Popis: | Objectives:To evaluate the differences of changes in soft tissue profile and dentoskeletal parameters between different premolar extraction and non-extraction treatment modalities. Materials and Methods: 50 patients with skeletal Class I malocclusion was divided into three groups. Group 1 consisted 17 patients (mean age:16.76±1.68 years) treated with maxillary and mandibular first premolar extractions; Group 2 consisted 16 patients (mean age:15.81±1.19 years) treated with maxillary and mandibular second premolar extractions, and Group 3 consisted 17 patients (mean age:16.29±1.15 years) treated with non-extraction protocol. From the pre-treatment (T0) and post-treatment (T1) cephalometric radiographs, 13 measurements for dentoskeletal and 15 for soft tissue parameters were assessed. To determine changes due to treatment, and to compare differences among the groups, Wilcoxon Signed-Rank and Kruskal-Wallis tests were performed, respectively.Results: Mx1-SN, Mx1-FH, Mx1-NA, IMPA and Md1-NB values decreased significantly in Group 1 and 2, compared to Group 3 (p |
