Different strength zones within one disc
Suitable for digital CAD/CAM workflows

Applications:Anterior aesthetic restorations,Posterior crowns,Bridges,Full-contour zirconia restorations

Wear Properties of High Translucent Zirconia

Zirconia is a very hard material and some clinicians assume that this material is abrasive to opposing dentition. This isn't necessarily correct as the abrasive nature of the material is determined by its smoothness. It is possible to avoid excessive abrasion by ensuring zirconia restorations are fabricated with a smooth surface. In comparison, glass ceramics, while being more translucent, have two-thirds less flexural strength when compared to zirconia.

When to Choose High-Translucent Zirconia

High-translucent zirconia Restorations: single anterior and posterior crowns, for bridges up to three units, and for implant crowns.

Its use is not always recommended for patients with bruxism. Like all zirconia restorations, high-translucent zirconia is biocompatible, plaque resistant, and a great metal-free alternative to PFMs.
