骨格性III級症例の矯正と外科的管理

Orthodontic and surgical management of a skeletal Class III case.

抄録

本稿では、上顎横咬合を伴う骨格性III級症例に対して、矯正歯科的アプローチと外科的アプローチを併用した症例報告を行う。術前の矯正治療では、上顎弓の拡大を伴う不正咬合の除縮を行った。15ヶ月の矯正準備の後、患者は下顎後退手術を受けた。術後3ヶ月間は矯正の安定と仕上げを行い、治療開始から24ヶ月後に最終的なデボンディングを行った。この矯正歯科と外科のコラボレーションにより、審美的にも機能的にも非常に満足のいく結果が得られた。

This article presents a case report on a skeletal Class III associated with transverse maxillary constriction treated using a combined orthodontic and surgical approach. The presurgical orthodontic phase involved decompensation for the malocclusion accompanied by upper arch expansion. After 15 months of orthodontic preparation, the patient underwent mandibular setback surgery. A period of orthodontic stabilization and finishing was undertaken during the three months post-surgery, with final debonding 24 months after the start of treatment. The esthetic and functional results were very satisfactory thanks to this collaboration between orthodontics and surgery.
