“…By contrast, polymers have been broadly utilized in soft and hard tissue engineering, since their properties are determined by not only molecular weight and fabrication method but also constituent elements and chain structure [3,4]. Among these, metallic materials have been more widely used as hard tissue substitutes than ceramics or polymers because of their excellent mechanical properties, chemical stability in physiological conditions, and ductility, which can prevent sudden fracture [5,6]. Given biocompatibility considerations, the most prevalently facilitated metallic materials have been stainless steel (SUS) [7], Co-Cr alloys [8], magnesium (Mg) [9], and titanium and its alloys [10][11][12][13].…”

As biocompatible metallic materials, titanium and its alloys have been widely used in the orthopedic field due to their superior strength, low density, and ease of processing. However, further improvement in biological response is still required for rapid osseointegration. Here, various Ti surface-treatment technologies were applied: hydroxyapatite blasting, sand blasting and acid etching, anodic oxidation, and micro-arc oxidation. The surface characteristics of specimens subjected to these techniques were analyzed in terms of structure, elemental composition, and wettability. The adhesion strength of the coating layer was also assessed for the coated specimens. Biocompatibility was compared via tests of in vitro attachment and proliferation of pre-osteoblast cells.
