What kind of materials are used for Zirconia Crowns?

One of our flagship products at Keating Dental Arts is our KDZ Bruxer®, or zirconium crown. If someone indicates that they are going to order a zirconium crown, really what they are saying is that they are ordering zirconium dioxide. Zirconium Dioxide is a blend of heavy metal zirconium, from the periodic table with oxides. When they are mixed, they become a ceramic material. I’ve heard people say that zirconium dioxide is metal based. Well, it’s metal based before it becomes an oxide but by definition it is a non-metallic substance.

Zirconia Ceramic Transformational Toughening

The cool thing about this material is that it is very stable and very strong. In fact, the zirconium dioxide that we see with our KDZ Bruxer®, actually gets stronger as it gets stressed. It’s what we call transformational toughening, and as you apply pressure or force on the restorative material, the zirconium dioxide, you actually get increased cross-linking of the material. This cross-linking actually eliminates further propagation of fractures, which is why we seek traditional ceramics or ceramic on metal that won’t break under stress.

KDZ Bruxer Aesthetic® vs. KDZ Bruxer®

KDZ Bruxer® Advantages

The main difference in the KDZ Bruxer® is that it has a higher flexural strength, so with the KDZ Bruxer®, we have a flexural strength of about 1500 megapascals and flexural strength is how they measure ceramic materials. What they do is they take a bar of ceramic, they put it on 2 little sawhorses, they apply force until it breaks, and that’s the flexural strength. So theoretically, the higher the flexural strength, the more durable the ceramic. There is certainly going to be marginal ridges, central fossa, cuss tips, or any ceramic hanging off the prep, that’s undergoing stress on similar to what we would see with the flexural strength test.

KDZ Bruxer® Disadvantages

Now, the disadvantage of the KDZ Bruxer®, is it’s opaque, so aesthetics are compromised slightly. Certainly better than a porcelain piece of metal crown, or a gold crown, but it is a bit more opaque.

KDZ Bruxer Aesthetic® Advantages

We introduced the KDZ Bruxer Aesthetic®. This material is highly translucent, in fact, and it fits into a category called zirconium dioxide HT, or high translucent zirconium. There are several different brands on the market. We actually extensively test it, these materials and under blind studies we picked the material that we thought was the most aesthetic, in fact all the evaluators, and I was in that evaluation, picked the same material and that’s the material that we use for our KDZ Bruxer Aesthetic®.

Now, the advantage of KDZ Bruxer Aesthetic®, it is not opaque, in fact it is translucent and it rivals most of the alternative systems out there, including e.max, which is one of our most popular.

KDZ Bruxer Aesthetic® Disadvantages

The disadvantage, I’m not going to say a huge disadvantage, but the flexural strength is about 650 megapascals, or about half of what we see with our traditional KDZ Bruxer®. Still, this is 6 times stronger than a porcelain on a PFM and it’s a time and a half stronger than what we see with lithium disilicate being e.max, so it’s certainly not a weak material. It’s just not as durable as our traditional KDZ Bruxer®.

When to use KDZ Bruxer Aesthetic®

When do I use what? Second molars, or on patients I call destroyers, where they break everything, because they are not going to break a material that has a flexural strength of 1500 megapascals and we will use the same material as a core, or as a coping for multi-unit bridges. We can always layer ceramic on top of that, what we call the KDZ Ultra®, but this is what we use as our framework, because of the strength.

Where I use my KDZ Bruxer Aesthetic® is anywhere that I would use a lithium disilicate, when I want high aesthetics anterior, single crowns. We typically would not use it for veneers, we would stick to a more bond-able ceramic, like lithium disilicate, or empress. We will use this for crowns on premolars, again, part of the aesthetics, or even crowns on molars. I do a lot of my molars in KDZ Bruxer Aesthetic®, because I think it is more aesthetic than the traditional KDZ Bruxer® due to the translucency.

I also can use the KDZ Bruxer Aesthetic® for 3 unit bridges. Anterior bridges, let’s say I’m replacing a central, or premolar replacement, so let’s say I was missing my mandibular second premolar, I could do a KDZ Bruxer Aesthetic® bridge, very translucent, from molar to my first premolar, you got a 3 M bridge.

Final Conculsions

I hope that clears up and answers some questions about when would I use a KDZ Bruxer®, when would I use KDZ Bruxer Aesthetic®. They are 2 different materials, both very strong that have very different applications, not only in our lab, but in your clinical practice.

Clinical Performance of Zirconia Crowns

You know, with the popularity of monolithic zirconia, people are starting to ask, what is their clinical performance, they can look aesthetic, their high translucency, like our KDZ Bruxer Aesthetic®. They can look great, they fit unbelievable, very conservative, perhaps, in fact the occlusal we can have as thin as .5 millimeters, that’s a gold prep. Actually overall less than a millimeter, so very conservative.

What’s their clinical performance? Well, our traditional KDZ Bruxer® which we have now had available almost 10 years, had our very lowest remake and failure of any of the materials we offer, that includes gold, PFM’s, e. Max and empress. Now, what we found with our KDZ Bruxer Aesthetic®, which we’ve had almost a year now, is very similar clinical performance that we see with our traditional KDZ Bruxer®.

Durability and Strength

When someone says, is this durable, is this something that is predictable and one that I can rely on for my patients? I would say absolutely yes. The flexural strength of a KDZ Bruxer® is about 1500 megapascals. The KDZ Bruxer Aesthetic® is about 650, even though that’s only half, you look at a material like empress, which has great clinical performance, it’s flexural strength is only 200, 1/3 of that of our KDZ Bruxer Aesthetic®, a 1/7 of that of our KDZ Bruxer®. E. Max is about 400, so 400 megapascal flexural strength is less than 60% what we see with our KDZ Bruxer Aesthetic® and less than 30% of what we see with our KDZ Bruxer®.

Final Conclusions

My philosophy as an educator as a clinician, when I see my own patients, when I want a material that’s durable, that’s going to perform excellent, I think the KDZ Bruxer® and the KDZ Bruxer Aesthetic® are great options to traditional dentistry like a porcelain metal crown and in gold that offers some compromises.

Why its important to take a proper prep shade and any other info

Often times I’m asked by a clinician, why do I need to take a preparation shade, when I’m placing a KDZ Bruxer Aesthetic®? Well, what they are thinking about it our original KDZ Bruxer® or other monolithic zirconium dioxides, that are very opaque.

Advantages of Opaque Zirconium for Ceramic Crowns

One of the advantages of our more opaque zirconium is if you have a dark spot, it will block it out. If you have an amalgam core, or a gold core, a blue buildup. It will block that out, the problem is it compromises aesthetics. Our KDZ Bruxer Aesthetic®, because of its translucency, which will improve the esthetic value, is that it won’t allow the prep to shine through, which is what we want. We’ve have always wanted that from our all ceramic restorations. We want to see depth, we want to see dent shining through that ceramic.

Preparation Shade

The KDZ Bruxer Aesthetic® being translucent, but still strong, allows that preparation to shine through. Now when we fabricate, design and fabricate the KDZ Bruxer Aesthetic® here at Keating Dental Arts, we have options regarding color and translucency, as we fabricate it. What we need to know is, what shade is your preparation? If we know the shade of your preparation, then we can choose the correct and corresponding opacity of the KDZ Bruxer Aesthetic® to optimize aesthetics, if we have a nice prep shade, or to dilute or inhibit some of that darker prep shade shining through.
