Evaluation of Surgical Outcomes of Patients Treated With the Surgery First Approach and Aligners

May 3, 2023 updated by: Arthur Cunha, Rio de Janeiro State University
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).
