Effects of bone grafting on maxillary bone healing in the growing pig

The healing of defects of the lateral wall of the maxilla was studied in the growing pig. In Series I the effect on bone healing of AAA-bone and Kiel bone was compared with that of autografts, and in Series II a comparison was made between autografts and AAA-bone implants. It was found that both autografts and AAA-bone implants improved the rate of healing, but the Kiel bone had no effect. Comparison between autografts and AAA-bone implants in Series II did not show any significant differences. Therefore. it was concluded that AAA-bone can be a useful substitute for autografts in grafting procedures in the maxilla.
