Abstract

The purpose of this study is to evaluate how it is influence the osseointegration of titanium implants with different geometry. To achieve its purpose we have used modern methods of investigation and has been developed an experimental model study using laboratory rabbits. The number of osteoblastics cells was measured for the three types of bone implant and evaluated the effect of osteoinductive implants that has been applied. We used a group of rabbits and titanium implants with different shape of spirals (straight, knife blades and square) were surgically inserted in the tibia. Process of osseointegration of implants was evaluated after 2, 3 and 4 months. Bone fragments were processed in laboratory and histologically analyzed. In order to measure accurately and to make a comparison of bone creating degree, for each type of treatment, we measured the number of osteoblasts around implants, in an area of 20 µm. The deposit on the surface of bone implants with the knife and saw spiral form determine a more dense organization bone, visible after two months and evidenced by the larger surface of bone cells counted; the fixation of the implants near the cortical bone is good. In the square form implant geometry, organizing bone is thinner in the first three months after insertion, compared with the other two types of implants. Computer tomography scan performed after 4 months after implantation showed uniform bone density in all three types of implants with trabecular bone.
