By putting IPS e.max ZirCAD Prime to the ultimate test we have shown that this material is ca- pable of great things.

The play of light and colour intensifies towards the incisal edge and produces a harmonious overall result, which allows the tooth to blend in smoothly with the natu- ral adjacent teeth.
