C
ontraindication
The product is contraindicated
– for intraoral luting;
– if the stipulated working technique cannot be applied;
– if the patient is known to be allergic to components of Multilink Hybrid
Abutment.
Side effects
Systemic side effects are not known. In rare cases allergic reactions to
individual components have been reported.
Interactions
Phenolic substances (e.g. wintergreen oil, eugenol) inhibit polymerization.
Therefore, materials containing these components must not be used.
Oxidative disinfectants (e.g. hydrogen peroxide) may interact with the
initiator system and impair the setting process. As a result, the automix
syringe must not be disinfected with oxidative agents. The syringe can be
disinfected by wiping it with medical alcohol for example.
Application
The contact surfaces must be meticulously prepared in order to ensure an
optimum adhesive bond between the base and the ceramic structure. The
procedure is described below. The same procedure is used for the Hybrid
Abutment and the Hybrid Abutment Crown.

1. Preparation of the base
The following procedure should be observed in the preparation of the base
for the cementation with the ceramic structure:
– The base should be prepared according to the instructions of the manu-
facturer.
– The base is cleaned in an ultrasonic bath or with a steam cleaner and
then dried with blown air.
– The base is screwed to the model analog.
– The ceramic structure is placed on the base and the relative position is
marked with a waterproof pen. This makes it easier to attain the correct
relative end position when the parts are assembled at a later stage.
– The emergence profile of the base must not be blasted or modified in any
way!
– If the manufacturer recommends that the contact surfaces be
sandblasted, the following procedure should be observed:
– Hard modelling wax is applied to protect the emergence profile, since
this type of material is easy to remove later on.
– The screw channel is also sealed with wax.
– The bonding area surface is carefully blasted according to the
instructions of the manufacturer.
– An instrument and a steam jet are used for cleaning. The wax has
to be removed meticulously.
– After the bonding surface has been cleaned, it must not be contaminated
under any circumstances, as this would impair the bond.
– Monobond Plus is applied on the clean bonding surface and allowed to
react for 60 s. After the reaction time, any residue is dispersed with air
that is free of water and oil.
– The screw channel is sealed with a foam pellet or wax. The bonding sur-
face must not be contaminated in the process.
