The use of implants have revolutionized dental treatment modalities and provided excellent durable results. In evaluation of the long-term achievement of a dental implant, the reliability and the stability of the implant–abutment and implant–bone interfaces plays an essential role. Due to these reasons, we decided to make researches on implant stabilities on a human mandible model with the use of 6 and 10 implants. This numerical study was carried out using three-dimensional finite element method (FEM). Solid models of implants were built up in Solid Works and then transferred to a mesh model in FEM (ANSYS) to perform a stress analysis. According to analysis which was performed on the mandible and implant models we find out total deformations and equivalent stress results on human mandible with the loading which was applied on different locations and numbers of implant fixtures. With the help of these analyses, we tried to observe how to obtain the most suitable implant mandible fixtures with 6 or 10 implants. In addition, we’ll be able to make comments on choice of the type of implants and their location place.
