From IVOCLAR VIVADENT, Zenostar pre-shaded, high-translucency zirconia provides a strong and versatile restorative solution that meets the high-performance demands of the most challenging cases. The material is ideal for high-strength posterior crowns and bridges, especially when occlusal space is limited. Available in six basic shades that can be easily characterized to accommodate each patient’s individual esthetic needs, Zenostar zirconia resists breakage and offers anti-aging properties, making the material safe and reliable.
The Zenostar zirconia restorations were milled using the Zenotec mini from Ivoclar...See more Vivadent, while the IPS e.max restorations were milled in Zenotec Wax for the pressing technique. An appropriate pre-colored disc of the Zenostar material was selected for milling, after which additional color gradients and incisal effects were created using a water color staining technique on the milled zirconia prior to sintering. The post-sintering result was a nice color gradient and incisal effect directly in the zirconia.
Due to the dark underlying preps, the canines were fabricated from Zenostar zirconia...See more from Ivoclar Vivadent. The software enabled the ceramist to cut back the facial surface by .3mm--his standard cutback for pre-colored Zenostar material--prior to milling.
