前牙区(牙合)平面横向倾斜的临床研究

摘要

Objective To investigate the outcome of orthodontic treatment of transverse inclined occlusal plane in anterior teeth.Methods A total 16 patients with transverse inclined occlusal plane in anterior teeth were selected.Photographic measurement of the position and the inclination of transverse inclined occlusal plane in anterior teeth in open-mouth position was performed with the interpupillary line as the reference.All patients were treated with vertical intermaxillary elastics,straight arch,asymmetric reverse-curve arch and fiat bite plate.Results The inclined occlusal plane of 14 patients became straight after orthodontic treatment.The same results were achieved in other 2 patients with skeletal malocclusion after orthodontic treatment.Conclusion Orthodontic treatment with vertical intermaxillary elastics,straight arch and asymmetric reverse-curve arch was effective in correcting inclination of occlusal plane.%目的 探讨前牙区(牙合)平面横向倾斜的矫治方法.方法 选取16例原发性前牙区(牙合)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(牙合)平面.结果 经正畸治疗后,14例患者(牙合)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(牙合)平面横向倾斜.
