Sirona Dental Cerec Block In Lithium Disilicate
It is a glass-ceramic material applied to the chairside processing system.The lithium disilicate cad cam blocks are applied at the dental cerec cad cam milling system.The lithium disilicate dental cerec block is partially crystallized during processing and has a light purple color.They are collectively called blue porcelain blocks.In this state,the hardness of the dental lithium disilicate block is relatively low,which makes it easy to grind the equipment.
In general,the prosthesis after cutting needs to be crystallized at 840 ° C,and the sintering process takes about 25 minutes.During the crystallization process,the lithium disilicate dental cerec block has almost no shrinkage.

Feature of lithium disilicate dental cerec block
- Excellent mechanical strength
The three point bending strength is increased to 4+60Mpa,allowing CAD/CAM system to design with higher accuracy,reducing the processing dificulty o ultra-thin veneer and other restorations,and improving the strength and saftey of materials seated in the mouth.
- Simulate the hardness of a nature tooth
Compared with other types of materials,the hardness of glass ceramic(lithium disilicate dental cerec block) is colser to that of nature human teeth,which can reduce the excessive wear of the occulusion teeth caused by the hardness diference,and maintain the abrasion of the restorations and the surrounding teeth.
- Overall fitness,easy to seat
The scientific nanosmicron crystallization structure provides better edge stability and strutural accuracy for milling restoration,effectively simplifies the operation process of repeated seating and polishing,and realizes the efficient fitting o the technician processing and clinical seating teeth.
- More intuitive transparency aesthetics
As an all-ceramic material with a shrinkage ratio close to zero,it can provide great convenience for efficient design and digital processing,and provide you with idear and comfortable instant diagnosis and treatment experience combined with the rapid crystallization process.
