Abstract

Guided bone regeneration (GBR) standard protocols call for filling the space underneath the membrane with autogenous bone or a mixture composed of autogenous bone particles and allogeneic bone tissue or heterologous biomaterials. This work describes the case of a GBR performed to restore a vertical bone defect with simultaneous placement of a dental implant in the posterior mandible that was carried out using a high density d-PTFE membrane and corticocancellous porcine-derived bone without the addition of any autogenous bone. Bone regeneration was assessed by histological analysis of a biopsy sample collected from the grafted site nine months after the surgery. Intraoral radiographs taken at follow-up visits showed complete maintenance of the peri-implant bone levels for up to two years after prosthesis delivery. The regenerated site successfully supported functional loading of the implant. The present case report suggests that the use of a heterologous bone substitute alone to restore a vertical defect in a GBR procedure can be as effective as the standard protocol, while avoiding the drawbacks associated with a second surgical site opening.
