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
