Fabrication Of A New Denture Or Partial
Denture And CT Scanning Appliance
(continued)
5.
CLINICIAN
Place the wax try-in(s) in the mouth. Verify the occlusion, aesthetics
and phonetics. Make any adjustments necessary. If major adjust-
ments are necessary, make a new interocclusal registration and
return to the laboratory for a new set-up and wax try-in.
6.
LABORATORY
Wax the denture for the arch in which implants will be placed for
processing, and flask it. Separate the flask, and boil away the wax.
Process, finish and polish the denture. Using a denture duplication
flask, mix the duplication material and place it into one side of the
flask. Place the patient’s existing denture into the material with the
soft-tissue side down. Allow the duplication material to set per the
manufacturer’s instructions. Apply a separator to the surface. Mix the
duplication material and place it into the other side of the flask and
close the flask over the denture. Allow the duplication material to
set. Separate the flask and remove the denture.
7.
Create a mixture of 30% barium sulfate and cold-cure acrylic resin.
Pour the mixture into the tooth areas only. Allow the acrylic resin
to set per the manufacturer’s instructions. Create a mixture of 10%
barium sulfate and cold-cure acrylic resin. Pour the mixture into the
flask. Close the flask tightly. Allow the acrylic resin to set.
8.
Remove the CT scanning appliance from the flask, finish and polish.
Place the appliance on the cast. Place the cast on the articulator and
make an interocclusal registration. The scanning appliance is returned
to the clinician for the CT scan and the occlusal registration is set
aside for later use.
