Step 1: Separate the restoration from the block and remove dust
- A straight handpiece with a diamond wheel or a straight carbide bur can be used for this
- Remove residual milling dust first with pressurized air, then with a large sable brush

Step-by-step: Sintering CEREC MTL Zirconia and CEREC Zirconia+ in the CEREC SpeedFire
Step 2: Place your restoration upside down inside the furnace chamber
In preparation for polishing and glazing, the restoration must first be sintered.
Step 3: Select and start the process "Sintering" on the display; after this process place the restoration on the fan to cool down
- For wet milled restorations: Select process "Drying & Sintering" instead
- Important: Wait until the clock timer has run down to 0
- Danger: Avoid touching the restoration at this time as it is extremely hot!
- Use tweezers to place the restoration for at least 2 minutes on the fan-area until cool to the touch
Step-by-step: Finishing CEREC Zirconia MTL and CEREC Zirconia+ - Polishing and optional Glazing in the CEREC SpeedFire
CEREC MTL Zirconia/CEREC Zirconia+ can be finished by polishing or through a combination of polishing and glazing.
Polishing:
- Ensure the restoration is properly polished, including the occlusal surface, especially the areas that are in direct contact with the antagonist.
- After functional adjusting, re-polish the surfaces to achieve a high gloss.
- This ensures the potential of unwanted abrasion while delivering a final high quality restoration.
Optional Glazing:
Step 1: Fill the restoration with CEREC SpeedPaste and put it on a glaze support pin
- Fill the inside of the crown with just enough CEREC SpeedPaste to support the firing pin – do not overfill.
- Push the crown gently onto a firing pin.
- Single tooth restorations: Glaze support single unit
- Bridges: Glaze support multi unit
Step 2a: Glaze your restoration with DS Universal Spray Glaze
- Ensure that restoration is free of contamination and completely dried with oil-free air prior to glaze application.
- Shake the container well immediately before usage
- Keep the can as upright as possible during the spraying process.
- Apply an even coat of spray from all sides and maintain a distance of 6 – 10 cm (2.5 – 4.0 in) between the nozzle outlet and the restoration surface.
Step 2b: Glaze your restoration with DS Universal Stain & Glaze System
- Ensure that restoration is free of contamination and completely dried with oil-free air prior to glaze application.
- Apply a thin layer of the glaze material all over the crown surface by using a brush (e.g. Pinelo by Dentsply Sirona)
- If a more intensive shade effect is desired, DS Universal Stains can be used
Step 3: Glazing in the CEREC SpeedFire furnace
- Position the support with the restoration centrally on the top door insulation
- Select the “GLAZE” program on the CEREC SpeedFire control panel and allow the unit to cycle
- Important: Wait until the clock timer has run down to 0.
- Danger: Avoid touching the restoration at this time as it is extremely hot!
- Use tweezers to place the restoration for at least 2 minutes on the fan-area until cool to the touch.
