Abstract

Background: A recent systematic review failed to identify one approach for alveolar ridge preservation with superior outcomes. The present case series aimed to evaluate the dimensional changes of sites undergoing Biologically-oriented Alveolar Ridge Preservation (BARP).

Methods: The sockets were filled with a collagen sponge up to 4-5 mm from the most coronal extensions of the crest. Xenograft particles were placed to fill the coronal part. In cases with a compromised buccal/lingual bone, an additional collagen sponge was interposed between the residual cortical bone plate and the mucoperiosteal flap. A collagen sponge was placed to cover the graft.

Results: The study population consisted in 10 extraction sites. Mean change in bone width and vertical ridge position as observed from BARP to re-entry for implant placement were 1.3 mm (14.4%) and 0.6 mm, respectively. The mean distance between buccal and lingual flap healing by secondary intention shifted from 4.9 mm immediately after BARP to 1.8 mm at 2 weeks. No marked differences in the dimensional changes of alveolar ridge were observed between sites with intact or deficient buccal bone plate. All implants were successfully loaded at 2-3 months after placement. In one case, bone augmentation was required.

Conclusions: The stratification of materials proposed in BARP-technique and the additional use of a resorbable device to stabilize graft particles at the buccal aspect provided the conditions for maintaining the ridge dimensions following tooth extraction comparable to the other technique of ARP, restricting the use of graft material to the most coronal portion of the socket.

生物导向的牙槽嵴保存。
背景:最近的一项系统综述未能确定一种具有良好结果的牙槽嵴保存方法。本病例系列旨在评估进行生物定向牙槽嵴保存(BARP)的部位的尺寸变化。方法:在牙冠最冠状延伸处用胶原蛋白海绵填充牙窝4-5 mm。放置异种移植物颗粒填充冠状部分。对于颊/舌骨受损的病例,在残余皮质骨板和粘骨膜瓣之间插入一个额外的胶原海绵。用胶原蛋白海绵覆盖移植物。结果:研究人群包括10个提取点。从BARP到重新进入种植体时观察到的骨宽度和垂直脊位置的平均变化分别为1.3 mm(14.4%)和0.6 mm。口腔和舌瓣经二次意向愈合的平均距离从BARP后立即的4.9 mm转移到2周时的1.8 mm。牙槽嵴的尺寸变化在颊骨板完整或缺失部位无明显差异。所有种植体在放置后2-3个月成功加载。在一个病例中,需要骨增强。结论:barp技术中提出的材料分层和额外使用可吸收装置在颊侧稳定移植物颗粒提供了与其他ARP技术相当的拔牙后维持嵴尺寸的条件,将移植物材料的使用限制在牙槽的最冠状部分。
