Alveolar ridge preservation with deproteinized bovine bone mineral and xenogenic collagen matrix: a 12 months clinical and histomorphometric case series study

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) and to clinically and histologically analyze the alveolar bone healing at 12 months prior to dental implant placement. Six patients underwent implant placement and bone biopsy 12 months following ARP. At 12 months, DBBM granules represented 29.52% ± 6.09 of the specimens and were embedded to the newly formed bone representing itself the 27.72%±5.64. Data suggest that a 12-months of ARP using DBBM granules covered with a CM may be considered a predictable technique providing favorable conditions for implant placement in anterior maxilla
