Pencil line can be seen
through the wax sheet to
help you cut it to size
Cut and shape a length of
strengthening wire to fit 5mm
inside the pindam,
terminating 5mm short of the post-
dam

Run a blunt blade along the pindam to cut the wax up
to and into the prepared groove
Any areas that are short of wax should be filled with molten modelling

The central incisor stands vertical or at right angles to the

Artificial replacement teeth are supplied on separate cards of anteriors and posteriors of an appropriate shape for the case
that is being made
Tooth mould code
Tooth shade code

The buccal face of the tooth should be
angled to reflect the neighbouring central
incisor

The lateral incisor is placed but remember to raise it off the occlusal
plane by 1mm
