It includes alloys, ceramics, and high-performance polymers such as zirconia, Ni-Cr, lithium disilicate
, and so on.
There are many CAD/CAM blocks with advantages, such as biocompatibility; durability; esthetics; fewer clinical stages; rapid production, cost effectiveness; different contents; and physical properties, such as lithium disilicate
glass ceramic (GCs), leucite-reinforced GCs, fieldspathic GCs, aluminum-oxide, and yttrium tetragonal zirconia polycrystal (2).
E.max: IPS e.max lithium disilicate
(Ivoclar Vivadent, Liechtenstein, Germany).
Comparison of the marginal fit of lithium disilicate
crowns fabricated with CAD/CAM technology by using conventional impressions and two intraoral digital scanners.
Due to the different levels of translucency, the different build-ups of the stump, we have decided to use press ceramic made from lithium disilicate
(LS2) material using the cut back technique.
To guarantee evenness of the specimens, inhibition of polymerization by oxygen and easy placement of ceramic disc (Lithium Disilicate
, IPS Emax, Ivoclar Vivadent-1mm) on resin cement Mylar strips (DuPont Mylar 0.002 gauge/60mm thick) were used.
The primary crystal types today are leucit, lithium disilicate
The ZirconLITH Dental features advanced technology that allows handling high percentage loading of light reactive polymers with particles such as Zirconium and Lithium Disilicate
. The 3D parts produced can then be further processed using furnaces to create very hard, durable units.

The aesthetic necessity of the final work resembled the rest of the lower arch, which was being rehabilitated with IPS e.max crowns (Ivoclar Vivadent), lithium disilicate
, and the laboratory was asked to apply feldspathic ceramics to the metal structure in the region where the crowns would later be cemented.
