1- Analyse the duplicate model on the articulator with the relative antagonist model.
2- Insulate the working model with DENTAL D Photocurable Lacquer and then harden the lacquer in the oven.
3- Position the teeth as required; for greater mechanical adhesion of the teeth, we recommend making 0.8 – 1.5 mm mesial to distal holes through the cingulum of the tooth in addition to the central hole.
4- Cast the wax model.
5- Position the model with the cast in the lower part of the flask without enclosing the mount and flange, using Class III or IV plaster.
6- Position three injection sprues
using 4.5/5 mm wax together towards the injection inlet of the flask, taking care to complete seal the inlet.
7- Insulate the plaster; close the flask before continuing by bolting the two parts together.
8- Fill the upper part of the flask with plaster (Class III or IV) until it is a couple of millimetres below the maximum marker on the flask.
9- Once the stone has set unscrew the nuts and remove any and all wax residue by using steam or hot water.
10- Insulate the working model with DENTAL D Photocurable Lacquer and the relative part of the antagonist cast.
