Aim: Abutment materials effect on stress distribution of underneath structures and bone was investigated within this study.

Materials: One model was built under Ansys workbench version 16 environment. Scanning premolar with contact probe scanner generated the crown geometry. On the other hand, all the other components utilized in this study were modeled in 3D by engineering CAD software. Distributed load of 450N was applied on the model to evaluate the effect of wide range of abutment materials as; PEEK, Titanium (Ti), Zirconia (Zr), and Alumina.

Results: PEEK abutment results was extremely high in comparison to other tested materials, so PEEK is not recommended for this function. Deformation and stresses patterns did not change for the other three materials, where the values were slightly different.

Conclusion: Crown deformation highly affected by abutment material rigidity. Similarly, implant and screw receive better-distributed load by the more rigid abutment. While, bone is insensitive to abutment material.
