Impression of the Peinabdruok mass is created.

The painful impression material creates an additional one in the preprint Space requirement, the expansion of the preprint mass and tension in the same when making painful impressions has the consequence. After removing the pre-impression material with created painful impression from the patient's mouth there is often a slight regression of the expanded preprint mass, which in the process creates the painful impression impaired in its accuracy.

The task of the innovation is to create a device that forms and while avoiding the previous shortcomings Enables exact size making of impressions for the dental prosthesis.

The device should be simple and cost-saving and easy to use, and should be made by the dentist allow individual impressions with optimal accuracy.

According to the invention there is an impression material plate for use in the manufacture of dentures by a deformable one and shape-retaining impression layer, a so-called placeholder layer, marked with a U-shaped basic shape, in which the impression layer is preferably of a flat, thin-walled one and pliable plate is formed from a reinforced layer.

Advantageous further developments result from the other subclaims.

The deformable placeholder layer 12 is used to create a preprint 13, which is uniformly enlarged in its shape, in the preprint compound 11, in that the placeholder layer 12, which can be molded onto the teeth 1h and / or the jaw 15, fits positively into the preprint compound 11 and out of the preprint compound

11 can be removed after it has set,

so that the space "X" (FIG. 5) previously occupied by the placeholder layer 12 becomes free and that which is to be introduced into the preprint 13 Fine casting compound 16 for the creation of a final impression 17 takes up. The from the placeholder layer 12 in Additional space "X" created in advance 13 corresponds at least almost to the thickness of the placeholder layer 12, and this Space "X" takes, while avoiding tension or additional deformation of the preprint compound 11 during the production of the final Imprint 17 on the fine impression compound 16; This space "X" means that the preprint 13 is enlarged in terms of shape executed.

The placeholder layer 12 is made from a wax and, through a reinforcing layer 18, is made from a fabric made of plastic Cotton or another suitable material stabilized in shape.

As shown in Fig. 3 of the drawing, the reinforcement layer 18 is embedded in the wax layer 12 so that this Layer 18 lies between two superimposed, interlocking wax layers.

In a further embodiment, not shown, the reinforcement layer is 18 on one side of the wax layer 12, namely on this or below it. The placeholder layer

12 (wax layer and reinforcement layer 18 together) has a thickness of, for example, va. 1 mm to about 2 mm, preferably approx. 1.5 mm.

The placeholder layer 12 can also be made of a readily deformable material and form shape-retaining plastic.

The placeholder layer 12 has a U-shaped basic shape and its two U-legs, which diverge from one another according to the shape of the jaw, as well as these two IT legs ver binding U-webs have approximately the same width and sand in the size of the width so that the layer 12 is flawless can be shaped over the teeth 14 and jaw 15.

When the placeholder 12 is used, the U-legs extend in the area of the molars and the U-web in the area of the Front teeth (cutting teeth).

The preprint compound 11 and the painterial impression compound 16 consist of a plastic compound, preferably a silicone compound.

The known impression spoon serving as a carrier and printing part Io has a U-like basic shape adapted to the shape of the jaw and the U basic shape is in cross-section for the receptacle and Fixing the position of the preprint compound 11 is designed like a channel. A handle part (handle) loa is provided on the spoon Io and A large number of holes can be made in the spoon Io for anchoring the pre-impression material.

The impression spoon Io with handle loa consists of a corrosion-resistant one Metal, such as surface-refined (chrome-plated) steel.

The production of an impression with the device according to the invention happens as follows:

The placeholder layer 12, which is inherently flat in the starting position, is applied by hand to the teeth 14 and the jaw 15 of the patient integrally formed, this layer 12 due to its suppleness (due to the reinforced wax layer) can be adapted very easily and precisely to the shape of the tooth and jaw.

The placeholder 12 is with its U-opening first in the The patient's mouth is inserted, placed on or under the teeth or the jaw, and then deformed over it by hand.

The molded placeholder layer 12 then remains in its deformed design on (on) the teeth 14 and the jaw 15. Then the impression spoon Io with its pasty preprint compound applied in a thick layer is made 21 pressed onto the placeholder layer 12, so that a preprint 13 results in the preprint compound 11, which is in the The size and shape of the deformed placeholder layer 12 corresponds; the deformed placeholder layer 12 is thus in a form-fitting manner in the preprint compound 11. After the preprint compound 11 has set (solidified), it is covered with the placeholder layer 12 withdrawn from teeth 14 and jaw 15 and from the The patient's mouth is removed.

Thereafter, the placeholder layer 12 is detached from the preprint compound 11, which is achieved by simply lifting the layer 12 is possible because this is not glued to the preprint compound 11.

The placeholder layer 12 has in the preprint compound 11 a preprint that is enlarged by the thickness of the placeholder layer 12 13 created.

After the placeholder layer 12 has been detached, the pulpy fine impression compound 16 is introduced into the preliminary impression 13, preferably poured in, and then the spoon Io with the preprint compound 11 and the fine impression compound located therein 16 again pressed onto the teeth 14 and the jaw 15 of the patient, so that now by precisely adjusting the fine impression material 16 on the teeth 14 and the jaw 15, the final impression 17 is made. The fine impression compound 16 increases the formation of the teeth 14 and the jaw 15 now the previous occupied by the placeholder layer 12 and additionally created by this space "X", so that when they are deformed no significant pressure is exerted on the preprint compound 11, which would lead to tension and additional deformation
