Alveolar Ridge Preservation with Deproteinized Bovine Bone Mineral and Xenogeneic Collagen Matrix: A 12-Month Clinical and Histomorphometric Case Series.

Abstract

The aim of the present study was to evaluate the efficacy of alveolar ridge preservation (ARP) protocol using deproteinized bovine bone mineral (DBBM) covered with a collagen matrix (CM), as well as to clinically and histologically analyze the alveolar bone healing at 12 months, prior to implant placement. Six patients had bone biopsy samples harvested and underwent implant placement at 12 months following ARP. At 12 months, DBBM granules represented a mean 29.52% ± 6.09% of the specimens and were embedded in the newly formed bone, which represented a mean 27.72% ± 5.64% of the sample. Data suggest that 12 months of ARP using DBBM granules covered with a CM may be considered a predictable technique providing favorable conditions for implant placement in the anterior maxilla.
