Abstract
To evaluate whether clear aligner therapy (CAT) combined with asurgery-early approach can achieve good therapeutic effects in patients with skeletal classIII malocclusion. Thirty consecutive skeletal classIII malocclusion cases treated with clear aligners combined with early surgery were selected. Treatment time, lateral cephalograms and American Board of Orthodontics Objective Grading System (ABO-OGS) scores of the treatment models were measured to evaluate the treatment efficiency, facial profile, and occlusion. The results showed that early surgery was achieved after 7.71months of presurgical orthodontics, on average. ANB decreased by 5.57° (P < 0.001), and STissueN Vert to Pog' decreased by 7.29 mm (P = 0.001), both reaching normal values. The posttreatment ABO-OGS scores were 26.600 on average, meeting its standards. With the assistance of CAT, early surgery can be accomplished in patients with skeletal classIII malocclusion, improving their facial profile and achieving functional occlusion.
