PRECAUTIONS:
Hydrofluoric acid is a very powerful and aggressive
chemical. It is a severe eye and tissue irritant. If
accidentally splashed into the eye, flush with copious
amounts of water for 15 minutes and seek immediate medical
attention. Hydrofluoric acid also releases a vapor that
irritates respiratory passageways. Chronic inhalation
of fumes is dangerous and can cause damage. Extreme
care must be taken to protect the patient, operator
and assistant. These individuals must wear protective
eyewear. The operator and assistant must wear protective
gloves. Rubber dam isolation must be used for intraoral
porcelain repair.
If PORCELAIN
ETCHANT comes in contact with other tissues: rinse
affected area immediately with copious amounts of water
for several minutes. Injury may result if etchant is
allowed to remain on the skin or mucosa for any length
of time.
BISCO's 4% PORCELAIN
ETCHANT has been buffered, gelled and packaged to
minimize problems, provided that it is used in accordance
with these instructions. Do not use this product until
you have thoroughly read and understood these instructions.
ETCHING ALL-CERAMIC
RESTORATIONS PRIOR TO CEMENTATION
1. Protective eyewear
and gloves must be worn by operator and assistant.
2. If the lab hasn't already etched the restoration,
apply
PORCELAIN ETCHANT to the dried internal surface
for 5-6 minutes. Care must be taken to avoid having
the etchant contact glazed porcelain surfaces since
these surfaces will lose their gloss.
NOTE: Not all ceramic systems are etchable. Contact your lab
for manufacturer's instructions.
3. Rinse with copious amounts of water to remove etchant
and air dry. The etched surface may appear dull and
frosty.
4. Apply one to two thin coats of silane, such as BIS-SILANE™ or
PORCELAIN PRIMER, with a brush to the etched internal
surface of the restoration and allow to dwell for 30
seconds. Dry with air syringe.
5. Use an adhesive
system, such as ALL-BOND 2®*, ALL-BOND 3™* or ONE-STEP®*/ONE-STEP PLUS, according to the manufacturer's instructions.
6. Continue with cementation according to the manufacturer's
instructions.
REPAIR OF ALL-CERAMIC
RESTORATIONS AND SURFACES WITH EXPOSED METAL
1. Protective eyewear
must be worn by patient, operator and assistant. Protective
gloves must be worn by operator and assistant.
2. Freshen and roughen the porcelain repair site by
using a diamond bur. (Remove any old composite remaining
from previous repairs.)
3. Isolate the area
to be etched with a rubber dam. BISCO's BARRIER GEL
should be placed where etching is not desired.
4. PRECAUTION: Confirm that syringe tip is adequately
placed and tightly attached. Test that etchant is flowing
freely from the syringe tip by expressing a small amount
onto a mixing pad. If there is resistance to flow, DO
NOT proceed. Replace tip and test flow again before
using on patient.
5. Apply
PORCELAIN ETCHANT to the dried repair site for
5-6 minutes. To evacuate hydrofluoric acid vapors, hold
evacuator tip adjacent to repair site. Monitor the etch
site throughout the entire procedure.
NOTE:
Not all ceramic systems are etchable. Contact your lab
for manufacturer's instructions.
6. Rinse with copious
amounts of water to remove etchant and air dry. The
etched surface may appear dull and frosty.
7. Apply one to
two thin coats of silane, such as BIS-SILANE or PORCELAIN
PRIMER, with a brush to the etched surface of the
restoration and allow to dwell for 30 seconds. Dry with
air syringe.
8. Use an adhesive
system, such as ALL-BOND 2, ALL-BOND 3 or ONE-STEP/ONE-STEP PLUS,
according to the manufacturer's instructions.
9. Continue with
the porcelain repair applying BISCO's OPAQUER on exposed
metal and the appropriate composite, such as ÆLITE™*
All-Purpose Body, according to the composite manufacturer's
instructions.
