estetic ceram Classic Leucite Glass Ceramic

Product Information: Classic

The Classic is a product by Estetic Ceram AG for dental restorations. It is a ceramic layering material that can be applied to CoCr-metal frameworks. The product is designed to provide sufficient stability and uniform ceramic layer thicknesses with a maximum thickness of 1.5-2 mm. It comes with EMF-Bonder and opaque materials for use during the framework fabrication process. The product is contraindicated for use with ceramic materials outside of the described range of product systems and/or material from another manufacturer, non- approved framework materials, sharp edges and corners on the framework or non- anatomically reduced frame shapes. Dental ceramic and complete ceramic restorations made of glass ceramics are not recommended for patients with bruxism or parafunction.

Product Usage Instructions: Classic

Framework Fabrication

Before using Classic, the CoCr-metal framework must be prepared according to the manufacturer’s instructions. The framework must have a reduced anatomical shape and should provide enough space for an even coating of layering ceramic less than 2 mm. Sharp edges and corners need to be rounded off. It is essential to clean the framework before any porcelain application. Base metal alloys (Cobalt-Chromium and Nickel-Chromium) create water-soluble chromium oxides during every heat treatment process. The oxide must be removed before porcelain application. Clean the framework and the layering with steam or water and brush thoroughly before another porcelain application.

EMF-Bonder

The EMF-Bonder is offered in paste form or as powder in cans. The paste has a ready-to-use consistency and can be applied as a covering layer that does not run off. The powder must be mixed with Estetic Ceram opaque liquid to a paste- like consistency. Before applying the EMF-Bonder, dry the brush for the pastes with water after washing out, moisten it with opaque liquid. Apply the EMF- Bonder with a brush or a glass instrument to the well-cleaned, dry framework in a thin, even layer. After the bonder firing, the EMF-Bonder shows a yellowish colour and an eggshell luster. Then the opaque is applied as usual.

Opaque Bake

The opaques are made in a modern paste form or as powders. The paste has a ready-to-use consistency and can be applied as a covering layer that doesn’t flow. The canned material allows the original consistency to be recreated, simply by mixing it, in case the opaque separates after prolonged storage. After the opaque bake, the layering process can begin.

Instruction for use estetic Ceram ag

classic

The estetic ceram layering ceramic classic is a leucite glass ceramic and is coloured according to the Vita®* classical shade guide A1-D4. The classic layering ceramic is only intended for dental applications and for use by trained professionals.

Indication

• Veneering of suitable dental alloys for metal-ceram technology with a thermal expansion (CTE) of 14 – 15 · 10-6 · K-1 (25 – 500 °C)
  • Precious metal alloys, cast or milled.
  • CoCr or NiCr alloys, cast, milled or laser-sintered.
• The frameworks must have an anatomically reduced shape, have sufficient stability and allow uniform ceramic layer thicknesses with a maximum layer thickness of 1.5 – 2 mm. Edges and tips are to be rounded off. Missing substance must be replaced with an alloy.

Contraindication

•  Combinations with ceramic materials outside of the described range of product systems and/or material from another manufacturer.
• Use of non-approved framework materials.
•  Sharp edges and corners on the framework or non-anatomically reduced frame shapes.
• Dental ceramic and complete ceramic restorations made of glass ceramics are not recommended for patients with bruxism or parafunction.

Framework Fabrication

The fabrication of metal framework (casting, processing, cleaning/oxidation) must be performed according to the manufacturer’s instructions. The framework must have a reduced anatomical shape and should provide enough space for an even coating of layering ceramic < 2 mm. Sharp edges and corners need to be rounded off.

Important note: Cleaning of framework before any porcelain application. Base metal alloys (Cobalt-Chromium and Nickel-Chromium) create water-soluble chromium oxides during every heat treatment process. The oxide must be removed before porcelain application. Clean the framework and the layering with steam or water and brush thoroughly before another porcelain application.

