With the variety of bone grafting materials available and their use around both natural teeth and dental implants, clinicians need to understand not only basic bone biology but also characteristics of different bone grafting materials to make a proper choice when selecting a material for alveolar bone augmentation and implant treatment. The grafting materials used in the maxillofacial region include autogenous bone, allografts, xenografts, alloplastic or synthetic products, and composite grafts (combination of different materials). This case report describes two frequenly used bone graft materials for socket preservation immediately after extraction: Puros® (Zimmer Dental Inc, www.zimmerdental.com) (allogeneic) and Bio-Oss®(Osteohealth Co, www.osteohealth.comwww.osteohealth.com) (xenogeneic). In the case presented, the authors perform biologic, clinical, radiologic, and histologic analysis of the two grafting materials by placing them side-by-side in the same patient during implant reconstruction. Implant-related phases of bone augmentation are proposed, and an overview of bone grafting materials, specifically Bio-Oss and Puros, is presented.
鉴于现有多种骨移植材料及其在天然牙和牙种植体周围的应用，临床医生不仅需要了解基本的骨生物学知识，还需掌握不同骨移植材料的特性，以便在为牙槽骨增量和种植治疗选择材料时做出恰当的选择。颌面区域使用的移植材料包括自体骨、同种异体骨、异种骨、异体人工或合成产品以及复合移植物（不同材料的组合）。本病例报告描述了拔牙后立即用于牙槽窝保存的两种常用骨移植材料：Puros®（Zimmer Dental Inc，www.zimmerdental.com）（同种异体）和Bio-Oss®（Osteohealth Co，www.osteohealth.comwww.osteohealth.com）（异种）。在本病例中，作者在种植修复过程中将这两种移植材料并排植入同一患者体内，对其进行生物学、临床、放射学和组织学分析。文中提出了与种植相关的骨增量阶段，并对骨移植材料，特别是Bio-Oss和Puros进行了概述。
