Material Heating Process

Select an appropriate disc of material specific

to the appliance being fabricated. Place a

disc of material on the gasket of the pressure

chamber. Position the clamping frame over

the material, so that the bayonet clamps slip

under the bevel of the locking device on the

sides of the chamber. Tighten by turning the

handle clockwise (do not over tighten).

For example, when constructing an orthodontic

retainer, the pellets are placed against the

occlusal-incisal margin to cover the wax holding

the wires facially. The pellets act as an insulator

when the heated material is formed.

Improper packing of a model (shown at left)

can cause a blowout, air leak or machine

malfunction. It is important that there is no

sudden drop of the pellet margin at the inner cup

wall or that the model is not positioned too high

or low within the cup. This allows the material

to be overstretched, thinning it to where a hole is

created and air blows through.

In some instances, an air leak could cause

inferior material adaptation that can result in a

poorly fitted appliance.

Models mounted to articulator plates should be

splitcast. If the model cannot be removed from

the mounting, the pellet level will need to be at a

slight incline; to appliance termination areas.
