This study evaluated the histology results of surgically created bone cavities in thecalvaria of rabbits that were subsequently filled with a HA/ß-TCP composite powder developed inKorea (Dentium, Korea). Ten young adult rabbits were used. Four defects were surgically producedin the calvaria of each rabbit. These defects were classified into 4 groups: the control group, nograft materials; experimental group I, normal saline + graft materials; experimental group II, venousblood + graft materials; and experimental group III, graft materials only. The defects wererandomly filled with the graft materials. The rabbits were sacrificed with at 1-, 2-, 4-, 6- and 8-weeks after surgery. The histology specimens were prepared using the general method with H & Estaining at a 6 ㎛ thickness. Histologically, the degree of new bone formation was similar in allexperimental groups. However, for experimental group II, many cells had gathered around the graftmaterials 1-week after surgery, and new bone formed slightly faster and than in the other groups.No bone formation was observed in the control group. Based on histology findings, the new HA/ß-TCP composite powders appeared to act as a scaffolding material for the regeneration of osseousdefects
