More Brawn Than Beauty

BruxZir®

BruxZir^® Total Zirconia Crowns from Keller Laboratories are a new option for posterior restorations. With these virtually unbreakable all-ceramic crowns, you can provide your patients the strength to withstand severe parafunctional activity and avoid metal restorations. BruxZir is a full contoured zirconia crown or bridge with no porcelain overlay. It is glazed with a smooth surface but designed specifically for the posterior
with more emphasis on brawn than beauty. Tougher than your average crown, BruxZir restorations are sintered for 12 hours at 1,530 degrees creating a nearly indestructible material.
