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

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
