[An experimental study on ceramic xenogenic bone in reconstructing defects of the mandible in rabbits]

In the experiment, fresh bovine bone was chemically defatted and deproteinized, and sintered by high temperature (which is called ceramic bovine bone). The ceramic bovine bone was implanted in the artificial defects of mandibles of 25 rabbits. Observing by X-ray, histology, tetracycline and calcein yellow-green fluorescence double labelling and scanning electric-microscope, we proved that the ceramic bovine bone possessed good bone affinity, promoting new bone calcification, no immunogenic reaction, and was not absorbed within three months. It is a good bone graft material which may be used in clinic.
