Abstract
The surgery-first approach (SFA) is a novel technique, which has recently gained increasing popularity among orthodontists and surgeons and does not require presurgical orthodontics. The aim of this study was to evaluate the true skeletal mandibular stability after the SFA, while avoiding the effects of post-surgical orthodontic movements, by relying on the relationship between the proximal and distal mandibular segments after osteotomy and fixation. This study included 20 cases with class 3 malocclusion, underwent surgical correction of malocclusion using surgery first approach and two jaw orthognathic surgery. We found that Postsurgical mandibular movements after a SFA have two components (dental and skeletal), and both should be evaluated separately. While the dental movements are extensive, a great mandibular skeletal stability across the line of osteotomy and fixation was found
