Crown Cementation
- Cementation pouch, or basic, +hemostat, spatula, curet
and articulating paper holder
- Bur bloc, high and slow-speed handpieces (not opened)
- 3-way syringes (2), saliva and high volume (if
necessary) suctions, 2-3 cotton rolls, 1 2x2
- Cut a piece of dental floss and tie two knots in one
end
- Ketac or temp bond cement
- If doctor is
not ready, remove temporary crown using hemostat.
Twist and wriggle the crown a little bit, gradually increase force,
and luxate occlusally
- Remove
cement from the tooth with explorer and clean the tooth with 3-way syringe
- If the
patient feels very sensitive to air or water, load syringe with needle and
Mepivacaine (light) or
Xylocaine (red)
- Try in
permanent crown
- Check bite
with articulation paper
- Check
proximal contact by passing dental floss to doctor.
Help doctor to hold the crown while floss is being used
- Help doctor
suction. Pass cotton roll for
isolation. After the doctor confirms
the fitness of the crown, pass a 2x2.
The crown will be dried with air by doctor
- Rinse the
tooth and suction if necessary.
- Only after
you receive the dried crown, can you start to mix Ketac.
Apply Ketac to the inner surface of the crown, particularly margin
- Hold the
crown on the mesial and distal contact surfaces (usually flat surfaces) so
that when you pass it to doctor, he can hold it on the buccal and lingual
surfaces
- Pass a
cotton roll or bite sloth (white) for seating
- The most
important thing for you to do during the crown cementation is TO PASS THE
KNOT-TIED DENTAL FLOSS TO DOCTOR NO MATTER WHETHER HE FORGETS OR NOT
IMMEDIATELY AFTER THE CROWN IS SEATED.
The doctor uses the floss to remove extra cement between the teeth
before the cement completely sets.
If we forget this step, we will ruin our whole day.
It is extremely difficult to remove cement between the teeth when it
sets
- After this
important step and bite check, you may proceed to remove excess cement.