EMF-Bonder

The estetic ceram EMF-Bonder can be used with non-precious metal alloys and reduces the problems of strong oxide formation (green discoloration and flaking of the ceramic). The EMF-Bonder serves as an intermediate layer between cobalt-chromium-based ones Dental alloys and dental ceramics for the reconstruction of metal-ceramic crowns and bridges on cobalt-chrome alloys with a thermal expansion of 14 – 15 × 10-6 x K-1 (25 – 500 °C). The EMF-Bonder is offered in paste form or as powder in cans. The paste has a ready-to-use consistency and can be applied as a covering layer that does not run off. The powder must be mixed with esteticceram opaque liquid to a paste-like consistency.
Please note with all pastes: Water acts as an extreme diluent for the pastes, so please dry the brush for the pastes with water after washing out, and then moisten with opaque liquid before applying. Apply the EMF-Bonder with a brush or a glass instrument to the well-cleaned, dry framework in a thin, even layer.

Bonder Bake
After the bonder has been applied, the restoration is dried under the open oven at a starting temperature of 450 °C for 1-2 minutes. The furnace is then closed with a closing time of 6 minutes and at 80 K/min and vacuum (vacuum on at 450 °C) heated to 980 °C. Holding time: 6 minutes (without vacuum). After the bonder firing, the EMF-Bonder shows a yellowish colour and an eggshell luster. Then the opaque is applied as usual.

Opaque Bake

The opaques are made in a modern paste form or as powders. The paste has a ready-to-use consistency and can be applied as a covering layer that doesn’t flow. The canned material allows the original consistency to be recreated, simply by mixing it, in case the opaque separates after prolonged storage. Please pay attention with all pastes: Water reacts with the paste like an extreme thinning agent, therefore after washing the brush with water please dry it before applying opaque paste to it. Wet the brush before use with opaque liquid only! Apply the first opaque layer onto the clean, dry framework with a flat brush, so that optimum coverage of the metal has been reached (do not suction!).

1st Opaque Bake
After the opaque application, the crown or bridge is dried under the open furnace at a starting temperature of 400 °C for 1-2 minutes. Subsequently the furnace is closed with a 6 minute drying time and heated at a rate of 80 K/min with vacuum (vacuum starting at 450 °C) to 920 °C. Hold time: 2 minute (without vacuum).

2 nd Opaque Bake
Clean the framework and the layering with steam or water and brush thoroughly before another porcelain application. With the application of the second opaque layer the metal frame work is completely covered. Continue with the same procedure as in the first powder opaque bake (920 °C).

Margin Bake

1st Margin Bake
Apply a thin layer of isolation liquid to the shoulder of the die. Mix the margin powder with modeling liquid L2 (margin) to a creamy consistency. Apply margin shoulder ceramic mix in small portions and condense by tapping, suction any excess liquid and dry well. Clean the framework and the layering with steam or water and brush thoroughly before another porcelain application. After the margin application, the crown or bridge is placed on a firing tray at a starting temperature of 400 °C. Subsequently the furnace is closed with a 4 minute closing time and then heated at a rate of 80 K/min with vacuum (vacuum starting at 450 °C) to 900 °C (bake temperature). Hold time: 1 minute without vacuum. After the first bake, place the crown on the die and remove excess materials.

2 nd Margin Bake
A second margin application follows where necessary to optimize the fit. 2nd bake see first bake (900 °C).

Important note: Clean the framework and the layering with steam or water and brush thoroughly before any further porcelain application. For instructions regarding EMF-Bonder firing, see page 5

Dentine/Incisal Bake

Mix ceramic powder (dentine and correlated incisal) with modeling liquid to a creamy consistency. Apply Opaque dentine, dentine and incisal ceramic in small portions to the cervical and interdental area and compact by light vibration. Then more opaque dentine, dentine or incisal is applied according to the tooth layering.
Important note : Clean the framework and the layering with steam or water and brush thoroughly before any further porcelain application.

1st Dentine/Incisal Bake
After the dentine application the crown is placed on a firing tray at a starting temperature of 400 °C. Subsequently the furnace is closed with a 4 minute closing time and then heated at 60 K/min with vacuum (vacuum starting at 450 °C) to 880 °C (bake temperature). Hold time: 1 minute (without vacuum). After the first dentine/incisal firing is complete, trim the crown or bridge and clean. Next, apply a second layer of dentine and incisal for the second dentine firing to complete.

