This report presents a histologic assessment of guided bone regeneration for dehiscence defects treated with bovine bone mineral or a combination of autogenous and synthetic bone. The samples were obtained from an autopsy specimen donated by a patient, which is a rare opportunity to evaluate long-term results of guided bone regeneration and osseointegration. The values for bone-to-implant contact were similar in both sites. The augmentation with bovine bone mineral demonstrated bone reconstruction after 1 year, whereas the augmentation with autogenous and synthetic bone failed to maintain the augmented volume, eventually leading to mucosal recession after 5.5 years.
本报告展示了对使用牛骨矿物质或自体骨与合成骨组合治疗裂开性骨缺损的引导骨再生的组织学评估。样本取自一名患者捐赠的尸检标本，这是评估引导骨再生和骨结合长期结果的难得机会。两个部位的骨与种植体接触值相似。使用牛骨矿物质进行的增量在1年后显示出骨重建，而使用自体骨与合成骨进行的增量未能维持增量后的体积，最终在5.5年后导致黏膜退缩。
