Celtra® Duo (ZLS) ZIRCONIA-REINFORCED LITHIUM SILICATE (ZLS) BLOCK

One Highly Esthetic Block with Two Processing OptionsDeveloped specifically for CEREC® dentists, Celtra Duo (ZLS) is indicated for single unit posterior and anterior crowns, inlays, onlays, and veneers. Celtra Duo (ZLS) can be processed in two ways, and it’s always up to the clinician to decide which solution is appropriate for the case at hand.

MILL & POLISH or MILL & FIRE — The choice is yours.

ZIRCONIA-REINFORCED LITHIUM SILICATE (ZLS) BLOCK

Celtra Duo (ZLS) is designed to produce excellent esthetic results in two ways:

Option 1: After the restoration has been milled, you have the option to polish it with rubber polishing wheels and points, then seat the restoration, no firing necessary. You also have the option to fire the restoration after polishing, which will impart even greater fracture toughness to the restoration. Firing after polishing only is called “dry firing.”

Option 2: After milling, you have the option to characterize the restoration with glazes and

stains, and then fire the restoration prior to seating it.

The degree of characterization is up to you. Some dentists choose to use spray glaze only, which adds a natural gloss to the restoration. Others choose to use a brush to add stains to the restoration, which will impart additional characterization to grooves, fissures, and cusps for an even more impressive and natural, lifelike appearance.

Whichever route you take, we’re here to help you get started producing strong and beautiful restorations from the very start. The following pages provide a step-by-step overview of the restoration workflow for each Celtra Duo (ZLS) indication: Crowns; Veneers; and Inlays/Onlays. Choose the indication for the case at hand, follow the steps, and you’ll be placing CEREC single-visit restorations in no time.

If they are not already installed, use diamond-coated burs.

Pro tip: After milling, 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.

Apply 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 the fine tip brush.

STEP 3 (Alt)

As an alternative to brush-on glazes, you may use Spray Glaze to impart a natural glossy appearance to the restoration. Be sure to attach the accompanying spray nozzle before use, as the nozzle allows for the accurate application of an extremely thin and uniform coat in seconds.

Pro tip: A little spray goes a long way. Application of the spray glaze can be done over set, unfired stains.

Once the restoration has cooled, to prepare the restoration for cementation, thoroughly clean with 70% ethanol and dry. Apply HF (follow Directions for Use) to intaglio only and allow to soak for 30 seconds (5% HF). Rinse and dry thoroughly and apply Calibra® Silane Coupling Agent and leave undisturbed for 60 seconds. Repeat application if layer has dried up. Evaporate solvent with a strong air stream.

STEP 5STEP 4

Place the restoration on a firing pad before placing it in the CEREC® SpeedFire furnace. Be sure to trim the firing pad to fit the CEREC SpeedFire oven’s pedestal. The CEREC SpeedFire furnace is pre-programmed for firing Celtra Duo (ZLS).

Pro tip: Celtra Duo (ZLS) may be fired in other furnaces, such as the Programat and Vacumat. Always follow the manufacturer’s recommended Celtra Duo (ZLS) firing parameters specific to the type of oven you are using.

Pro tip: Be sure to apply a thin uniform layer of cement to the entire internal surface of the crown.

One of the unique advantages of Celtra Duo (ZLS) is its dual pathway performance: You have a choice of milling and firing, or milling and polishing. Some clinicians prefer to mill, polish, and then place the restoration as is, without adding stain/glaze and firing steps. Others choose to mill, add characterization nuances with stains and glazes, and then fire. Others may choose to do both. And did you know you may also opt to mill, polish and then fire the polished restoration as is, without adding stains and glazes? No other material block allows such an extensive degree of flexibility and freedom as Celtra Duo (ZLS).

• After polishing, if you wish to fire your restoration, resume with STEP 4: Fire

• After polishing, if you do not wish to fire your restoration, resume with STEP 5: Etch and Silanize
