Surgery-First Orthognathic Surgery in Skeletal Class III Treatment
Sponsor: Hanoi Medical University
Summary
This study evaluates the efficacy and stability of the "Surgery-First" approach (SF approach) in treating patients with skeletal Class III malocclusion, utilizing a combined retrospective and prospective data collection method. Unlike the conventional method, the SF approach performs orthognathic surgery first to correct the skeletal discrepancy, followed by orthodontic treatment. The study aims to analyze pre-operative dentoskeletal characteristics, arch morphology, and treatment complexity indices, as well as assess the hard and soft tissue changes at 1 week and 1 year post-surgery using digital dental models and Computed Tomography (CT) scans.
