A three-dimensional finite element analysis of the influence of varying implant crest module designs on the stress distribution to the bone.

Background: The aim of this study is the effect of stress distribution within the bone with varying implant crest module designs.

Materials And Methods: Finite element models of a straight two-piece 4 mm × 13 mm screw-shaped threaded implant with divergent, straight, and convergent implant crest module with their surrounding suprastructure embedded in mandibular second premolar area were created with ANSYS software. Different implant crest module designs incorporated in D2 types of bone under 100N axial and 100N at 20° oblique load were created to evaluate stress distribution in the crestal bone around implant crest module.
