摘要

本病例報告為介紹利用掩飾性矯正方式，治療成年骨性三級異常咬合合併前牙錯咬與功能性位移之治療流程及機轉。病人為26歲女性，主訴臉部外觀不佳與牙齒不整齊。經臨床及影像檢查發現，病人正面觀呈寬短的臉型，側面為直臉型伴有上唇後縮，下顎齒列齒間間隙及中線偏移，呈現安格氏三級咬合關係。因病人不願意接受正顎手術，故採用掩飾性矯正治療，以不拔牙的方式配合迷你植體進行全齒列後退，合併適當的下顎骨後下旋轉，改善顏面外觀及咬合關係。

The objective of this case report was to present the treatment proceduces and mechanisms of camouflage orthodontic treatment for skeletal Class III malocclusion with anterior cross bite and functional shift. A 26-year-old female patient complained of unsatisfactory lateral profile and poor teeth alignment. Clinical and radiographic examinations revealed frontal euryprosopic facial type and straight lateral profile with retrusion of upper lip. Spacing of lower dentition with dental midline deviation, and Angle's Class III relationship were presented. Because the patient chose not to receice an orthognathic surgery, camouflage orthodontic treatment with non-extracted method was used for the correction. Dental arch distalization by mini-implant and modest backward rotation of the mandible were conducted to improve her facial esthetics and occlusion.
