## Abstract

An improved dough-like filler material for use in dental and orthodontic modelling and the manufacturing methods that may be used to produce such improved dough-like filler material.

## Claims

### Claim 1

A method for producing and finishing a plaster dental model comprising the steps of:
making a dental impression using an impression material-filled impression tray, said impression tray having a void for accommodating a patient's tongue;
occluding said void with a dough-like filler material that is made by the following steps:
mixing together the following ingredients:
300-370 grams flour;
295-360 grams salt;
53-65 grams cream of tartar;
55-67 grams cooking oil;
424-518 grams water;
spreading the mixed ingredients on a pan and cooking the ingredients at 130° C. to 140° C. for 6 minutes to 10 minutes;
kneading the ingredients together with 7.4 mL to 9 mL of aromatic oil to form an intermediate material;
spreading the intermediate material onto a pan and setting that pan on a cooling rack to cool for at least 2.5 hours so as to become the completed dough-like filler material;
packaging the dough-like filler material in one or more containers.

### Claim 2 (depends on 1)

The method of claim 1 wherein the water is distilled prior to use.

### Claim 3 (depends on 1)

The method of claim 1 wherein the cooking is done within an oven that distributes heat evenly within the oven.

### Claim 4 (depends on 1)

The method of claim 1 wherein the packaging step is accomplished using a packing jig such that:
the packing jig is filled to its top with the dough-like filler material;
multiple open volumetric forms are inserted into the dough-like filler material within the packing jig so that portions of the dough-like filler material will be located within at least a part of the internal volume of the volumetric forms;
the packing jig is removed;
excess dough-like filler material is removed from the outside of the volumetric forms;
the portions of the dough-like filler material contained within the volumetric forms are released from the volumetric forms and are then respectively packaged in individual containers.
