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

采用微机械加工方法制备多孔植入体，通过骨组织孔固定。将表面多孔钛植入比格犬下颌骨。扫描电镜观察发现，新骨侵入表面开孔。为了研究孔洞对植入物的影响，采用孔洞填充的多孔钛材料进行了扭矩测试。多孔植入物的扭矩是非多孔植入物的3倍。因此，多孔种植体是一种有效的种植体。

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.
