Development of Porous Implants anchored by Pores with Bone Tissue by Micromachining

多孔种植体是通过微机械加工制成的，它由带有骨组织的小孔锚定。将多孔多孔钛植入比格犬颌骨内。扫描电子显微镜观察显示，新骨侵入表面开放的孔洞内。为了研究气孔对种植体的影响，用RESIGN填充的多孔钛进行了扭矩测试。多孔型种植体的扭矩是无孔型种植体的三倍。因此，多孔种植体对于牙种植体是有效的。

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.
