Three-Dimensional Finite Element Analysis of Dental Implant Threads
This paper presents the use of Three-Dimensional Finite Element Method (3D-FEM) for biomechanical analysis on dental implant prosthetics. This research focuses on three patents of threads of dental implant systems from United States Patent and Trademark Office (USPTO) and two new conceptual design models. The three-dimensional finite element analysis is performed on dental implant models, with compressive forces of 50, 100, and 150 N, and a shear force of 20 N with the force angle of 60 degrees with the normal line respectively. The Stress and displacement analysis is conducted at four different areas (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.
