Try-in and adhesive placement of tooth-coloured
restorations
Step by Step
For detailed information also refer to the Instructions for
Use of the respective products.
1. Removal of the temporary restoration
Remove possible residue of the temporary luting com-
posite from the cavity or the prepared die with a polishing
brush and an oil- and fluoride-free cleaning paste. Rinse
with water spray.
Note:
Use only eugenol-free temporary luting agents (e.g.
Provilink
® ), as eugenol may inhibit the polymerization of
Variolink II. When working on inlays and using
Systemp
® .inlay/Systemp ® .onlay as a temporary restorative
material, the application of a temporary luting composite is
generally not necessary.
2. Try-in of the restoration
To aid in achieving optimum final restoration results, try-in
of the restoration with a try-in paste (e.g. Variolink
® II Try-In).
To avoid fracture of the restoration, do not check the
occlusion at this stage. If necessary, make corrections with a
fine diamond at medium speed and with slight pressure.
Polish ground surfaces.
3. Isolation
When applying the adhesive luting technique with
composites, isolation with a rubber dam is recommended.
Restoration – pre-treatment
Note:
The following steps “Restoration 4a and 5a” may also be
done by the dental assistant in order to relieve the dentist.
4a. Cleaning
Rinse off the glycerine gel with water and dry the
restoration with water- and oil-free air.
5a. Pre-treatment of the restoration
According to the instructions of the manufacturer.
Cavity / Preparation – pre-treatment
4b. Cleaning
Clean cavity/preparation with water spray and dry.
5b. Pre-treament of the cavity
– Apply phosphoric acid gel (37% e.g. Total Etch) to the
prepared enamel and then flow the etchant onto the
prepared dentin. Use a disposable brush or syringe tip to
push the etchant into any restricted areas of the
preparation, leave for 15–30 seconds on enamel and for
10–15 seconds on dentin.
– Remove all etchant gel with av vigorous water spray for
at least 5 seconds. Excess water is removed with either:
a) the application of 1-2 bursts of clean, dry air or
b) high-volume evacuation tip directly over the preparation
surface for 1-2 seconds, or
c) blotting with a clear applicator or lint-free absorbent
material.
– Do not overdry dentin, moist preparation surfaces
should be apparent.
– The etched enamel surface should have a chalky white
appearance. If not, or if the etched enamel surface has
been contaminated, repeat etching.
– Subsequently, apply the adhesive (see instructions for use
Excite DSC, Syntac)
Note:
Using a matrix band in the proximal regions inhibits
accidental etching of the adjacent teeth and facilitates the
subsequent removal of excess Variolink II. Hold matrix band
in place with a suitable interdental wedge.
6. Variolink II
Mix Variolink II in a 1:1 ratio on a mixing pad for 10 s (mix
carefully with a spatula). The working time of the mixed
Variolink II is about 3.5 min., at a temperature of 37 °C/99 °F.
