Comparison of skeletal and dentoalveolar effects of two different mandibular advancement methods: Conventional technique vs aesthetic approach

Abstract

Purpose The aim of this study was to compare the effects of two different mandibular advancement methods on skeletal, dentoalveolar, and soft tissue structures through cephalometric measurements. Materials and Methods Twenty-four Class II division 1 patients (10 males, 14 female) treated with twin block (TB) or aesthetic approach (EA: Essix plates + Class II elastics) from the archive of our faculty were included in the study. There were 12 individuals in the EA group (mean age: 12.2 ± 1.0) and 12 individuals in the TB group (mean age: 11.8 ± 1.1 years). The skeletal, dentoalveolar, and soft tissue effects of the appliances were evaluated by performing 28 measurements, 14 linear and 14 angular, on the pre and post-treatment cephalometric radiographs. AudaxCeph 5.0 software (Ljubljana, Slovenia) was used for the analysis. A paired sample t-test was employed to assess the changes after one year of utilizing the appliance for each group. Intergroup comparison was performed by using student t test. Results The mandibular base was observed to move forward significantly in both groups (p
