1.) ^ Description

Die model former.

The invention relates to a stump model former of the simplest manufacture in dental technology of die models for copper ring impressions, using various types of model pens.

The sensible construction of this die model former enables the production of die models from copper ring impressions with the corresponding die base and metal or plastic pins in one operation. It is of no importance which die material or which metal or plastic pins are used.

It is known that to meet these needs one can either use paper or Wax a cuff around each individual copper ring, adapt it individually and wax it in place had to be poured out before the copper ring could be poured. There is also one made of rubber-elastic Material existing stump former, which only the production of whole and voluminous stump models from plaster-like or other types of mass allows.

All previous procedures are cumbersome and time consuming. In addition, the known per se allows Die formers do not use the most common model pens today Metal (dowel pins).

The invention is therefore based on the object of significantly simplifying the production of stump models and yet all variants with regard to the model pins to be used made of metal or To enable plastic and also to achieve a stump base at the same time.

According to the invention, this object is achieved by that the stump model former is made of a silicone or rubber-like compound, and therefore does not require any isolation from any stump material. Because of its soft consistency all shapes of copper rings can be easily inserted into the fix the die model former, and later the remove finished die models just as easily.

In order to meet all requirements in the production of the die model, there are recesses Provided by all copper ring sizes, so that one can use a stump model shaper for all Cases.

The external shape of the stump model former can have any geometric design.

An embodiment of the invention in a round shape is shown in the drawing and is Described in more detail below: Show it

Fig. 1 top of the stump model former, where 1 represents the openings for the different copper ring sizes.

Fig. 2 underside of the stump model former. The bar 2 and edge bar 3 is used to stabilize the stability of the elastic Material of the die model former and also enables the copper rings to be inserted at different heights from below, without thereby preventing the former from resting smoothly and horizontally on the table top.

The advantages achieved with the invention are in particular that

1. it is impossible for the copper rings to fall over,

2. Any number of copper ring impressions of different sizes can be easily poured together.

3. by simply inserting the copper rings from below into the die model former Fixation of the same is achieved,

4. The pouring of the fixed copper ring impressions it is also possible to use a vibrator,

5. All die materials can be used,

6. all types of model pen can be used,

7. Depending on the depth of the insertion of the copper rings from below, a stump model base of variable height is created as desired and thus all these advantages can be achieved in one operation.