2nd Dentine/Incisal Bake
Same procedure as by the first dentine firing, except with a firing temperature of 870 °C. Any further dentine firings should be carried out at 860 °C. Dentine and incisal firing is of course also possible in one go and is common practice.

 Glaze Finish/Glaze Firing

After completely finishing the surface with a diamond instrument, thoroughly clean the crown or bridge. Apply the glaze LFU paste or the glaze LFU powder mixed with the glaze liquid in a thin layer. For colour characterization, estetic Ceram estetic ceram glaze, shades & stains LFU can be applied and fired. For the firing, please refer to the firing table or to the separate instructions for use.

Glaze Firing
After the stains/glaze application the crown or bridge is placed on a firing tray at a starting temperature of 400 °C. Subsequently the furnace is closed with a 4 minute closing time and then heated at 45 K/min without vacuum to
710 °C (bake temperature). Hold time: 1 minute (without vacuum).

Natural Glaze
Place the crown on a firing tray at a starting temperature of 400 °C. Subsequently close the furnace with a 4 minute closing time and then heat at a rate of 60 K/min with vacuum to 860 °C (bake temperature). Hold time: 1 minute (without vacuum).

 Modeling «nature»

For the simpler «nature» modeling, a thin layer of opaque dentine was applied after the bond and opaque firing to create a deep effect. The tooth body is built up with dentine materials, slightly contoured and covered with incisal material. After the dentine/incisal firing has been completed, shades & stains LFU can be used to highlight aspects of the finished crown that match the tooth colour. The gloss finish was then made with the glaze LFU. (Firing chart on page 25).

Colour Matching

Modeling «individual»

For the «individual» modeling, a thin layer of opaque dentine was applied after the bonder, opaque and margin firing for the optical depth effect. Dentine, modifiers, mamelons and various transpa materials were then applied analogously to the internal structure of natural teeth. After the dentine firing, the crown was completed with various incisal and opal materials and fired. Special colour aspects of the finished crown can be highlighted with the shades & stains LFU. With the glaze LFU the crown got its gloss finish. (Firing chart see page 25)

Coloured Modeling Liquids

If desired, our ceramic powders can be coloured with coloured modeling liquid. This makes it easier for the dental technician to distinguish between the powders when layering.

Monolayer

estetic Ceram classic monolayer materials combine the properties of dentine and incisal. With classic monolayer it is possible to produce all 16 Vita® * tooth shades with coordinated transparency and fluorescence simply, quickly and efficiently with just 3 ceramic materials.
Note: Combination table on page 24.

colour matching

 Monolayer Modeling

In order to obtain the tooth shade A3, the complete tooth shape was enlarged with the classic monolayer M3 and applied to the coping that was opaque with opaquer A3. After firing and finishing the crown, the tooth shade (A3) can be optimally matched to the Vita® * shade guide with estetic ceram shades & stains LFU. (see the matching colour assignment of the shades LFU in the combination table on page 24). The gloss finish was done with the estetic ceram glaze LFU.

Warnings
Use only by trained specialists. Wear protective goggles or suitable face protection when finishing the ceramic restorations. Remove splinters and dust with a suction device or wear a suitable dust mask.

Be careful with the high temperatures when burning. There is a risk of burns! Use oven tongs / tweezers and gloves! Use only in a clean work environment! Contamination of the aids (waxes) and devices (mixing plate, preheating furnace) through residues from alloy processing, especially CoCr or NiCr alloys, can lead to discoloration of the ceramic. Noble metal-free alloys based on cobalt-chromium or nickel-chromium form water-soluble oxides with every fire, which must be removed from the ceramic mass before each application. The framework or framework that has already been veneered must be cleaned thoroughly with steam or under running water with a brush before each ceramic application.
There are different firing conditions due to the different ceramic furnaces on the market. This fact must be taken into account and clarified by the customer on his own responsibility! The specified firing temperatures are only guide values! Recommended storage conditions: 12-38 °C and normal humidity 40-60%. Store in tightly closed original containers. Protect from direct sunlight. Do not put mixed powders back into the can. Use clean, dry instruments for removal.
