Correction of Severe Class II Division 1 Malocclusion with Miniscrew Anchorage– A Case Report
A case report describes the camouflage treatment of an adult patient with skeletal Class II jaw base relationship and moderate crowding. A 28-year-old woman presented with chief complaints of protrusive lips and upper front teeth. The clinical examination showed a convex facial profile, retrognathic mandible, excessively proclined upper and lower incisors, large overbite and overjet and a Class II division 1 malocclusion. To correct the facial profile, lip protrusion, large overjet, space deficiency and approximately full Class II relationship, distal movement of the maxillary first molars using miniscrew anchorage along with extraction of the maxillary and mandibular first premolars was planned. The treatment results showed great improvement of facial profile, well aligned dentition and satisfactory occlusion. The mechanism, biomechanical consideration, and factors associate with Class II orthodontic camouflage treatment and molar distalization with miniscrews were discussed.
