Cleaning and preparing
Sandblast the finished framework using pure aluminium oxide.
Dentablast Duo
Maintenance free, economical sandblasting machine, includes 2 containers for sandblasting medium.
Advice:
Only use clean, uncontaminated sandblasting medium. Blasting with a slightly coarser grain size will increase the surface area of the metal providing better retention for the ceramic bond.
Sandblast with aluminium oxide grain size 125 μm and low blasting pressure (approx. 2 to 3 bar).
Clean the framework using a steam cleaner.
or as an alternative: Ultrasonic cleaning.
Do not touch the framework with your fingers and use distilled water to clean!
Use an oxide bake to check the framework. Firing times: Final temperature = Opaque – firing temperature of the ceramic to be used, holding time 5 min.
Tip:
An oxide bake can be carried out in order to check the cast metal. An even oxide layer illustrates a clean metal framework. Sandblast and clean the framework before continuing with the ceramic build-up!
