Dental lithium disilicate glass ceramics: a complete analysis of properties and applications

First, the characteristics of lithium disilicate glass ceramics

Dental lithium disilicate glass ceramics, referred to as lithium disilicate ceramics, is now a new type of material widely used in dental oral restoration, 

China's main factories in the production of aidite, upcere, honchon smile, etc., 

the main characteristics of the high strength and excellent aesthetic properties, its characteristics mainly include the following points:

1. high mechanical strength: lithium disilicate ceramics usually have a flexural strength of 400 MPA and excellent fracture properties, which can withstand

 the pressure of chewing in the oral cavity and ensure the long-term stability of the restorations.

2. Good biocompatibility: the material is non-toxic and harmless to human tissues and has good biocompatibility.

3. Outstanding aesthetic effect: lithium disilicate ceramic has similar color and light transmittance with natural teeth, which can realize highly aesthetic restoration effect.

Second, the preparation process of lithium disilicate glass ceramics

Lithium disilicate glass ceramics preparation process has 3 key processes, due to space limitations, just introduce these 3 processes.

1. batching and melting: mix the raw materials according to a specific ratio and melt them at high temperature to form a homogeneous glass liquid.

2. Molding and Heat Treatment: The liquid glass is poured into the desired shape and subsequently heat treated to improve the crystallinity and mechanical properties of the material.

3. Processing and polishing: the molded ceramics are finely processed and polished to achieve the desired shape and surface finish.

Third, the application of lithium disilicate glass ceramics in dental restoration

1. dental veneers: the use of lithium disilicate ceramics to make dental veneers, can improve the color, shape and alignment of the teeth, enhance the overall aesthetics, mainly for 

yellow teeth, tetracycline teeth and so on.

2. Crowns and bridges: Because lithium disilicate ceramics have good flexural strength, good fracture toughness and high coefficient of thermal expansion, they can be used to 

make all-ceramic crowns and bridges to restore the chewing function and appearance of teeth.

3. Dental Implants: As a material for dental implants, lithium disilicate ceramics are able to form a good bond with the surrounding tissues, improving the stability and service life of the implants.

Dental lithium disilicate glass ceramics with its excellent bending strength, fracture toughness, good biocompatibility, excellent aging resistance, so it has a wide range of application 

prospects, in the field of modern dental restoration occupies an important position. With the 

continuous progress of technology and material optimization, I believe that lithium disilicate ceramics will bring more patients more beautiful, healthy teeth restoration effect.
