With today’s patient requesting metal free restorations, clinicians are choosing zirconia over conventional PFMs (Porcelain Fused to Metal) or full-gold crowns due to their superior strength, durability, and excellent aesthetics.
Layered vs Solid Zirconia
Layered zirconia is more translucent and opalescent, but unlike solid zirconia, it is especially suitable for anterior crowns. Although generally used for anterior crowns, layered zirconia may also be used for posterior crowns if there is sufficient clearance. When done skillfully, the very best aesthetic results can be achieved. With traditional PFM’s there will be a opaque reflection of light while layered zirconia crowns will have more transparent reflection of light to create more natural looking aesthetics.
Advantages of Choosing Zirconia Crowns
- Zirconia is suitable for patients with metal allergies or who would prefer to have metal-free restorations.
- Zirconia is metal-free, which prevents darkening around the gingival area. This eliminates the possibility of metal margins becoming exposed due to gum recession.
- Zirconia crowns can be conventionally cemented in place by using Rely-X Unicem 2, then applying the bonding agent of choice to prep.
- Using Inlab CAD/CAM design and manufacturing processes provide patients with a precise fit, reducing the chair-side time required for adjusting and cementing these restorations.
