Chroma Level 2 stain was applied circumfrentially to the cervical
third and occlusal central, and distal pit areas of each crown to
replicate dentin transparency. Incisal in the Chroma Level 2 as
well was then applied to the cusp tips, marginal ridges and cuspal
incile planes. White was applied sparingly to the cuspal inclines.
The crowns were then spray glazed with Indenco’s Flourescent
Spray glaze. Both restorations were then fired simultaneously
with tooth #15 in Ivoclar’s CS oven on the P3 setting; #14 was fired
in a Vita Vacumat 6000M at theDentsply’s Celtra Duo recom-
mended settings. The crowns were final cemented with a self-
adhesive dual-cure resin cement. They were completed in a single
visit (Fig. 4).
The second illustration of the use of Indenco’s system involves
an indirect casewithmonochromatic Celtra Duo LTA3 block. The
patient presented for a fractured tooth requiring full coverage.
Time restraints prevented a single-visit restoration, so the tooth
was prepared, impressedwith a PVS impressionmaterial and then
temporized with a bis-acryl provisional material. The impression
was poured in a scannable die stone, then scanned with Sirona’s
inEos Blue camera and designed and milled in CEREC inLab 4.3
software. Staining and glazing was peformed in a single-fire appli-
cation in similar fashion to the previous case example. Vita A shade
Chroma Level 3 was placed cervically and occlusally to mimic
dentin, and Incisal Chroma Level 3 was placed on the cusp tips
and cuspal inclines. Whisps of the white stain were then placed on
all cuspal inclines. The crown was then spray glazed with Inden-
co’s Flourescent Spray Glaze and fired according to Dentsply’s
Celtra Duo recommended parameters in a Vita Vacumat 6000M
oven (Figs. 5-6). The crown was final cemented with a self-adhe-
sive dual-cure resin cement (Fig. 7).
As you can see by these clinical examples, the Indenco’s Frit
Systemof stain-and-glaze, alongwith the Flourescent Spray Glaze,
offer the restorative dentist an excellent way to give monochro-
matic ceramic blocks the ability to mimic natural tooth structure,
rivaling laboratory-fabricated restorations.
