The main problem in maxillofacial prosthodontic is retention of prosthesis. The introduction of implants improves prosthesis stability and therefore the quality of the life of the patients. However there are certain problems in everyday practice. There are some specifics of maxillofacial implantology: explicit anatomical relation to the intracranial structures; less bone quality and quantity; more compact bone; irradiated tissues.

Lack of the bone limits use of conventional screw like implants. Also, implant survival in irradiated tissues is much lower. Implantation during the primary surgical procedure is not recommended in patients who will undergo postoperative irradiation. According to the literature, there is no type of implant which could be considered as superior for the implantation in the irradiated bone. Many studies shows, that the increasing of time interval between irradiation and implantation could be of great importance for implant survival. However, there are only few studies performed in humans, so there is no unique protocol concerning to the time of implant placement. Basally oseointegrated implants (disk implants) present excellent alternative in irradiated patients. Patients with auricular, nasal and orbital implant anchored prosthesis will be presented.
