Pellet Use
A five-pound container of zinc pellets is supplied with each MiniSTAR S. Pellets are used to prevent the thermal-plastic
materials from stretching over areas of the model that are not part of the appliance design. Stainless steel pellets (010-099)
are also available. It is important that pellets are
chamber for forming pressure and may cause damage to the cup's rim if compressed by the pressure chamber. Use of mat-
erials other than the manufacturer's recommended pellets may result in machine malfunction and could void the warranty.
Work models are placed in cylindrical pellets:
•
to support the model so that the occlusal-incisal plane is as level as possible with the rim of the cup
•
to prevent the material from forming on the facial surfaces of the teeth, making it hard to remove the appliance
from the work model
•
to prevent heated material from melting the wax supporting the wires on facial areas
•
to allow air to pass through the pellets as the material is forming over the model, preventing back pressure
Empty cup or reduce the pellet line to the half-way level
(white arrow).
Make sure the inner lip of the cup is
clean.
Place the outer ring of the platform on the inner
lip of the pellet cup with the flat platform surface on top
(white line).
To remove the platform, use the
MiniSTAR S Brush with Magnet
(016-021). Engage the tip and
lift up.
Remove model bubbles and detail the oral anatomy with a
laboratory knife. Fill holes in the model with a quick-setting
stone.
When referencing the model to the platform, make sure the
base of the model is reduced flat, parallel to the occlusal
surface. In some cases, the base is removed creating a flat
horseshoe model to eliminate excessive material thinning.
For some materials, a liquid separating foil is applied to
allow for easy removal of formed material.
Position the model on the platform, referencing the heel
toward the material in the pressure chamber, and incisor
segment near center of the platform, if possible.
NOT
on the platform. Pellets left on the cup/rim will prevent locking of the
