The use of allogeneic bone grafts for alveolar ridge reconstruction has become an often-discussed alternative to augmentation procedures using autografts. Nevertheless, there still is a lack of literature concerning long-time experiences of allografts for alveolar ridge reconstruction. Especially the results of the use of allogeneic bone blocks for mandible reconstructions need to be further investigated.
In this case report, we present the use of customized allogenic bone blocks in Guided Bone Regeneration (GBR) procedures for severely deficient mandibulary bones, the implantation after a healing period of 5 month and the 24-month follow-up data.
Customized allogeneic bone blocks seem to be a successful alternative to augmentations with autologous bone blocks reconstructing highly resorbed mandibulary alveolar ridges, showing highest volume stability and no signs of bone resorption after implant loading.
The application of customized allogeneic bone blocks has shown to be a successful augmentation technique even compared with with autologous bone blocks reconstructing highly resorbed mandibulary alveolar ridges demonstrating no compromises regarding clinical outcome, functionality and esthetics.
同种异体骨移植用于牙槽嵴重建已成为自体移植物增强术的常用替代方法。然而，关于同种异体骨用于牙槽嵴重建的长期经验仍然缺乏文献。特别是同种异体骨块用于下颌骨重建的结果需要进一步研究。
在本病例报告中，我们介绍了在严重缺损下颌骨的引导骨再生（GBR）术中使用定制同种异体骨块的情况，在愈合期 5 个月后进行植入，并随访了 24 个月。
定制同种异体骨块似乎是一种成功的替代自体骨块的方法，可用于重建高度吸收的下颌牙槽嵴，在植入物负载后表现出最高的体积稳定性，没有骨吸收的迹象。
与自体骨块重建高度吸收的下颌牙槽嵴相比，定制同种异体骨块的应用已被证明是一种成功的增强技术，在临床效果、功能和美观方面没有任何妥协。
