抄録

In three adult dogs,4 molars of mandibular bone were extracted. Three months later, the three bone cavities in the extracted area were prepared.Bone crushed dust at preparation of bone cavities was transplanted into the mesial cavity, and bone smashed tips from the top of the surrounding alveolar bone into the distal cavity, while the central cavity was filled with only blood clot. Tissue specimens at 1,3, and 5 weeks after surgery were made for observation under a light microscope and a polarizing microscope.<br/> 1.New bone trabeculae were not observed after 1 week, in all of the cavities. Bone trabeculae were observed after 3 weeks, and the bone was immature.After 5 weeks, lamellae were obviously observed,and bone was mature.<br/> 2.In the case of blood clot, the trabeculae were slender, and the percentage of occupation of bone was 41.24.87% after 3 weeks, and 42.83.3 after 5 weeks.<br/> 3.In the case of bone crushed dust, the trabeculae were large, and the percentage of occupation of bone was 64.55.34% after 3 weeks, and 71.16.4% after 5 weeks.<br/> 4.In the case of bone smashed tips, the trabeculae were large, as in the case of bone crushed dust. The percentage of occupation of bone was 66.16.45% after 3 weeks, and 65.96.91% after 5 weeks.<br/> 5.At 3 and 5 weeks later, the gross square measure of bone trabecule was significantly larger in the case of bone crushed dust or bone smashed tips, compared with the case of the blood clot(percentage of danger0.1%).<br/>
