Lithium Disilicate

Because lithium disilicate can be fully light-cure bonded or cemented using a self-etching primer with conventional resin-cement techniques IPS e max also provides options for cementation Conventional self-etching primer cement is ideal for full crowns For partial and veneer preparations in which an adhesive protocol will be used full light-cure bonding is preferred Case Report A 42-year

An overview of monolithic zirconia in dentistry

High translucent zirconia crowns (two different brands) were found to have higher fracture resistance (2795 and 3038 N) than heat-pressed monolithic lithium disilicate crowns (1856 N) porcelain-veneered zirconia crowns (2229 N) and porcelain-veneered high translucent zirconia (1480 and 1808 N) in a study by Johansson et al

The ceramic specimens comprised of standardized lithium disilicate (polished) zirconia (polished glazed polished then glazed) blocks (n=10) All ceramic specimens were wet-finished (pumice/polishing cloth) cleaned (ultrasonic bath/5min/distilled water) glazed and stored for 24hrs at 37C Before testing the surface roughness of all ceramic specimens was measured using a non-contact 3D

Lithium Disilicate

Lithium disilicate glass-ceramics are derived from the SiO 2 –Li 2 O system that was first investigated by Stookey at Corning Glass Works in the 1950s They consist of a large volume fraction of up to 70% fine rod-like entangled Li 2 Si 2 O 5 crystals and a minor amount of lithium orthophosphate (Li 3 PO 4) crystals that are randomly oriented and uniformly dispersed in the glassy matrix

Influence of Teeth Preparation Finishing on the Adaptation

The polishing step of teeth preparations for crowns is a step often performed so that there is an increased time during the clinical procedure The aim of this study is to evaluate the marginal and internal adaptation of all-ceramic CAD/CAM lithium disilicate crowns in polished preparations for crown and nonpolished preparations for crowns For this purpose 20 first molars were selected

An Emax crown is made from lithium disilicate and is a very cosmetic looking restoration This material bonds relatively well to tooth structure so it might be a good solution for someone who has crowns that come off a lot The Emax material is very strong but not as strong as the all Zirconia option Zirconia crowns often referred to by the brand name "Bruxzir" are made from a
