LITHIUM DISILICATE CERAMICS

The fixed prothesis have an important place in restorative dentistry. clinicians are constantly seeking the esthetic and resistant material that can be used for different clinical applications. developments in all ceramics replaced the use of traditional porcelainfused-to-metal restorations. all-ceramics are classified such as glass ceramics, zirkonium oxide and aluminium oxide according to the core structure. glass core structured lithium disilicates are esthetic and resistant materials which are indicated for new treatment options. lithium disilicate has the potential to provide new options for a varietry of restorative indications. this article presents a rewiev of the literature about lithium disilicate ceramics.
