摘　　要：目的:探讨不同矫治技术治疗牙周炎对患者上切牙区牙槽骨密度、高度及龈沟出血变化的影响。方法:选取2016年1月—2019年12月萍乡市人民医院口腔科行正畸治疗的中度牙周炎患者23例,按照随机数字表法分为实验组(n=12)和对照组(n=11),实验组采用无托槽隐形矫治器治疗,对照组采用常规唇侧固定矫治器治疗,比较2组治疗前、后龈沟出血指数、探诊深度、上切牙区牙槽骨骨高度和骨密度变化。采用SPSS 22.0软件包对数据进行统计学分析。结果:治疗后2组上切牙区腭侧牙槽嵴顶处(L1)骨密度降低,实验组下降率显著小于对照组(P<0.05)。治疗后对照组上切牙区解剖根尖点冠方1 mm处(L3)骨密度显著减低,但实验组无明显变化。治疗前、后2组上切牙区牙槽骨高度无显著变化(P>0.05)。实验组上切牙牙根吸收程度显著低于对照组(P<0.05)。实验组上切牙压入量显著高于对照组(P<0.05)。治疗后2组探诊深度、龈沟出血指数均降低,且实验组变化量显著大于对照组(P<0.05)。结论:采用无托槽隐形矫治器治疗牙周炎,较常规唇侧固定矫正更有利于上切牙区牙槽骨骨密度恢复,且两者对骨高度影响相同,两者均为安全有效的正畸治疗方式。PURPOSE:To explore the effects of different orthodontic techniques on the changes of alveolar bone density,height and gingival crevicular fluid(GCF)bleeding in upper incisor in patients with periodontitis.METHODS:Twentythree patients with moderate periodontitis who underwent orthodontic treatment from January 2016 to December 2019 in the Department of Stomatology of Jiangxi Pingxiang People’s Hospital were divided into experimentalexperimental group(n=12)and control group(n=11).Patients in the experimental group were treated with bracket-less invisible appliance,while patients in the control group were treated with conventional lip-side fixed appliance.Changes of gingival crevicular hemorrhage index,probing depth,alveolar bone height and bone density in the incisor area were compared between the two groups before and after treatment.Statistical analysis was performed on data using SPSS 22.0 software package.RESULTS:After treatment,the bone mineral density of the upper incisor alveolar crest(L1)of the two groups decreased,and the rate of decrease in the experimental group was significantly less than that in the control group(P<0.05).The bone density at the apical point of the anatomical root of the control group at 1 mm(L3)was also significantly reduced,but there was no significant change in the experimental group.There was no significant change in the alveolar bone height of the upper incisor area between the two groups before and after treatment(P>0.05).Root resorption of the upper incisors in the experimental group was significantly lower than that in the control group(P<0.05).After treatment,the probing depth and GCF bleeding index of the two groups decreased,and the change in the experimental group was significantly greater than that in the control group(P<0.05).CONCLUSIONS:Bracket-free invisible appliance for periodontitis is more conducive to the restoration of alveolar bone mineral density in the upper incisor than the conventional lip-side fixed appliance,and both of which have the same effect on bone h
