Case Report

Synthes CMF Orthognathic Reconstruction

Patient profile

– Female patient presented with severe mandibular and maxillary disharmony with long standing TMJ dysfunction and myofascial pain syndrome.

– The patient underwent orthodontic preparation.

– The patient also had posterior condylar resorption from the malocclusion and stress.

Surgical treatment

– The patient underwent a four-piece LeFort I advancement with impaction; a bilateral sagittal split ramus osteotomy with advancement; and a genioplasty advancement.

– Titanium plates and screws were used to achieve rigid internal fixation of the mandible and maxilla.

– Augmentation osteoplasty was performed with DBX at the osteotomy sites and the chin to fill in remaining gaps and to minimize any palpable step-offs.

Postoperative management

The patient recovered well and experienced no postoperative complications.

Why DBX?

DBX was chosen for this case because it molds well to the bone and fills in the osteotomy gaps. Because of the osteoinductive potential*, DBX was used to augment the chin and fill the mental sulcus.
