after completion of the polymerization procedure, completely remove Sr Gel from the restoration using running water
and/or a steamer. carefully remove the restoration from the die. If the restoration is removed at a later stage, it is
advisable to warm up the stone die by means of steam/hot water. finish the restoration with cross-cut tungsten carbide
burs and fine diamonds. It is advisable to use low speed and light pressure. make sure to rework the entire restoration to
remove the inhibition layer of approximately 30 µm. carefully taper the margins of the restoration, lightly grind the
margins, and adjust proximal and occlusal contact points. Subsequently, recreate a lifelike tooth shape and surface
structure. the inhibition layer must be removed from the entire Sr nexco surface.
Polishing
Finishing
carefully smooth out the ridges of the occlusal surface and
proximal surfaces with rubber polishers and silicone
polishing wheels. Pay particular attention to the margins in
order to avoid rendering them too short.
Prepolishing and high-gloss polishing
the restorations are prepolished and polished to a high
gloss using a goat hair brush, cotton or leather buff as
well as Universal Polishing Paste. Use low speed and slight
pressure for prepolishing and high-gloss polishing. adjust
the pressure at the handpiece, not with the polishing
motor. In order to optimally polish the occlusal surfaces,
we recommend modifying the goat hair brushes to
become star-shaped so that only the desired areas can be
polished due to the smaller size of the brush. depending
on the type of high gloss desired, leather buffing wheels
can be used to achieve a high shine, while cotton buffs are
used to achieve a lesser degree of lustre.
Remove SR Gel and carefully remove the restoration from the die. Remove the inhibition layer and finish the surface with cross-cut burs.
