Clinical Indications

  • BruxZir® Solid Zirconia is indicated for crowns, bridges, screw-retained implant crowns and full-arch implant prostheses.
  • It is an alternative to PFM metal occlusal/lingual or full-cast restorations and ideal for restorations requiring extra durability such as crowns under partials or screw-retained implant crowns.
  • The chip proof durability of a BruxZir restoration is ideal for bruxers who have broken natural teeth or previous PFM restorations.
  • BruxZir Solid Zirconia is also ideal when the patient lacks the preparation space for a PFM.

Preparation Requirements

  • Feather edge is acceptable, although we recommend a chamfer.
  • .5 occlusal reduction is acceptable but preferably reduction of 1.5mm will produce superior results leading to improved strength, esthetics, and better occlusal planning to save you chairtime.

Adjustments

  • BruxZir restorations are made from solid zirconia, therefore, you may find them harder to adjust with conventional bur kits. There are several adjusting and polishing kits on the market for finishing and polishing BruxZir and solid zirconia products.
  • To easily adjust, polish or remove these restorations, Artistic Dental Laboratories suggests using fine diamond burs to reduce chipping and polishers to finish with a high polish shine.
  • Always use light pressure with water and air spray when adjusting ceramic restorations to avoid micro-fractures.
    • A football-shaped, fine diamond bur is most effective for adjusting occlusion on the occlusal surface of posterior teeth and lingual surfaces of anterior teeth.
    • A tapered, fine diamond bur is most effective for adjusting cusps or proximal contacts.
    • A round, fine diamond bur is used to adjust a cusp or fossa and for creating endodontic access.

    • For Finishing
    • Using light pressure, to avoid generating heat, and no water, begin polishing with the brown cup to remove abrasions left by the diamonds.
    • Continue pre-polishing with the green cup until the adjustment area has a glossy appearance.
    • Finally, use the white cup with light to medium pressure to achieve a "wet" high shine.

Cementation

When a fixed restoration is tried in the patient''s mouth it comes in contact with saliva. The phosphate groups in the saliva bind to zirconia oxide and cannot be rinsed out with water. The only way to successfully remove these phosphate groups from the interior of a fixed restoration is with the use of Ivoclean (Ivoclar Vivadent); or, lightly air abrade the inlay with 25 micron aluminum oxide (Al2O3).

  1. Try-in zirconia-based restoration, Make any necessary adjustments to contacts and occlusion.
  2. Rinse saliva out of restoration with water
  3. Place Ivoclean in restoration for 20 seconds, rinse and dry, or, lightly air abrade the inlay with 25 micron aluminum oxide (Al2O3).
  4. Apply primer and then cement with product of your choice

Cementing BruxZir restorations with resin-modified glass Ionomer (RMGI) cements, such as RelyX Luting Plus (3MESPE) and Fuji-CEM (GC America);

  1. Try-in zirconia-based restoration, Make any necessary adjustments to contacts and occlusion.
  2. Rinse saliva out of restoration with water
  3. Sandblast internal surface of BruxZir crown for 15 seconds, or place Ivoclean (Ivoclar) inside of restoration and rinse off after 20 seconds.
  4. Place zirconia primer, such as Z-Prime Plus (Bisco) or Monobond Plus (Ivoclar), on internal surface of BruxZir restoration and dry for 3 to 5 seconds with an air syringe.
  5. Mix and place RelyX Luting Plus or Fuji-CEM cement in crown, seat crown ontooth and proceed with cleanup.

Bonding BruxZir restorations with self-adhesive resin cements, such as RelyX, Unicem (3M ESPE) and Maxcem Elite (Kerr), self-etching resin cements such as Panavia F 2.0 (Kuraray) and MultiLink Automix (Ivoclar), or etch-and-rinse resin cements such as NX3 (Kerr) and Variolink 2 (Ivoclar):
  1. Try-in zirconia-based restoration, Make any necessary adjustments to contacts and occlusion.
  2. Rinse saliva out of restoration with water.
  3. Sandblast internal surface of BruxZir crown for 15 seconds, or place Ivoclean (Ivoclar) inside of restoration and rinse off after 20 seconds.
  4. Place zirconia primer, such as Z-Prime Plus (Bisco), TheraCem (Bisco), or Monobond Plus (Ivoclar), on internal surface of BruxZir restoration and dry for 3 to 5 seconds with an air syringe.
  5. Mix and place any of the resin cements above in crown, seat crown on tooth and proceed with cleanup.

Retentive preps= Resin reinforced glass ionomer (RelyX Luting Cement, 3M ESPE; GC Fuji Plus, GC America)

Non-retentive preps= Resin reinforced glass ionomer
(RelyX Luting Cement, 3M ESPE; GC Fuji Plus, GC America), a cleaning paste such as Ivoclean (Ivoclar Vivadent), and a zirconia primer such as Z-Prime Plus (BISCO)

Extremely Non-retentive preps= Resin cements(Ceramir, Doxa Dental Inc., RelyX Unicem, 3M ESPE; Panavia F2.0, Kuraray), a cleaning paste such as Ivoclean (Ivoclar Vivadent), and a zirconia primer such as Z-Prime Plus (BISCO)
