Abstract

Total or partial dental prosthesis with a steel-reinforced, permanently soft lining of silicone rubber for bearing on a jaw ridge can be separated into 2 parts. The part bearing on the jaw ridge has a steel reinforcement holding the soft lining, whilst the prosthesis part has a metal support for artificial teeth, which is attached to the steel reinforcement and can be detached.

Description

The invention relates to a total or partial denture with a steel armored, lasting sturdy soft relining made of silicone rubber to rest on a jaw Comb.

Such a prosthesis is known from DE 39 11 520 A1, in which first a permanent one Soft silicone rubber lining on a steel armored support is brought and the silicone rubber is vulcanized at temperatures of approx. 200 ° C. In a second step, a prothe is used to manufacture the artificial gums plastic, in which the artificial teeth are embedded, at temperatures of approx. 100 ° C processed.  

From US 4867681 and US 4094067 such dental prostheses are known, in which the above materials in one piece in a unitary prosthesis are connected.  

The disadvantage here is that it is due to the relatively low allowable processing temperature rature of the prosthesis plastic is not possible, relining the prosthesis at higher  Clean temperatures as about 100 ° C. So the lining can be in the material tion that is capable of absorbing water or saliva to a certain extent, bacteria and fungi settle, which then because a temperature of about 100 ° C is often not sufficient to the Pro sufficiently clean these and safely kill all bacteria and fungal spores, can cause painful inflammation.

The object of the invention is to provide a generic denture that can be cleaned at temperatures well above 100 ° C, so all bacteria and certainly kill fungal spores.

The object is achieved by the features of claim 1.

Advantageous embodiments of the invention are shown in the subclaims.

Further advantages result from the following description of an off exemplary embodiment, reference being made to a drawing, in which

Fig. 1 shows a side view of a dental prosthesis in the disassembled state,

Fig. 2 shows a side view of the dental prosthesis in the assembled state,

Fig. 3 is a plan view of the dental prosthesis shows

Fig. 4 shows a cross-sectional view of the denture, in the disassembled state.

Fig. 1 shows the two parts in a side view and exploded view of a dental prosthesis according to the invention in the disassembled state, namely, a prosthesis part 1 and a mating ridge support section 2. The jaw comb support part 2 has a steel reinforcement 3 , the contour and cross-sectional shape of which is adapted to the individually given jaw comb, so that an optimal fit is ensured. The jaw-side support surface of the alveolar ridge support part 2 is seen with a permanently soft relining 4 , preferably made of silicone rubber, which is to avoid the formation of pressure points.

The associated prosthesis part 1 carries on a metal or steel support 6, the artificial gums recreated from a suitable prosthesis plastic 5 and artificial teeth embedded therein, e.g. B. plastic teeth 11 . The contour and cross-sectional shape of the steel support 6 correspond at least in the contact area of the steel reinforcement 3 , so that the two parts of the prosthesis lie against one another without play in the assembled state ( FIG. 2). The alternwei se complementary shape of the steel support 6 and the steel reinforcement 3 or at least the mutually facing surfaces of these parts is also clear from Fig. 4, which shows a cross-sectional view.

As further shown in Fig. 4 further shows, on the prosthesis part 1 or the jaw ridge part 2 each interacting anchoring or fastening means are provided, which in the example described here with holes 8 provided Ansät ze 14 a on the jaw ridge support part 2 and corresponding receiving openings 14 b in the prosthetic senteil 1 are formed are being incorporated into the prosthesis part 1 bores 7, so that a fixing of the two parts in the assembled state (Fig. 3) by means of a schiebbarer pins 9 is possible.

In Fig. 3 it is indicated how the pins 9 can be loosened again with a mandrel-like tool 10 .

Instead of the lugs and pins provided with holes, other fixing means can be used be provided to releasably connect the prosthesis parts together, such as Clamping elements or magnetic fasteners.  

According to the invention, it is now possible to clean the soft, water-absorbent and therefore possibly contaminated with bacteria or fungal spores relining 4 at temperatures significantly above 100 ° C. without simultaneously having to expose the less temperature-stable prosthesis plastic 5 to the same cleaning temperature, namely by placing the prosthesis in front of the Cleaning is disassembled and the two parts, prosthesis part 1 and jaw comb support part 2 , are each cleaned for themselves, as it corresponds to the respective need and material strength. Here, the prosthesis part 1 does not need to be particularly heated (sterilized), since all materials (metal, prosthesis plastic and teeth) are practically not water-absorbent, so that a simple surface cleaning with conventional means is sufficient here.
