TECHNICAL NOTES
BruxZir Solid Zirconia requires a cast gold type preparation. Chip-resistant, as it is a monolithic zirconia material with no porcelain overlay. Anteriors may have a facial veneer of porcelain but the occlusion will remain in 100 percent zirconia. Final BruxZir restorations are glazed to a smooth surface to reduce plaque accumulation.
Adjust BruxZir zirconia crowns and bridges using water and air spray to keep the restoration cool and to avoid micro-fractures with a fine grit diamond. If using air only, use the lightest touch possible when making adjustments. A football shaped bur is the most effective for occlusal and lingual surfaces (on anterior teeth); a tapered bur is the ideal choice for buccal and lingual surfaces.
Polish BruxZir Solid Zirconia restorations with the porcelain polishing system of your choice. Or, purchase the Axis Dental BruxZir Adjustment & Polishing Set (LS-7579) through your dental dealer or by calling 800-355-5063.
- Begin by pre-polishing using light pressure and no water with the green polishing cup. This will remove abrasions left by the diamonds during adjustment. The green cup may also be used alone for minor adjustments.
- Use the blue cup to create the initial high shine. Using light to medium pressure and enough water to create a slurry, you will see the glossy look reappear on the restoration.
- Finally, use the yellow cup at medium to light pressure to achieve a "wet" shine. The edge of the cup may also be used to polish the marginal ridges of the BruxZir Solid Zirconia restoration.
BruxZir is made from translucent Prismatik Clinical Zirconia™.
