Lithium disilicate

However, Lithium disilicate is ideal for no-prep esthetic veneers because of its relative high strength coupled with the different available translucency levels which provides almost the “perfect “esthetic restorations. Lithium disilicate can either be milled with the CAD/CAM technology from a block form, or it can also be pressed from an ingot. Companies often offer ingots with different opacities depending on the type of treatment plan. There are High opacity, Medium opacity, Low translucency High translucency ingot. The selection of an opacity depends largely on the type of preparation and the look of the natural teeth. With the CAD/CAM technology, the whole restoration is digitally designed. Restorations made of lithium disilicate can be veneered to highly-esthetic ones, or they can be high-quality monolithic restorations, so the material offers both options. This material boasts with versatility on the market in the form of adhesive, self-adhesive or conventional techniques for cementation. Its main strength is that it offers high-quality full contoured restorations made from only one material, avoiding the mix of two different materials. In addition, Lithium disilicate can also be used with the hybrid design approach where it is veneered with a nano-fluorapatite porcelain.
