Abstract

Maxillomandibular advancement (MMA) is a surgical intervention that reduces the symptoms of obstructive sleep apnea via anterior repositioning of the upper and lower jaws. Pre-operative orthodontic alignment is often a critical component in aiding MMA. Orthodontia are important in intraoperative anchorage for intermaxillary fixation, healthy post-operative occlusion, and post-operative skeletal stability. Sequential clear aligners (SCA) refer to removable orthodontic appliances that are replaced at regular intervals to stimulate dental migration without the use of bonded hardware. These aligners have demonstrated efficacy in aiding orthognathic surgery for dentofacial deformities, which share some technical similarities with MMA for OSA. Here, we explore the treatment protocol for MMA followed by post-operative SCA treatment. Our experiences show that post-operative orthodontic treatment with SCAs results in similarly successful post-operative surgical outcomes given that the patient’s pre-operative occlusion is stable.
