摘　　要：采用狗的血供丰富的颌面部为受骨区,用光镜和电镜对自体血管化和非血管化植骨的供骨与受骨连接端进行观察比较。结果表明:血管化植骨的愈合同正常骨折的愈合,非血管化植骨的“爬行替代”过程有其与文献报道不同的特点,即坏死骨引起的炎症反应存在于整个愈合过程中,以连接端骨性愈合(即临床愈合)为标准,血管化和非血管化植骨间不存在差别。This study made a histological comparison (light microscope and transmission electron microscope) between vascularized bone graft (VBG) and non - vascularized bone graft (NVBG) in mandible of dog. The study showed: the healing process of VBG was the same as that of bone fracture. The 'creeping substitution' process of NVBG was imbued with the inflammation induced by dead bone. There was no significant difference on the bone union between VBG and NVBG perhaps for the recipient region was better vascularized.
