Ivoclar Vivadent Multilink Hybrid Abutment - Manual (Page 3)

– The ceramic structure is cleaned in an ultrasonic bath or with a steam
cleaner and then dried with blown air.
– After the cleaning step, the bonding surface must not be contaminated,
since this would negatively influence the bond.
– Wax can be applied to protect the outer surfaces and the glazed areas.
– The bonding surface is etched with 5% hydrofluoric acid (IPS Ceramic
Etching Gel) for 20 s.
– Subsequently, the bonding surface is thoroughly rinsed under running
water and then dried with oil-free air.
– Monobond Plus is applied to the clean bonding surface and left to react
for 60 s. After the reaction time, any residue is distributed with blown air
that is free of water and oil.
2.2 Preparing ceramic structures made of zirconium oxide (ZrO
2
)
The following procedure must be observed in the preparation of the ceramic
structure for the cementation with the base:
– In order to facilitate its handling, the ceramic structure is attached to a
holder (e.g. Microbrush) before it is blasted.
– The outer surfaces of the ceramic structure are protected with a wax
coating.
– In order to better control the blasting procedure, the bonding surface can
be coloured with a permanent marker.
– The bonding surface of the ceramic structure is cleaned by means of
blasting with Al
2
O
3
100 µm at max. 1 bar and at a distance of max.
1–2 cm from the blasting nozzle (The instructions of the manufactur-
er must be observed).
– The ceramic structure is cleaned with a steam jet or in an ultrasonic bath.
– After cleaning, the bonding surface must not be contaminated under any
circumstances, since this may negatively influence the bonding results.
– Monobond Plus is applied to the clean bonding surface and allowed to
react for 60 s. After this reaction time, any residue is dried with air that is
free of water and oil.
3. Cementation with Multilink Hybrid Abutment
The following instructions must be observed in the cementation procedure:
– The cleaned and conditioned components (ceramic structure, base) are
laid out ready for cementation.
– The subsequent cementation procedure must be carried out
quickly and without interruption. The working time of Multilink
Hybrid Abutment is approx. 2 min. at 23 °C/73 °F (± 1°C/2 °F).
– As a general rule, a new mixing tip is attached to the Multilink Hybrid
Abutment syringe prior to each use.
– A thin layer of Multilink Hybrid Abutment is directly applied from the
mixing syringe to the bonding surface of the base and the bonding sur-
face of the ceramic structure.
– The mixing tip is left on the Multilink Hybrid Abutment syringe until the
next use. The remaining cement polymerizes in the tip and functions as a
seal.
– The ceramic structure is placed on the base in such a way that the posi-
tion markings are aligned.
– The parts are lightly and evenly pressed together and the correct relative
position of the components is checked (transition between the base and
ceramic structure).
– Subsequently, the parts are tightly pressed together for 5 s.
– Excess in the screw channel is carefully removed with, e.g. a Microbrush
or brush using rotary movements.
– Important: Excess must not be removed before curing has started,
i.e. 2–3 minutes after mixing. For the purpose, a suitable dental
lab instrument (e.g. Le Cron) is used and the components are held
in place with light pressure in the process.
– Glycerine gel is applied (e.g. Liquid Strip) on the cementation joint to pre-
vent the formation of an inhibition layer. The glycerine gel must be
applied cautiously to avoid blending it with or displacing the composite.
The gel must be left on the cementation joint until polymerization is com-
plete.
– Next, the luting composite is auto-polymerized within 7 min.
– Important: The parts should not be moved until Multilink Hybrid
Abutment has completely cured. They can be held immobile with
e.g. diamond-coated tweezers.
– After the completion of auto-polymerization, the glycerine gel is rinsed
off with water.
– The cementation joint should be cautiously polished with rubber
polishers at a low speed (< 5,000 rpm) to avoid overheating.
– Any cement residue left in the screw channel is removed with suitable
rotating instruments.
– The restoration is steam cleaned.
Additional notes
– Multilink Hybrid Abutment should be processed at room temperature.
Low(er) temperatures may cause difficulty in dispensing and mixing the
material and may prolong the working and curing time.
– Unpolymerized material may stain clothing.
Warning
Contact of uncured Multilink Hybrid Abutment with skin/mucous membrane
and eyes must be prevented. In an unpolymerized state, Multilink Hybrid
Abutment may cause slight irritation and lead to a sensitization against
methacrylates. Commercial medical gloves do not provide protection against
the sensitizing effect of methacrylates.
Shelf life and storage
– Multilink Hybrid Abutment must not be used after the indicated date of
expiration.
– Storage temperature of Multilink Hybrid Abutment: 2–28 °C/36–82 °F
– Shelf life: see note on the syringe
– The mixing tip is left on the syringe after each use. The material left in the
tip will cure and the mixing tip will therefore serve as a seal.
