|
The author has observed experimentally on the autogonous bone transplantation of the treatment of infrabony pocket. The experimental animals were dogs weighting 16~18kg.
The bone chips were taken from alveolar bone and transplanted to the other side of interdental area where bone was resected and formed cavity of 5X3mm depth.
The dogs were sacrificedon 2nd, 3rd day, 1, 2, 3, 4, 8 and 12th week after transplantation and microscopic, slides were made.
The results are as follows:
1. The resected portion of alveolar bone was filled with blood clot for few days and granulation tissue formed at 1st and 2nd.week. The organization of the area were begun at 3rd week.
2. The organized tissue at 3rd week consisted of collagen bundles on the upper portion of the resected area and loose connective tissue near the bony surface likewise the bone marrow.
3. Osteoblastic and osteoclastic activities were detected on the resected bone surface at 1st to 2nd week. And trabeculation at the surface of resected bone appeared at 3rd week.
4. Osteociasia of the transplanted bone chips were appeared at 1st week, and osteoblastic activities of the transplanted bone chips were at 2nd week.
5. The bone chips were fused and had the lamellated structure. Thick osteoid tissue was formed at 8th week.
