Facial defects can result from trauma, treatment of neoplasms, or congenital malformations, and their restoration is still a challenge for both surgeon and prosthodontists. Craniofacial implants can provide many benefits for prosthetic rehabilitation of facial defects; however, accurate placement of extraoral implants is vital for clinical success. Three-dimensional modeling is a novel technique that not only helps the surgeon to evaluate potential bone sites and adjacent structures, but also facilitates planning of the extraoral implant treatment by the prosthodontist. This technical report describes the use of three-dimensional modeling and planning for craniofacial implant placement.
