Comments

An 18-year-old woman, whose chief complaint was anterior upper teeth protrusion. She presented with a severe skeletal class II malocclusion and high mandibular plane angle, who refused to orthognathic surgery. There was a mild crowding in both arches and abnormal Bolton index in anterior teeth. She was treated with camouflage orthodontics of extraction of 14,24,34,45 using clear aligners. Total treatment time was 40 months. Both her occlusion and facial appearance were significantly improved by the upper and lower teeth retraction . Her soft tissue of chin was significantly apparent compared with her profile of pre-treatment. Her soft tissue of chin was significantly apparent compared with her profile of pre-treatment.

Transverse: Obtain upper midline consistancy with lower midline.
