There is an old adage: “If it walks like a duck and quacks like a duck, it must a be a duck”. Although that might be true in some cases, it’s not true with MiYO but we understand why people are tempted to jump to that conclusion. This is primarily because the jar looks familiar, some of the colors look familiar and MiYO goes on in a thin layer, but that’s where the similarities end.
MiYO is a liquid ceramic, not a stain because its colors and effects are derived from pigments that are suspended in a unique self-glazing ceramic matrix with varying levels of translucency. MiYO’s kit design is much like a traditional layering ceramic system; yet achieves lifelike esthetics in a fraction of the thickness [0.1-0.2mm] that traditional layering ceramics require [1.0-1.5mm].
MiYO is different from a stain in that it lets light pass through it, exciting the light and maximizing the beauty of the substrate material underneath it. With MiYO you can add color and effects in a single, self-glazing firing, unlike traditional stain and glaze materials which are opaque and require more than one firing.
With the exception of Fissure (and all of the colors in MiYO Pink), all of the Colors and Structure materials in the MiYO Liquid Ceramic System are fluorescent.
Yes, although it’s preferred to have your MiYO Structure temperatures around 10°C lower just to be safe.
Yes, you can however keep in mind that you will be changing the refractive properties slightly.
This is one of the most important factors when firing MiYO due to the materials used to create MiYO’s unique viscosity. It is important to program your pre-dry time for around 4 minutes and your furnace entry time for around 6 minutes, depending on your furnace. Another critical factor is ensuring that the platform temperature is in between 200°C – 220°C.
Although every crown and scenario are different, a general rule of thumb is that MiYO Lumin will raise the value of a restoration roughly 1 shade per firing. So you can take an A2 to an A1 in one firing. We should mention that MiYO Lumin Plus is a new material which raises value even more than Lumin, as it will generally allow you to take a crown up 1-2 shades depending on the scenario.
The short answer is no, it’s not required but it is recommended, here’s why:
No. MiYO Structure differs from a traditional enamel material in that it is used in a much thinner application and is not used to create the depth associated with esthetics, but rather is used to create texture on the surface of full contour restorations, and to gently scatter light. The illusion of depth is uniquely achieved by adding color/contrast in the application of MiYO Color materials.
Yes, as with any ceramic material, the variations between furnace manufacturer and models necessitate dialing in proper firing temperatures for each furnace. Jensen is equipped to help get you in the general range depending on your furnace but always recommends taking steps to further dial in your specific programs in order to ensure consistent and highly esthetic MiYO crowns.

With the exception of Fissure all of the Colors and Structure materials in the MiYO Liquid Ceramic System self-glaze after firing.
