Biomechanics comprises all kinds of interactions between tissues and organs of the body and the forces acting on them. Biomechanics comprises the response of the biologic tissues to the applied loads. AIMS AND OBJECTIVES: Attempt has been made to understand the basics of biomechanics with a view on finite-element stress distribution analysis in three situations namely: 1. To compare the stress distribution in a single implant with the narrow ceramic occlusal table and wide ceramic occlusal table. 2. To compare the stress distribution in two implants supporting a three-unit bridge, one model with implants placed parallel to each other and the other with one implant placed in angular position to the other. 3. To compare the difference in the stress distribution in six implants and four implants supporting mandibular over-denture. MATERIALS AND METHODS: The three-dimensional (3-D) finite-element mesh model was modeled with the standard dimension of the implant with 11-mm long and 4-mm wide using the software package 'NISA'. RESULTS AND DISCUSSION: The design, number and placement of implants play an important role. SUMMARY AND CONCLUSION: The basic principles of biomechanics must be respected.
