The use of autogenous cortical cancellous block grafts to augment the premaxilla is a safe and effective technique to provide adequate bone height and width when reconstructing patients with atrophic premaxilla ridge when endosteal implants are planned. Intraoral bone graft harvests have the advantages of proximity of the donor site to the graft site, convenient surgical access, minimal operative time, and ease of performance in an office setting. The major limitation of these donor sites is the smaller quantity of graft obtainable compared with iliac crest bone harvest sites.
使用自体皮质松质骨块移植来增加前上颌骨是一种安全有效的技术，当计划进行骨内种植体时，可在前上颌骨萎缩嵴重建中提供足够的骨高度和宽度。口内骨移植具有供体部位与移植部位接近、手术入路方便、手术时间短以及在办公室环境中易于操作等优点。这些供体部位的主要局限性是与髂嵴骨采集部位相比，可获得的移植量较小。
