反复扩缩式快速扩弓矫治器配合前方牵引矫治在恒牙早期安氏III类错的临床治疗效果及安全性研究(1)
[摘要] 目的 探讨反复扩缩式快速扩弓矫治器配合前方牵引矫治在恒牙早期安氏III类错牙合中的临床效果及安全性。 方法 方便选择2014年12月—2017年1月入院治疗的恒牙早期安氏III类错患者16例，入院后对患者进行常规检查，患者均采用反复扩缩式快速扩弓矫治器配合前方牵引矫治。记录并统计患者治疗前、后SNA角、SNB角、ANB角、U1/SN角、SN/MP角、OP/FH角，记录并统计患者治疗后安全性。 结果 入组患者經反复扩缩式快速扩弓矫治器配合前方牵引矫治治疗后6个月SNA角(80.12±1.58)、U1/SN角(108.57±3.25)、SN/MP角(36.55±1.32)、OP/FH角(5.87±0.29)，均高于治疗前(t=11.295、12.491、12.105、10.925，P<0.05)；患者治疗后6个月SNB角(78.43±1.12)、ANB角(0.73±0.12)，均低于治疗前(t=10.824、15.773，P<0.05)；16例患者均顺利完成治疗，治疗后对患者进行12个月随访，患者术后恢复良好，未见并发症和复发。 结论 将反复扩缩式快速扩弓矫治器配合前方牵引矫治用于恒牙早期安氏III类错中能获得良好的治疗效果，安全性较高，值得推广应用。

[Abstract] Objective To investigate the clinical effect and safety of repeated expanding and expanding rapid appliance with frontal traction in the class III malocclusion of early permanent teeth. Methods 16 patients with Class III malocclusion of early grades of permanent teeth who were admitted to hospital from December 2014 to January 2017 were selected. The patients were routinely examined after admission. The patients were repeatedly expanded with a rapid expansion appliance. Forward traction correction. The pre- and post-treatment SNA angles， SNB angles， ANB angles， U1/SN angles， SN/MP angles， and OP/FH angles were recorded and counted. The post-treatment safety was recorded and calculated. Results The SNA angle (80.12±1.58)， U1/SN angle (108.57±3.25)， and SN/MP angle (36.55±1.32) at 6 months after treatment were repeated in the group of patients undergoing repetitive expansion and rapid expansion of the appliance. OP/FH angle (5.87±0.29)， all higher than before treatment (t=11.295， 12.491， 12.105， 10.925， P<0.05)； SNB angle (78.43±1.12)， ANB angle 6 months after treatment (0.73±0.12)， both lower than before treatment (t=10.824， 15.773， P<0.05)； 16 patients were successfully treated， and patients were followed up for 12 months after treatment. The patients recovered well and no complications and relapse occurred. Conclusion The repeated expansion and rapid expansion appliance with front traction for the treatment of Angle Class III malocclusion in the early stage of permanent teeth can obtain good therapeutic effect and safety. It is worth popularizing and applying., 百拇医药(廖珊珊)
