Ivoclar Vivadent Virtual - Manual (Page 3)

Composition
Virtual impression materials are addition-reaction silicones containing vinylpolysiloxane,
methylhydrogensiloxane, an organoplatinic complex, silica and food dyes.
Indication
The Virtual line of addition-silicone (vinylpolysiloxane) impression materials is recommended for
use to create highly detailed impressions of the hard and soft tissues of the oral cavity.
– Final impression used for the fabrication of indirect restorations (crowns, bridges, inlays,
onlays and veneers)
– Dental implant impressions
– Matrix from “wax-ups“ or for treatment planning, study models
– Edentulous impressions
– Matrix used to create temporary restorations
Each viscosity provides specific attributes to meet the needs of the dental professional.
Contraindication
The use of Virtual impression materials is contraindicated if the patient is known to be allergic to
any of the ingredients in Virtual impression materials.
Side Effects
None known to date
Interactions
The setting of vinylpolysiloxanes is inhibited by latex gloves.
Do not touch preparations or retraction cords with latex gloves. It is recommended that operators
wash their hands thoroughly or use vinyl gloves in order to eliminate all traces of impurities,
specifically when hand mixing putty. Other materials which may inhibit the set of impression
materials include rubber dam, retraction cords and retraction cord fluids. If the operator suspects
that the preparation has been contaminated, it is recommended that the preparation be rinsed
and dried to eliminate all traces of impurities.
Application
– Putty (Regular and Fast Set)
Very high viscosity vinylpolysiloxane that provides easy mixing and the hydraulic forces
necessary to extend wash material into the sulcus providing a detailed impression of pre-
pared margins. The putty viscosity maintains outstanding detail reproduction when used
alone. Recommended impression techniques include Putty/Wash One-Step and Putty/Wash
Two-Step.
Important: Avoid wearing latex gloves when handling putty, putty jars, and dosing spoons
(see note under interactions).
1. Take equal amounts of base (blue) and catalyst (white) using the color coded dosing
spoons.
2. Hand mix the identical portions of Virtual Putty base and catalyst until you obtain an
evenly colored mixture (approximately 30 seconds of mixing time). A proper mixture should
have no streaks. Note that equal proportions of base and catalyst must be used in order
to obtain proper setting times. A larger quantity of catalyst will not accelerate the setting
