Preparation

CAD/CAM process Try-in Observe the preparation guidelines and minimum thicknesses for preparation

As a preparation for intra-oral imaging, cover the preparation with IPS Contrast Spray Chairside

CAD/CAM process Mill the restoration from IPS e.max CAD LT

Smooth out the attachment points and finish the restoration. Observe the minimum thickness and contact points.

Try in the restoration in its blue state. Check and adjust the occlusion/articulation, if required.

Fill the restoration with IPS Object Fix Putty and press the IPS e.max CAD Crystallization Pin into the Putty material.

Adapt IPS Object Fix Putty to the pin and crown margin. Avoid contamination of the outer side of the restoration.

Remove any contamination from the outer surface of the crown using a brush dampened in water.

Apply individual characterizations using IPS e.max CAD Crystall./ Shades and Stains.

Spray an even and covering layer of IPS e.max CAD Crystall./ Glaze Spray onto the restoration.

Place the restoration in the center of the IPS e.max CAD Crystallization Tray.

Conduct the Combination firing (Crystall./Glaze) in the Programat CS (Program 1).

After cooling, remove the restoration from the auxiliary firing paste.

Clean the restoration with ultrasound in a water bath.

After crystallization, try in the restoration.

Before final placement, etch the restoration for 20 seconds using IPS Ceramic Etching Gel.

Allow Monobond-S to react for 60 seconds and dry with air.

Clean the preparation, rinse with water and blow dry with air.

Apply Multilink Sprint directly into the restoration.
