Abstract
ABSTRACT OF THE DISCLOSURE
There is disclosed a dental application fluid for prosthetic work that is a directly applicable fluid, which, in contrast to known silicon-based compounds, requires no prior preparation by means of a catalyst. The product is non-viscous and may be applied and distributed without difficulty by means of forceps and a ball of cotton. The application fluid drys fast;
the drying time equals only about 5 to 10 seconds and can even be shortened with the use of a hand blower. The application fluid adheres to all materials which are used in the dental profession including tooth materials. The application fluid thereby allows an unusually exact determination of pressure and contact points.
The marking of contacts and early contacts is very distinct. The application fluid is easily and economically measured out, because of its non-viscous consistency and composition. A significantly greater number of crown coatings is therefore achieved in contrast to occlusion sprays (improvement equals about 350%). The fluid is neither toxic nor does it irritate the pulp. After use, the appli-cation fluid is quickly and well-removed from the teeth, crowns and the like with a solvent fluid. String formation and clumping, because of contact with saliva, do not occur during use. Such a dental application fluid is directly applicable, non-viscous fast drying and comprises: (a) 0.5 to 10 parts by weight of an organic polymer adhesive, (b) 35 to 65 parts by weight of a massive component, (c) 0.1 to 10 parts by weight of a coloured pigment and (d) 30 to 70 parts by weight of a physiologically harmless alcoholic fluid, components (a), (b) and (c) being dis-solved or respectively dispersed in fluid (d).

Thick films are used for the rough formation of occlusion points and thinner films are used for finely shaping the occlusion points and articulation points ( i . e ., those points in con-tact during lateral and advancing movements of the jaw). Contact points may be determined and inspected by biting down on the teeth and by means of articulation movements. However, occlusion papers of this kind are unsuited for the production and inspection of prosthetic works.
Furthermore, so-called occlusion WAXeS, available in the form of small plates, are known and have been proposed for the bite (abduction), that is, the occlusion.

The granularity of the powder is between 10 and 20 micrometers.

For this reason, the pressure points may 2 5 only be very inaccurately determined because the powder already loses its adhesiveness after the slightest contact, and is therefore only actually usable with extremely early contacts. A further disadvantage is that the powder becomes stringy and forms lumpy deposits after the unavoidable contect with saliva, and is thereafter unusable. The occlusion spray is not particularly well removed with water. The powder gives off much dust when applied, so that fingers, hands, and even the local environment are heavily con-taminated .
