    Titanium, the gold standard for dental implant materials, is distinguished by its exceptional biocompatibility; however, from a long-term perspective, titanium still lacks sufficient loading strength. Commercially pure titanium with grain size 30 mu m was processed by equal channel angular pressing, and two novel mechanically improved types of titanium material with grain size 4.6 and a parts per thousand currency sign1 A mu m were obtained. The surfaces of these ultra-fine grained titanium samples were further mechanically treated by grinding and polishing, and their surfaces were characterized by atomic force microscopy and contact angle measurement. Osteoblast-like cells and human mesenchymal stem cells were used to evaluate the cytocompatibility of these titanium samples. The cell metabolic activity, cell number, cell area, morphology, and cell adhesion quality during the early stage (2 h) and prolonged cultivation (48 h) were determined.
