title: Maxillofacial prosthetics.
abstract: In the wide variety of maxillofacial deformities resulting from congenital malformation, trauma, or excision of malignant tissue, restoration of function and of facial form is achieved by the replacement of missing soft tissue, repositioning of displaced bone, bone grafting of osseous defects, and restoration of adequate contour. In these cases, the surgeon and prosthodontist must work hand in hand. Prostheses may be temporary or permanent, depending on the extent of deformity, the age of the patient, and the long-term needs. Prostheses can be made from various materials, including methyl methacrylate, silicone, and polyvinyl, but until a substance is found that fulfills all the properties of an ideal prosthesis, the search for suitable substances will continue.
