Autologous Bone vs. Allograft Bone in Ridge Augmentation

Abstract:

Most of edentulous areas need reconstructive procedures of hard tissues for an ideal implant position. In this perspective, guided bone regeneration with semi-permeable membranes or onlay bone grafts harvested from intra-or extra-oral sites is indicated. Establishment of well regulated tissue banks allows surgeons use of allograft bone. This study compares two clinical cases, where a relevant horizontal deficit was present: first one reconstructed with allograft bone + titanium mesh and the other one with onlay graft + autogenous cortico-spongiosa bone particles, harvested from ramus. In both cases plasma rich in growth factors and fibrin membranes were used in order to enhance graft vascularization and osseous regeneration, as well as faster healing.
