The highly innovative processing technology for non-metal ceramic offered by IPS Empress is creating new potential for producing natural-looking restorations. A. Wohlwend at the University of Zurich further developed the idea of moulding heated ceramic to reproduce accurate ceramic copies of wax models.

Method

In the system, the restoration with all its functional specifications is modeled in wax. Once the wax restoration has been invested and burned out, the heated, softened ceramic is pressed into the mould.

Material

The ceramic is based on glass that contains latent nucleating agents.

In a process comprising several stages, controlled crystallisation is used to produce leucite crystals, measuring a few microns, in the glass matrix.

The semi-finished product or leucite-reinforced ceramic powder is pressed into ingots and sintered. These ingots are the basic components from which dental technicians press restorations.

The constant high quality of the ceramic ingots ensures the accurate reproduction of the physical values of the restorations.

• Outstanding esthetics
  For perfect integration into the natural environment. For restorations to blend with natural teeth.
• Excellent fit because of new thermoplastic processing
  For accurately fitting restorations with optimum marginal seal.
• Very strong crown, veneers, and inlays/onlays
  For long-lasting restorations on which patients can rely.
• Biocompatible ceramic material
  For avoiding gingival trauma and adverse reactions.
• IPS Empress Ceramic wears almost like tooth enamel.

Personalized shade reproduction with the Ivoclar Chromascop universal shade guide
For virtually unlimited creative freedom in fabricating restorations.

High degree of accuracy in shade reproduction as the die material is coordinated with the dentin colour
For determining the dentin shade to avoid shade discrepancies once the restoration is seated.

The logical order and chromatically arranged shade groups of the Chromascop universal shade guide facilitate accurate shade selection. Furthermore, the technician may establish a basis for the reproduction of the tooth shade by selecting the dentin shade of the prepared tooth with the help of the IPS Die Material Shade Selector.
