Clinical cases – step-by-step |

IPS e.max

®

lithium disilicate anterior crown cemented with Multilink

®

Automix

Excess cement material is light-cured with a poly-
merization device (650 mW/cm

2

: 3 seconds or

1,000 mW/cm

2

: 1 – 2 seconds per quarter surface)

at a distance of 10 mm using the quarter technique.

Excess material is now easily removed with a scaler.

In order to prevent oxygen inhibition, the restora-
tion margins are covered with glycerine gel/air block
(e.g. Liquid Strip) immediately after the removal of
excess.
Subsequently, all cementation joints are light-cured
(approx.1,200 mW/cm

2

) again for 20 seconds.

If non-translucent, opaque restorative materials are
used, self-curing must be completed.

Proximal areas are reworked using finishing and
polishing strips. The occlusion and function are
checked. Restoration margins are polished using
polishers (Astropol) or disks.

A thin layer of Fluor Protector is applied. The varnish
is evenly dispersed and dried with an air syringe.

The mixed Multilink

®

Primer A/B is applied on the

entire bonding surface (starting from the enamel
surface) using a microbrush and rubbed in for
30 seconds.
Excess Multilink Primer is dispersed with air until the
mobile liquid film is no longer visible.

Multilink Automix is dispensed from the automix
syringe and directly applied on the restoration.

The restoration is seated and held in place
maintaining stable pressure.
