CEREC® Zirconia Key Material Characteristics

Celtra® Duo (ZLS) Key Material Characteristics

CEREC® Zirconia is a Translucent Zirconium Oxide material indicated for the production of fully anatomical posterior and anterior crowns and bridges with a maximum of 2 pontics.

CEREC® Zirconia blocks are available in 10 classic shades*.

CEREC® Zirconia restorations have a flexural strength of 900 MPa after sintering.

CEREC® Zirconia restorations must be sintered first, then characterized with polishing and glazing and fired once again to “set” the glaze, then seated.

Restorations made from CEREC® Zirconia can be fastened non-adhesively with glass ionomer or zinc phosphate cements, or adhesively with self-curing or dual-curing resin cements.

Celtra® Duo (ZLS) is a Zirconia-reinforced Lithium Silicate material indicated for the production of fully anatomical posterior and anterior crowns, inlays, onlays, and veneers.Celtra® Duo (ZLS) blocks are available in the multiple shades in both high and low translucency.Celtra® Duo (ZLS) restorations have a flexural strength of 210 MPa after polishing only, and a flexural strength of 370 MPa after firing.Celtra® Duo (ZLS) has the flexibility to be processed in the following ways: 1. Mill and polish only, then seat; 2. Mill, characterize with glaze and stains, then fire once and seat; 3. Mill and polish, then fire once and seat. Fully adhesive cementation is recommended for all Celtra® Duo (ZLS) indications.

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.

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, do so now using the dia-mond-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.

Celtra® Duo is available in various shades and two translucencies. Choose the one that’s the best match for the case at hand.

STEP 3

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.

Pro tip: Use a glass tile as a surface to mix.

STEP 3 (Alt)

As an alternative to brush-on glazes, you may use the 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.

If polishing only, skip steps 3 and 3 (Alt)–See “Polishing Celtra® Duo (ZLS)” on page 11

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.

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 manufactur-er’s recommended Celtra® Duo (ZLS) firing parameters specific to the type of oven you are using.

STEP 6

For final cementation, apply Prime&Bond* Dental Adhesive and Calibra® Ceram Adhesive Resin Cement according to the manufacturer’s instructions for use.

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

CEREC® Zirconia TRANSLUCENT ZIRCONIUM OXIDE BLOCK

CEREC® Zirconia blocks available in ten classic VITA shades and two sizes for single-unit crowns and multiple-unit bridges. Choose the block that’s the best match for the case at hand.

High Performance Material Available in Ten Classic VITA® ShadesCEREC® Zirconia is a pre-coloured, translucent zirconium oxide material available in ten shades designed to mimic the shade of natural teeth without the addition of liquid colouring.

Whether you choose to mill, sinter, and seat your CEREC® Zirconia restorations as is, or add finishing touches with stains and glazes, we’re here to help you get started producing strong and beautiful restorations from the very start.

STEP 1Choose Your Block

Install the burs “Shaper 25” and “Finisher 10”. These carbide burs are specifically designed to mill CEREC® Zirconia blocks. They won’t work with Celtra® Duo (ZLS) blocks, so when you decide to try Celtra® Duo (ZLS), make sure you switch to the glass ceramic milling burs.

In preparation for polishing and glazing, the crown must first be sintered with the CEREC® SpeedFire furnace. Manual programming is not required, as the CEREC® SpeedFire furnace is pre-programmed for sintering CEREC® Zirconia.

Pro tip: For proper sintering, the crown must be placed upside down inside the furnace chamber.

STEP 2 STEP 3Install Milling Burs Dust Off Milled Crown

STEP 4Sinter

Use a large dusting brush to thoroughly remove any material residue that may have settled on the restoration during the milling process. The surfaces of the crown must be clean and dust-free before sintering.

Push the crown gently onto a firing peg and place it in the center of the CEREC® SpeedFire furnace firing platform. No need to input the firing program by hand, as the CEREC® SpeedFire furnace is pre-programmed to fire CEREC® Zirconia.

Pro tip: After firing, you have the option to polish the crown with rubber polishers to enhance the surface gloss.

STEP 7Fire

CEREC® Zirconia can be finished by polishing or through a combination of polishing and glazing. Using spray glaze will impart a natural gloss to the restoration. Be sure to attach the spray nozzle to the can before use, as the nozzle helps the application of a thin and uniform coat of glaze.


STEP 6Spray Glaze

Fill the inside of the crown with just enough CEREC® SpeedPaste to support the firing peg— do not overfill.

STEP 5Apply firing paste

Speeo

Prior to cementation of the crown, sandblast the internal surfaces in the one-way blasting process with maximum 50µm corundum (AI203) at a pressure less than 2.5 bar. Do not touch the sandblasted surface if at all possible.

Pro tip: Etching with hydrofluoric acid does not produce a retentive surface. Silanization or priming of CEREC® Zirco-nia is not required.

For final cementation, apply Calibra® Universal Self-Adhesive Cement according to the manufacturer’s directions for use.
