Dental Coatings - DOTIZE®


Technology

The DOTIZE® anodising process replaces the thin natural oxide film present at the implant surface by a thick oxide layer. Micropores and cracks in the base material are reduced by the anodisation. The DOTIZE® procedure conforms to the standard AMS 2488 (Aerospace Material Specification).
Range of Application

Dental components (abutment screws, fixing screws)
Advantages of the Procedure
  • Increased resistance to wear compared with untreated titanium alloys
  • Higher pre- loading of threaded connections is possible
  • Increase of up to 15 % in the fatigue strength compared with untreated base material
  • No significant changes in the dimensions of the parts
