摘要
Abstract
Objective: This manuscript aimed to compare the difference in sequential and spatial distribution of osteogenesis and angiogenesis between cranial critical-sized defect healing treated with or without bone-substitute materials.Methods:Rats cranial critical-sized defect (CSD) treated with bone-substitute materials (Bio-Oss or Bio-Gide) were regarded as test groups (Bio-Oss group and Bio-Gide group,respectively) and CSD treated without bone-substitute materials was regarded as control group (Natural healing group).Micro-CT and histology analysis were taken to observe new bone formation,while angiography with Microfil? was used to observe angiogenesis in these groups.Results:Both of osteogenesis and angiogenesis were increased in these groups (Natural healing group,Bio-Oss group and Bio-Gide group) with the time-lapse of operation.However,the sequential and spatial distribution of osteogenesis and angiogenesis was different among these groups.The bone and blood vessels regenerated from the periphery to the center of the defect during natural healing.The bone and blood vessels regenerated around the defect and in the area around Bio-Oss.The bone and blood vessels diffusely regenerated in the whole defect area of Bio-Gide group.Conclusion:Osteogenesis is closely related to angiogenesis during bone defect healing.The administration of bone-substitute materials affected the quantity of new bone formation and the distribution of new blood vessels.关键词
