摘要

Introduction: Sinus grafts are a safe and predictable treatment for increasing bone volume in the posterior maxilla. Common complications include membrane perforations and postoperative infection. Little is published with regard to late-onset infection except as it relates to periimplantitis. This report presents a case of late sequestration of bovine bone mineral graft fully consolidated within host lamellar bone, 8 years postsinus lift. Histology revealed mature lamellar bone encapsulating well-integrated particles of bovine bone material with evidence of devitalization and marrow spaces filled with a dense neutrophil infiltrate and a filamentous mixed microbial flora.
