Implants in irradiated bone

ABSTRACT

Cancer therapy for the head and neck malignancy by surgery, radiotherapy, or combined modalities may cause substantial aesthetic and functional problems for the patient. The placement of osseointegrated implants into irradiated bone should only be performed when the predictability of achieving and maintaining osseointergration is high and the risk of developing of osteoradionecrosis is low. There are many benefits that irradiated patients may gain from the use of implants. A successful implant-retained prosthesis is dependent upon the implants in irradiated bone. In that case, the patient were undergone tumor resection and inner-table mandiblectomy due to squamous cell carcinoma of lower posterior gingiva. But 5 year later, the tumor were recurred, we resected the tumor and applied the radiation therapy. After then, we installed four IMZ implants after hyperbaric oxygenation, and made prosthesis using those implants, Until now they don't have any complications.
