| Research Abstract |
Porous implants were fabricated by micromachining, which were anchored by pores with bone tissue. Porous titanium with many surface pores was implanted into jawbones of beagle dogs. It was shown from SEM observation that new bones were intruded into the surface open pores. In order to investigate an effect of pores on the implants, torque test was carried out using porous titanium filled by resign. The torque of the porous implants is three times higher than that of nonporous ones. Thus, porous implants was effective for dental implants.
