ABSTRACT
Objective:
To compare the changes of soft and hard tissue profiles of the adolescent patients with class II division 1 malocclusion between before and after treated with two different kinds of tooth extraction methods, and to provide the reference for clinical treatment.Methods:
A total of 60 adolescent patients with class II division 1 malocclusion were included, and they were divided into 44/44 group (n=30) and 44/55 group (n= 30) based on different kinds of tooth extraction methods. Four first premolars of the patients in 44/44 group were extracted and 2 maxillary first premolars and 2 mandibular second premolars of the patients in 44/55 group were extracted. The measurement indexes of pre-treatment (Tl) and post-treatment (T2) and their difference values (T2 -Tl) of soft and hard tissues of the adolescent patients were detected by lateral cephalometric radiographs.Results:
As for the hard tissue, compared with before treatment, the Overjet, SNA, ANB, Ul-NA, distance of Ul-NA, Ul-SN, NA-PA, and A-NP of the adolescent patients in two groups after treatment were decreasd (P0. 05).Conclusion:
The changes of soft and hard tissue profiles of the adolescent patients after treated with two different kinds of tooth extraction methods are not significant.
