rainbow Porcelain

rainbow Porcelain (Dental Ceramic) is a porcelain powder dedicated for zirconia, produced by adding very small amounts of various coloring pigments and fluorescent pigments to a compound of feldspar, silica stone, oxides and carbonates. It consists of Liner, Opacious Dentin, Dentin, Enamel, Translucent, Cervical, Margin, Glaze and Stain, and the special porcelain for Opal effect and Fluor effect.

rainbow Porcelain is used by dental technicians for the preparation of all-ceramic crowns and bridges. It is used in prosthetic dentistry by heating the powder mixture in high-temperature furnace to make a hard prosthesis with a glass-like finish.

Indication for Use: rainbow Porcelain is indicated for veneering of zirconia framework and copings for the preparation of crowns and bridges.

Liner
Represents basic shading and enhances the bond strength.
Includes most fluorescent pigment to increase the fluor effect like natural teeth.
Opacious Dentin
Fills up the insufficient area of Pontic or Core
Controls transparency if thickness of Dentin is not enough.
Dentin
It is used to make the shape and represent the shade of prosthesis.
Enamel
Porcelain to express the translucent incisal part of teeth.
Translucent
Porcelain to express the more translucency of incisal part.
Opal Effect
Porcelain to express the translucent incisal part of teeth.
Fluor Effect
Porcelain added more fluorescent materials to increase fluor effect.
Cervical
Porcelain to express the deep color of cervical part and sometimes darker shade of Dentin porcelain is used.
Margin
Porcelain to fit precisely with margin adaptation.
Controls translucency of margin to enhance esthetics.
Gum
Porcelain to express the color of gum.

Features:
    Crack-free Porcelain for Zirconia Core: Perfect combination of thermal expansion coefficients of zirconia and porcelain makes it less probable that a crack will occur.
    Improved Esthetic and Natural Shade and Shade Stability: The opal powder and fluorescent power give an outstanding appearance with natural colors.
    Simple build-up: It enables the production of dental prostheses.
    Excellent workability: The specially processed porcelain powder could be easily handled even by a beginner.
    Enhanced the Bonding Strength with Liner

Standard and Classification:
(1) Applicable standard: ISO6872:2008 Dentistry - ceramic materials
(2) Classification by ISO6872:2008: Type I, Class 1
According to clause 4 of ISO6872, Type I includes ceramic products which are provided as powders, pastes and aerosols, and Type II includes all other forms of ceramic products. All components of rainbow Porcelain are included in ceramic products as powder. Therefore, only Type I can apply to classify all components by ISO6872:2008. And rainbow Porcelain belongs to Class 1 since it is the aesthetic ceramic for coverage of a ceramic substructure.
 
Contraindication:
The application of rainbow Porcelain is contraindicated if:
- The coping of artificial teeth is not made of zirconia materials.
- A crack occurred by compression or tension.
- A patient is likely to be allergic to any ingredients of dental ceramic.
