Outline of Final Research Achievements

The mandibular movement recording device developed by us delivered stable output signals and had a sufficient measurement range for checking jaw movements. It was verified that the masticatory movement and the jaw pathways on the lateral excursions recorded with the newly developed device approximated those determined a commercially available high-precision mandibular movement recording device. From these results it was confirmed that the newly developed three-dimensional mandibular movement recording device is capable of recording and analyzing jaw movements to essentially the same degree as the high-precision mandibular movement recording device, and suggested that it is also clinically applicable.

Academic Significance and Societal Importance of the Research Achievements

新たに開発した2台のスポーツ用カメラを用いた3次元咀嚼運動測定装置は高精度の下顎運動記録装置と同程度に顎運動を記録・分析できることが確認でき、臨床応用できる可能性があることが示唆された。
