Zircone building
For building of the crown was used Ivoclar vivadent IPS e.max systém
![Page 10: Zircon crown. Situational model Tooth 23 is going to be restored by zircon crown](https://reader034.vdocuments.site/reader034/viewer/2022050820/56649c7f5503460f949352c0/html5/thumbnails/10.jpg)
Zir Liner
Creates connection between framework and e.max mass
ZirLiner ( powder+ liquid) has to
be applied over whole surface
by protracted movements

Building of the crown
Building starts with aplying of Dentin. The mass is applied by special brush for
ceramics

Building of the crown
Building of the crown continues with applying of Transpa inscisal
The crown is builded into approximate shape of tooth
