INfinite™ Layered Zirconia

With R-Dent’s INfinite™ Layered Zirconia, your patients don’t have to sacrifice strength for esthetics. The R-Dent Elite line of restorations presents an improved take on layered zirconia, featuring esthetics comparable to Lava™ and fractural strength approaching PFM restorations.

INfinite™ Layered Zirconia offers high translucency for the highest quality cosmetic restorations, durability for anterior and posterior indications, and improved margin esthetics. Additionally, its high material strength allows you to maintain more of the natural tooth during preparation.

Additional Information About INfinite™ Layered Zirconia

When traditional porcelain fused to metal crowns won’t deliver the 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. With zirconia’s natural coloration, the coping won’t be visible at the margin if gingiva recedes.


Zirconia is so versatile, it can be used in almost any situation from singles, bridges with any combination of abutments and pontics, inlay bridges, Maryland type bridges and screw-retained implants. Also an esthetic alternative to a PFM with metal occlusion due to limited space.


When esthetic expectations are high and it is important that the restorations match surrounding natural dentition or other existing restorations. If bonding is necessary to retain the restoration, bond strength is weaker and less predictable than other ceramics.


Shoulder preparation not needed. A mild chamfer or a feather-edge margin is good. 1mm buccal, lingual, and occlusal reduction is ideal, but can go to .5mm in some areas when reduction is limited. Minimum occlusal reduction of 0.5 mm; 1 mm is ideal. Adjustments and polishing: Adjust full-contour zirconia crowns and bridges using water and air spray to keep the restoration cool and to avoid microfractures with a fine grit diamond. If using air only, use the lightest touch possible when making adjustments. A football-shaped bur is the most effective for occlusal and lingual surfaces (on anterior teeth); a tapered bur is the ideal choice for buccal and lingual surfaces. Polish full-contour zirconia restorations with the porcelain polishing system of your choice.


Full-contour zirconia may be cemented using a resin reinforced glass ionomer such as RelyX Luting cement. When a greater bond is needed do to the lack of a retentive preparation, use resin cement like RelyX Unicam or RelyX Ultimate. Before cementing all full-contour zirconia crowns, the interior surface of the crown needs to be cleaned with Ivoclean (Ivoclar Vivadent - Amherst, NY). This is critical in assuring maximum bond strength.

Tech Notes

Solid zirconia requires a cast gold type preparation. If adjustments are needed, use zirconia specific diamonds and rubber wheels polishing with diamond paste.
