Zirconia


Full Contour Zirconia

At Mabel Dental Lab, we choose SageMax® by Ivoclar and Aidite for our zirconia restorations. As a trusted dental lab, we understand the need for consistent results across cases. These premium full-contour zirconia crowns are comparable, and in some respects superior, to BruxZir®, offering exceptional strength, natural-looking aesthetics, and remarkable versatility. They also feature the highest translucency levels among all zirconia we’ve tested.

The monolithic crown is milled from a single block, and so a zirconia crown can be up to five times stronger than a porcelain fused to metal (PFM) crown. It features a smooth surface, but is designed specifically for the posterior with an emphasis on strength. Our zirconia has received a 5-star rating from The Dental Advisor in a long-term clinical study. It also received the 2018 and 2019 Top Product award from The Dental Advisor in the Product Category of Long-Term Performer: Esthetic Zirconia. 

Preparation Requirements

Our zirconia crowns made from physical impressions require eight in-lab days, while digital cases require six in-lab days. Here are the specifics of the preparation process for zirconia crowns: 

  • Anterior full-coverage crowns require a chamfer with 1.5 mm facial reduction, 1.5 mm lingual contact clearance, 1.5 mm incisal reduction 1.25 mm reduction at the gingival margin with rounded internal line angles; or a shoulder with 1.0 mm lingual reduction, 2.0 mm incisal reduction, 1.5 mm labial reduction, 1.0 mm 360 degree rounded shoulder.

  • Posterior full-coverage crowns require a chamfer margin with 2.0 mm occlusal reduction, 1.5 mm buccal and lingual reduction with rounded internal line angles; or a shoulder with 2.0 mm occlusal reduction, 1.5 mm buccal and lingual reduction and 1.25 mm gingival margin reduction with rounded internal line angles.

  • Chamfer Margins – Correct preparation of the chamfer margins interproximally allows the appropriate bulk of porcelain.


Recommended Zirconia Cementation Information

When bonding a zirconia crown in the patient’s mouth, use the appropriate material based on your specific needs. Here are a few products to explore: 

  • Resin Ionomer cement (RelyX or RelyX Unicem, 3M ESPE)

  • Maxcem Elite (Kerr)
  • Panavia 21 or Panavia F 2.0 (Kuraray)
  • Glass ionomer cement (GC Fuji, GC America)


About Porcelain Fused to Zirconia (Layered Zirconia)

For anterior cases where aesthetics matter most, try our porcelain fused to zirconia (layered zirconia) crowns. They combine the durability of top-grade zirconia with the natural-looking translucency of e.max, providing the results that patients expect at a price point that meets your needs. Lab tests have shown that the fracture toughness and flexural strength of zirconia are significantly higher than those of alumina or any other all-ceramic restoration.

 


About Multi-Layered Zirconia


Our newest high-quality zirconia offering is a multi-layered zirconia by Aidite®, featuring exceptional aesthetics and strength. Made entirely from zirconia, the material features built-in layers that mimic the appearance of natural teeth. This option is suitable for applications where strength is a priority, reflecting our dental lab’s commitment to durable, natural-looking restorations.
