For the human tooth implant, the various designs of artificial metal tooth roots have been used widely. The lower jaw ordinary moves much more than the upper jaw at the biting action, and the biting force distribution in the mandible implanted a tooth root decides if the implant works for a long period or not. Then, it is very important to implant a tooth root so that the biting force in mandible will be distributed as closely as possible to those of the natural tooth and mandible combination. The actual biting force distribution in mandible of a person can never be obtained and we employed a two-dimensional FEM model of a tooth and its underneath mandible section. This model consists of following eight parts
