Abstract: A dispensing station according to the present invention includes a pneumatic or hydraulic cylinder, the plunger of which forces prepackaged materials from two tubes or a dual tube housing through a dispensing tube. The dual housing keeps the A and B materials separate until they are forced out by pneumatic cylinder. A knob adjusts the air pressure to pneumatic cylinder in response to a foot pedal. Alternatively, time and pressure can programmed into a device for metering materials. The device for metering materials can be set to adjust the pressure from pneumatic cylinder by outlet tubes and meters dispensing of the combined A and B materials through other tubes. The combined materials are dispensed onto a work product, such as a dental model which rests on a base support, for producing a dental device. A pole is vertically mounted on the base support. The combined unit comprising pneumatic or hydraulic cylinder, two tubes or a dual tube housing and associated structure is adjustably mounted on the pole.

Abstract: A method for making a dental appliance is disclosed, including affixing a first blank piece of material to a second blank piece of material forming a combined blank. The first blank piece of material is substantially softer than the second blank piece of material. The combined blank is then placed over a dental cast with the first blank piece of material faces the dental cast, and a dental appliance is formed by using a thermal form suck-down of the combined blank over the dental cast with the first blank piece of material in contact with the teeth of the dental cast. Finally, the dental appliance is removed from the dental cast. The dental appliance can be trimmed while it is on the dental cast or after it is removed.
