The beauty of the natural human smile can be best duplicated with the optical and mechanical properties of all-ceramics and veneers due to the intrinsic nature of its crystals. The right processing of all-ceramics and veneers porcelains is crucial in optimizing the optical behavior of all-porcelain restorations so that they look and feel just like natural teeth.

Picasso Dental Studios technicians are highly trained in advanced techniques for color management allowing us to communicate colors accurately. Advanced techniques can be employed to create optical effects that mimic the properties of the natural dentition. In conjunction with porcelain systems offering a wide gamut of shades, internal and external stains, and proper protocols for color communication that make it possible for Picasso Dental Studios skilled ceramist to produce almost any visual effect.

Through the years, the IPS Empress System has been continuously further developed to keep abreast of the latest trends. As a consequence, decisive enhancements have been made with regard to its aesthetics and function and its processing properties. With more than 33 million restorations having been fabricated with the material to date, the system has gained a reputation for producing long-lasting, natural-looking results and maintaining high quality standards.

The IPS Empress System continues to be synonymous with highly aesthetic fully anatomic single tooth restorations fabricated with all-ceramics.

Zirconia's greatest advantage lies in its strength and resistance to the repetitive loading in the oral cavity. Its unique mechanical properties make it an outstanding restorative choice when maximum strength is a must and optimum aesthetics is also desired. It is the perfect blend between beauty and strength.

There are several different CAD/CAM systems available for the fabrication of Zirconia crowns and bridges. They are not interchangeable and while one system may excel at one specific task it may not be ideal one for another. However, every system has its strengths and weaknesses.
