The restorations presented here were created in collaboration with Dr med. dent. Stefan Paul in Zurich, Switzerland.
Preoperative situation
The patient presented to our laboratory because she wished to have the appearance of her front teeth improved. The enamel defects had previously been built up and enhanced with composite resin. However, the result was not to her satisfaction.

Procedure
Restorations in the anterior region have to fulfil the highest esthetic and functional standards. In this case, the chosen restorative material was IPS e.max Press, a lithium disilicate glass-ceramic.
The central and lateral incisors were to be restored with veneers.
The palatal aspect of the canines had to be included in the restorations in order to ensure proper canine guidance. Therefore, the canines had to be treated with crowns.
The IPS e.max Press MT ingot was selected because of its excellent shade-matching properties.
The ingots were pressed in a Programat EP 5010 G2, taking advantage of the fully automatic press function (FPF).

The restorations were divested and finished.
The prepared crowns and veneers were etched in preparation for cementation.

The outcome clearly demonstrates how state-of-the-art ceramic materials are capable of reproducing the natural tooth structure and what type of restorations can be produced with them.

The IPS e.max Press restorations were successfully placed, and everyone involved in the case was highly satisfied with the result. Due to their true-to-nature translucency and opacity* the ceramic restorations blended in seamlessly with the natural teeth. The outcome clearly demonstrates how state-of-the-art ceramic materials are capable of reproducing the natural tooth structure and what type of restorations can be produced with them.
