Lithium disilicate

Lithium disilicate is a material consisting of a glass ceramic reinforced with lithium salts. Thanks to its characteristics, it is a material widely used in dentistry for the production of dental prostheses such as dental crowns and bridges, but also for other applications such as inlays and veneers.
Characteristics of lithium disilicate
The main feature of lithium disilicate is resistance; in fact, compared to other glass-ceramics, it has a resistance about 3 times greater. It can be used as a structure then covered with ceramic.
This is precisely its strong point: it manages to combine a very resistant structure, which can last over time, with the superlative aesthetics of ceramic. Thanks to its opalescence, it allows light to pass through without giving unnatural reflections.
The lithium disilicate is adhesively cemented becoming one with the underlying tooth.
The artificial element consolidates and consolidates with the natural tooth thus obtaining an optimal chromatic effect.
Applications of lithium disilicate: dental crowns and bridges
Lithium disilicate is especially indicated for the fabrication of single monolithic restorations. The disilicate crowns are very resistant and have a high aesthetic effect. With a zirconium oxide substructure, it can also be used for the fabrication of bridges in the lateral and posterior areas of the dental arches.
In addition to crowns and bridges, disilicate can also be used for thin dental veneers and minimally invasive inlays and onlays.
Advantages of lithium disilicate
- - It is a material suitable for highly aesthetic solutions thanks to its opalescence which allows an optimal passage of light; - it is a long-lasting solution, thanks to its resistance; - it involves a minivasive preparation; - it has a wide range of use.
