Guided bone regeneration is a clinical procedure aimed at promoting bone formation at sites where there is severe bone loss. The purpose of this article was to demonstrate reconstruction of deformations of the alveolar process resulting from traumatic injuries to maxillary incisor teeth by guided bone regeneration procedures followed by insertion of dental implants. In both cases, submembranous space-making was stabilized by human demineralized freeze-dried bone. Implant insertion at the sites of bone augmentation resulted in successful restorations. Histologic examination of biopsy samples from the submembranous hard tissue revealed particles of demineralized freeze-dried bone allografts partially surrounded by uninflamed connective tissue and by vital bone adjacent and adhered to the demineralized freeze-dried bone allograft particles.
引导性骨再生是一种临床操作，旨在促进严重骨丢失部位的骨形成。本文的目的是通过引导性骨再生程序，随后植入牙种植体，来证明对上颌切牙创伤性损伤导致的牙槽突变形进行重建。在这两种情况下，人脱矿冻干骨稳定了膜下间隙形成。在骨增量部位植入种植体获得了成功的修复。对膜下硬组织活检样本的组织学检查显示，脱矿冻干骨同种异体移植物颗粒部分被无炎症的结缔组织以及与脱矿冻干骨同种异体移植物颗粒相邻并附着的活骨所包围。
