Stress and displacement analysis of dental implant prosthetics by 3-D finite element method

This paper presents the use of three-dimensional finite element method for biomechanical analysis on dental implant prosthetics. The current research focuses on three patents of dental implant threads from United States Patent and Trademark Office (USPTO) and a new conceptual design model. The three-dimensional finite element analysis is performed on dental implant models, with compressive forces of 50, 100, and 150 N, and a sheer force of 20 N with the force angle of 60 (degree) with the normal line respectively. Stress and displacement analysis is conducted at four different areas, including abutment, implant, cortical bone, and cancellous bone. Findings from this research provide guidelines for new product design of dental implant prosthetics with stress distribution and displacement characteristics.
