Analysis of Stresses Induced in Mandibular Bone as a Result of Occlusal Forces Applied on Implant Supported Overdenture with Different Teeth Inclinations (Three Dimensional FiniteElement Analysis)

Use of implant as overdenture abutments has become part of accepted clinical practice and control of occlusal forces applied on dental implant is an important factor in implant success. Aim: This study aimed to identify and compare the effect of vertical and oblique occlusal loads applied on posterior flat teeth of mandibular implant supported overdenture at different inclinationsanalysisusing flat teeth with Finite Element Analysisapplied. Material and Methods: Three models of lower implants supported overdenture with different posterior teeth inclination were drawn (first model with zero tilt, second with inward inclination and the third model with outward inclination) stress analysis using finite element analysis (FEA) was done for the three models. Result: The model with the outward inclination of the posterior teeth achievedthe least values of stresses while the model with the zero tilt inclination achieved the highest values. Conclusion: Arranging posterior teeth with outward inclination reduce the stresses in certain cases.
