摘要: 目的:探讨改良Twin-block矫治器联合微种植体支抗治疗安氏Ⅱ类1分类错畸形的效果。方法:回顾性分析2018年1月—2022年1月如皋市中医院收治的96例安氏Ⅱ类1分类错畸形患者资料,根据治疗方法分为试验组(52例)和对照组(44例),对照组采用改良Twin-block矫治器,试验组采用改良Twin-block矫治器联合微种植体支抗。比较2组矫治时间、咬合打开时间、排列整齐时间、上下牙槽座角(ANB)、下牙槽座角(SNB)、上牙槽座角(SNA)、上中切牙长轴与NA连线的夹角(U1-NA)、下中切牙长轴与NA连线的夹角(U1-NB)、上颌中切牙长轴与前颅底平面夹角(U1-SN)、下颌中切牙长轴与下颌平面的后上交角(L1-MP)、上颌唇突度(ULP)、下颌唇突度(LLP)、上下唇突点与颏前点切线和眼耳平面夹角(Z角)、菌斑指数(PLI)、牙龈指数(GI)和龈沟出血指数(SBI)。记录并发症及患者满意度。采用SPSS 24.0软件包对数据进行统计学分析。结果:试验组患者矫治时间、咬合打开时间及排列整齐时间显著少于对照组(P<0.05)。治疗后,2组ANB、U1-NA和U1-SN小于治疗前,试验组显著小于对照组(P<0.05);U1-NB、L1-MP大于治疗前,试验组显著大于对照组(P<0.05);SNB、SNA相比无显著差异(P>0.05)。治疗后,2组ULP、LLP低于治疗前,试验组显著低于对照组(P<0.05);Z角升高,试验组显著高于对照组(P<0.05);PLI低于治疗前,试验组显著低于对照组(P<0.05);GI、SBI相比无显著差异(P>0.05)。2组患者满意度相比无显著差异(P>0.05)。结论:改良Twin-block矫治器联合微种植体支抗治疗安氏Ⅱ类1分类错畸形,有助于缩短矫治时间,改善颌骨及面部软组织轮廓,促进牙美学效果的恢复。

Abstract: PURPOSE: To explore the effectiveness of improved Twin block appliances combined with micro-implant anchorage in correction of Class Ⅱ division 1 malocclusion. METHODS: A retrospective analysis of medical records of 96 patients with Class Ⅱ division 1 malocclusion treated at Rugao Hospital of Traditional Chinese Medicine from January 2018 to January 2022 was conducted. The patients were divided into experimental group (n=52) and control group (n=44) based on the treatment methods. The control group was treated with modified Twin-block appliance, while the experimental group was treated with modified Twin-block appliance combined with micro-implant anchorage. Comparison was made between the two groups regarding treatment duration, time to achieve bite opening, alignment time, ANB angle, SNB angle, SNA angle, U1-NA angle, U1-NB angle, U1-SN angle, L1-MP angle, upper lip protrusion(ULP), lower lip protrusion (LLP), Z angle, plaque index (PLI), gingival index (GI) and sulcus bleeding index (SBI). Complications and patient satisfaction were recorded. SPSS 24.0 software package was used for statistical analysis of the data. RESULTS: The treatment duration, time to achieve bite opening and alignment time in the experimental group were significantly shorter than those in the control group (P<0.05). After treatment, ANB, U1-NA and U1-SN of the two groups were lower than before treatment, and the experimental group was significantly lower than the control group (P<0.05). U1-NB and L1-MP were higher than those before treatment, and the experimental group was significantly higher than the control group (P<0.05). There was no significant difference between SNB and SNA (P>0.05). After treatment, ULP and LLP of the two groups were lower than before treatment, and the experimental group was significantly lower than the control group(P<0.05). Z-angle of the experimental group was significantly higher than that of the control group(P<0.05). PLI in the experimental group was significantly lower than that in the control group (P<0.05). There was no significant difference between GI and SBI (P>0.05), and there was no significant difference in satisfaction between the two groups(P>0.05). CONCLUSIONS: The modified Twin-block appliance combined with micro-implant anchorage can help to shorten the treatment time, improve the jaw and facial soft tissue contour, and promote the recovery of dental aesthetics.
