Cementation with Multilink

®

Hybrid Abutment

The following instructions must be observed in the cementation procedure:
– Lay out the cleaned and conditioned components (Telio CAD structure, Ti base) for cementation.
Carry out the subsequent cementation procedure quickly and without interruption. The working time of

Multilink Hybrid Abutment HO 0 is approximately 2 min at 23°C (± 1°C) or 73°F (± 1.8°F).

– As a general rule, attach a new mixing tip to the Multilink Hybrid Abutment HO 0 syringe prior to each use.
– Apply a thin layer of Multilink Hybrid Abutment HO 0 directly from the mixing tip to the bonding surface of the Ti base

and to the bonding surface of the Telio CAD structure.

– Leave the mixing tip on the Multilink Hybrid Abutment syringe until the next use. The remaining cement polymerizes in

the tip and functions as a seal.

– Place the Telio CAD structure on the Ti base in such a way that the position markings are aligned.
– Press the parts lightly and evenly together and check the correct relative position of the components (transition Ti base /

Telio CAD structure).

– Subsequently, tightly press the components together for 5 s.
– Carefully remove excess in the screw channel, e.g. with a microbrush or brush, using rotary movements.

– Apply glycerine gel (e.g. Liquid Strip) to the cementation joint to prevent the formation of an inhibition layer. Leave the

gel on the cementation joint until polymerization is complete.

– Next, the composite cement auto-polymerizes completely within 7 min.
Important: Do not move the components until Multilink Hybrid Abutment HO 0 has completely cured. Hold

them in place using e.g. diamond-coated tweezers.

– After completed auto-polymerization, rinse off the glycerine gel with water.
Cautiously polish the cementation joint with rubber polishers at a low speed (< 5,000 rpm) to avoid overheating.

Finally, polish the surface of the PMMA structure to a high gloss using polishing paste.

– If there is any cement residue in the screw channel, remove it using suitable rotary instruments.
– Clean the restoration in an ultrasonic bath or with the steam jet.

Important:

Do not remove circular excess cement before curing has started, i.e. 2-3 min after mixing. Use a suitable

dental lab instrument (e.g. Le Cron) for this purpose. Hold the components in place using light pressure.

Keep the cleaned and conditioned components that are to be cemented at hand.

Attach a new mixing tip to the Multilink Hybrid Abutment syringe prior to each use.
