Outline of Final Research Achievements

Orthodontic implants were implanted in the jawbone of beagle dogs to apply orthodontic force. Torque values for placement and removal, mobility, and dropout rates were evaluated for these implants.　These studies revealed the high stability of orthodontic implants in the jawbone of beagle dogs.　In addition, the orthodontic safety of the screws was evaluated by measuring the concentration of elements in the blood, and a high level of safety was demonstrated. These results indicate that orthodontic implants can be placed in the upper and lower jaw to provide orthodontic force in beagle dogs as in humans.

Academic Significance and Societal Importance of the Research Achievements

成長期の骨格性上顎前突患者の治療は、定量的な評価の難しさから未だに明らかになっていないことが多い。本研究では、動物実験を用いた基礎研究を用いて、ビーグル犬顎骨に植立した歯科矯正用インプラントの安定性と安全性を明らかにした。顎整形力のみによるデータを正確に収集を行うことが可能となったことで、今後、定量的な顎整形力の評価を行うことが可能となった。
