内容記述タイプ Abstract
内容記述 The line of action of a force in relation to the center of resistance of a tooth is an important consideration in determining a set of force and moment acting on the tooth. If the relationship between them could be clarified experimentally, the type of tooth movement would be also estimated, and efficient tooth movements will be achieved throughthe minimum course without round-tripping of the tooth thereby. We have developed a system for real-time measurement of two target points displacements in three dimensions and determined the location of center of resistance of a maxillary central incisor subjected to orthodontic forces in human subjects. Asa result, the center of resistance was observed at a point 0.19 times the root length from the alveolar crest and found to be closer to the crown than the location determined from a theoretical consideration. It was suggested that the location of center of resistance depends not simply on the shape of the root but on anatomical morphology or the surrounding tissues such as periodontal ligament and alveolar bone.

内容記述タイプ Abstract
内容記述 歯の抵抗中心位と荷重ベクトルの関係がわかれば,歯に与えられる力とモーメントの組み合わせが決定され,歯の移動様式を推定することができる.すなわち,歯を最終的な目標位置へ最短距離で移動するために必要な力系を設定することが可能となり,効率的な歯の移動が実現される.本研究では,磁気センサを応用した変位測定システムを用いて,ヒト上顎中切歯に矯正力を負荷した時の2標点の変位を実時間で記録し,抵抗中心位を求めた.その結果,歯の抵抗中心は歯槽頂より歯根長の19%根尖側寄りの位置に観察された.これは,従来考えられていた歯根長の歯頚側1/3よりも歯冠側寄りに位置していた.荷重時の歯の抵抗中心位は歯の形態によって,単純に決定されるものではなく,それを取り巻く歯根膜や歯槽骨の解剖学的形態などの様々な要因が複合して決定されることが示唆された.
