CST™ SLA-Type

CST™ SLA-type of surface formation.
Surface treatment of dental implants by sandblasting with large grid following by acid etching (SLA), pioneered by Straumann Holding AG in early 90th, is until now the most widespread method in the world for formation of surface treatment of dental implants. The method has many variations, through adjusting its general approach to specific tasks of a particular manufacturer.
The method is widely acknowledged as providing the most successful micro-topography of the implants’ surface, though its unability to assure absolute removal of blasting leftovers is recognized as well.
Acronym SLA has become common definition and means practicing this technological approach.
Finish Line has developed CST™ SLA process of its own, including large grid Alumina blasting, three staged acid etching and thorough ultra-sound washing and air drying after every stage. Finish Line operates up to one thousand per day strong production line run for nearly five years, capable to provide tens thousands implants per month for its customers.
The quality of the Finish Line CST™ SLA implants (view PDF Research Report), as evaluated by Scanning Electron Microscope (SEM), X-ray Photoelectron Spectroscopy (XPS) and Optical Profilometry, reveals values as acceptable in the world dental practice , as compared to world-known manufacturers of dental implants (view).

Anode Treatment

Anode treatment beneficiates metal surface through metal dissolving and oxidation. In case no coating is allowed, Anode Treatment is a way to enhance your parts’ surface qualities. more >>

Passivation

Passivation is a classic anode treatment to improve corrosion resistance of metals, comparing to not treated parts, through completing natural formation of metal oxides surface layer. more >>

Bright Passivation

Bright Passivation improves corrosion resistance of metals, comparing to not treated parts, removes spots from previous processing and provides the parts with brighter appearance. more >>

Etching

Etching is an old craft which technically comprises a vigorous anode treatment process, widely exploited in industry. Etching metal surface as a whole makes it uniformly rough and porous more >>

Color Anodizing

Color Anodizing is a unique Titanium only applied process granting to metal surface a wide spectrum of controllable vivid interference colors, which are stable, uniform and repeatable more >>

Surface preparation

Surface preparation ensures the after Anode Treatment surface features as aimed. It includes both quality improving (like de-burring) and surface beneficiation (like surface roughening) more >>

Surface cleaning

Surface Cleaning is an essential completing operation after any Anode Treatment intended washing the surface from leftovers of previous treatment, using purified water at the end step more >>
