Zirconia is becoming more and more popular in the dental industry. There are so many zirconia disk brands on the market. And it is obvious that zirconia disks have differences in strength, translucency, sintering temperature, density etc. How come? While there are several factors that make disks very different:
Purity/contamination – If a disc is made in an unclean environment you won’t be able to see it until the restoration is made.
Flexural Strength – If the density of the zirconia disc isn’t uniform, it’s going to affect the final physical properties.
Density/shrinkage uniformity – If the disc doesn’t have a uniform density then when it is fired the restorations may warp.
Thickness uniformity – Though this is not very common, if for some reason the disc does not have a uniform thickness then you risk breaking your cutting tools during the milling process.
Milling properties – If zirconia discs are underfired they may be too soft. If the discs are overfired they may be too brittle. This can affect cutting speed and may cause chipping.
Color and translucency – If the discs are not pre-sintered correctly & consistently then some of the coloring you do in the green state may be lost. A disc that is too dense won’t keep the color and may not offer enough chroma (saturation).
