Classification Case report
  • ABSTRACT
  • TITLE
Objectives
In  this  case  report,  the  comprehensive  treatment  of  a  patient  with  skeletal  class  III malocclusion and severe roll asymmetry is presented.
Case
This case report describes a successful treatment of a 25-year-old female with skeletal class III malocclusion as well as lip and occlusal cant to left side. The treatment plan included (1) bonding in both arches, (2) preforming Le Fort I 1-piece osteotomy and bilateral sagittal split osteotomy, genioplasty and right mandible contouring to correct the displaced and asymmetrical sizes of the maxilla and mandible, (3) postsurgical correction of malocclusion, and (4) left mandibular grafting to correct the asymmetrical size of the mandible. The orthognathic surgery was planned with virtual surgical planning. Patient-fitted and customized allogeneic bone block was designed and manufactured based on the patient’s virtual 3D model. Treatment was concluded with detailed orthodontic finishing. Optimum esthetic results were achieved with 2 specialties and the use of state-of-the-art technology.
Discussion and summary
Surgical-orthodontic treatment of skeletal class III malocclusion and severe roll asymmetry is always a challenge. Precise diagnosis and proper treatment plan are essential. In this case report, we showed a comprehensive treatment approach to achieve the patient’s esthetic demands with use of orthognathic surgery and CAD/CAM bone graft.
