This section explains how to create dentures with this kit. Room-temperature polymerizing resin or heated polymerizing resin
may be used.
There are two methods for creating dentures: the denture base cutting method in which the resin is polymerized before the
denture base is cut and the articial teeth are a󱐰xed and the complete denture (full denture) cutting method in which the
mold for the articial teeth is cut and arranged and the resin is polymerized before the complete denture (full denture) is cut.
The work procedure varies depending on the resin and method used.

L Place the silicone stand and the FX in the pressure pot.
Usage Method
14

M Check the pressure pot's water level and temperature.
• Add water until approximately half the silicone stand is submerged.
• Heat the water until its temperature is between 20°C and 30°C (68°F and 86°F).
N Apply pressure for approximately 60 minutes.
• After applying pressure, open the lid and check that there is no liquid on the resin surface.
• This time is merely a guideline. Set the time required for the heated polymerizing resin being used to turn rub-
bery.
O Perform the pre-polymerization.
Gradually increase the water temperature to 65°C (149°F), and then perform pressurized and heated polymerization at 65
°C (149°F) for 90 to 120 minutes.
