Context: Dental implants are subjected to a variety of loads when placed in function. The implant dimensions influence the magnitude and profile of stresses within the bone. The greater the magnitude of stress applied to a dental implant system the greater the difference in strain between the implant material and bone. An optimum stress profile is required in order to maintain a strong and healthy bone. Materials and Methods: The design efficacy of the Indigenous titanium Dental implant "INDIDENT" developed by INMAS was studied using finite element stress analysis. Abacus software has been chosen for the analysis and the models are constructed as three-dimensional Solid models. The boundary conditions for each case are same. The amount of load applied is equal for all the cases as 100 N. The study involved the modeling of mandible and the dental implant meshed together. The stress generated was calculated by Finite element method using Abacus software. The different parameters used in this study for FEA simulation were stresses developed due to variation in length and diameter variation. Results and conclusion: The results indicated that the stress concentration and distribution was not effected by the length variation of the Implants. Stress concentration was same at the neck of hole and which can be reduced after suitable chamfering of the hole. The stress distribution on the effect of diameter variation indicates that if the diameter of implant was increased the contact surface also increases and simultaneously stress pattern was reduced.
