Technique IPS Empress® Esthetic
Design the wax-up to optimal function and esthetics. Sprue the wax-ups, invest them and burn them out in the burn-out oven. Press the IPS Empress Esthetic ingot into the mold. After divesting, you will have an exact duplicate in ceramic of the form you had in wax.
Fit the ceramic to the dies, which should require minimal effort. Adjust the contacts between the restorations. Remove the sprues and verify occlusion. At this point, all of the function has been completed within the restoration - all contacts have been verified, and theoretically – the restoration could go into the mouth now but it would be just one color.
Examine the restorations from an esthetic, color and creative aspect. Reduce the incisal edge for layering. With IPS Empress Esthetic only the incisal portion of the tooth needs to be layered. The incisal edge of the tooth is reduced to maintain a minimal thickness of 0.5 mm. The facial aspect is reduced and the shape of the final tooth form is maintained.
Add surface characterization using the IPS Empress Esthetic Veneer Wash Pastes to build up internal effects.
To obtain a three dimensional effect, layer over this using different values and translucencies of clear and opal enamel IPS Empress Esthetic Veneer Materials. Once all the porcelain is layered, fire the restorations in an oven. Recontour the incisal half of the restoration to match the gingival half. Verify occlusion, apply surface characterizations around the gingival margin and then glaze the restoration.
