| Summary: | Objective To explore the impact of maxillary anterior traction combined with rapidarch expansion on parabuccal space and smile aesthetics in patients with skeletal Class Ⅲ malocclusion. Methods The patients with maxillary insufficiency and skeletal Class Ⅲ malocclusion admitted to the First Affiliated Hospital of Bengbu Medical University from January 2021 to June 2023 were retrospectively analyzed. The control group received maxillary protraction treatment, while the experimental group received maxillary protraction combined with rapid arch expansion treatment. The overall treatment effectiveness, buccal corridor area ratio, smile index, smile symmetry ratio, and patient satisfaction with smile aesthetics were compared between the two groups. Results After correction, the total effective rates of the experimental group and the control group were 82.61% and 52.38%, respectively;the area ratio of parabuccal space were 7.10±0.96 and 8.21±1.28, respectively; the smile index were 5.16±0.83 and 6.33±1.03, respectively; the smile symmetry ratio were 0.96±0.18 and 0.83±0.14, respectively; the satisfaction of patients with smile aesthetics were 86.96% and 47.62%, respectively. The differences in the above indexes were statistically significant(P<0.05). Conclusion The maxillary anterior traction combined with rapid arch expansion had a significant effect on the correction of patients with skeletal Class Ⅲ malocclusion, effectively reducing the buccal corridor and enhancing smile aesthetics. |
