当考虑种植体支持的口腔修复时，拔牙后保留牙槽骨是很重要的。保持牙槽的能力使种植体放置在理想的位置，满足了功能和美学要求。脱蛋白牛骨矿物(DBBM)被用作窝部位填充材料，以保持牙槽骨的形态，而不使用阻塞膜。材料在拔除后立即被移植和包装到窝部位，随后尝试一期软组织闭合。在第二次手术前，牙槽骨脊愈合了9个月，植入了种植体。所有组织学标本均观察到新骨形成。DBBM颗粒附着在高度富含骨细胞的编织和板层状骨上。临床和组织学研究表明，DBBM颗粒是一种有效的生物相容性填充剂，可用于钛固定器植入前牙槽骨保存。需要随机对照临床试验来充分评估这种材料在拔牙后保存牙槽骨中的有效性。
ALVEOLAR RIDGE PRESERVATION FOLLOWING tooth extraction is important when implant-supported oral rehabilitation is considered. The ability to maintain the ridge allows implant placement in an ideal position, fulfilling both functional and esthetic demands. A deproteinized bovine bone mineral (DBBM) was used as a socket site filler material to maintain ridge configuration, without applying an occlusive membrane. The material was grafted and packed onto the socket sites immediately after extractions, and subsequently primary soft tissue closure was attempted. The ridge healed for 9 months before the second surgical procedure, in which the implant was placed. New bone formation was observed in all histological specimens. DBBM particles adhered to a highly osteocyte-rich woven and lamellar-type bone. Clinically and histologically, this report demonstrated DBBM particles to be an effective biocompatible filler agent in extraction sockets for ridge preservation prior to titanium fixture implantation. Randomized controlled clinical trials are needed to fully evaluate the usefulness of this material in ridge preservation after tooth extraction.
