Full-Contour Zirconia

Full-Contour Zirconia

Our skilled technicians mill our full-contour zirconia using our inLab MC X5 mill. These restorations offer the highest flexural strength of any ceramic restoration, but are still gentle enough to protect bruxers’ opposing dentition. We are able to fabricate full-contour inlays, onlays, crowns, multi-unit bridges, and full roundhouses.

Anterior Zirconia

CEREC® Seminars Laboratory is your resource for highly esthetic full-contour anterior zirconia restorations. With a flexural strength of up to 550 MPa, this material provides excellent durability. Your patients will be extremely satisfied with the beautiful results afforded by this anterior zirconia. It offers enamel-like translucency with chromatic and translucent multi-layer. This product is available in 16 specifically developed natural shades.

Posterior Zirconia

When cases require extreme strength, our posterior full-contour zirconia restorations will fulfill every requirement. With a flexural strength of 1200 MPa, this material is ideal for the posterior region. It also has 41% translucency and can match all 16 VITA® Classic shades, which ensures an esthetic result. Our posterior zirconia is an ideal alternative to PFMs. It is gentle on opposing dentition to be an excellent option for patients suffering from bruxism or clenching.


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.

Solid zirconia requires a cast gold type preparation. If adjustments are needed, use zirconia specific diamonds and rubber wheels polishing with diamond paste.
