“Refining Post-orthognathic Surgery Facial Contour with Computer Designed/Computer Manufactured (CAD/CAM) Alloplastic Implants”

Background: Le fort I maxillary osteotomies and sagittal split mandibular osteotomies are performed to correct significant dentofacial deformities. The multidimensional skeletal movements, particularly those of large magnitude may result in contour irregularities and facial imbalances. Methods: Three dimensional images were reconstructed from computed tomographic (CT) scans in patients unhappy with their appearances after Le Fort I advancement and/or bilateral sagittal split osteotomies (BSSO). The data from these scans were used to computer design and computer manufacture (CAD/CAM) alloplastic implants for surgical correction of contour irregularities and imbalances. These implants were surgically placed through intraoral and submental incisions and fixed using titanium screws. Results: A total of 21 patients underwent CAD/CAM implant placement. One patient required removal of implants secondary to infection. All other patients were satisfied with their result. Conclusion: The use of CAD/CAM implants and surgical placement has effective in refining appearance in 21 patients over a seven year period with minimal morbidity.
