The history of zirconia dental crowns

Zirconia has risen to popularity in dentistry since the early 2000’s. What started as creating metal-free copings has turned into more dentists opting for zirconia over traditional porcelain-fused-to-metal or full gold crowns. As a zirconia dental lab, our zirconia crowns and bridges are renowned for their exceptional strength due to the unique properties of zirconia, a ceramic material known for its high resistance to fracture and wear, making it an ideal choice for dentists.

Zirconia material performance

Yttria stabilized zirconia or ysz refers to yttrium oxide, a heavy white powder, that can be added to zirconia to make it more translucent. The higher the yttria in a zirconia crown, the more aesthetic the zirconia dental crown will be.

What does it mean?
What does it mean?
Yttria is an oxide. The more Yttria added. The more translucent and aesthetic the Zirconia becomes.
What does it mean?
The higher the flexural strength measurement, the stronger the material.

What it looks like?
500MPa-1400MPa
Relationship
Relationship
As more yttria is added to improve aesthetics (3Y versus 4Y–5Y), the strength and fracture toughness decrease.
Relationship
The highest strength Zirconia is 3Y. The lowest strength, most aesthetic is 5Y.

When to prescribe zirconia crowns

What we appreciate about zirconia, as a zirconia dental lab, is its versatility in strength and aesthetics when compared to other dental crown materials such as PFM and eMax. Not only can you achieve comparable aesthetics for anterior teeth with zirconia as you can with eMax, zirconia crowns are more durable and less prone to breaking.

Zirconia dental crown FAQ

What is the best prep style for zirconia crowns?

It is best practice to give approximately 0.5mm of space when prepping for posterior crowns. The proper occlusal reduction is between 1 and 1.5mm or 1.5 to 2mm. Using a shoulder or chamfer margin style, provide for a 0.5m reduction at the gingival margin. 

For anterior zirconia dental crowns, you’ll need to leave at least 0.3 mm of space to accommodate the crown’s wall thickness. Additionally, you’ll need to account for an incisal reduction of either 1 to 1.5 mm or 1.8 to 2.0 mm. At the gingival margin, you’ll need a reduction of at least 0.5mm.

What retraction style works best for zirconia crowns?

Double cord is the best option for retraction due to the increased accessibility and improved displacement of tissue. Pack two knitted cords (soaked in a hemostatic material and at different diameters) and leave the larger cord in place for at least five minutes before pulling and scanning for optimal results.

 

Digital scans benefit most from adequate tissue retraction when using zirconia crowns and in the event of a poor scan identified chairside, minimal effort is required to re-scan for optimal results.

Does polishing zirconia differ from polishing porcelain?

Yes, polishing zirconia differs from polishing porcelain because the two materials have a different hardness scale. The polishing agents you use will have different abrasive materials in the polishing paste. You can use polishing paste for porcelain with zirconia but you’ll be working four times harder. To polish zirconia, do it under irrigation first and foremost, so that you can add micro fracturing to the restoration. There are a lot of polishing materials available on the market, some specifically made for specific materials so make sure to look for one made for the restorative material you’re using.

What is the downside of zirconia crowns?

There aren’t many downsides of zirconia crowns. At times when there is not enough occlusal space, zirconia may not be the best option. In the past, it could be difficult to match zirconia crowns to the color of adjacent teeth and there could be potential damage to neighboring teeth – but with digital dentistry advancements like  intraoral scanning and CAD/CAM design, shade matching workflows ensure the zirconia dental crowns are the perfect shade and digital dental designs place special emphasis on proper spacing and alignment of zirconia crowns.
