Zircon crown
Situational model
Tooth 23 is going to be restored by zircon crown
Creating of zircon framework
InLab program
Zircon block
The process of milling
Milling
Regeneration firing
Zircone building
For building of the crown was used Ivoclar vivadent IPS e.max systém
Zir Liner
Creates connection between framework and e.max mass
ZirLiner ( powder+ liquid) has to
be applied over whole surface
by protracted movements
Firing - 960°C for 1 min
Building of the crown
Building starts with aplying of Dentin. The mass is applied by special brush for
ceramics
Firing - 750°C for 1 min
Building of the crown
Building of the crown continues with applying of Transpa inscisal
The crown is builded into approximate shape of tooth
