摘要:
[摘要]目的：探讨生理性支抗（PASS）矫治技术与MBT直丝弓矫治技术治疗安氏Ⅱ类1分类错牙合畸形的疗效。方法：选取2017 年3月-2020年3月笔者医院收治的114例安氏Ⅱ类1分类错牙合患者为研究对象。所有患者均先行拔除全口第一双尖牙后进行 矫治，按随机数字表法分为实验组（57例）与对照组（57例），对照组采取MBT矫治，实验组采取PASS矫治。观察两组患者 上、下颌牙排齐时间、硬组织头影测量分析、软组织头影测量分析及满意度。结果：实验组上、下颌牙排齐时间均低于对照 组（P＜0.05）。治疗后，两组患者U1-NA与U1-L1较治疗前均有所改善，实验组优于对照组（P＜0.05）；治疗后，两组患者 UL-FP、TLL-FP、下唇H线距、Z角、鼻唇角及面凸角较治疗前均有所改善，实验组优于对照组（P＜0.05）。实验组患者总意度98.24%，高于对照组的77.19%，差异有统计学意义（P＜0.05）。结论：安氏Ⅱ类1分类错牙合患者采取PASS矫治技术可有 效缩短牙列排齐时间、内收上颌牙、改善面部侧貌美学、提高矫治效率及满意度。
Abstract:
Abstract: Objective To investigate the comparative analysis of the effi cacy of pass correction technique and MBT straight wire arch correction technique in patients with Class Ⅱ Division 1 malocclusion. Methods 114 patients withⅡ1 malocclusion from March 2017 to March 2020 were selected as the subjects. All patients were treated with the fi rst and second incisors, It was divided into experimental group (57 cases) and control group (57 cases), Control group with conventional straight wire arch technique(MBT),PASS.of experimental group The time of upper and lower mandibular teeth alignment, hard tissue cephalometric analysis,soft tissue cephalometric analysis and satisfaction were observed. Results The time to align the upper and lower teeth of the experimental group was lower than that of the control group (P＜0.05). After treatment, U1-NA and U1- L1 of the two groups of patients were improved compared with before treatment, and the experimental group was better than the control group (P＜0.05). After treatment, the UL-FP, TLL-FP, lower lip H line distance, Z angle,nasolabial angle and facial lobes were improved in the two groups of patients compared with those before treatment, and the experimental group was better than the control group (P＜0.05). The total satisfaction of patients in the experimental group was higher than that in the control group (98.24%vs 77.19%, P＜0.05). Conclusion The PASS correction technique for patients with Class Ⅱ Division 1 malocclusion can eff ectively shorten the time of dentition alignment, adduct the maxillary teeth, improve the aesthetics of facial profi le as well as the effi ciency and satisfaction of correction.?/html>
