Vsmile HappyZir Zirconia Disc Family ( Products Introduction & Selection Guide )


Vsmile HappyZir Zirconia Disc Family ( Products Introduction & Selection Guide )

Today, there are three primary categories of zirconia discs in Vsmile HappyZir Zirconia family, each with different flexural strengths:

Framework materials(HT): 1350 MPa

High translucency (ST SHT) for full contour bridges: 1100-1200 MPa 

Ultra translucent (UT) for Anterior single units and 3 unit bridges: 700 MPa

3D Multi-colored & multi-translucency

The HT highest strength materials are for frameworks and used for hybrid implant custom abutments,its kind of our first generation zirocnia ,only white color is available . And ST and UT have been designed as monolithic materials and layered zirconia material .

Within ST and UT category , there are now three subcategories of materials:

White (with and without matching green state coloring systems)

Pre-shaded, 16 different pre-shades

Multi-shaded, 16 different pre-shades

Pre-shaded Discs

Vsmile Pre-shaded zirconia discs are made by adding small percentages of yellow, pink, gray powders to white powder prior to pressing.


Consistent shade match

Lower labor as no green state shading is needed

Shade consistency throughout the full depth of the restoration


Increased disc inventory

Monochromatic restorations

Depending on the system, increased surface stains needed


Multi Layered Discs

As the next generation of the zirconia evolution, Vsmile Multi Layered zirconia pucks are made having different color formulas through the disc. For instance, the bottom 1/3 of the disc could be shade A3, the middle A2, and the top 1/3 white with some gray added. Vsmile Multi layered zirconia discs are currently readily available in 20different shade systems(Vita 16shades + 4 Bleach Shades)

One consideration that can be problematic: positioning the STL file in the disc during CAM operation. This material may not be a good choice for 4 axial mills as the positioning of the units should not be based on path of insertion, but rather the distribution of colors as it relates to the crown.


Reduces manufacturing cycle

Superior esthetics

Enables competitive advantage


Must use 5 axis mill

Care must be taken when placing STL files in the virtual disc so color placement is correct.

Latest Option: 3D Multi-Translucent

Vsmile 3D Zirconia Disc offers a combination of multi translucencies and colors. These discs will be most opacious and more chromatic in the bottom or cervical part of the disc, while the middle will be less opaque and lower in chroma and have less strength (1050 MPa), and the top of the disc will be 14% more translucent than the cervical with a flexural strength of 700 MPa.

This type of disc has several different layers with a blended zone between each. In addition to translucency transitions, there are shade transitions as well. To date, this disc will provide the most life-like restorations possible for restoration.


No green state coloring needed

A disc and crown with both color and translucency gradations

Likely the most esthetic material available


Crown must be positioned or rotated during CAM correctly in the disc for correct color placements.

Increased inventory

Increased disc cost

Selecting the right zirconia for your production will remain lab- specific. Offering and milling from multiple zirconia categories is now nearly essential to compete and thrive.
