Detailed description

Introduction: A main drawback of bone block graft surgery is the resorption occurring in early stages of healing. The aim of this work was investigate different factors associated with graft resorption in allogeneic bone block graft surgery. Materials and methods: Twenty-eight patients referred for implant placement and with insufficient bucco-lingual (BL) alveolar bone width (\<4 mm) were included in the study. Patients received freeze dried bone allograft (FDBA) blocks of either allogeneic cancellous or cortico-cancellous bone obtained from the iliac crest. The aforementioned groups were compared in regards to bone resorption using General Estimating Equations (GEE) and logistic regression. Demographic data, trabecular bone density, graft site were also analyzed.
