Aesthetic effect analysis of alveolar bone microperforation surgery in orthodontic treatment of patients with moderate to severe dental crowding and anterior lip inclination
Objective To explore and analyze the aesthetic effects of alveolar bone microperforation surgery in orthodontic treatment of patients with moderate to severe dental crowding and anterior lip inclination.Methods From August 2020 to August 2023,97 patients with moderate to severe dental crowding and anterior lip inclination in our hospital were selected,all of whom underwent alveolar bone microperforation surgery.The treatment and aesthetic effects were observed.Results After applying force for one month,the distance of canine movement was(1.93±0.25)mm,and the root resorption was(0.48±0.16)mm;After applying force for 2 months,the distance of canine movement was(3.69±0.47)mm,and the root absorption was(0.57±0.19)mm.After correction,the U1-NA distance and U1-NA angle of patients were lower than before correction,and U1-L1 was higher than before correction(P<0.05).The post treatment Red Aesthetics Index(PES)score was(10.27±1.68),which was higher than the pre treatment score of(13.16±0.59)(P<0.05).The satisfaction rate of patients with the results of orthodontic treatment is 97.94%.Conclusion The use of alveolar bone microperforation surgery in orthodontic treatment for patients with moderate to severe dental crowding and anterior lip inclination can promote orthodontic tooth movement speed,improve orthodontic effect,and will not significantly increase root resorption,resulting in high patient satisfaction.
