Radiation shielding in oral implantology: a case example.

Patients who are to receive implant therapy and are about to undergo radiation treatment require a means to eliminate, or reduce, the amount of radiation received by the implants and their osseous housing. This requirement is even more important if the implants were recently inserted and osseointegration (Sigma) has not yet been achieved. Lead shielding of the implant sites protects the fixtures and the surrounding bone so that osseointegration can be achieved and maintained.
