1 Zircon crown

2 Situational model

3  Tooth 23 is going to be restored by zircon crown

4 Creating of zircon framework

5 InLab program Zircon block

6 The process of milling

7 Milling

8 Regeneration firing

9 Zircone building  For building of the crown was used Ivoclar vivadent IPS e.max systém

10 Zir Liner  Creates connection between framework and e.max mass  ZirLiner ( powder+ liquid) has to be applied over whole surface by protracted movements

11

12  Firing - 960°C for 1 min

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

14  Firing - 750°C for 1 min

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

16 The crown after second firing

17 Machining Process of machining  Neck  Contact  Height ( articulation)  Morfology  Surface texture

18 Glaze  For glazing of the crown was used IPS Empress

19

20  Firing - 725° for 1min 30 sec
