The comparison of bone regeneration of implanted bonesubstitute to canine artificial alveolar cleft with and without liquid of bone marrow centesis

骨再生材料是由八磷酸钙（OCP）和猪胶原蛋白复合材料（OCP/Col）制成的。将其植入无法自愈的骨缺损，形成骨桥。但在组织学表现上，与原始基质骨有少数不同。人们认为，在正畸牙齿移动时，形成的骨会造成紊乱。因此，在犬人工牙槽裂术后，我比较了植入骨替代物（OCP/Col）与不植入骨髓穿刺液对犬骨再生的影响。本实验结果评价混合种植组骨形成良好。

The bone regeneration material which is developed in this graduate school of dentistry, it is made of octacalcium phosphate(OCP)and porcine atelocollagen composites (OCP/Col). Implantation of it to bone defect of self-healing impossibility forms bone bridge formation. but, in histological findings, it is the few different from original matrix bone. It was thought that a formed bone gives a disorder on the occasion of tooth movement of orthodontics. So, after making canine artificial alveolar cleft , I compare of bone regeneration of implanted bonesubstitute(OCP/Col)with and without liquid of bone marrow centesis of the dog. The result of this experiment evaluate good bone formation with mixed implant group.
