Outline of Final Research Achievements |
Bone tissue exhibits metabolic activity in response to the mechanical stress to the bone, resulting in bone resorption, bone addition, or alteration of trabecular structure. Therefore, inappropriate mechanical stress on the oral tissue may be a factor regarding the resorption of peri-implant bone and/or the mandibular bone beneath the denture base. In order to maintain the healthy mandible for a long time, it is necessary to understand the occlusal force applied to the dentition and the force beneath the denture base during daily function. This study attempted to develop some sensor system for measuring the load on the oral tissues during the daily function. For this purpose, the method for fixing the sensors to the oral devices, the method for output analysis, and basic technology for making the sensor systems wearable, which were essential for developing a new device for measuring the daily functional force in human mouth.

Academic Significance and Societal Importance of the Research Achievements |
本研究で開発する技術を用いたデバイスにより,これまで不明であった日常的な機能時に発揮される歯列上咬合力等が初めて明らかになる可能性がある.歯科臨床においては,この力の詳細が不明であるが故に,補綴修復材料や補綴設計等においては,臨床・研究ともに仮想咬合力をベースに考えざるを得なかった.すなわち,本研究成果は,パラファンクションの制御や合併症予防,顎関節症治療等の歯科医療への多大な貢献のみならず,歯科補綴材料開発や補綴治療設計,あるいは力と骨反応に関するメカノバイオロジー研究に対してきわめて有用なデータを提供でき,これら関連研究を加速する波及効果も期待できる.
