5PCS Cerec CAD Lithium Disilicate Glass-Ceramic Blocks Sirona System In Dental Lab CEREC CAD CAM Blocks

Composition:

Mass percentage: SiO2 (70±5)%；Li2O (15±5)%；K2O (4±2)%；Al2O3 (5±3)%；P2O5(5±3)%；ZrO2 (8±3)%；Other Oxides(0-5)%

Note: specifications with rectangular shape can only be processed by CAD/CAM system

Indicationsveneers, inlays, onlays, single anterior and molar restorations processed by CAD/CAM system

BAOT supplies classic shades of lithium disilicate glass ceramics, its strength close to the human natural teeth. Good machinability and high transparency make it suitable for CAD/CAM design and can be used for the crown, veneer, onlay, inlay, etc. to meet the needs of aesthetic restoration.

FIRING PARAMETERS & BASIC OPERATION

-Standard-

① Steps

Color comparison → impression → CAD design → grinding for 15~35 minutes (due to the specification difference of the restoration) → glazing or enamel → sintering → inspection → bonding

② Sintering procedure（Take the E.MAX P310 porcelain casting furnace as an example. Different sintering furnaces have temperature deviations and need to be fine-tuned according to the actual situation.）

The processing takes about 25 minutes：

③Start at 450°C, put in the restoration to be sintered, last for 2 minutes, heat up at a rate of 30°C/min, the temperature rise time is about 12minutes (750 seconds), heat up to 850°C and hold for 7minutes (420seconds), then open The cover is directly cooled by air.

▲Can be used or not used Object Fix Flow. If you use Object Fix, please select IPS Object Fix Flow.

④ If you need to glaze a second time, the corresponding glazing procedure：Start at 450°C, put the restoration to be glazed, dry time 2 minutes, heating rate 50°C/min, heating time 7minutes (420seconds), heating to 800°C for 2 minutes (120 seconds), and then directly Adopt air cooling.

Special Note：

There may be a shrinkage rate of no more than 0.2% during the sintering process, which must be fully considered in the design software.

If the glazing and sintering steps are combined, use the procedure ③ to operate. If the sintering and glazing are used in a step-by-step manner, use the procedure ③ for sintering first, and then use the procedure ④ for glazing.
