| Outline of Final Research Achievements |
Simultaneous measurement of bone conduction sound in which detects occlusal tooth contacts and electromyography of masticatory muscle were performed to evaluate relationship between occlusal tooth contacts and masticatory muscle activities. Bitescan (SHARP) that counts number of chewing times from vibration of the skin behind ear was also applied to confirm the validity of those measurements.
Ten healthy subjects were participated for the examination of occlusal contact pattern during lunch time with those instruments. Results of this research will be reported on the 130th commemorative scientific meeting of the Japan Prosthodontic Society.

| Academic Significance and Societal Importance of the Research Achievements |
下顎歯列の過剰な接触は歯痛、頭痛などを初めとする様々の歯科的障害の原因となることが報告されている。本研究はこの問題を解決するために、日常生活中 の上下歯列の接触を客観的に観察する装置を開発し、臨床応用を行うことを目的とする。本研究では生体内を伝播する音波である骨伝導音(Bone Conduction Sound)を利用した歯列接触モニタを開発し、上下顎歯列の接触状態を連続して記録する方法を確立することを目的とした。
