Evaluation of Strain at the Terminal Abutment Site of a Fixed Mandibular Implant Prosthesis During Cantilever Loading

Abstract

The results of this study indicate that an optimum biomechanical environment should exist when cantilever spans exceeding 7 mm are planned regardless of the number of supporting abutments. Strain transmitted to the crestal bone can be decreased by maximizing the number and anterior-posterior spread of supporting fixtures while minimizing the distance between the distal abutment and its adjacent abutment.
