Technical Data

COLOR COMBINATION CHARTS

InSync/Imagine is a versatile and reliable Type 1 low-fusing dental ceramic for layering and characterizing framework materials made of sintered Zirconium Dioxide (ZrO2), Lithium Disilicate, and Titanium (and Titanium alloys).

The material is a fluorescent material that features a highly stable CTE, is easy to handle and offers great optical properties, color and value stability even after multiple firings. The system includes all of the classic VITATM shades.

Cleaning of Coping/Framework

To ensure even coloring, the coping/framework must be clean, free of oils, and completely dry prior to dyeing.

Ķ Touch the framework/restoration only with clean, non-oily hands.

Ķ Remove any milling dust completely from the entire framework/restoration, including the inner surfaces of the crown, e.g., using a soft brush for layered ceramic

Zr Framework Recommendations (cont.)

Dyeing/Shading Liquid Application Process

Lava Plus Dyeing Liquids are recommended for use with Imagine, Lava Plus High Translucency and Jensen HT Zirconia. There is a Lava Plus High Translucency Zirconia Dyeing Liquid available corresponding to every tooth color (e.g., tooth color Vita™ Classical A1 = dyeing liquid A1).

1. Select the Lava Plus High Translucency Zirconia Dyeing Liquid corresponding to the tooth color and fill the immersion container. • Reseal the bottle immediately after use so that the concentration of the dyeing liquid does not change.

2. Use plastic forceps to place the framework/restoration in the immersion container; the coping/bridge must be completely covered by the dyeing liquid.

3. Carefully tilt the immersion container to allow any air bubbles trapped inside a coping to escape.

4. Leave the framework/restoration in the dyeing liquid for 2 minutes, then use plastic forceps to remove it. Dye each coping/framework only once.

5. Remove the excess dyeing liquid from the coping and from around the interdental connectors, e.g., using a cotton swab or an absorbent paper towel, to ensure even coloring. Make sure that no lint from the paper towel remains on the framework or restoration.

6. Follow the manufacturers recommended sintering procedures as different heat rates and temperatures apply.

To achieve the desired final shade, prior to layering ceramic shading/dyeing of the Zirconia substructure may be necessary.
