What is BruxZir Solid Zirconia?
BruxZir® Solid Zirconia is a monolithic zirconia crown, bridge, screw-retained implant crown, inlay or onlay with no porcelain overlay. First launched as being "More Brawn Than Beauty," the material was originally intended to provide a durable, more esthetic alternative to posterior metal occlusal PFMs or cast gold restorations for demanding situations like bruxers, implant restorations and areas with limited occlusal space. Now, thanks to the new BruxZir™ Shaded formulation, BruxZir restorations exhibit improved translucency and color similar to natural dentition, making them a restorative option in the anterior as well. Complete color penetration all the way through the restorations ensures greater shade consistency and prevents any shade changes after occlusal adjustment.
Designed and milled using CAD/CAM technology, BruxZir Solid Zirconia is sintered for 2.0 hours at 1,530 degrees Celsius to achieve optimum strength. The final BruxZir crown or bridge is then glazed to a smooth surface. BruxZir Solid Zirconia crowns & bridges are backed by Glidewell Dental Lab's seven-year free replacement warranty.
BruxZir is the fastest-growing product in company history, with dozens of dental labs across the U.S. clamoring to become an Authorized BruxZir Lab. The unique composition of BruxZir Solid Zirconia has garnered accolades from dental zirconia supplier Tosoh Corporation and the Pride Institute, and The Dental Advisor named BruxZir Solid Zirconia a Top Long Term Performer in 2013.
BruxZir Solid Zirconia is indicated for crowns, bridges, implants, inlays and onlays. It is an esthetic alternative to PFM metal occlusal/lingual or full-cast restorations. The chip proof durability of BruxZir is ideal for bruxers who have broken natural teeth or previous PFM restorations. BruxZir is also ideal when the patient lacks the preparation space for a PFM.
- Chip-resistant, as it is made of solid zirconia with no porcelain overlay
- Glazed to a smooth surface to reduce plaque accumulation
Now Available for Full-Arch Indications
The BruxZir® Solid Zirconia Full-Arch Implant Prosthesis combines the function and stability of a fixed denture with the strength and esthetics of monolithic zirconia. Constructed from 100% BruxZir Solid Zirconia, this full-arch prosthesis attaches to implants via titanium connections. Strong, hygienic and affordably priced, this fully edentulous restoration offers exceptional resistance to the chips, fractures and stains that can compromise acrylic dentures.
Preparation Requirements for BruxZir Crowns & Bridges
Shoulder preparation not needed, feather edge is okay. It is a conservative preparation similar to full-cast gold, so any preparation with at least 0.5 mm of occlusal space is accepted.
- Minimum occlusal reduction of 0.5 mm; 1 mm is ideal.
Instructions for Adjusting and Polishing BruxZir Crowns & Bridges
Technical Update: Download Instructions
- Adjust BruxZir Solid Zirconia restorations using a fine-grit diamond with light pressure to avoid potential microfractures. The specially designed Axis Dental BruxZir Adjustment & Polishing Set (LS-7579) may be purchased through your dental dealer or by calling 800-355-5063.
- A football-shaped bur is most effective for adjusting the occlusal surfaces of posterior teeth and lingual surfaces of anterior teeth.
- A tapered bur is most effective for adjusting proximal contacts.
- A round bur is used to adjust a cusp or fossa and for creating endodontic access.
Technical Update: Do Not Use Discs To Finish Full-Contour Zirconia
- Ceramir® Crown & Bridge (Doxa Dental; Newport Beach, Calif.) or a resin-reinforced glass ionomer cement such as RelyX™ Luting Cement (3M ESPE; St. Paul, Minn.) or GC Fuji Plus™ (GC America; Alsip; Ill.)
- For short or over-tapered preparations, use a resin cement such as RelyX™ Unicem (3M ESPE) or Panavia™ F2.0 (Kuraray; New York, N.Y.)
Instructions for Seating BruxZir® and Other Zirconia-Based Crowns & Bridges
BruxZir restorations are fabricated from solid zirconia oxide material, much like the zirconia oxide coping found in restorations such as Prismatik Clinical Zirconia™, Lava™ Zirconia (3M ESPE; St. Paul, Minn.), and NobelProcera™ (Nobel Biocare; Yorba Linda, Calif.). Like most metals, zirconia exhibits a strong affinity for phosphate groups, and zirconia oxide is no different. We can take advantage of this fact with phosphate-containing primers, such as Monobond Plus (Ivoclar Vivadent; Amherst, N.Y.) and Z-Prime™ Plus (Bisco; Schaumburg, Ill.), or cements such as Ceramir® Crown & Bridge (Doxa Dental; Newport Beach, Calif.). Unfortunately, saliva also contains phosphates in the form of phospholipids, so when a BruxZir crown or bridge is tried in the patient's mouth and comes in contact with saliva, the phosphate groups in the saliva bind to the zirconia oxide and cannot be rinsed out with water. Attempting to use phosphoric acid (which is full of phosphate groups) to "clean" the saliva out only makes the problem worse.
The only way we have found to successfully remove these phosphate groups from the interior of a BruxZir restoration is with the use of Ivoclean (Ivoclar Vivadent). This is a zirconia oxide solution placed inside the restoration for 20 seconds and then rinsed out. Due to the large concentration of free zirconia oxide in the Ivoclean, it acts as a sponge and binds to the phosphate groups that were previously bound to the BruxZir restoration. Once the Ivoclean is rinsed out, you will have a fresh bonding surface for the Monobond Plus, Z-Prime Plus or Ceramir to bond to.
The protocol would be:
Technical Update: Download Instructions
- Try in BruxZir or zirconia-based restoration.
- Rinse saliva out of restoration.
- Place Ivoclean in restoration for 20 seconds and rinse.
- Cement restoration with Ceramir –or– place Monobond Plus/Z-Prime Plus and place with cement of your choice.
