Multi-Transitional Layer Zirconia

CEREC MTL Zirconia

Strong as ever. Beautiful like never before.

To achieve most perfect results in dental restoration, strength and beauty must go hand in hand. CEREC MTL Zirconia is the solution that provides you with strong, precise restorations that are highly esthetic and natural looking.

CEREC MTL Zirconia from Dentsply Sirona

CEREC MTL Zirconia mono

For fully anatomical anterior and posterior crowns, Inlays, Onlays, Veneers.

CEREC MTL Zirconia medi

For fully anatomical 3-unit anterior and posterior bridges.

Benefits

Why choose CEREC MTL Zircona?

High Esthetics

Due to its high translucency and improved color matching characteristics, CEREC MTL Zirconia meets all esthetic needs.

High Strenghts

The high strength of > 850MPa1 of CEREC MTL Zirconia benefits both, dentist and patient. Restorative treatment is even possible in areas with limited space.

Easy Workflow

Time saving and efficient.

Fast Zirconia Workflow

Most efficient when using the CEREC Primemill & CEREC SpeedFire.

Natural Gradient for great Esthetics

  • Due to its high translucency and high color matching characteristics, CEREC MTL Zirconia meets all esthetic needs.
  • The excellent match with the most commonly used VITA classical Shade enables a most convenient color selection.
  • Natural Gradient: due to the Multitransitional layers of CEREC MTL Zirconia no layers are visible.
  1. Color pigments
  2. Translucency
  3. CEREC MTL Zirconia with a seamless color gradient 
  4. Competitor material with 4 individual layers.

Strength for more confidence

The high strength of > 850MPa of CEREC MTL Zirconia benefits both, dentist and patient. Restorative treatment is even possible in areas with limited space.

CEREC MTL Zirconia is indicated for:

  • fully anatomical anterior and posterior crowns
  • fully anatomical 3-unit anterior and posterior bridges
  • Onlays
  • Inlays
  • Veneers

For Super Fast Milling it is recommended to increase the minimum wall thickness to 0.7 mm.

Facts

40%

Up to 40% lower wall thickness and thus less natural tooth removal compared to competition for crowns allows for a more conservative preparation design and also provides greater flexibility on the restoration.2

82%

of dentists say strenght is a primary reason for using zirconia.3

8 out of 10

dentists fail to meet a 60-minute single-visit goal for their single-unit crown restorations, with long total processing times contributing to longer appointments.3

The CEREC MTL Zirconia Workflow

CEREC MTL Zirkonia Workflow Sketch Step 1

1. Choose the block

In the CEREC SW single unit blocks (mono) and bridge blocks (medi) are included.

Choose the block that’s the best match for the case at hand.

2. Installing milling burs

If using CEREC Primemill in the Super Fast Mode, install the Bur 2.5 ZrO2 CS and Bur 1.0 CS on each side of the milling machine.

If using CEREC MC XL Premium Package, CEREC MC XL, CEREC MC X, install the burs Shaper 25 and Finisher 10.

3. Dust off milled crown

Use the 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.

4. Sinter

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 preprogrammed for sintering CEREC MTL Zirconia.

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

5. Polish

CEREC MTL Zirconia can be finished by polishing or through a combination of polishing and glazing.

Ensure the restoration is properly polished, including the occlusal surface, especially of the areas that are in direct contact with the antagonist. After functional adjusting, re-polish the surfaces to achieve a high gloss.

This ensures potential unwanted abrasion while delivering a quality final restoration.

6. Apply firing paste (optional)

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

Push the crown gently onto a firing peg.

7. Glazing (optional)

The restorations can be glazed with the DS Universal Stain and Glaze System or the DS Universal Spray Glazes (with or without Fluo)

Ensure the restoration is free of contamination and completely dried with oil-free air prior to paint-on or Spray Glaze application.

Pro tip: A little spray goes a long way (approx. 10 cm). Application of the spray glaze can be done over set, unfired stains.

8. Cementation pre-treatment

Prior to cementation of the crown, sandblast the internal surfaces in the one-way blasting process with maximum 50μm corundum (Aliuminiumoxide) at a pressure less than 2.5 bar.

Do not touch the sandblasted surface, if possible.

9. Final cementation

For final cementation, apply Calibra Universal or Calibra Bio Cement according to the manufacturer’s directions for use.
