Traumatically induced maxillary retrusion--a case report of orthodontic management with the protraction headgear.
A 46-year-old male Caucasian with traumatically induced maxillary retrusion was referred for orthodontic treatment, eight weeks after the original fracture had occurred. Initial surgical reduction and fixation had been successful, when a second traumatic episode was encountered. This resulted in a further degree of posterior maxillary displacement, which was resistant to further surgical reduction. The resulting Class III malocclusion was treated using maxillary protraction headgear, in conjunction with removable orthodontic appliances and intermaxillary traction. Appliances were worn full time and inter-arch correction was achieved in six months. The resulting occlusion proved to be stable following the cessation of active treatment.
