Three-dimensional finite element analysis of posterior fiber reinforced composite fixed partial denture: framework design for pontic.

This study investigated the effects of two types of loading conditions on mechanical behavior of the pontic of composite fixed partial denture (C-FPD) and fiber reinforced composite fixed partial denture (FRC-FPD). Two types of FE model of posterior bridge were developed. Two types of loading conditions, i.e. vertical 629 N, and lateral of 250 N, were used. In lateral load, displacement was showed a similar behaviours. However in vertical load, displacement of FRC-FPD was less than C-FPD. These results clarified the magnitude, distribution of stress and displacement generated in C-FPD and FRC-FPD of pontic caused by two different loading conditions.
