LITHIUM SILICATE GLASS CERAMIC AND METHOD FOR FABRICATION OF DENTAL APPLIANCES |
摘要 |
The present invention relates to preparing an improved lithium silicate glass ceramic for the manufacture of blocks for dental appliance fabrication using a CAD/CAM process. The lithium silicate material has a chemical composition that is different from those reported in the prior art including 8 to 10% of germanium dioxide in the final composition. The softening points are close to the crystallization final temperature of 830° C. indicating that the samples will support the temperature process without shape deformation. The resulting material has improved castability and higher density. |
