R-Dent’s new “IN” line of restorations presents an improved take
on layered zirconia. With esthetics comparable to Lava™ and
fractural strength approaching monolithic restorations, your
patients don’t need to sacrifice strength for cosmetic restorations.

When traditional porcelain fused to metal crowns won’t deliver the Before
esthetics you desire, rely on R-Dent’s INfinite™ layered zirconia.
A zirconia coping provides full-contour strength, while a cosmetic
layer of porcelain provides the translucency of traditional PFM.
Because of zirconia’s shading and reflective properties, INfinite™
restorations’ translucency surpasses that of conventional PFM. The R-dent INfinite™Layered
Zirconia is a very esthetic option
With zirconia’s natural coloration the coping won’t be visible at the and has become our go to product
margin if gingiva recedes. After when it comes to anterior bridges.

Indications Zirconia Translucency comparison,
shaded & unshaded:
• All bridges up to 48mm 1-Contrast Ratio (%)
• Splinted crowns 35%
• Crowns on Implants 30%
• Cantilever bridges (excluded for patients with bruxism) 25%
• Inlay and onlay bridges (excluded for patients with bruxism) 20%
• Anterior adhesive bridges (excluded for patients with bruxism) 15%
10% Height of the bar represents
5% level of translucency.

Suggested Cementation 0% ™ *Shaded with Zirkonzahn Prettau Color Liquid A3
May be cemented using a resin reinforced glass ionomer such Crystal ™ Zirconia HS Cercon HT
as RelyX Luting cement. When a greater bond is needed do to Crystal “Diamond” Zirconia Zenotec Zr Bridge Translucent R-dent INfinite ™ High Translucency Zirconia
the lack of a retentive preparation, use resin cement like RelyX
Unicam or RelyX Ultimate.

Why Layered Zirconia?
Insurance Codes Layered zirconia restorations combine both the highest esthetics and the
D2740 Crown – Porcelain/Ceramic Substrate strength and flexibility needed for anterior and
D6245 Pontic Porcelain/Ceramic posterior cases. The Zirconia substructure
D6740 Abutment Crown Porcelain/Ceramic typically has a flexural strength of 1200 MPa,
comparable to traditional PFM crowns. Lab tests
have also shown fracture toughness and flexural
strength of zirconia are significantly higher than
any other all-ceramic materials.
