Research Abstract

The 3-dimensional (3-D) functional loads exerted on implants are essential factors in the biomechanical control of implant-supported overdentures. Since there have been few data in vivo, parameters which could affect the loads are still unclear. As for as the results of this study, the loads exerted on the implants during function are affected three dimensionally by the number of implants supporting the overdenture.
