Lithium Disilicate Glass Ceramic Crowns

A study published by the journal of clinical diagnostic research concludes that compared to other ceramics lithium disilicate had the best translucency which is an important factor to consider for esthetics.

Lithium disilicate glass ceramic crowns.

Benefits of lithium disilicate. 8 9 this unique crystalline structure enables size shape and density to be controlled allowing for greater strength and durability. 4 55 reprinted from höland w beall gh. The purpose of this study was to evaluate the fracture strength of single crowns made of the different types of lithium disilicate glass ceramics.

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 glass ceramic ldg provides desirable mechanical properties chemical resistance biocompatibility diminished plaque accumulation accuracy of fit esthetics as well as wide indications including thin veneers inlays onlays crowns fixed dental prostheses in the anterior and premolar region and implant superstructures. Lithium disilicate ls2 glass ceramic is ideally suitable for the fabrication of monolithic single tooth restorations. Emax based all ceramic prostheses are rapidly gaining widespread popularity in cosmetic dentistry due to their excellent esthetics durability and strength.

This innovative ceramic provides highly esthetic results and compared to other glass ceramics demonstrates a strength that is 2 5 to 3 times higher. A fitting of the precursor blue glass ceramic lithium metasilicate glass ceramic crown. Emax is an all ceramic system that is based on lithium disilicate glass and consists of quartz lithium dioxide phosphoroxide alumina potassium oxide and trace elements. Lithium disilicate glass ceramic contains approximately 70 by volume needle like crystals in a glassy matrix.

People are conscious about their smile and how they look so lithium disilicate crowns are popular. B crown with the same shape but after final heat treatment shaded and glazed and cemented as lithium disilicate glass ceramic with dental color of the final product. Lithium disilicate glass ceramics with high mechanical strength are being widely used as ingots for heat pressing technique and blocks for cad cam processing in clinical dentistry as aesthetic prosthetic materials. Lithium disilicate glass ceramic ips e max cad crown exhibits higher fatigue load to reach the failure value than the zirconium oxide crown y tzp 14.

They are widely used as dental ceramics due to their strength machinability and translucency.
