摘　　要：目的探讨牙周组织再生术(GTR)在牙周组织缺损正畸治疗中临床疗效及对患者牙周功能的影响。方法选取2017年6月~2019年7月本院就诊的牙周炎患者120例,随机数字表法分为观察组和对照组,每组60例。所有患者进行基础治疗,对照组采用传统正畸治疗,观察组采用正畸联合GTR治疗。比较两组患者牙龈指标、X线测量参数、牙齿松动度(TM)及临床疗效。结果治疗前两组临床附着丧失(CAL)、牙周探诊深度(PD)、牙龈指数(GI)、菌斑指数(PLI)比较,差异无统计学意义(P>0.05);治疗后,两组GI、PLI、CAL、PD与治疗前比较明显降低,观察组GI、PLI、PD较对照组降低,差异有统计学意义(P<0.05);治疗后,两组CAL比较,差异无统计学意义(P>0.05)。治疗前两组ANB角(上、下槽牙座点和鼻根点形成角)、SNB角(下槽牙座点、鼻根点和前颅顶平面形成角)、SNA角(上槽牙座点、鼻根点和蝶安中心形成角)比较,差异无统计学意义(P>0.05);治疗后,两组ANB、SNB、SNA低于治疗前,且观察组低于对照组,差异有统计学意义(P<0.05)。治疗前后两组间牙齿松动度(TM)比较,差异无统计学意义(P>0.05);治疗后两组TM较治疗前明显改善,组内比较,差异有统计学意义(P<0.05)。观察组和对照组总有效率分别为96.67%、83.33%,观察组总有效率对照组升高(P<0.05)。结论与单纯正畸治疗比较,牙周炎患者采取GTR与正畸联合治疗,可促进牙龈指标改善,改善口腔环境,有助于牙周功能的恢复,临床疗效佳。Objective To investigate the clinical effect of periodontal tissue regeneration(GTR)in orthodontic treatment of periodontal tissue defect and its effect on periodontal function.Methods A total of 120 patients with periodontitis admitted to our hospital from June 2017 to July 2019 were randomly divided into observation group and control group by number table method,with 60 patients in each group.All patients received basic treatment,the control group was treated with traditional orthodontic treatment,and the observation group was treated with orthodontic combined with GTR.Gingival indexes,X-ray measurement parameters,tooth looseness(TM)and clinical efficacy were compared between the two groups.Results Before treatment,there were no significant differences in clinical attachment loss(CAL),periodontal probing depth(PD),gingival index(GI)and plaque index(PLI)between the two groups(P>0.05).After treatment,GI,PLI,CAL,PD in the two groups were significantly decreased compared with before treatment,GI,PLI,PD in the observation group were decreased compared with the control group,the difference was statistically significant(P<0.05).After treatment,there was no significant difference in CAL between the two groups(P>0.05).Before treatment,there were no significant differences in ANB Angle(formation Angle of upper and lower alveolar base and nasal root point),SNB Angle(formation Angle of lower alveolar base,nasal root point and anterior cranial top plane)and SNA Angle(formation Angle of upper alveolar base,nasal root point and Pteroan center)between the two groups(P>0.05).After treatment,ANB,SNB and SNA in 2 groups were lower than before treatment,and observation group was lower than control group,the difference was statistically significant(P<0.05).There was no significant difference in the degree of tooth looseness(TM)between the two groups before and after treatment(P>0.05).After treatment,TM in the two groups was significantly improved compared with that before treatment,and the difference between the two groups was stat
