A 7-year retrospective study, reporting 3 cases, is presented in which particulate synthetic osseous replacement grafts were placed for ridge preservation and augmentation in the maxillary anterior region after extraction of periodontally hopeless teeth. The ability of an osseous replacement graft to prevent and correct the postextraction atrophy of the alveolar ridge, as well as its esthetic implications in fixed prosthetics, is discussed.
本文呈现了一项为期7年的回顾性研究，报告了3例病例，其中在拔除牙周状况无望保留的牙齿后，使用颗粒状合成骨替代移植物对上颌前部区域进行牙槽嵴保存和增量。文中讨论了骨替代移植物预防和纠正拔牙后牙槽嵴萎缩的能力，以及其在固定修复中的美学意义。
