Changing Mandible Contour Using Computer Designed/Computer Manufactured (CAD/CAM) Alloplastic Implants.

BACKGROUND
The shape of the mandible is the fundamental determinant of the appearance and sexual dimorphism of the lower third of the face. The use of computer-aided design/computer-aided manufactured (CAD/CAM) alloplastic implants provide unparalleled planning and sophistication in the correction of skeletal deficiencies, irregularities and asymmetry.


OBJECTIVES
This study presents the rationale, indications, techniques, and results of the senior author's (MJY) 15-year experience using CAD/CAM alloplastic implants to correct deficiencies and asymmetries of the mandible.


METHODS
A retrospective review of a prospectively maintained database was reviewed of all patients who underwent aesthetic augmentation of the mandible using CAD/CAM alloplastic implants by the senior author.


RESULTS
Over a 15-year period, 123 patients underwent mandibular augmentation using CAD/CAM alloplastic implants. The majority of patients were men (76.4%) with an average age of 31 years (24-63 years). All implants were bilateral. Complications included infection requiring implant removal (2.4%) and patient dissatisfaction resulting in either implant revision (4.1%) or implant removal (2.4%).


CONCLUSIONS
As described here, CAD/CAM alloplastic implants are an effective modality to augment aesthetic mandible contour deficiencies.
