正畸患者隐形矫治中采用不同附件的临床效果研究

Clinical observation of using different attachments in invisible orthodontic treatment for orthodontic patients

目的探讨正畸患者隐形矫治中采用不同附件的临床效果。方法选取2021年1月至2022年10月长沙市口腔医院采用无托槽隐形矫治器治疗的60例正畸患者,根据患者隐形矫治器使用中附件类型的不同将其分为优化组和传统组,每组30例。优化组采用优化附件,传统组采用传统附件。比较2组患者三维向移动效率、牙周健康指数、正畸美观度及并发症发生情况。结果随访结束后,传统组患者上颌尖牙、第二前磨牙矢状向、横向及垂直向移动距离与优化组比较,差异均无统计学意义(P>0.05);在牙齿角度变化中,优化组患者上颌尖牙和上颌第二前磨牙轴倾、旋转和转矩控制力高于传统组,差异均有统计学意义(P<0.05);2组患者牙周探诊深度、牙龈出血指数、菌斑指数比较,差异无统计学意义(P>0.05);优化组患者红/白美学指数评分[分别为(9.62±0.81)、(10.47±0.53)分]均高于传统组[分别为(8.64±0.72)、(9.78±0.53)分],差异均有统计学意义(P<0.05);2组患者并发症发生率比较,差异无统计学意义(P>0.05)。结论相对于隐形矫治器传统附件在正畸患者中的使用,优化附件对牙齿三维向移动效率的控制力更佳,可在一定程度上改善患者牙齿正畸美观度,且对牙周健康指数和牙齿功能影响较小,同时,在佩戴过程中未有严重并发症的发生,具有一定安全性。

Objective To observe the clinical effect of different attachments in invisible orthodontic treatment for orthodontic patients.Methods A total of 60 orthodontic patients treated with invisible orthodontic appliances at Changsha Stomatological Hospital from January 2021 to October 2022 were selected.They were divided into the optimized group and the traditional group based on different types of accessories used in the invisible appliances,with 30 cases in each group.The optimized group was treated with optimized accessories,while the traditional group was treated with traditional accessories.The three-dimensional movement efficiency,periodontal health index level,orthodontic aesthetics,and incidence of complications were compared between the two groups.Results After follow-up,there was no statistically significant difference in the sagittal,transverse,and vertical movement distance of the traditional group's maxillary canines and second premolars compared to the optimized group(P>0.05).In terms of tooth angle changes,the axial tilt,rotation and torque control forces of maxillary cusp and maxillary second premolar in the optimized group were higher than those in the traditional group,with statistical significance(P<0.05).There was no significant difference in periodontal probing depth,gingival bleeding index and plaque index between the two groups(P>0.05).The red and white aesthetic index in the optimized group[(9.62±0.81),(10.47±0.53)points]was higher than that in the traditional group[(8.64±0.72),(9.78±0.53)points],and the differences were statistically significant(P<0.05).There was no statistically significant difference in the incidence of complications between the two groups(P>0.05).Conclusion Compared with the use of traditional accessories of invisible appliance in orthodontic patients,optimized attachments has better control over the three-dimensional movement efficiency of teeth,which can improve the aesthetic appearance of orthodontic treatment to a certain extent,and has a smaller impact on periodontal health index and tooth function.At the same time,there are no serious complications during the wearing process,which has a certain level of safety.
