Implant Placement in a Patient Presenting Avascular Bone Necrosis: A Histological Report

Patients who are exposed to immunosuppressant medication and antiresorptive therapy such as bisphosphonates present an important risk for developing osteonecrosis, notably in the jaws. Osteonecrosis is a complex disease still not well understood which involve different cell-types. This case reports an implant placement in a 69-year old female who presented an avascular necrotic bone localized in the anterior mandible. The patient had a medical history of liver transplant and osteoporosis. A 14-month follow-up, after implants placement and removal of the necrotic bone, showed a satisfactory healed ridge and soft tissue healing associates with a survival of the implants. In conclusion, it seems that implant surgery is not necessarily contraindicated for patients who presented avascular necrosis of bone.
