Abstract

An adult female patient aged 34 years and 8 months with Wilson’s disease, a rare autosomal recessive genetic disorder, demonstrated poor chewing ability and facial asymmetry which were worsened gradually since the disease attacked her 10 years ago. She was treated by surgical orthodontics with minimal presurgical orthodontic decompensation. We designed an atypical maxillary anterior subapical osteotomy to close the maxillary incisor pontic space, retract anterior segment of the maxilla, and maintain the dental midline simultaneously. The mandible deviation was corrected by bilateral sagittal split osteotomies. Severe bilateral posterior bite collapses were uprighted effectively and efficiently by miniscrews combined with the adjunctive corticotomies. We also illustrated the decision of treatment modalities, process of orthognathic and orthodontic treatment, and special consideration of surgical approach for this patient and the disease.
