Ivoclar Vivadent Vivacap - Manual (Page 2)

Indications
Class I and II restorations
Contraindication
Vivacap Non-Gamma-2 is contraindicated
– if proximal or occlusal contacts with other metal
restorations are present
– if the patient suffers from impaired renal function
– if the patient is known to be allergic to any of the
components of amalgam
– for retrograde or endodontic restorations
– as a core build-up material under crowns or inlays
– as a filling material under metal crowns
– for children under six years of age
– for pregnant or nursing women
– if the stipulated working technique cannot be applied
Side effects
– In individual cases, hypersensitivity, allergic reactions, or
electrochemically-induced local reactions may occur.
– Mercury may have a sensitizing effect on the skin and
lungs, or act as a nephrotoxin or neurotoxin.
– Electrochemical processes may cause lichen planus of the
oral mucous membrane.
– After the placement or removal of amalgam restorations,
a short-term increase of the mercury concentration in the
blood or urine may occur.
Interactions
Mercury that has escaped during condensing or amalgam
that has not set may cause amalgamation or galvanic
reactions (electrochemically-induced local malaise, i.e.
alterations in the sense of taste) when the restoration
comes in contact with other metal restoratives. If these
symptoms persist, the amalgam should be replaced with
another material.
Application
Relative isolation with e.g. cotton rolls.
Moisture contamination of the amalgam before it has set
completely can detrimentally affect physical properties such
as stability and corrosion resistance.
Mixing times for Vivacap Non-Gamma-2
Silamat
® S5, S6 10 s.
Mixers of other competitors should demonstrate a high
starting torque and achieve approx. 4,500 rpm. The use of
low-speed amalgamators is not recommended. The mixing
time is 10 s. Longer mixing times result in a softer
consistency and slightly improved stability, without
significant effect on the other properties.
Base/liner
Cover very deep areas of the cavity near the pulp with a
small amount of calcium hydroxide cement. The base/liner
must be able to withstand condensation pressure. Line the
cavity with a mechanically stable cement such as Vivaglass
Liner (light-curing glass ionomer cement).
Placing the restoration
After mixing, open the capsule, apply the pliable amalgam
to the cavity in portions and condense and model it.
Ultrasonic condensers should not be used.
The working time of Vivacap is approx. 4 minutes.
Polishing
The restoration should not be polished until at least 24
hours after placement. Suitable tungsten-carbide finishers
or other polishing instruments (Politip-F and Politip-P) can
be used. Make sure to provide steady, adequate spray
cooling and suction.
Safety notes
– Mercury presents a health hazard if incorrectly handled.
Spillages of mercury should be removed immediately,
including from places which are difficult to access. Use a
plastic syringe to draw it up. Smaller quantities can be
covered by sulphur powder and removed. Avoid
inhalation of vapour.
– As the removal of existing amalgam restorations results
in the additional release of mercury, clinically sound
amalgam restorations should not be removed. The
removal of existing amalgam restorations should be
avoided during pregnancy or lactation in particular.
– When removing amalgam restorations, the corresponding
safety notes must be observed: Wear nose/mouth
