目的探讨前方牵引双期矫治单侧完全性唇腭裂(UCLP)术后前牙反的临床效果。方法选取20例通过单侧完全性唇腭裂术后替牙期的患者,依下颌能否退至对刃分为对刃组(10例)和轻中度骨性组(10例,下颌不能退至对刃)。对刃组通过垫加舌簧方法矫治,轻中度骨性组通过面具式前方牵引矫治。结果 20例患者前牙反均解除,改善了咬关系及侧貌。结论单侧完全性唇腭裂术后前牙反的矫治方法与常规临床患者的治疗方法基本一致,通过针对性的解剖及功能该通可达到满意的治疗效果。
Objective To investigate the clinical effect of anterior traction double-stage correction of anterior commissure on unilateral complete cleft lip and palate (UCLP). Methods Twenty patients with pterygium treated by unilateral complete cleft lip and palate after dentition were divided into two groups according to whether the mandibular recumbent edge could be retreated to the blade group (10 cases) and mild to moderate skeletal group (10 cases) Retreat to the opposite edge). The blade group was treated by pad and tongue method, and the mild and moderate skeletal group was treated by mask-type front traction. Results The anterior crossbite of 20 patients were relieved, which improved the relationship and appearance of the bite. Conclusion The treatment of anterior commissure with unilateral complete cleft lip and palate is basically the same as that of the conventional clinical patients. Satisfactory treatment effect can be achieved through targeted anatomy and function.
