Tomasi C, et al. - Researchers evaluated whether characteristics of the fresh extraction socket site influenced subsequent dimensional alterations and placement of deproteinized bovine mineral in the socket affected volumetric change during healing. Findings suggested a failure of a graft comprised of collagen-enriched deproteinized bovine bone mineral, placed to fill extraction sockets to influence the overall diminution of the ridge that occurred during healing. Apparently, a significant influence of the thickness of the buccal bone wall on volumetric alterations of the edentulous ridge following tooth extraction was noted.
