Clinical observation of using different attachments in invisible orthodontic treatment for orthodontic patients
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 ortho-dontic 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 accesso-ries,while the traditional group was treated with traditional accessories.The three-dimensional movement effi-ciency,periodontal health index level,orthodontic aesthetics,and incidence of complications were compared be-tween 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 signif-icant(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 compli-cations during the wearing process,which has a certain level of safety.
