Polish
the tooth with Xcem's Prophy Paste.
Isolate
tooth with rubber dam or cotton wool rolls.
Dry
tooth thoroughly, making sure the pits and fissures are clean and free from
debris.
Apply
tooth conditioner to cavity margins and extend to occlusal surface slightly. If
glass ionomer base then this can be acid etched.
Etch
enamel for 20 seconds and dentine for 10 seconds. Wash tooth surface with water
and dry tooth until enamel is chalky or has a frosty surface, if not observed
then apply another layer and immediately place Merge Bulk Fill.
APPLICATION

the needle by turning into the leur lock of syringe. Check by pulling the
application needle to ensure it is fully engaged with syringe. Squeeze piston
of syringe slowly and with constant pressure and check that the material comes
out freely from the application tip. Dispense Merge Bulk Fill directly into the
cavity and light cure it with suitable light curing instrument.
Discard
needle after use.
Application of
Merge Bulk Fill as restorative material (secondary use): Dispense the
required amount of material directly to fill the prepared cavity. The
dispensing needle is used which is provided along with the syringe in the pack
for proper dispensing at the right place and in right amount. Take care to fill
from base upward avoiding any void. Fill in the increment of 3mm and light cure
before adding the next layer. Apply controlled pressure to dispense the
material. If allergy incur discontinue use and consult heath professional.
CAVITY
PREPARATION:
Cervical
erosions:
Remove
decay and if cavity is deep, the deepest pulpcal floor should be lined with
Calcium hydroxide liner.
Isolate
the tooth, preferably with rubber dam. If cervical area discoloured, it should
be polished with fine grit non-fluoride paste. Dry tooth.
Brush
a thin layer of merge bond into and around the cavity taking care to extend it
beyond the margins of restoration. With dry gentle air stream spread Merge
bond. To wet Merge bond apply Merge Bulk Fill directly from syringe. Contour as
necessary. Transparent matrix should be used to obtain excellent adaptation and
surface finish.
Trim
excess and light cure for at least 40 seconds. If a dark shade has been
selected, a longer exposure is necessary. If the depth of cavity is greater
than restoration should be cured in 3= thick layers.
Other
erosions:: Minimal cavity prep is required.
Enamel
should be preserved even if it is undercut. If the cavity is very deep and
there is almost risk of pulp exposure, a Calcium hydroxide liner such as
Carecal is recommended,
For
posterior large fillings, a sandwich technique is recommended. A glass ionomer
base is required which is acid etched and bonded to merge.
Following
cavity prep, isolate tooth and dry the cavity. Fill cavity as mentioned.
Polishing:
Use fine grit stone and fine grit composite disks to relieve occlusal surface
and excess flash along the edges and cover with vanish. For class III and class
II, use of celluloid type strip matrix is recommended for excellent adaptation
and surface finish.
Check
bites with articulating paper and relieves as necessary if it is high. Check
with probe to make sure it has set hard. Adjust with stone if necessary.
Normally, light cure for 40 seconds,
however,
if deep pits then cure for a further 20 seconds.
