Bonding Instructions for All-Porcelain Crowns
& Onlays:
Pre-appointment Preparation by the Assistant:
1. Place Rely-x porcelain
primer on the etched surface of the onlay or porcelain crown and let it dry prior
to the appointment.
2. Cut thin retraction cord (purple) enough to go
completely around the tooth
3. If there are multiple crowns, draw circles on the
tray paper for each crown or onlay and label each circle with the
appropriate tooth number.
4 For onlays only: Place the porcelain veneer curing
tip on the curing light.
5 Get out the Variolink porcelain
luting material.
6 Get out the etchant and All-Bond materials, the
Superoxol, and brushes. (We will use a red brush for the Superoxol and a
green or yellow brush for the All-Bond)
7 Get out a 3x3 paper pad and plastic mixing spatula
for the Variolink luting composite.
8. For onlays, get out the box of Vivastick sticky
sticks. Don’t remove any of the sticks from the box – just have the box
ready.
Seat the Patient:
1. Place topical anesthetic.
2. Pumice the tooth to receive crown or onlay while
you are waiting for the dentist.
Bonding procedure of All-Porcelain Crown or Onlay by the Doctor:
1. Give local anesthetic
2. Try on the porcelain crown or onlay again.
3. Get out the veneer luting composite – probably
Variolink A and B clear.
4. Place cord.
5. Brush on
Superoxol to prevent gingival bleeding.
Rinse it off and re-apply until it quits foaming.
6. Etch the tooth. Assistant mixes the A+B primer
while the dentist begins etching.
7. Swab on 5 coats of mixed A+B primer. Assistant
mixes All Bond D/E resin and Pre-Bond resin while the dentist is swabbing on
the primer. Mix a very small amount – a fraction of a drop of each.
8. Dry the primer.
9. Place mixed AllBond bonding resin on the tooth and
on the onlay or crown. Assistant can mix the Variolink while bonding resin
is being applied.
10. Place mixed Variolink on the onlay or crown. Be
sure the onlay or crown has already had the bonding resin applied before
placing the Variolink.
11. Place the onlay or crown on the tooth. Wipe off
the gross excess.
12. FOR AN ONLAY: Cure just the central part of the
onlay using the porcelain veneer curing tip. For a full crown, proceed to
step 12 – cleaning off the excess – without an initial cure.
13. Using waxed floss, clean off all the excess
luting composite.
14.Cure the onlay or crown more thoroughly.
15.Adjust occlusion, shape, and polish the crown or
onlay.
16.Final cure – one minute each on the occlusal,
buccal, and lingual surfaces.
