TI-6AL-4V ELI and alumina are important bio-inert materials used in the field of dental implants due to their unique characteristics of minimal interaction with surrounding tissue. This paper presents the typical finite element method (FEM) as an effective approach for the analysis of dental implants and dental structures. In the present work, three-dimensional modeling of a molar tooth was generated by CATIA V5 software. Analyses were carried out by commercial FEA software Ansys 14.5 to evaluate the displacement, strain, stress, fatigue life, and factor of safety in the proximal region of Ti-6Al-4V ELI and alumina molar teeth implants under a static load condition of 50, 100, 150, 200, 250, and 300 N. The results show that the displacement, strain and stresses, fatigue life, and factor of safety were within the admissible material limits for alumina. Hence, the study reveals that alumina is an alternate biomaterial suitable for dental implants.
