Two zirconia coatings by airbrush spraying were used as a new surface treatment on zirconia substrate to create surface roughness and improved bond strength to the veneering ceramic.
Chemical treatments involving fluoride solutions have been proven to create surface roughness and fluoride incorporation favourable to the osseointegration of dental implants by rendering a bioactive implant surface [ 1, 10].
This creates surface roughness and formation of microcracks, creating possibilities for water penetration causing further phase transformation and consequent loss of mechanical strength [ 24– 26].
The surface finishes of the stems were also prepared in a similar way by the manufacturers of the Exeter stem (Stryker Orthopaedics, Hérouville Saint Clair, France) and either polished to tolerances of the current Exeter stem (0.03 µm Ra) or shot-blasted to create surface roughness in excess of 2 µm Ra.

ZnO is intrinsically hydrophilic but can be utilized to create hydrophobic surfaces by creating artificial roughness via microstructuring.
In the current case, where the surrounding media is a uniaxial crystal oriented parallel to the aluminium surface, this creates a surface roughness induced polarization dependence of the plasmonic resonance.
Mathematical models have been created for surface roughness, namely Ra and Rz, through response surface methodology (RS M.
The cellular response to a biomaterial may be enhanced in synthetic polymer formulations by mimicking the surface roughness created by the associated nano-structured extra-cellular matrix components of natural tissue.
The results were compared with the method which created variety of surface roughness by changing the size of the nano-silica particles using the 3 M water/oil repellency test, sliding (tilt) angle, microscopy (SEM), decay of hydrophobicity, self-cleaning, tensile properties, abrasion fastness, and air permeability.
