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.
本研究旨在评估脱蛋白牛骨矿物质(DBBM)联合胶原基质(CM)覆盖的牙槽嵴保存(ARP)方案的疗效,并在种植体植入前的 12 个月,通过临床和组织学分析牙槽骨愈合情况。6 名患者接受了骨活检样本采集,并在 ARP 后 12 个月进行了种植体植入。12 个月时,DBBM 颗粒占标本的平均 29.52%±6.09%,并嵌入新形成的骨中,占标本的平均 27.72%±5.64%。数据表明,使用 DBBM 颗粒联合 CM 覆盖的 12 个月 ARP 可被视为一种可预测的技术,为在上颌前牙区植入种植体提供了有利条件。
