Porous polyethylene implants are available that are designed to augment the mandibular ramus and body. They can be used to increase the bigonial distance in patients with normal mandibular anatomy who desire an increase in lower facial width. When used in combination with extended chin implants, they can camouflage the skeletal contour inadequacies associated with class II mandibular deficiency. The implants are placed through intraoral incisions and fixed with titanium screws. In a clinical experience with 11 patients over 6 years, this technique has proven to be safe and effective. (Plast.
