Research Abstract

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.
