Lithium Disilicate Block: Revolutionizing Dental Restorations

Jul 05,2023 | dental supply

When it comes to dental restorations, like crowns, veneers, and inlays/onlays, clinicians and dental technicians are constantly seeking materials that offer both strength and aesthetic appeal. One breakthrough material that has gained significant popularity in recent years is the lithium disilicate block. In this article, we will explore the properties and advantages of lithium disilicate blocks and how they have revolutionized the field of restorative dentistry.

Lithium disilicate is a glass-ceramic material that combines the strength of ceramics with the esthetics of dental porcelain. This unique combination of properties makes it an ideal choice for fabricating dental restorations that require both durability and a natural appearance. The lithium disilicate block is made of a pre-sintered or densely pressed form of the material, which allows for easy milling and shaping by dental milling machines.

One of the major advantages of lithium disilicate blocks is their exceptional strength. They offer high flexural strength and fracture toughness, making them suitable for use in posterior restorations that undergo significant pressures during mastication. This strength also translates into increased longevity, with lithium disilicate restorations showing excellent resistance to wear and chipping compared to traditional porcelain restorations.

In addition to its strength, lithium disilicate blocks also offer exceptional optical prope
