We mill all our zirconia in-house. Having complete control of the process from end to end means we can set the standard and provide the highest quality zirconia restorations while maintaining the customization of design desired by our dentists. With esthetics that mimic natural teeth you can provide your patients with a monolithic metal free restoration economically.
- Unparalleled Translucency
- High Strength and Durability
- Suitable for anterior or posterior bridges Up to 3 Units
- 100% Digitally manufactured in lab
- Conventional cementation Zirconia
Milled in our laboratory to full contour and stained to your specifications
Full-contour zirconia is so versatile, it can be used in almost any situation from singles, bridges with any combination of abutments and pontics, inlay bridges and screw-retained implants. Also an esthetic alternative to a PFM with metal occlusion due to limited space.
When esthetic expectations are high and it is important that the restorations match surrounding natural dentition or other existing restorations. If bonding is necessary to retain the restoration, bond strength is weaker and less predictable than other ceramics.
Shoulder preparation not needed. A mild chamfer or a feather-edge margin is good. 1mm buccal, lingual, and occlusal reduction is ideal, but can go to .5mm in some areas when reduction is limited. Minimum occlusal reduction of 0.5 mm; 1 mm is ideal. Adjustments and polishing: Adjust full-contour zirconia crowns and bridges using water and air spray to keep the restoration cool and to avoid microfractures 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 full-contour zirconia restorations with the porcelain polishing system of your choice.
It is recommended that full-contour zirconia be cemented using a zirconia primer like Z-Prime from Bisco or Clearfil Ceramic Primer from Kuraray. Alternatively, a resin reinforced glass ionomer such as RelyX Luting cement can also be used. When a greater bond is needed due to the lack of a retentive preparation, use a resin cement like RelyX Unicam or RelyX Ultimate. Before cementing all full-contour zirconia crowns, the interior surface of the crown needs to be cleaned with Ivoclean (Ivoclar Vivadent – Amherst, NY). This is critical in assuring maximum bond strength.
Veneered porcelain over our in lab milled zirconia substructure for the most translucent effect and highest aesthetic results.
A CAD/CAM substitute for traditional PFM, our porcelain-fused-to-zirconia can be used for anterior and posterior crowns, crowns over implants, and bridges of up to fourteen units.
- Attachment cases
- Cases with less than 1 mm clearance
- Patients who have broken a PFM crown
- Cases that require bonding
The ideal preparation for PFZs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required.
- Resin Ionomer cement (RelyX or RelyX Unicem, 3M ESPE)
- Maxcem Elite (Kerr)
- Panavia F 2.0 (Kuraray) – ideal for short, tapered preparations
- Glass ionomer cement (GC Fuji, GC America)
