Lithium Disilicate Ceramic

Ips e max is a lithium disilicate glass ceramic that has optimized translucency durability and strength for full anatomical restorations.

Lithium disilicate ceramic. 8 10 with its relatively low refractive index outstanding optical properties such as translucency. What is lithium disilicate. Crystallization of lithium disilicate is heterogeneous and can be achieved through two different processing routes a two stage or three stage process depending on whether the glass ceramic is intended to be used as a machinable block. This option provides a strong stable full contour lithium disilicate crown.

Lithium disilicate has found applications in dentistry as a material for crowns in the form of li 2 si 2 o 5 lithium disilicate has an unusual microstructure that consists of many randomly oriented small and. Lithium disilicate ls 2 glass ceramic is ideally suitable for the fabrication of monolithic restorations or veneered restorations in the anterior and posterior region due to its natural looking tooth colouring and excellent light optical properties this material produces impressive results. 9 the term hybrid refers to an incisal third cut back by the lab either cad premilling or after milling by hand and stacked with layering ceramic for depth and translucency. 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.

8 9 this unique crystalline structure enables size shape and density to be controlled allowing for greater strength and durability. Lithium disilicate dental ceramics is classified as a glass ceramic subgroup of particle filled glass and contained approximately 70 of crystalline lithium disilicate filler. Due to the use of new technologies and optimized processing parameters ips e max lithium disilicate has evolved beyond previously available lithium disilicate ceramics. A hybrid lithium disilicate full coverage crown provides excellent esthetics and strength.

Lithium disilicate glass ceramic contains approximately 70 by volume needle like crystals in a glassy matrix. Lithium disilicate will continue to increase in use and be further reinforced with zirconia or other elements. The mechanism of crystallization as compared to leucite glass ceramics is a volume crystallization where the crystals nucleate and grow throughout the glass. They are widely used as dental ceramics due to their strength machinability and translucency.

This dental material is a type of glass ceramic composed of lithium which is a soft silvery white metal and silicon which is a. New hybrid full ceramic materials are coming into the market.
