Step 5: Surface finishing

• General: following the sintering process the surface of zirconia restorations must always be finished.
  
• Polishing: use normal polishing systems for zirconia such as Meisinger. Complete all required steps for the polishing system being used.
  
• For glazing please see next steps.
  

Step-by-step: Dry firing and glazing Celtra Duo in the CEREC SpeedFire

Step 1: Remove the sprue, polish, try-in/adjustments

Afterwards, be sure to clean the restoration thoroughly using soap and water, then blot dry with a clean, lint-free towel. Celtra Duo (ZLS) restorations must be free of dust and debris before glaze is applied and/or before firing.

Step 2 (Optional):  Apply Celtra Universal stains and glazes to add characterization to your restoration.

The Celtra diluting liquid helps thin out the glaze and stains for a smooth and even application with a fine tip brush.

Step 3: Place restoration on a firing pad in the CEREC SpeedFire and start the process "Glazing" using the tablet; afterwards let your restoration cool down

• The occlusal surfaces of the restoration point upwards.
• Be sure to trim the firing pad to fit the CEREC SpeedFire oven’s pedestal.
• Important: Wait until the timer has expired to 0.
• Attention: Do not touch the restoration immediately, because it is extremely hot!
• Use tweezers to place the restoration for at least 2 minutes on the fan-area until cool to the touch.
• After cooling, check the glaze and add a second layer of glaze if necessary.

Step 1: Remove the sprue, polish, try-in/adjustments

• Afterwards, be sure to clean your restoration thoroughly using soap and water, then blot dry with a clean, lint-free towel. Your restoration must be free of dust and debris before glaze is applied.

Step 2: Fill the restoration with CEREC SpeedPaste and put it on a glaze support pin

• Make sure to completely fill your restoration with CEREC SpeedPaste, in order to avoid the intrusion of impurities, which might negatively impact the fit.
• Use the right glaze support pin for your indication:
o Single tooth restorations: Glaze support single unit
o Bridges: Glaze support multi unit

Step 3: Glaze your restoration using VITA AKZENT Plus GLAZE LT Spray

•To ensure correct use, please read and follow the instructions of the manufacturer (VITA Zahnfabrik).

Step 4: Place the restoration in your CEREC SpeedFire furnace and start the process"Glazing" using the tablet; afterwards let your restoration cool down

• The occlusal surfaces of the restoration point upwards.
• A maximum of 3 single-tooth restorations or a 3-unit bridge can be sintered in one go
• Attention: Wait until the timer has expired to 0.
• Important: Do not touch the restoration immediately, because it is extremely hot!
• Please note: The fan is not available for this material.
• After cooling, check the glaze and add a second layer of glaze if necessary.

Step-by-step: Crystallizing/Crystallizing & Glazing VITA Suprinity PC® in the CEREC SpeedFire

Step 1: Remove the sprue, polish, try-in/adjustments

Step 2: Fill your restoration with CEREC SpeedPaste and put it on a glaze support pin

• Only the enclosed CEREC SpeedFire firing supports "glaze support single unit or glaze support multi unit," and may be used for crystallization, combination fi ring (crystallizing / glazing) and glaze firing.
• A small quantity of CEREC SpeedPaste is used for fixing/positioning the restoration on the firing support. Note: The less CEREC SpeedPaste is used, the better the result. However, to avoid direct contact of the firing support with the restoration, a small quantity of CEREC SpeedPaste must be used for fixation.

Step 3: Glaze your restoration using VITA AKZENT Plus GLAZE LT Spray

• To ensure correct use, please read and follow the instructions of the manufacturer (VITA Zahnfabrik).

Step 4: Place your restoration in your CEREC SpeedFire furnace and start the process"Crystallizing/ Crystallizing & Glazing" using the tablet; afterwards let your restoration cool down

• The occlusal surfaces of the restoration point upwards.
• The maximum number of 3 crowns must not be exceeded.
• The maximum firing chamber size must be observed.
• Attention: Wait until the timer has expired to 0.
• Important: Do not touch the restoration immediately, because it is extremely hot!
• Please note: The fan is not available for this material.
• After cooling, check the glaze and add a second layer of glaze if necessary.
• No more than 3 glaze firings can be carried out.

Processing guidelines by Ivoclar Vivadent

• Do not use IPS e.max CAD Crystall./Add-on materials, as building-up a vacuum is not possible.
  
• Maximum number of IPS e.max CAD objects per firing cycle: 2 single-tooth restorations or 1 bridge.
• Upon the start of the CAD design, open “Shade Selection” and select the desired translucency level, so that the correct firing parameters for the Crystallization/Glaze firing are transmitted to the SpeedFire.
• Do not use the IPS e.max CAD Crystallization Trays and Pins. It is imperative that the Glaze Supports (Dentsply Sirona) are used:
  • Glaze Support Single Unit –> for single-tooth restorations (Note for Abutment Solutions: for abutments or abutment crowns, use the tapered pin to position the restoration).
  • Glaze Support Multi Unit –> for bridges
    
• Select the correct program option depending on the materials used:
  
  • IPS e.max CAD Crystall./Glaze Paste –> Crystallization/Glaze
    
  • IPS e.max CAD Crystall./Glaze Spray –> Crystallization
  • Corrective firing with IPS e.max CAD Crystall./ materials –> Glaze

The factory-calibrated thermal element is constructed for the durability of the furnace. Therefore an exchange is not expected in the first years of operation.

The calibration tool is designed for the fine adjustment of the temperature measurement and is only necessary when the thermo-element in the field has to be changed.

It lasts at least 2000 cycles.

There is no risk. The device has been inspected and sufficiently shielded, so there is no risk of emission.

Yes.

No, this is not possible.

No. 

Depending on the existing patient information in the CEREC SW, either the patient ID or the Patient name will be reconverted into the new order from the new CEREC SW 4.4.1. onwards. Due to data protection regulations the forwarding of the patient data is prohibited in a few countries.

Yes.

We recommend a direct connection of the SpeedFire to your network via the Ethernet connection via LAN cable. In addition, the HW modules can also be used as a radio connection. If these options are not available, the SpeedFire can also be connected via Wi-Fi. For this you also need a USB-Wi-Fi adapter (REF: 6578012). In the case of a Wi-Fi connection, the ad-hoc mode is not permitted, the connection must be made via an access point.

No. 

Yes, the furnace in general can be controlled by several Acs, yet for doing so the CEREC SW 4.4.1 or the respective Premium version are required.

No.  

As soon as the order has been successfully forwarded to the furnace, the SW and the
CEREC AC can be switched off or a new case can be started.

No, this would be an endless list since the processes differ depending on wall thickness, volumes, material and colors.

No, only approved materials by Dentsply Sirona and our material partners can be processed.

Besides different zirconia blocks, Celtra Duo, all CEREC Blocs, all VITABlocs, Vita Suprinity PC and Ivoclar‘s IPS e.max CAD are approved. This means, CEREC SpeedFire is the first 3-in-1 furnace, which enables sintering, crystallization and glazing in one device.

Yes. 

Yes. A longer sintering process for lighter shades is not critical; this means sensitive colors will always be considered when combining colors during the heat treatment.

Yes. 

The wall thickness is an important parameter for the calculation of the processing time during the heat treatment.

Glass ceramic.

Yes, the Programat by Ivoclar and Vacumat by Vita have been validated with Dentsply Sirona materials.

We recommend at least polishing the occlusal before glazing the restoration, this way the surface below the glaze is smooth just in case the glaze will be burst or grind away.
