ia— the / jjo rather part of the Eüvett will be a disc
or the cover is placed on which the punch of a simple press is allowed to act, whereby one part of the cuvette with the investment material is pressed off from the other part of the cuvette and detached. After releasing one part of the cuvette, the lower part of the cuvette that has been pressed down and is still connected to the investment is rotated
and placed with its approaches on the legs of the bracket, whereupon the lid into the hole of the cuvette part
inserted and the pressing process is repeated, whereby
the investment is also pressed out of the lower part of the flask. In this way, the entire investment material with the prosthesis is removed from the flask, which is divested as usual.

Through this training, the investment from the
The cuvette is removed without damaging the cuvette or the prosthesis in the investment, which means that the cuvette can be used any number of times.

In the drawing, such a cuvette is shown in an embodiment, namely shows:

Fig. 1 is a plan view before the pressing process and
2 shows a vertical cross section according to
Line AB of Fig. 1.

The cuvette consists in a known manner of the upper part a and the lower part b, which by guide pins g
easily detachable ^ are connected to each other. The leadership

Pins g are fastened in the upper part of the cuvette and are: ■ guided in bores in the lower part of the cuvette. According to the invention are. the upper and lower parts of the cuvette a and b are provided with extensions c and d on the bases, of which the extensions d are offset from the extensions c. A U-shaped metal bracket n is needed to loosen the cuvette, on whose leg o the upper cuvette part a with its attachments c is placed. After loosening the cuvette parts a and b and pressing the investment ρ out of the upper cuvette part a with the ram m, the lower cuvette part b is rotated and placed with its attachments d on the legs ο of the bracket n to press out the investment ρ. The cuvette is also provided with drainage channels i in a known manner. ■ In order to carry out the pressing processes, the cover 1 (g & a, on which the punch m of the press acts, is now placed on itf ^ SSyvf f.

The embedding takes place in a known manner as follows: The model is placed in the lower part b, as in the case of plastics processing common, wrongly embedded. After the isolation, the upper part a is put on and the two conical Locking bolt h inserted. Then the

Cast counter-cast. After the counter-casting has hardened, it is removed; the locking bolt h by lightly tapping it with a hammer. The cuvette is boiled to remove the wax and boiled as usual. In the prepared ones Flask halves provided with drainage channels i are now filled with plastic according to the instructions, whereby »© Fill the holes k of the cuvette parts -a, b with the plastic compound. The cuvette is now closed

and pressed in the press. The locking bolts are then inserted and lightly tightened with a horn hammer.

After the cuvette has cooled down completely, remove the locking bolts h by knocking them gently First place the cuvette with the extensions c on the legs ο of the bracket η and on the filling of the hole k The lid 1 is placed on the cuvette and the investment ρ is pressed out by means of the stamp 'in the press, whereby the cuvette opens. This pushes the investment ρ out of the upper part of the cuvette a, whereby the lower part of the cuvette b together with the investment material ρ still in it is pressed downwards will. The same process is repeated with the other cuvette part b. After the empty cuvette part a is removed, the lower cuvette part b, with the investment material still in it, is removed from the bracket η taken out and rotated and set with its lugs d on the bracket η and after the disc on the Filling of the hole k is placed, the investment ρ is pressed out by means of the punch m.

In this way, the entire investment ρ is retained in one block with the prosthesis. Using a G-ip saw etc. is now divested as known.

The shape of the cuvette a, b can be any.

Claims (2)

Claims; 1. cuvette for dental purposes, especially for plastics, characterized in that the cuvette (a, b) is designed in such a way that the cuvette parts (a, b) open in the unlocked state when closed Racks of any kind can be set up in such a way that the investment material (p) is first pressed out of the upper cuvette part (a) by means of a press plunger (m) The cuvette opens and the lower part of the cuvette (b) is placed on the rack and the pressing process is repeated, whereby the entire investment material (p) is in one block with the prosthesis is released. 2. cuvette for dental purposes according to claim 1, characterized in that the cuvette parts (a, l?) are provided with mutually offset projections (c, d), which when loosening the investment (p) and the cuvette parts (a, b) placed one after the other on the legs (o) of a U-shaped & n bracket (n) verden, whereby a lid (1) is placed on the fillings of the holes (k) of the cuvette parts (a, b), on which the otempel (α) of a press acts so strongly that 3 divide the investment (p) from the Kiivet th (a, b) is pushed out.
