Customizing blue IPS e.max CAD restorations
A variety of different techniques can be used to complete IPS e.max CAD restorations: polishing, staining, cut-back and layering techniques. You can choose any of these options – in line with the motto "all ceramic – all options".
- Polishing technique
- Staining technique on the “blue” restoration
- Staining technique on the “tooth-coloured” restoration
- Cut-back technique
- Layering technique
The following contribution focuses on an efficient and esthetic method of customization - the staining technique on "blue" IPS e.max CAD restorations. We show you the best method of using the staining technique.
Here's how it works:
Step 1 - Preparing
Before you begin with the staining procedure, revise the restoration and secure it on an IPS e.max CAD Crystallization Pin using IPS Object Fix Putty or Flow. You will find detailed information on this step in the "IPS e.max CAD Monolithic Solutions" Instructions for Use.
Step 2 - Selecting the shade
Think about the shades and effects you will want to apply in advance to work in a relaxed way and achieve the best possible results. The IPS e.max CAD Crystall./Shades, Stains shade combination table provides an easy guide to select the correct shades to achieve the desired tooth shade (see IPS e.max CAD Monolithic Solutions Instructions for Use).
Step 3 - Mixing
Dispense the required amounts of Shades, Stains and Glaze onto a mixing pad and mix using a suitable spatula. If required, the ready-to-use pastes may be slightly thinned by adding a small quantity of IPS e.max CAD Crystall./Glaze Liquid. However, make sure that the mixture keeps its paste-like consistency. You can find detailed information about this procedure in the "IPS e.max CAD Monolithic Solutions" Instructions for Use.
Step 4 - Staining
Before staining the restoration, apply an even coating of IPS e.max CAD Crystall./Glaze paste to the entire outer surface of your restoration. Avoid applying the glaze layer too thickly. Avoid pooling.
Now apply the mixed Shades and Stains directly into the unfired glaze layer using a fine brush.
We recommend the following procedure to apply the Shades and Stains:
- To enhance the chroma, apply the tooth colour matching Shade to the buccal surface of the cervical area and middle third as well as into the occlusal fissure area. As an option, Stains sunset/copper may be used for chroma enhancements (•••).
- To imitate the bluish shimmer of the enamel, apply suitable Shade Incisal material to the buccal and occlusal areas of the cusp inclinations (•••).
- To finish the staining procedure, apply Stains white/cream to the marginal ridges and cusps (•••) and Stains mahogany to the fissures (••••) to imitate effects such as "white spots" or "fissure caries".
Avoid applying IPS e.max CAD Crystall./Shades and Stains too thickly!
Step 5 - Crystallization
Once stained, the restoration is crystallized on an IPS e.max CAD Crystallization Tray. You can find detailed information about this procedure in the "IPS e.max CAD Monolithic Solutions" Instructions for Use.
