Thin resorbable calcium phosphate coating (BONIT®) on dental implants - DOT GmbH

Dental Coatings - BONIT®


Technology

BONIT® is an electrochemical coating technique developed by DOT. Using this technique, a thin resorbable calcium phosphate coating can be applied on dental implants.
Range of Application

Dental implants
Advantages of the Procedure
  • Outstanding biocompatibility
  • Thin coating
  • Microcrystalline structure, large open surface
  • High solubility and controlled resorption area
  • Complete coverage of porous surfaces and complex implant geometries
  • "Non-line-of-sight" process
  • No flaking of particles or coating delaminations
