Prescribe BruxZir™ solid zirconia crowns and bridges instead of metal occlusals and cast gold. It’s virtually unbreakable, so it is ideal for bruxers and grinders who have destroyed other restorations in the past. An esthetic alternative to posterior metal occlusal PFM and cast gold restorations, it can be conservatively prepared as thin as 0.5 mm with feather edge margins, much like you would cast gold.
