Ivoclar Vivadent Zenostar - Manual (Page 47)

Is it mandatory to polish the surfaces of monolithic restorations before the crowns are seated?
Yes, polishing of the surface, particularly in the occlusal areas, is a must. Failure to adhere to these guidelines may lead to damage
to the opposing teeth.
Can Zenostar restorations be conventionally cemented?
Zenostar restorations can be seated using an adhesive, self-adhesive or conventional luting protocol. For conventional cementation,
however, an appropriately retentive preparation design must be observed. If this is not possible, an adhesive luting or self-adhesive
luting protocol should be preferred, e.g. with Multilink Automix or SpeedCEM. Vivaglass
® CEM PL is available for conventional
cementation. All the luting materials indicated are products of Ivoclar Vivadent. We advise against the use of conventional phosphate
cements, since they negatively affect the light transmission through the all-ceramic and therefore compromise the esthetic
appearance of all-ceramic restorations. Inlay-retained bridges fabricated in the press-on technique must be adhesively cemented.
Why should operators always use Deep Dentin when veneering Zenostar T frameworks with IPS e.max Ceram?
Zenostar T features a higher translucency than Zenostar MO. If the veneer is more than one millimetre thick, the brightness value
may drop if only Dentin materials are used. Consequently, it is recommended to apply IPS e.max Ceram Deep Dentin underneath
the Dentin material. For more detailed information, please refer to the IPS e.max Ceram Instructions for Use.
