The purpose of this prospective study is to compare treatment outcomes and the quality of life of skeletal Class III patients treated with conventional fixed appliances and aligners undergoing Surgery-first approach. Data will be collected through validated questionnaires: OQLQ (Orthognathic Quality of Life Questionnaire), OHIP-14 (Oral Health Impact Profile), SF-36 (Medical Outcomes Study 36 - Item Short-Form Health Survey) and IOTN (Index of Orthodontic Treatment Need).
