    [摘要]目的：探討传统固定及无托槽隐形矫治技术对口腔正畸牙周指数及患者美观度的影响。方法：选取2019年4月-2021年4月于笔者医院行正畸治疗的106例患者作为研究对象，依据治疗方式不同分为观察组(n=51)与对照组(n=55)。两组患者入院后均行口腔卫生宣教，并指导患者学习改良Bass刷牙法，患者治疗期间均使用相同的牙膏及牙刷，对照组患者以传统固定矫治技术治疗，观察组患者以无托槽隐形矫治技术治疗。对比两组患者正畸治疗时间、倾斜牙扶正时间及扭转牙转正时间；对比两组患者治疗前后牙龈指数(Gingival index，GI)、菌斑指数(Plaque index，PLI)、龈沟探诊深度(Sulcus probing depth，SPD)、龈沟出血指数(Sulcus bleeding index，SBI)及龈沟液内肿瘤坏死因子-α(Tumor necrosis factor-α，TNF-α)、白细胞介素-1β(Interleukin-1β，IL-1β)，评估两组患者治疗后满意度。结果：观察组正畸治疗时间、倾斜牙扶正时间、扭转牙转正时间显著短于对照组(P<0.05)。两组治疗后GI、PLI、SBI水平显著高于治疗前(P<0.05)，且观察组GI、PLI、SBI水平显著低于对照组(P<0.05)。两组治疗后龈沟液TNF-α、IL-β水平显著低于治疗前(P<0.05)，且观察组龈沟液TNF-α、IL-β水平显著低于对照组(P<0.05)。观察组治疗后美观程度评分显著高于对照组(P<0.05)。结论：相对于传统固定矫治技术，无托槽隐形矫治技术应用于正畸治疗中可缩短正畸治疗时间，且矫治器对正畸患者的牙周健康影响轻微，具有较好的美观度，患者满意度高。

    Abstract： Objective? To investigate the effects of traditional fixation and cloakless orthodontic techniques on periodontal index and aesthetic degree of orthodontic patients. Methods? A total of 106 patients who received orthodontic treatment in the author's hospital from April 2019 to April 2021 were included in the study. All patients were divided into observation group (n=51) and control group (n=55) according to different treatment methods. Patients in both groups received oral health education after admission ......
