Principles of Tooth Preparation Practice Test

BruxZir solid zirconia crowns are versatile enough to be used for both front and back teeth, and they can be applied to bridges as well when the clinical situation and manufacturer guidelines allow. The strength of monolithic zirconia provides excellent resistance to fracture in posterior teeth that endure heavy chewing forces, while the esthetic properties and opacity can still yield an satisfactory appearance in the anterior region. Because it remains a durable, single-piece restoration, it also lends itself well to multi-unit restorations, reducing the risk of veneer chipping that can occur with layered porcelains. So, the best choice is that these crowns and bridges can be indicated for both anterior and posterior applications.
