| Abstract: | Three types of dental implants were implanted in the mandibular premolar and the first molar region of five beagle dogs by using immediate implantation (just after ex-traction) and postponed implantation (3 months after extraction) in the semi-function state. The interfaces between implants and bones were studied by x-ray, LM and SEM respectively at week 2,4,8,12 and 24 after implantation. The results showed that osseointegrations were finished after 3 months. Occlusion loading determined bone qualities and directions of wovenbone. We found that osseointegration showed no significant difference in the same dogs and in all implants after 8 weeks. |
