How Many Implants Are Needed for Permanent Full Arch Tooth Replacement?

When replacing a complete row of teeth with an implant-supported full arch prosthesis (commonly referred to as an implant denture), dentists typically use anywhere from two to six dental implants to anchor the restoration in place. Among numerous factors, the exact number of implants will depend on jawbone density, the particular full arch tooth replacement technique employed, and which row of teeth is being replaced—upper or lower.

Despite the fact that two to four implants (including the All-on-4® method) may be an option offered at some practices, it is critical to understand that using too few dental implants to support a full arch prosthesis can increase the risk of the entire restoration failing. This is because pressure placed on the restoration—such as when chewing—is absorbed by the implants, so the fewer implants there are to absorb this force, the more likely it is that one or more may loosen within the jawbone and/or detach from the full arch restoration.

To optimize success for full arch tooth replacement patients at our practice, our dentists utilize an implant-supported denture technique known as Hybridge®, which consists of six dental implants for upper arch restorations and five dental implants for lower arch restorations. The increased number of implants enables pressure to be more widely distributed while limiting the force absorbed by each individual implant. As a result, patients benefit from a more stable, long-term full arch restoration—in addition to the many other advantages of Hybridge® versus other fullarch implant solutions.
