Foreword
the bridge framework
the full metal crown
the ceramic build-up
 
   
   
  Use pure aluminium oxide - 125μm – to clean the framework.

  Finishing the framework

Cut through the casting sprues using a nylon reinforced separating disc and a holder.

-> Product information
 
 
   
   
  Grind the casting sprue stumps using an aluminium oxide cutting wheel, without contaminating the metal surface, in preparation for bonding with ceramic.

  Cross cut hard metal burs

Super hard metal burs from Dentaurum guarantee quick and effective metal removal of metal with remanium® alloys.

  Finishing the metal surface using a cross cut hard metal bur.  
   
 
Advice: Always use a previously applied grinding instrument on the same types of alloy - especially prior to ceramic bonding!
 
   
 
   
   
  Check the wall thickness using a measuring gauge.  
 
   
   
  The wall thickness of a finished framework should not be less than 0.2 mm.  
 
   
   
  Finishing the framework

The metal collar and parts bordering onto the ceramic build-up must be finished tidily.

-> Product information
 
 
   
   
  Checking the framework

The metal framework fits accurately due to the exact expansion control of the investment material.
