| Abstract | ||
| Background: Proplast is a material designed for tissue implantation commercially available through the Dow-corning Corporation. It is a gray black laminated felt of vitreous or glassy carbon and Teflon (polytetrafluoroethylene). The vitreous carbon also called hyperpure or elemental carbon or pyrolytic graphite, a pure molecular form of carbon that is pyrolytically derived from hydrocarbon such as rayon. Proplast was 1st prepared by Homsy in 1970, invented in 1968 especially for surgical implantation. It's manufactured as a tin felt sheet which is then layered and rolled under high heat and pressure to form the laminated block in common clinical use. Objective: To evaluate the Proplast implant material in restoration of facial bony contour. Methods: There were a total of 18 cases with proplast implant insertion. The mean age of the patients was 27.9 years. The range was 18-35 years. Data was obtained by prospective study and follow-up records of patients with the proplast implant at the department of maxillofacial surgery at Al-Kadhimiya Teaching Hospital for 6 years follow-up duration from 2000-2006. Result: Proplast is a useful implant material for the restoration of facial bony contour (success rate was 88.9%). Sixteen implants were judges to be stable (88.8%), and 2 implants (11.2%) were judged to be unstable (removed) due to infection. In the two infected cases the fixation was done by wire fixation instead if suture fixation or spontaneous fixation with an intraoral approach. Of these 16 stable implants 3 were mobile (18.75%) and 13 implants were immobile (81.25%), and this is appeared to depend on the technique of proplast insertion. Conclusion: Proplast is a useful implant material for the restoration of facial contour, There are some technical difficulties, when it is inserted over areas that are convex such as the malar prominence and orbital margins, in that it is difficult to eliminate the edge effect, but this can be overcome by proper feathering of the edges of the implant with a sharp scalpel.
