In order to individualize restorations in the incisal area so that they correspond with their natural model, the IPS Empress
CAD restoration is additionally veneered using opalescent IPS Empress Esthetic Veneer ceramic materials. The cut-back
technique is very efficient if the fully anatomical anterior crown or the veneer are first designed according to the definite
final shape. After that, the incisal third is reduced and subsequently provided with an individualized aesthetic veneer.
