Implant Occlusion Considering Natural Teeth

Abstract

In order to sustain a dental implant placed in the jawbone for a long time, it is important to maintain a balance with the stress loaded on the superstructure ; therefore, the importance of occlusion on the implant has been emphasized. The load from the occlusion is received by the implant superstructure, the stress is transmitted to the bone tissue through the abutment, and homeostasis is maintained by a biological reaction that is different from that of natural teeth. Biological studies have shown that a stress sensor network is formed by osteocytes in the tissues surrounding implants, and so the occlusal theory of “protecting implants,” which has been proposed for a long time, can be applied to the coexistence of implants and natural teeth due to the accumulation of clinical evidence in recent years. In particular, since occlusal contact of the molars places a large load on the implant body, it is necessary to inspect the implant in a functional state such as during clenching, and to pay close attention to compatibility with the body when connecting the superstructure. In addition, for a long-term stable prognosis, force and inflammation control are essential.
