Integration of periorbital titanium implants in irradiated bone: Case report and histologic evaluation

Extraoral implants are used increasingly frequently in the wake of ablative tumor surgery and adjuvant radiation or chemotherapy for craniofacial reha bilitation with facial prostheses and epitheses, However, high rates of non integration and implant loss have been reported for extraoral implants, esp ecially for those in the periorbital region following irradiation. This cas e report and corresponding histologic evaluation describe the osseointegrat ion pattern in irradiated periorbital bone, based on the example of 3 retri eved, clinically integrated, stable titanium screw implants.
