Patients who will undergo non-extraction surgery will be randomized as 'Pre-Surgery' (SEC) and 'Early Surgery' (EC). Maxillary advancement and mandibular recession will be calculated and a total of 24 patients, 12 in each group, will be included in the study. Millimetric (length, dehiscence, fenestration) and volumetric measurements and soft tissue anthropometric points will be measured in three-dimensional recordings taken at the beginning of treatment (T0) and after debonding (T1). Cone beam computed tomography (CBCT) images will be transferred to NNT and 'Mimics 18.0' programs for measurements. Three-dimensional photographs will be evaluated in the 3dMDvultus program. Shapiro-Wilk test will be used for normality, 'two independent samples t-test' and 'Mann Whitney U test' will be used for intra-group and inter-group comparisons.
