Occlusion is an imperial factor in success of restoration, as the design of the restoration can utilize occlusal forces constructively. The occlusal forces in implant dentistry includes the transosteal forces, bone biomechanics, basic biomechanics, differences in natural teeth and implants, muscles of mastication and occlusal forces and bone resorption. In addition systematic individual treatment plans and precise surgical prosthodontic procedures based on biomechanical principles are pre requisite for optimal implant occlusion.
