Titanium (Ti) and its alloys have been extensively applied as dental implant materials under load-bearing conditions due to their outstanding properties. The purpose of this paper is to investigate the effects of two types of surface modifications; acid etching and plasma spray coating on the surface finish of the titanium alloys. Acid etchings were carried out by varying the types of acids. In the plasma spray, a yttria stabilized zirconia (YSZ) was chosen as a coating material. All treated surfaces were characterised by an X-ray diffraction (XRD), a scanning electron microscope (SEM) and a roughness tester. It was noted that the coated surface with 7.78 µm was significantly rougher than the etched surface, ranging from 0.137 µm - 3.986 µm.
