adhesive surfaces of the abutment / core build­up depen­
dent on the material, as described under "Pretreatment of
the restoration" in the Visalys
use, unless prescribed otherwise in the relevant material
manufacturer's instructions for use.
The emergence profiles and screw channels, as applicable,
must be protected by suitable measures (e.g. wax, silicone
covers).
Application of the cementation composite
1. Apply Visalys CemCore on the inside surfaces of the
®
restorations and on the core or cavity surfaces, as
applicable. In the case of application in the mouth, the
processing time is reduced and the restorations must be
placed within 2 min.
2. Place the restoration on the core or in the cavity.
3. Removing excess
3.1. Remove after initial curing through brief exposure to light
or self­curing until the "gel phase"
The excess is either polymerized with a commercial­
ly available polymerization lamp (1,200 mW / cm
2 – 3 sec. oral and vestibular as well as mesial and distal
– i.e. at four points – or wait for the gel phase in self­cur­
ing. The excess, which is still soft­elastic, can be easily

removed with a scaler. After removal of the excess, the
cement joint should be light­cured again for 20 sec.
3.2. Removing without initial curing
Remove the excess directly, e.g. with a cotton pellet,
brush or foam pellet.
While removing the excess, the restoration has to be held in
its final position. All excess, especially in difficult­to­reach
approximal areas, has to be removed prior to final curing.
4. Final curing
After removal of excess, the cement joint can be cov­
ered with a glycerin gel or polyethylene glycol paste, e.g.
Visalys CemCore Try In Paste, to avoid the formation of
®
an inhibition layer. This can then be removed with water.
Wait for final curing, also under the restoration (see T ech­
nical Data table).
Translucent restorations can also be cured in several lay­
ers according to the specified polymerization times de­
pendent on the size of the light aperture.
5. Finishing
Rough cement joints can be finished and polished with
the appropriate instruments.
