口腔インプラント手術におけるドリリング時の力覚体感装置の開発と応用

抄録

In order to prevent the accidental case of giving damage to nerve system in the mandibular canal in oral implant surgery, the drilling force for mandibular trabecular bone and cortical bone was quantified as a function of drilling depth with the help of stochastic multiscale finite element method (FEM). The surgeons' feeling during drilling was realized in the newly developed force sensing apparatus. The computational method allows us to consider the microarchitecture of the trabecular bone and provides its anisotropic properties, which contributes to the analysis of different drilling forces depending on the drilling angle. The numerical results were implemented in the developed apparatus and evaluated by clinicians. Finally, the developed apparatus was successfully used in the education for dental college students.
