Abstract
This study was done to evaluate the thickness and shape of metal frameworks affectingthe adhesive strength of adhesion bridges under shearing loads.
Experimental and numerical models for the pseudo-three dimensional finite element methodwere examined.
The following results were obtained;
1. Adhesive strength of metal frameworks under shearing loads was nearly equal when thethickness was 0.55 mm or more.
2. Proximal extention of the metal framework was the most resistant shape under shearingloads.
3. Dimples of pontic side made in the abutment surface could help increasing the resistanceunder shearing loads.
4. The results of the experiments and the analysis of the pseudo-three dimensional finiteelement method were approximately equal.
5. The adhesive strength under shearing loads was considerably lower when a loose toothwas supposed as the abutment tooth.
