The use of lithium disilicate glass ceramics?

Lithium disilicate glass ceramics is a kind of polycrystalline material composed of lithium disilicate crystal and glass matrix, which is widely used in many fields because of its excellent physical and chemical properties. The following is a detailed summary of its uses:

Dental prosthetics

Lithium disilicate glass ceramics is a kind of dental glass ceramics with the highest strength. It has good biocompatibility, excellent mechanical properties and mature die casting technology. It is widely used in the repair of veneer, inlay, onlay, single crown, three-unit fixed bridge, implant abutment and prosthesis. Its outstanding aesthetic properties allow the prosthesis to mimic the shine and light transmission of natural teeth, while its high strength and chemical stability ensure the long-term stability and durability of the prosthesis. For example, IPS e.maxPress is a new type of hot die-cast lithium disilicate glass ceramic, which is suitable for the production of all-porcelain veneers, all-porcelain crown Bridges and implant superstructures.

Glass ceramic reinforcement

Lithium disilicate can enhance the elastic modulus and Poisson's ratio of glass ceramics and improve their strength and stability. Lithium disilicate increases the silicon content in glass ceramics and forms strong silico-oxygen bonds, thus significantly improving the mechanical properties of the material. The results show that the elastic modulus and Poisson's ratio of glass ceramics are increased by 20% and 30% respectively after adding a certain amount of lithium disilicate. This enhancement effect makes glass ceramics more stable and stronger in practical applications.

Other potential applications

Although lithium disilicate glass ceramics are already widely used in dental restoration and glass ceramic enhancement, their excellent properties may also be suitable for other fields. For example, its good biocompatibility could make it potentially useful in biomedical engineering, such as as a bioactive coating or tissue-engineered scaffold. In addition, the high strength and aesthetic properties of lithium disilicate glass ceramics may also find new application opportunities in construction, electronics, aviation and other fields.

In summary, lithium disilicate glass ceramics is a multi-functional material, and its unique properties and wide application prospects make it play an important role in the future development of science and technology.
