摘要/Abstract

摘要： 目的　探讨配合前牙区微种植体矫治成人内倾型深覆he的临床效果及矫治机理。方法　选择内倾型深覆he成人患者12例，采用前牙种植钉压低唇倾上颌前牙。测量治疗前后上中切牙在锥形束CT影像上的指标变化。结果　12例患者上中切牙唇倾度正常。中切牙切缘点至腭平面垂直距离减少（1.59±2.05）mm，唇向倾斜19.34°±7.96°。结论　在上颌前牙区使用微种植体可以同时压低和唇倾上颌前牙。

Abstract: Objective　To explore the clinical effect and mechanism of orthodontic treatment for Class II Division 2 with miniscrew. Methods　A total of 12 adult patients with retroclined maxillary incisors and deep overbite were selected. Anterior teeth were intruded by miniscrews. The changes of upper incisors in CBCT images were measured. Results　The inclination of the upper incisors returned to normal in 12 patients. The vertical distance from incisor edge to palatal plane decreased by（1.59±2.05）mm, and incisors labially inclined 19.34°±7.96°. Conclusions　In the maxillary anterior region, miniscrew can simultaneously intrude and labially incline upper incisors.

Key words: miniscrew, labial inclination, intrusion, Class II Division 2
