制成了纯钛两段式简状光面和筒状螺旋种植体，将两种种植体种植在狗的下前磨牙区，观察５个月。结果表明，在观察期间内牙龈无炎症，种植体稳固；Χ片显示种植体与牙槽骨间没有间隙；镜下可见牙龈和种植体间形成上皮附着样结构，骨组织与种植体表面大多呈骨性愈合，简内为骨组织所充满，壁孔处有骨小梁将内外骨段相连。这为临床应用提供了依据。 Made of titanium two-stage light smooth and cylindrical spiral implant, the two implants planted in the dog under the premolars, observed for 5 months. The results showed that during the observation period, there was no inflammation in the gingival and the implant was stable. The hemogram showed no gap between the implant and the alveolar bone. The epithelium attached to the gingival and implant formed microscopically, the surface of the bone and the implant were mostly Bony healing, Jane for the bone tissue is full of trabecular bone wall at the internal and external segments connected. This provides the basis for clinical application.
