Cross‐Sectional Design and Fatigue Durability of Cantilevered Sections of Fixed Implant‐Supported Prostheses

Abstract

Four designs for the cantilevered sections of implant-supported frameworks were evaluated for fatigue durability and were compared with the results of the theoretical analysis. As tested, fatigue durability was predictable when compared with theoretical calculations of tip deflection and normal stress. Although all four shapes have considerable merit for rigidity, in limited intermaxillary conditions, the I- and L-shaped cross-sections may optimize performance and use of space.
