Zenostar T - Monolithic restorations fabricated in the Staining Technique
In this chapter, all the important steps involved in the manufacture of monolithic zirconium oxide restorations are described and
illustrated. In the Staining Technique, the milled full-contour restorations are completed by applying stains and glaze materials. With
the pre-shaded Zenostar T discs, very esthetic results can be achieved with little effort.
The Zenostar T shades T0, T1, T2, T3 and T4 have been especially developed for reproducing the 16 A-D + 4 Bleach shades. The
Zenostar T discs in the shades T sun and T sun chroma are characterized by a warm, reddish basic shade. They can be used as
alternative basic shades to obtain more individualized A and B shades.
Prior to milling, the disc shade is selected based on the respective tooth shade by means of the shade chart. The combination tables
for IPS e.max Stains and the Zenostar Art Module can be found on the pages 48 and 49.
Finishing
Following sintering, the restoration may be refined with suitable instruments. Cooling of the restoration with water is mandatory
when using diamond grinding instruments. Please refer to page 27 for further notes on finishing. It is essential to polish the surfaces
of monolithic restorations. Good polishing, particularly in the occlusal region, protects the opposing teeth from undesired wear.
The functional status of the dynamic occlusion has to be verified at least twice a year and, if necessary, adjusted. When doing this,
make sure that the surface of the ground occlusal surfaces is carefully polished after functional adjustment by grinding, and that
the original condition is restored. Using the Zenostar Polishing Set is recommended.
The optimized "Zenostar Polish" polishing paste enables smooth, high gloss surfaces to be achieved in an easy manner.
