Graft Loss Clinical Trial
Official title:
Factors Influencing Bone Block Allograft Resorption. A Randomized Clinical Trial
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.
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.
