BruxZir Restorations

An ideal solution for posteriors instead of PFM metal occlusals or full metal crowns. BruxZir has no porcelain overlay, is virtually unbreakable and resistant to chipping and cracking in the mouth.

Benefits:

STRONG - virtually chip-proof solid zirconia
PRECISION - produced with CAD/CAM technology
CEMENTABLE - conventional or adhesive cementation
BIOCOMPATIBLE - Health Canada approved zirconia
GUARANTEED - a five-year warranty against breakage

WEAR STUDIES

BruxZir crowns and bridges are virtually unbreakable solid zirconia restorations. The results after 100,000 cycles show that the volume loss in mm is virtually identical between glazed IPS e.max and glazed BruxZir Solid Zirconia.

High Strength Crown Options:

BruxZir Solid Zirconia Crown	Full Metal Crown	Porcelain Fused-to-Metal Crown

View this side-by-side comparison of high strength crown options, and then conduct your own analysis of how BruxZir crowns compare visually to traditional PFM and full-cast restorations. Patients do not like the metal showing in their smile, and they will find that BruxZir crowns present a more natural-looking tooth shade.

ADVANTAGES OF BRUXZIR VS. MILLED E.MAX CAD

BruxZir:

Very strong at 1000 MPa
Strength allows more shallow tooth preparation and feather edge margins
Can serve very well in heavy occlusion cases where other materials fail

Milled e.maxCAD:

Can match surrounding dentition very well
Strength at +/- 350MPa shows no failures at one year in molar full-crown restorations

More long-term clinical data are needed to establish indications, contraindications, longevity and failure modes. This information is from the first controlled clinical study comparing performance of e.maxCAD and BruxZir. Currently, BruxZir is less esthetic and e.maxCAD has less strength, but both look acceptable in molars and are serving well without problems.

Fabrication Process:

	STEP 1 - SCANNING Digital impression, or model is scanned by our 3D optical scanner and a digital file is created.
	STEP 2 - DESIGN The CAD software allows our technicians to find margins, create occlusion, and determine contacts.
	STEP 3 - MILLING The CAD files are sent to a precision mill to shape the zirconia block into a full contour restoration.
	STEP 4 - MILLING After being milled and before being sintered, the zirconia is in a soft "green state".
	STEP 5 - SINTERING The restoration is then sintered for 12 hours and becomes virtually unbreakable.
	STEP 6 - STAINING The final restoration is stained and glazed to the prescribed shade.
