Zirconia Solid
Zirconia has a comparable flexural strength to traditional PFM restorations while maintaining a natural and vibrant translucency.
Zirconia Solid is 100% metal-free, a feature that prevents gingival darkening and removes the possibility of exposing metallic margins if gum recession begins. They are naturally esthetic, transmit the color of adjacent teeth, and can be matched to any shade. Zirconia Solid is one of the strongest restorations available for any patient who may have bruxing or grinding issues. Utilizing CAD/CAM technology, it also has a precise marginal fit that can significantly reduce chair time. Since traditional cementation is recommended, there is no need to bond the restoration.

Zirconia High Translucent
Zirconia HT (High Translucent) – At >750 – <1250 MPa, the Zirconia HT is much stronger than porcelain-fused-to-metal (PFM) restorations while maintaining a natural and vibrant translucency.
The product is 100% metal-free, a feature that prevents gingival darkening and removes the possibility of exposing metallic margins if gum recession begins. They are naturally esthetic, transmit the color of adjacent teeth, and can be matched to any shade.
Features
- Superb esthetics
- Life-like translucency
- >750 – <1250 MPa flexural strength
- Highly biocompatible
- Low CTE
- Non-Feldspathic porcelain
Benefits
- Long-term reliability
- Healthy tissue response
- Synthetic ceramics for low wear
- Natural opalescence and translucency
- Versatility of choice
- Hypoallergenic
Indications
- Ideal for anterior or posterior crowns and bridges up to three units
Contraindications
- Contraindicated for inlays/Onlays due to the visibility of the margin
- Contraindicated for veneers due to the thinness of the prep and visibility of the margin
- Contraindicated for certain orthodontically compromised situations
Prep
-
Posterior crowns
-
1.0 mm in the gingival third
-
1.5 mm for axial walls, cusp tips, and the central groove
-
Anterior crowns
-
1.0 mm in the gingival third
-
1.2 to 1.5 mm in the incisal third
-
1.2 mm palatal
Cementation
- Cementation using standard cementation materials and technique
Zirconia Layered
IPS E.Max®
IPS e.max® is an advanced pressed ceramic with even greater strength than the original Empress product. This next-generation ceramic is formulated from lithium disilicate crystals and can be used to create limited bridgework with moderate to heavy connectors. It is monolithic lithium disilicate porcelain that can be pressed or milled as full-contour restoration, or cut back and layered with porcelain.
Features
- Extremely esthetic with beautiful translucence
- 3 times stronger than Empress
- >470 MPa flexural strength
- Lithium Disilicate glass crystals
- Can build on enamel porcelains
- Metal-free
Benefits
- Natural variations of color and translucency
- Superb esthetics
- Can be used anywhere in the mouth for the single-unit crown
- Hypoallergenic
Indications
- Ideal for veneers, thin (no prep) veneers, anterior and posterior crowns, inlays/Onlays, 3 unit anterior bridges, and 3 unit posterior bridges up to the second premolar as an abutment tooth
Contraindications
- Bridge spans exceeding 3 units
- Bridges beyond the second premolar as an abutment tooth
- Not suitable for bruxers or patients with other occlusal dysfunction
Prep
- For anterior crown: Reduction of 1.5-2.0mm at the incisal, 1.5mm lingual, 1.5-1.0mm facial, and 1mm-1.5mm at the cervical of the prep with a deep chamfer or shoulder finish
- For veneers: 1.0-1.5mm facial reduction; thin veneers may require some reduction depending on the bulkiness or orientation of the tooth
- For inlays and Onlays: A shoulder margin with 1.5-2.0mm isthmus width is required, 1.5mm isthmus depth, and a 1.0-1.5mm isthmus floor
Cementation
- Cementation using standard cementation materials and techniques or chemically bonded
- For veneers and inlays, bonding is required and is also recommended for crowns and bridges to achieve maximum strength
