| Outline of Final Research Achievements |
Drilling of jaw bone and elevation of maxillary sinus membrane during oral implant surgery include a factor related to the accident. To prevent that, it is important for surgeon to recognize the force sense correctly. Hence, a force sensible surgery simulator apparatus has been developed in which the relation between the drilling depth and force predicted by a computational method considering the bone quality of the trabecular bone influenced by its microstructure and also considering the inter-individual differences was implemented. In addition, a mechanical testing apparatus was developed for maxillary sinus membrane, and the experimentally obtained results for fresh cadavers were analyzed both theoretically and numerically, which revealed the important geometrical parameters sensitive to the force. Finally, a force sensing chart was proposed to record the above findings aiming at the technology transfer. The force sensing chart for drilling was implemented in a practical software.
