DIVESTING AND
DRY TRIMMING
Divesting: Put the blade tip of a
plaster knife between the impres-
sion and the plaster. The model
is lifted out of the impression
by turning the blade. Therefore,
the back of the blade rests on
the tray rim, and the tip of the
plate levers the model out of the
impression.
!
IMPORTANT:
Do not exceed the maxi-
mal divesting time of 35 min
since otherwise irreparable
dimensional deviations occur
due to the plaster expansion,
thus resulting in a high risk of
breaking the dental arch.
O P E R AT I N G I N S T R U C T I O N S
Place the model flat in your hand
with the split retention looking
downward, hit it with a hammer
on the dorsal area of the plate
until the dental arch comes off.
Then, dry trim the dental arch in
the vestibular and palatal area
with the Multitrim unit (115800).
As an alternative to dry trimming
and for finishing purposes, a
handpiece may be used furnished
with mandrel (815300) and arbor
band - grit 120 (815330).
