Full contour Zenostar restorations
with the Zenostar Art Module
The Zenostar Zr Translucent light, medium, intense, sun and sun chroma work is given
an individual nuance by staining with the Zenostar Stains. On the basis of only five initial
shades, all 16 shades of the classic shade guide can be easily and quickly reproduced.
1. Milling and separating the restorations
Zenostar restorations are made by milling the required work from pre-shaded
Zenostar Zr Translucent blanks. The choice of blanks in the shades light, medium,
intense, sun and sun chroma depends on the required tooth shade as shown in
the shade guide (page 6). When the milling process is complete, the work must be
separated from the blank at the pre-milled positions.
2. Grinding
Gently grind the cervical and body areas with fine-grain emery paper.
Suitable rotary burs can be used to characterize the occlusal surface.
N.B.
Avoid causing any fractures, cracks, edge chipping, sharp edges, indentations or
undersized areas.

N.B.
■ Sinter
programs apply to Zenotec Fire sintering furnaces
■ Please
observe the instructions for use issued with the material
■ Sintering
■ After
conditions apply to all types of dental restorations
changing programs and then sintering without a cover, we recommend inserting a dummy run without contents
4. Polishing
Polish the restoration evenly with a bison bristle brush and Zenostar Polish diamond
polishing paste. Here it is important to always polish the occlusal surface to a high shine;
this helps to prevent abrasion to the opposing teeth.
5. Individualization through staining and glazing
Polierpaste
The final shade nuance is achieved by staining with the stains from the Zenostar Art
Module:
Applying Zenostar Magic Glaze of Zenostar Magic Glaze Flu
Apply the spray glaze thinly and evenly. To get the best results when applying the spray,
hold the work in tweezers and rotate it quickly whilst spraying. Zenostar Magic Glaze
and Zenostar Magic Glaze Flu do not retract from the edges and do not form beads on
polished surfaces. This process is the ideal preparation for the subsequent application of
the Zenostar Art Module stains.
Glaze bake
Carry out a glaze bake to fix the glaze. See the firing program on the next page.
Individual staining
The glazed work is then individualized with the stains of the Zenostar Art Module. This
is followed by a stain bake. See the firing program on the next page. Recommendations
for obtaining the desired shade are given in the table below.
Tip
With the Zenostar Magic Glaze Flu Spray you can put the perfect finishing touches to full contour restorations. The Flu Spray gives
the restoration a fluorescence similar to that of natural dentition, perfectly rounding off the highly successful Zenostar concept.
■ Creates
natural fluorescence for full contour Zenostar restorations.
■ Zenostar
Magic Glaze Flu supports the fluorescent effect of the Zenostar stains, which are equally fluorescent.
■ Zenostar
crowns now feature a fluorescence which is comparable to that obtained by a ceramic build-up and to that of natural
dentition.

Important! Monolithic Zenostar single crowns should be fired with a heat rise of 45 °C / min; monolithic Zenostar bridges should be fired with a heat rise of 15°C / min.
*
Very large items or items with a gingival mask should be allowed to cool for correspondingly longer time: at least 15 to 25 minutes.
Tip
To achieve an especially rich glaze and color depth with 3D effect, an additional glaze bake can be carried out at 930 °C for 2 minutes.
Important
Do not remove work from the furnace whilst it is still hot (> 200 °C) and under no circumstances place it on a cold surface.
Crown and bridge frameworks made from Zenostar Zr
Translucent light, medium, intense, sun and sun chroma
For traditional veneering / layering of zirconia frameworks with Zenoflex dimension or
Zirox veneering ceramic, we recommend using a liner in the corresponding shade or in
the case of Zenoflex dimension, a liner or core stain.
Sintering is carried out as for Zenostar work, i.e. the work can be made in the same
sintering operation.
