BruxZir® Anterior is the latest advancement in the BruxZir Solid Zirconia product line. This highly esthetic restorative material is designed specifically to satisfy the esthetic and functional requirements of the anterior region of the mouth. Exhibiting an average flexural strength of 650 MPa with translucency and color similar to natural dentition, BruxZir Anterior is an ideal, esthetic solution for your anterior cases. BruxZir® Anterior requires less reduction than monolithic glass ceramic restorations and does not create wear on the patient’s natural opposing dentition during occlusal and parafunctional activity.
Indicated for anterior crowns, bridges, inlays and onlays. An esthetic solution for bruxers and grinders when PFM metal occlusal/lingual or full-cast restorations are not desired or when patient lacks the preparation space for a PFM or has broken a PFM in the past. Zirconia can also be used for anterior teeth with a facial veneer of porcelain for improved esthetics
Shoulder preparation not needed, feather edge is OK. It is a conservative preparation similar to full-cast gold, so any preparation with at least 0.5 mm of occlusal space is accepted. A minimum occlusal reduction of 0.8 mm; 1.25 mm is ideal.
Try BruxZir crown in mouth and make any necessary adjustments to contacts and occlusion. Rinse internal surface of BruxZir crown with air and water, and place Ivoclean (Ivoclar) inside of restoration and rinse off after 20 seconds. Mix and place Ceramir cement in crown, seat crown on tooth and proceed with cleanup as it enters doughy stage.
Solid zirconia requires a cast gold type preparation.
Anteriors may have a facial veneer of porcelain but the occlusion will remain in 100 percent zirconia. Final Zirconia restorations are glazed to a smooth surface to reduce plaque accumulation.
Adjust 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 solid zirconia restorations with the porcelain polishing system of your choice.
