Long term effects of skeletal class III treatment: A case report

Objective: although class iii malocclusions’ treatment in pubertal ages is more difficult than the treatment of other malocclusions, the results of the treatment could change especially due to late mandibular growth. this case report describes stabile results of a patient, at the last period of her growth and development, from 14 to 19 years old. our patient was a 14.3 year-old girl at ru period of skeletal maturation. extraorally, the patient had a concave profile, lower midline was symmetric, upper midline was 3mm dislocated to the right from midline of the face. intraorally, class iii canine and molar relations were observed. overjet and overbite measured 2 mm and 3 mm respectively. arch discrepancies were observed –2 mm on maxilla and +5mm on mandible. patient was treated with chin cup and fixed appliances. at the end of the treatment, class i dental and skeletal occlusion and a straight soft tissue profile were achieved.
