10 下顎骨欠損部への二次的血管柄付遊離骨移植における微細形態および微細血管構築の変化について (例会抄録(第431回))

抄録

I investigated microstructural and microvascular changes in a vascular bundle transplanted into the tibia of a rabbit (Group 1) and during the healing process of a mandibular defect in the same animal packed with the secondary living free bone graft from the tibia (Group 2). In Group 1 the transplanted vascular bundles communicated with the pre-existing medullary vessels via the newly-formed capillaries, three weeks after transplantation. In Group 2 establishment of circulation in the pre-existing vessels of the donor was observed five days after transplantation and the donor material was completely fused with the mandible at four weeks. The secondary living free bone graft seems clinically effective for mandibular defects.
