[Craniofacial prostheses for facial defects].
Craniofacial prostheses (or epitheses) are artificial substitutes for facial defects. Today, prostheses made of silicone are state-of-the-art. They may be fixed anatomically (to already existing structures), mechanically (to spectacle frames), chemically (using adhesives), or surgically (to osseointegrated titanium implants). With the existing extraoral implant systems, prostheses may be securely anchored to the bone regardless of size and location of the defect. The classic atraumatic surgical technique has remained an unchanged prerequisite for successful implantation by avoidance of any heat trauma to the bone. This review outlines the indications and contra-indications as well as advantages and disadvantages of craniofacial prostheses and their retention methods in various facial regions. It summarizes the basic principles of extraoral implantology in respect to implant positioning and the management of children and radiated patients.
