The mandibular bone of beagles as well as foxhounds and the border surfaces in the area of implants of dense Al2O3 ceramic were examined by scan electron microscope and optically in undecalcified preparations 4 and 6 months after the start of the experiment. All implants healed without foreign body or inflammatory reaction and exhibited a firm contact with the newly-formed surrounding osseous tissue. The border surface was always formed by osseous tissue and bone marrow and not by connective tissue. The bony border surface presented a casting of the structure proper of the ceramics as well as orderly remodelling. The tooth implants which had in part been under strain for a long time were surrounded by newly formed osteoid bone and supported by bone trabeculi. In the immediate proximity of the surface of the ceramic vital osteophites were found. The gum which was placed in a groove of the step implants showed firm epithelial covering and orderly fibrous texture.
在实验开始4个月和6个月后，通过扫描电子显微镜和光学方法对比格犬以及猎狐犬的下颌骨和致密Al2O3陶瓷植入区域的边缘表面进行了非脱钙标本检查。所有植入物均愈合良好，无异物或炎症反应，与新形成的周围骨组织紧密接触。边缘表面总是由骨组织和骨髓形成，而非结缔组织。骨边缘表面呈现出陶瓷结构本身的铸型以及有序的重塑。部分长期受应力作用的牙种植体被新形成的类骨质骨包围，并由骨小梁支撑。在陶瓷表面紧邻处发现了活跃的骨赘。置于阶梯式种植体凹槽中的牙龈显示出牢固的上皮覆盖和有序的纤维质地。
