Ceramir® CAD/CAM T-BLOCK

Ceramir CAD/CAM BLOCK represents a new type of material- it doesn’t fit into to any of the classifications of materials as we know them before.
Ceramir CAD/CAM BLOCK belongs to a different class of material, it is a bio ceramic glass dental material.

The Ceramir T-BLOCK (Enamel block) is a highly translucent block that mimic the natural enamel in terms of optical properties. The final shade of the restoration can be individually adjusted by using a shaded composite cement. The translucency in the T-BLOCK will also adapt colour from the surrounding tooth.

For a highly aesthetic case the Ceramir T-BLOCK will be suited as the underlying dentin shade and together with a shaded composite cement will make it possible to adapt the colour of the final restoration to perfection.

The Ceramir C-BLOCKS are chromatic CAD/CAM blocks that correspond to the shades A0, A1, A2 and A3 in the VITA shade guide.

The Ceramir CAD/CAM T- Block is often the best choice as you can individualize it with your cement. In addition, the block will due to its translucency blend in with the natural tooth.

The C-blocks will however be the best choice if there is a discolouration in the preparation that needs to be covered- the same thing is if you are working with an implant, and the abutment is grey/metal.

The Ceramir i-blocks are CAD/CAM blocks used for precise and reliable fabrication of implant-supported restorations. The i-Blocks fits onto T-base (or similar attachments).

The Ceramir i-Blocks are compatible with Alphatec, BIOMET 3i, Dentsply Sirona, Nobel Biocare, Straumann and many others via the T-base interface.

The i-Block can be used both as a meso-structure and a final crown in implant supported prosthetics

The Ceramir CAD/CAM BLOCKS are manufactured through a process of laser sintering and vitrification. Through this process the glass particles are fused, and the final product consists of a single hybrid glass phase embedded in a resin matrix.

The result is a highly aesthetic material with a translucency similar to felspathic glass ceramic without having the brittleness of a pure ceramic material.

The glassy matrix defines the aesthetic properties of the material. The higher the glass content, the greater the translucency is- which will imitate the properties of enamel.

No, due to a small portion of resin that retains in the material after the manufacturing process the material has flexibility and elasticity. The e-modulus is 20 GPa, which is similar to dentin.

Restorations milled from Ceramir CAD/CAM BLOCKS offers very good mechanical properties.

In the table below you find information of the most important mechanical properties.

In terms of strength- flexural strength as well as compressive strength Ceramir CAD/CAM BLOCK is very similar to values we see from lithium disilicate materials.

What’s interesting and stands out when comparing Ceramir CAD/CAM BLOCKS with ceramic materials is that Ceramir CAD/CAM BLOCK shows bio mimetic properties when looking at resilience / flexibility it is similar to what we see in natural dentin.

The same is when looking at surface hardness- Ceramir CAD/CAM BLOCKS shows 100 HV placing it in right in between the values that we see from natural enamel and natural dentin.

• Anterior and posterior single crowns
• Partial crowns
• Implant supported single crowns.
• Inlays and Onlays
• Veneers

Prepare margin with chamfer or rounded shoulder preparation. For inlays/onlays all internal edges and angles should be rounded. Avoid margins in direct occlusal contact with opposing tooth.

Minimal thickness of the restoration should be 1,5 mm in pit and fissure areas as well as in cusp areas.

For veneers minimal wall thickness is 0,5 mm and it can be reduced down to 0,3 mm in the cervical area.

We recommend that you use diamond burs. Follow the instructions from the device manufacturer.

For best possible result we recommend a wet grinding/milling process.

Ceramir CAD/CAM BLOCKS are compatible with most milling devices. The blocks are available in size 12x14x18 mm.

Block size and milling parameters are standard parameters and are available in all software settings of CAD/CAM Systems.

Select a program used for hybrid blocks.

Pre-set programs for Ceramir CAD/CAM BLOCKS is to be found in milling units from:

• Amann Girrbach
• vhf camfacture
• Orangedental
• DG Shape / Roland

The program can be called edelweiss cad cam block or Ceramir CAD/CAM BLOCKS.

Smooth out the attachment point of the block with a fine grain diamond bur- make sure that proximal contacts are correct. If needed, carry out individual shape adjustments and surface structure.

Final polishing is done by using a rubber cup/ wheel and cotton linen buffs.

We recommend that you use an adhesive resin based shaded composite or composite cement for the cementation.

Follow the instructions for use for the cement manufacturer.

For more detailed information see the Ceramir CAD/CAM BLOCKS IFU.

Yes.

After the try in of the restoration is confirmed, the restoration must be treated with a hydrophobic primer prior to cementation. We recommend that you use Edelweiss Veneer bond. Other bonding materials can be used, for more alternatives, brands- see Ceramir CAD/CAM BLOCKS IFU.

Apply a thin layer of or Edelweiss Veneer bond onto the surface of the restoration, rub the surface for 20 seconds. Gently airdry the surface with an oil free air.

Yes, prepare the tooth using an adhesive composite bonding- follow the instructions for use from the manufacturer.

All excessive cement must be removed.

Occlusal contacts can be adjusted with a suitable grinding instrument, also interproximal areas need to be cleared of any excess cement using a finishing & polishing strip- we recommend you use the ContacEZ finishing strips.

Final polishing of the restoration is achieved using a cotton/linen buff for a high gloss finish.

The glass component blocks like feldspathic glass shows a very high aesthetic look, but they are brittle.

The high strength materials, like zirconia lack the aesthetics- and the composite CAD/CAM blocks lacks both strength and aesthetics, but they have a favourable elasticity.

Ceramir CAD/CAM BLOCK is made of a single glass phase, with only a small amount of resin, this provides the material with similar strength as high strength ceramic materials and aesthetic appearance like glass ceramics without the brittleness. Ceramir CAD/CAM BLOCKS has due to the resin content an elasticity of 20 GPa, similar to dentin.

Ceramir CAD/CAM BLOCK is simply a unique combination of features, strength, aesthetics, and elasticity!

Yes, the Ceramir CAD/CAM restorations can be both modified and repaired without affecting the properties of the material.

If a reparation inside the mouth is necessary, the surface of the restoration shall be roughened with a diamond bur.

Step two, apply a hydrophobic bonding to the surface of the restoration- we recommend the Edelweiss Veneer bond.

Also, other bonding materials can be used- for more detailed information see the IFU for Ceramir CAD/CAM BLOCKS.

Always follow the IFU from the manufacturer of the bonding material.

Apply a resin-based light cured composite to the area that needs to be repaired.

Final polishing of the composite is done by following the Instructions for use from the manufacturer.
