HTR polymer facial implants: a five-year clinical experience.
Forty-three patients at two different international sites underwent onlay facial augmentation of the malar, paranasal, and chin regions using 61 HTR polymer preformed implants. All implants were placed intraorally and rigidly fixed with a titanium screw. Over postoperative periods ranging from two to five years, one implant was removed because of infection. Two other implants in patients with rheumatic and connective tissue disease were removed because of persistent pain and erythema. Another peri-implant infection was treated successfully without removal. One-year postoperative radiographs in patients with chin implants demonstrated no underlying bone resorption. This porous polymeric material appears to offer clinical results comparable to other alloplastic materials for onlay facial skeletal augmentation.
