What Zirconia Block Properties Prevent Chipping?

 Zirconia is one of the most popular materials in dentistry which helps in manufacturing tough and long lasting dental restorations. These blocks are highly chip resistant, which is a problem often found with other materials. But what is it about zirconia blocks that make them so resistant to chipping? Now that we know the characteristics of zirconia blocks that limit chipping.

​

What’s known about how zirconia blocks stand up to the forces applied during chewing of a type that might induce chipping.

Zirconia blocks are constructed out of zirconium dioxide, a durable and extremely strong material. What this means is that zirconia milling machine can hold up against biting/chewing forces that result in chipping of the prosthesis. Materials such as porcelain, that might easily chip, are less likely to when using zirconia blocks.

Toughness for chip resistance of zirconia-based ceramics.

Toughness is a materials property that is a measure of its resistance to cracks and fractures. zirconia milling are very tough materials, they do not break under an impact or when it is bent. It is this property that is invaluable in protecting zirconia blocks from chipping, ensuring their shape and strength is preserved when put under strain.

How does this property lend itself towards chip resistance.

The strength of zirconia blocks is an important determinant of its chip resistance. When the dental cad cam machine is submitted to the force that can cause the chipping, because of its high toughness, the energy to destroy the structure is absorbed and the force is distributed uniformly in the material. This minimizes the risk of ruptures and fractures, preserving the integrity and function of the zirconia block.

Why certain zirconia blocks are more prone to chipping.

Zirconia block formulations can differ from one manufacturer to another, or depending on the needs of the dental restoration. Such compositions might include additives or alterations designed to add chip resistance to the zirconia block. These formulations are intended to maximize the properties of the material and reduce the likelihood of chipping.

A smooth finish can minimize the possibility of chipping zirconia blocks.

Not only do zirconia blocks have the advantages of strength and toughness in themselves but also are capable of super smooth surface treatment. Smoothness of the surface prevents possible stress concentrators - and hence chipping. A smooth finish on the zirconia block reduces the damage and chipping by removing rough uneven patches on the block.

In summary, zirconia blocks are chipping resistant because of their strength, toughness, composition and surface finishing. And these are properties that combine to make zirconia blocks able to resist the forces that chip other materials.
