title: Chin augmentation: Subperiosteal and supraperiosteal implants.
abstract: Implants placed in subperiosteal pockets may erode more deeply into the mandible than those placed above the periosteum. Those positioned supraperiosteally are more likely to shift and certainly are more mobile when pressure is put on the chin. Implants extending laterally far enough to produce a graceful flow of chin into cheek may be difficult to insert through a small incision. A technique is presented in which a two-piece carved silicone rubber implant is placed beneath periosteum laterally and above periosteum centrally. Results to date indicate that firm fixation with lateral tapering adequate to prevent an unpleasantly concentrated chin occurs. Insertion is accomplished easily through a small incision.
