Application of Corticotomy Combined with Personalized Lingual Correction in the Treatment of Severe Bimaxillary Protrusion in Adults
Objective To analyze the practical effect of corticotomy combined with personalized lingual correction in the treatment of severe bimaxillary protrusion in adults.Methods 66 patients with severe bimaxillary protrusion admitted to the author's hospital from October 2022 to October 2023 were selected as the observation objects,and all patients were divided into combination group and single group by random number table method,with 33 patients in each group.The single group was treated with personalized lingual correction technique alone,while the combined group was treated with corticotomy combined with personalized lingual correction technique.The patient satisfaction,cephalic image measurement before and after treatment,and the incidence of complications were compared between the two groups.Results The satisfaction of patients in the combination group was higher than that in the single group(P<0.05),and there was no statistical difference in the cephalic shadow measurement data between the two groups before treatment(P>0.05).The SNA value,Wits value,U1-SN value,U1-NA value,U1/NA value,U1-L1 value,FMIA value,coverage value and 0-Mer-Pog of patients in the combination group were better than those in the single group(P<0.05),and there was no statistical significance in the SNB value,ANB value and Wits value between the two groups(P>0.05),and no significant complications occurred in the two groups.Conclusion In the process of orthodontic treatment of severe bimaxillary protrusiform in adults,the use of corticotomy combined with personalized lingual correction technology has a significant promoting effect on strengthening the overall treatment effect and improving patient satisfaction,and the treatment work safety is high.
