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.
