Abstract：Objective This study aimed to investigate the application of temporary anchorage devices (TADs) in malocclusion and to compare the effectiveness of using TADs and conventional anchorage therapy in outcomes and patient quality of life (QOL). Methods One hundred cases of malocclusion patients who underwent orthodontic treatment in the People's Hospital of Qiandongnan Miao and Dong Autonomous Prefecture from January 2017 to December 2023 were se-lected as the study subjects. The patients were divided into an experimental group and a control group by a random sampling method. Patients in the control group were treated with conventional anchorage,and those in the experimental group were treated with TAD anchorage therapy. The space closure of patients in both groups was clinically assessed every 3 weeks,and the QOL of patients was evaluated after 6 months of treatment. Results The maxillary anterior teeth apical retrac-tion in the experimental group was significantly greater than the control group. In the experimental group,maxillary canines were significantly intruded,and the retraction speed was significantly faster (P<0.05). After 6 months of treatment,the QOL scores in the experimental group were significantly higher than the control group (P<0.05). Conclusion TAD anchorage treatment demonstrated superior clinical efficacy for malocclusion. It could be used to achieve overall retraction of maxillary anterior teeth to improve dental alignment and occlusal relationships,and it also improved the QOL of patients.
