Theoretical Assessment of Cross Sections for Cantilevered Implant‐Supported Prostheses

Abstract

The space restrictions for limited intermaxillary conditions reveal that the I cross-sectional design may provide the least displacement and smallest maximum normal stress under conditions in which each framework is subjected to an identical load. Each of the framework cross sections considered, however, is a viable candidate for use. The effectiveness of any particular shape in an intraoral environment cannot be easily assessed from the simple statistical analysis. Limitations of the predictability with statistical analysis as opposed to actual mechanical testing or in vivo use was noted. Less severe space restrictions would probably improve the estimated performance of the other designs.
