Verotek™ Aesthetic

Verotek™ Aesthetic represents a revolutionary advancement in solid zirconia material for anterior and posterior restorations. You can provide your patients with a restoration that compares to e.max in aesthetics, with nearly twice the strength!  Verotek™ Aesthetic is a full-contour solid zirconia crown or bridge restoration with no porcelain overlay. It is glazed with a smooth wear-kind surface optimized for use in the aesthetic zone with natural translucency and internal color. Verotek™ Aesthetic crowns are precision-milled and sintered for 12 hours at 1450⁰ C for a homogenous structure that is significantly stronger than lithium disilicate.
 

Verotek™ Aesthetic Advantages

• Improved translucency and intrinsic color as compared to BruxZir^® zirconia
• Available for single units and 3-unit bridges including molar abutment
• Flexural strength of 780 MPa – almost twice the strength of e.max
• Biocompatible medical-grade zirconia
• Monolithic structure makes the restoration nearly chip-proof
• Fabricated using CAD/CAM technology for precision fit and marginal accuracy

Cementing recommendations

• Resin-reinforced glass ionomer cement: RelyX (3M ESPE), Fuji Plus (GC America)
• Resin cements for short or over-tapered preparations: Unicem (3M ESPE)
• Ceramir C & B (Doxa)

Prep requirements

• Slight chamfer margin preferred for best result
• A more conservative preparation than is required for e.max
• 1.5-mm of occlusal space is ideal

Seating recommendations

Research has shown that saliva contamination can inhibit the bond of solid zirconia and zirconia oxide copings. To successfully remove saliva, it is suggested that after try-in and before priming, the crown should be cleaned with Ivoclean, a zirconia oxide solution from Ivoclar-Vivadent.
The suggested protocol is:

1. Try the Verotek™ Aesthetic restoration in the patient’s mouth;
2. Rinse saliva out of the restoration with water;
3. Place Ivoclean in restoration for 20 seconds, rinse and dry;
4. Apply primer and then cement with product of your choice.

Verotek™ FCZ

Verotek™ FCZ (full-contour zirconia) is a new option for posterior restorations. With these virtually unbreakable all-ceramic crowns, you can provide your patients with the strength to withstand severe para-functional activity while avoiding metal-based restorations.

• Metal free alternative to PFM’s
• Predictable price - No volatile gold costs.
• Large span bridges available
• Conventional cementation. Use your favorite cement.
• Zirconia strength:
  • 2x stronger than alumina ceramics
  • 5x stronger than conventional glass ceramics
  • Strength of a PFM
• Aesthetics of an all ceramic:
  • Natural translucency
  • No black oxidation lines or gingival graying

Contraindications

• Beveled, feathered or knife-edge margins
• Tight inter-occlusal space where core may be exposed

Prep requirements

• 2mm occlusal clearance
• 1mm deep, 360 degree chamfer margin

BruxZir®

Indications

• Ideal for bruxers and grinders who have destroyed other restorations
• Posterior restorations
• An esthetic alternative to posterior PFMs with metal occlusals and full-cast crowns

Contraindications

• Not desirable for anterior esthetics

Preparation

• Any margin preparation acceptable; slight chamfer preferred
• Conservative preparation similar to a full cast gold
• 1.0mm of occlusal space is ideal, however a prep with at least 0.75mm is acceptable

Adjusting and Polishing

• Use a fine grit diamond with copious amounts of water and air spray to keep the restoration cool and to avoid micro-fractures.
• Always polish post-adjustment with porcelain polishing system
  Recommended: Axis BruxZir® Adjustment and Polishing Set LS-7579 available from your dealer

Cementation Recommendations

• Ceramir® Crown & Bridge or a resin-reinforced glass ionomer cement such as RelyX™ Luting Cement or GC Fuji Plus™
• To increase retention on short, tapered preparations, remove saliva contamination with Ivoclean paste (Ivoclar Vivadent) and use self adhesive resin cements such as RelyX Unicem (3M Espe) or SpeedCEM (Ivoclar Vivadent)

Removing a BruxZir® Crown

• Recent research by Clinical Research Associates (CRA) indicates that bur performance was based more on brand than on grit or shape. The top performing burs were: Premier Two Striper [770.8Z, 770.8C, 770.8F], Midwest Diamonds [856 Fine/Coarse]. For a cost -effective option, try: Microcopy NeoDiamond [1116.8C, 1116.8F] (CRA July, 2012)
• Use plenty of water. Apply firm pressure in repeated, short, on-off sequence.
• Cut through the crown facial to lingual and use crown spreader. Pieces normally come off in large chunks.
