Clinical cases – step-by-step
The temporary restorations are removed. The prepa-
rations are cleaned with a polishing brush and an oil-
and fluoride-free cleaning paste (e.g. Proxyt
® fluo-
ride-free). Subsequently, the preparations are rinsed
with water spray and dried with oil-free air.
Subsequently, the gel is thoroughly rinsed off with a
vigorous water spray for at least 5 seconds. Excess
moisture is removed leaving the dentin surface with
a slightly glossy wet appearance (wet bonding).
Monobond ® Plus is applied onto the pretreated
surface, allowed to react for 60 seconds and then
thoroughly dispersed with air.
For the esthetic inspection, Variolink ® Veneer Try-in
Paste can be used. After the try-in, the Try-In Paste
is thoroughly washed off with water spray, and the
restoration is dried with oil- and moisture-free air.
Syntac ® Primer is applied on the preparation using
a brush, gently rubbed in and allowed to react for
at least 15 seconds. Excess of Syntac Primer is
dispersed and thoroughly dried. It is not rinsed off.
The treatment field is isolated with a rubber dam
(e.g. OptraDam
® ) and the preparation is cleaned
again according to the steps described above.
Subsequently, the preparation is dried with oil-free
air. Overdrying must be avoided.
Etching is performed with 5% hydrofluoric acid
(e.g. IPS
® Ceramic Etching Gel) for 20 seconds.
Subsequently, the preparation is rinsed thoroughly
with water and dried with oil-free air.
Syntac Adhesive is applied and allowed to react
for 10 seconds. Subsequently, the preparation is
thoroughly dried with an air syringe. It is not
rinsed off.
Total Etch (37% phosphoric acid gel) is applied. The
phosphoric acid is allowed to react on the enamel
for 15 – 30 seconds and on the dentin for
10 – 15 seconds.
