more options for supporting separate prosthetic segments. However, the number six alone cannot guarantee a better outcome or long-term retention.
Fixed prostheses still need cleaning and checks
A fixed prosthesis can still develop problems such as inflammation around implants or mechanical complications. Confirm that its design permits cleaning underneath and around the implants, learn how to clean it, and attend regular reviews. Smoking and general health also affect healing and long-term care.
Frequently Asked Questions
Do six implants mean I can receive the final teeth on the same day?
Implant number alone does not decide this. Timing depends on initial stability, bone conditions, grafting needs, and the prosthetic plan. A temporary prosthesis attached on the day must also be distinguished from the final prosthesis.
Does this mean six implants for both upper and lower jaws together?
It usually means six implants supporting a full-arch prosthesis in one jaw. Treatment scope and implant numbers are planned separately for the upper and lower jaws. Confirm which jaw is included in the treatment explanation and estimate.
