Treatment of Skeletal Class II Malocclusion with Obstructive Sleep Apnoea using Orthodontic-Surgical Approach

Abstract

In the treatment of skeletal class II malocclusion due to retrognathic mandible, the airway should be considered for the progress and outcome of the treatment. Here we present a case of 30 year old male patient having convex profile with potentially incompetent lips, class II skeletal base with maxillary and mandibular dentoalveolar protrusion, crowding in the maxillary and mandibular arch. He had nocturnal choking, difficulty in breathing while lying down and snoring suggestive of obstructive sleep apnoea. The treatment involved orthodontic-surgical intervention to correct the Obstructive Sleep Apnoea. Bilateral sagittal split osteotomy (BSSO) advancement of 8mm and ge-nioplasty of 4mm was done. The post operative orthodontic treatment included settling the bite, monitoring the relapse, and managing the dental space for future.
