Abstract

The aim of this study was to investigate stresses resulting from different thicknesses of grit blast (GB) and micro arc oxidized (MAO) treated layers at the interface between temporomandibular joint (TMJ) implants and bones using three-dimensional (3D) finite element models. Several studies have investigated finite element models for TMJs, but few have examined a model for TMJ implants with treated layers. The maximum stresses in the bone occurred at the position of the first screw. Data analysis indicated a greater decrease in this stress in the case of using TMJ implants with MAO treated layers, and the stresses decreased with increasing layer thicknesses. Results confirmed that the treated layers improve biomechanical properties of the TMJ implants and release abnormal stress concentration in them. The results of this study offer the potential clinical benefit of inducing superior biomechanical behavior in TMJ implants.
