Abstract

Applying appropriate stress through the teeth is considered essential for maintaining the homeostasis of the jaw. The aim of this study was to clarify the effects of pressure applied via endosseous implants on internal structures of the jaw. A mandible with dental implants for 15 years was analyzed by micro-CT to prepare a finite element model of the mandible, including implants and the surrounding internal microstructures. Based on this model, mechanical analysis was conducted by the three-dimensional finite element method. The results showed that stress distribution was seen in the trabecular bone around the implants. It became clear that pressure is transmitted to mandibular internal structures via implants, and stress is dispersed along internal trabecular alignment.
