Abstract

Introduction: In addition to successful osseointegration, the goal of the modern implant therapy is to provide an esthetic and functional restoration similar to natural dentition. To this end, lots of problems still remain, including a loose abutment which often leads to patient dissatisfaction. Herein, it is aimed to investigate the mechanical properties, contact surface design in screw type abutments. Materials & Methods: In the present study, five implant systems were evaluated through 103 finite element complex models subjected to static, dynamic, thermal, and cyclic loads to simulate stress distribution in abutments and fixtures in the lateral incisor position. Results: Between the two types of the threaded abutments, one-piece screw abutments showed higher stiffness than two-piece abutments with retain screws. Conclusions: Despite the higher resistance of one-piece abutments compared to the two-piece abutments in internal connection implant systems, due to the diverse designs of implants, the results may vary in different systems. Hence, improvements in the design of the connection between the internal fixture and the abutment, holds a significant role in the loosening resistance.
