1. briefly steamed off or cleaned with water and a soft toothbrush Drying before sintering In the case of high humidity In an environment with a high level of humidity the restorations can absorb moisture after drying For this reason sintering must take place within a maximum of one hour after drying To avoid damage during sintering the restoration must be dried in the drying cabinet e 30 minutes at 80 C 176 F or e 10 minutes at 150 C 302 F NOTICE Risk of damaging the restoration Drying at temperatures above 150 C 302 F can damage the restoration All restorations to be sintered must be dried thoroughly first especially for super speed sintering Any residual moisture can cause the parts to burst 65 41 374 D3487 8 D3487 201 09 02 23 12 2014 65 41 374 D3487 D3487 201 09 02 23 12 2014 Sintering Restorations made from inCoris TZI C have to be sintered in dry conditions The sintering process should only be performed in Sirona inFire HTC inFire HTC speed with the pre programmed inCoris ZI and inCoris TZI programs As an alternative the sintering process can be carried out in the compatible VITA Zyrcomat or Ivoclar Vivadent Sintramat high temperature furnace In any case the details in the manuals for the respective furnaces are to be adhered to The classic program for sintering with inCoris TZI C is the same as for inCoris TZI and inCoris ZI The sintering result from furnaces oth2. materials Sirona Dental Systems GmbH Translucent pre dyed zirconia ceramic blocks for inLab and CEREC Recommended tools and materials e Modeling wax Scan wax Sirona Suitable for scans with the inLab scanner not for exposures with inEos e Wet grinding turbines KaVo K AIR plus KaVo IMAGO Steco System Technik GmbH amp Co KG NSK Presto Aqua Girrbach Turbo Jet Acurata e Grinding tools for reworking with the wet grinding turbine with handpiece Diamond grinding element sets Ceramic Line Telescope Line Sirius Dental Innovations Diamond porcelain polisher for handpiece green orange Hager amp Meisinger Art No HP 803 104 372 533 170 Diamond polisher for handpiece green and orange EVE Diacera e Other Suitable colored contact materials e Preparation sets Preparation set acc to K pper Hager amp Meisinger Art No 2560 Preparation set acc to Baltzer and Kaufmann Hager amp Meisinger Art No 2531 65 41 374 D3487 12 D3487 201 09 02 23 12 2014 Sirona Dental Systems GmbH 8 Fastening instructions Translucent pre dyed zirconia ceramic blocks for inLab and CEREC Fastening instructions Restorations made from inCoris TZI C can be fastened non adhesively with glasionomer or zinc phosphate cements or adhesively with the self curing PANAVIA 21 TC composite or the dual curing PANAVIA F composite Kuraray Both products contain the spec
