영문 초록

Purpose: The aim of this study is to compare volume and revascularization of autogenous block bone grafts in simultaneously cortical perforation of recipient beds and grafts, and only cortical perforation of recipient beds. Materials and methods: Two block bone in 8mm diameter was harvested in both skull using trephine bur on 20 New Zealand white rabbits. Harvested block bone was grafted on both inferior border of mandible. On the left side(experimental side), cortical bone of recipient beds and graft were perforated, and on the right side(control side), the only recipient bed was perforated. The rabbits had been sacrificed and infused the India ink for the observation of revascularization at 20 day and 40 day after surgery. The specimens were processed for H-E staining and quantitative analysis(independent t-test, p<0.01) was made under an optical microscope. In additional, specimens were processed for the observation of revascularization. Results: After 20 days, more bone volume was observed in experimental group, but no significant difference between two groups(p=0.106). There were significantly more bone volume in the experimental group at 40 days after surgery(p<0.01). After 20 days, more discrete vascular sprouts were observed in experimental side, but no difference at 40 days after surgery. Conclusion: We conclude that the cortical perforation of both the recipient beds and grafts improve revascularization at early stage and overall graft persistence.
