目的探讨前牙区平面横向倾斜的矫治方法。方法选取16例原发性前牙区平面横向倾斜的正畸临床患者,常规固定矫治器排齐牙列,使用颌间垂直牵引、直线型弓、不对称形摇椅弓,配合使用前牙平面导板等方法整平前牙区平面。结果经正畸治疗后,14例患者平面完全平直,2例原发性伴有骨性畸形的双平面(上颌平面、下颌平面)均倾斜的患者经治疗后基本平直。结论常规固定矫治技术配合局部垂直牵引、直线型弓、不对称形摇椅弓等特殊手段可有效纠正前牙区平面横向倾斜。
Objective To investigate the correction method of lateral tilt of plane in anterior teeth. Methods Twenty-six orthodontic patients with transverse tilt of the plane of the primary anterior region were selected. The conventional orthodontic appliance was aligned with the dentition. Vertical intermaxillary traction, linear arch, asymmetric rocking chair were used. Guides and other methods flattening anterior teeth area plane. Results After orthodontic treatment, the plane of the 14 patients was completely straight. Two patients who were inclined in both planes (maxillary plane and mandibular plane) with primary osteomalacia were almost straight after treatment. Conclusion The conventional fixed orthodontic technique with local vertical traction, linear bow, asymmetric rocker bow bow and other special measures can effectively correct the anterior tooth area 横 plane lateral tilt.
