Freeze-dried bone allograft is an interesting treatment alternative to autogenous bone grafts. This clinical report presents a 3-year follow-up of an atrophic maxilla treated with freeze-dried bone allograft. Ridge augmentation was conducted with freeze-dried tibial allografts. Eight implants were used to support a full-arch prosthesis. Three years later, clinical and radiographic follow-up showed bone surrounding the dental implants. Histologic sections showed the presence of biologically active bone. This clinical case supports the use of freeze-dried allograft as an alternative for the reconstruction of the atrophic maxilla.
冻干骨同种异体移植是自体骨移植一种有趣的治疗替代方法。本临床报告展示了一例接受冻干骨同种异体移植治疗的萎缩性上颌骨的3年随访情况。采用冻干胫骨同种异体骨进行牙槽嵴增高术。使用8颗种植体来支持全牙弓修复体。三年后，临床和影像学随访显示种植体周围有骨组织。组织学切片显示存在生物活性骨。该临床病例支持使用冻干同种异体骨作为萎缩性上颌骨重建的替代方法。
