Ivoclar Vivadent IPS e.max CAD Chairside v.1 - Handbuch (Seite 76)

24
IPS e.max CAD LT blocks are ideally suitable for the fabrication of larger restorations (partial crowns, crowns) on prepared
teeth that are not or only slightly discoloured. Due to the higher brightness compared with IPS e.max CAD HT, a
“greying“ of the restoration is prevented.
Individualized characterizations and glaze are applied before the combined Crystallization and Glaze firing is conducted.
Because of the combined firing, processing is very efficient and leads to a highly esthetic result quickly and easily.
Preparation
After the determination of the tooth shade, preparation is carried out according to the preparation guidelines. As a
preparation for intra-oral imaging, the cleaned and dried preparation is covered with IPS Contrast Spray Chairside (blue-
lemon or cream-lemon) with one short spray discharge.
