摘要： 目的: 评价低摩擦自锁托槽系统联合微种植体支抗治疗成人双颌前突的疗效。方法: 选择2020年3月—2025年3月长沙市口腔医院收治的106例双颌前突患者,采用盲法以电脑随机数列分为对照组和试验组,每组各53例。对照组采用低摩擦自锁托槽系统矫治,试验组采用低摩擦自锁托槽系统联合微种植体支抗。比较两组矫治周期、头影角度参数、头影线距参数、头影软组织指标、牙周指标、牙周微环境炎症指标及并发症发生情况。结果: 试验组拔牙间隙关闭时间及矫治时间显著短于对照组（P<0.05）。治疗后,试验组U1-L1增加差值显著高于对照组,SNA角、L1-MP角缩小差值显著高于对照组（P<0.01）;两组UL-E线、LL-E线显著缩小,试验组更小（P<0.05）。治疗后,两组颏沟倾角、鼻唇角、颏唇沟深度显著增加,试验组更大（P<0.05）;两组U1-NA和U1-APo显著降低,试验组更低（P<0.05）。治疗后,两组牙龈指数（gingival index,GI）、菌斑指数（plaque index,PLI）和龈沟出血指数（sulcus bleeding index,SBI）评分显著降低,试验组更低（P<0.05）。治疗期间,两组未发生严重并发症。结论: 低摩擦自锁托槽系统联合微种植体支抗矫治成人双颌前突,能够缩短治疗时间,提升面部美学效果。

Abstract: PURPOSE: To evaluate the effect of the low-friction self-locking bracket system combined with micro-implant anchorage in the treatment of adult bimaxillary protrusion. METHODS: A total of 106 patients with bimaxillary protrusion admitted to Changsha Stomatological Hospital from March 2020 to March 2025 were selected and divided into the control group and the experimental group by blind computer random sequence, with 53 cases in each group. The control group was treated with the low-friction self-locking bracket system, while the experimental group was treated with the low-friction self-locking bracket system combined with micro-implant anchorage. The treatment duration, cephalometric angle parameters, cephalometric linear parameters, soft tissue cephalometric parameters, periodontal indices, periodontal microenvironmental inflammatory markers and the occurrence of complications were compared between the two groups. RESULTS: The time for closing the tooth extraction gap and the orthodontic treatment time in the experimental group were significantly shorter than those in the control group (P<0.05). After treatment, the difference in the increase of U1-L1 in the experimental group was significantly higher than that in the control group, and the differences in the reduction of the SNA Angle and L1-MP Angle were significantly higher than those in the control group (P<0.01). The UL-E lines and LL-E lines in both groups were significantly reduced, and those in the experimental group were even smaller (P<0.05). After treatment, the chin groove inclination angle, nasolabial angle and chin labial groove depth in both groups increased significantly, and those in the experimental group were larger (P<0.05); the U1-NA and U1-APo levels in both groups were significantly decreased, and those in the experimental group were even lower (P<0.05). After treatment, the scores of gingival index (GI), plaque index (PLI) and sulcus bleeding index (SBI) in both groups decreased significantly, and those in the experimental group were even lower(P<0.05). During the treatment period, no serious complications occurred in either group. CONCLUSIONS: The low-friction self-locking bracket system combined with micro-implant anchorage can shorten the treatment time while improving facial aesthetics in the treatment of adult bimaxillary protrusion.
