This study aimed to evaluate the stress distribution in an implant and supporting bone with different implant materials, bone qualities, and loading protocols using a three-dimensional (3D) finite element analysis. Finite element (FE) analyses were executed on two types of dental implant materials in two different bone qualities. FE models were subjected to 100 N axial and 60 degrees oblique loading to analyze stress distribution in the implant and supporting bone. The highest von Mises stress was observed in the implant with Ti alloy material and high bone quality (108.1 MPa) under a 60 degrees oblique force. In addition, the maximum von Mises stresses at 60 degrees loading angle in cortical and cancellous bones were 6-8 times and 1-2 times higher than that of axial load in both materials, respectively. The results also revealed no significant differences between the stress values in different components of model for Ti and Gold alloys. The findings of this study may have implications not only to understand the stress distribution in implant and bone but also to determine an optimum implant material for dental implantation.
