Ceramic Lithium Disilicate

Lithium disilicate will continue to increase in use and be further reinforced with zirconia or other elements.

Ceramic lithium disilicate.

Lithium disilicate has an unusual microstructure that consists of many randomly oriented small and interlocking plate like needle like crystals. The ability to fabricate a crown or veneer from a single block of ceramic material called lithium disilicate is one of the most exciting changes in the field of restorative dentistry. Lithium disilicate ls 2 glass ceramic is ideally suitable for the fabrication of monolithic restorations or veneered restorations in the anterior and posterior region. New hybrid full ceramic materials are coming into the market.

They are widely used as dental ceramics due to their strength machinability and translucency. Never before has a material been able to combine high strength high esthetics and ease of use into one product until now. Lithium disilicate glass ceramics ldgc are aesthetic dental materials derived from sio2 li 2 o al 2 o 3 k 2 o zro 2 p 2 o 5 glass systems via solid state reaction route 140 143. Lithium disilicate has found applications in dentistry as a material for crowns in the form of li 2 si 2 o 5.

What is lithium disilicate. Ldgcs are known for their high strength and they are the earliest known system for dental restorations 18 19 144 147. Due to its natural looking tooth colouring and excellent light optical properties this material produces impressive results. They will continue to be developed but it will take years to prove or disprove their acceptability.
