Description

Verfahren zur Herstellung von Kunststoffpulver für Zahnersatz, Kiefer- und Gesichtsprothesen Die Erfindung betrifft die Herstellung eiües Kunststoffpulvers, das in Verbindung mit geeigneten flüssigen Lösungsmitteln zur individuellen Fertigung von Zahn-, Kiefer- und Gesichtsprothesen vorzüglich geeignet ist. Tnsbesondere zeigt sich, daß das nach dem neuen Verfahren hergestellte Kunststoffpulver, in der bekannten, in Dentallaboratorien gebräuchlichen Weise verarbeitet, vollständig spannungs- und lunkerfreie Erzeugnisse liefert. L)adurch ist aber diese Nasse vorzüglich zur Aufnahme von metallenen Stützeinlagen, wie z. B. Stahldrahtgewelen, geeignet, da diese nur bei ganz spannungs- und lunkerfreiem Einbetten wesentlich verstärkend wirken. Die bisher bekanntgewordenen Preßmassen zeigen immer wieder, insbesondere wenn sie, z. B. bei Gaumenplatten, metallene Stützgewel)e einschließen, an Streifenbildungen (Strains) erkenntliche Spannungserscheinungen und Lunkerbildungen, die die verstärkende \Vi rkung der Stützeinlagen illusorisch machen.Process for the production of plastic powder for dentures, jaw and facial prostheses The invention relates to the production of a plastic powder, this in connection with suitable liquid solvents for individual production of dental, jaw and facial prostheses is particularly suitable. Specifically shows that the plastic powder produced by the new process, in the known, Processed in the usual way in dental laboratories, completely tension and supplies void-free products. Because of this, however, this wetness is excellent for absorption of metal support inserts, such as. B. steel wire cores, suitable because these only have a significantly reinforcing effect when the investment is completely tension-free and free of voids. the previously known molding compounds show again and again, especially when they z. B. in the case of palatal plates, metal support corrugations) e include the formation of stripes (Strains) recognizable tension phenomena and cavities that reinforce the Making the reinforcement inserts illusory.

Mit dem erfindungsgemäßen Verfahren wird ein Kunststoffpulver erzielt, das außer der besagten Spannungs- und Lunkerfreiheit und der dadurch bedingten hohen mechanischen Festigkeit noch die für die Prothetik bedeutenden Vorteile eines geringen spezifischen Gewichtes und einer hohen Säurefestigkeit mit sich bringt. With the method according to the invention, a plastic powder is achieved, that apart from the aforementioned freedom from tension and voids and the resulting high mechanical strength nor the advantages of a small one, which are important for prosthetics specific weight and a high acid resistance.

Gemäß der Erfindung werden für die Grundmasse Polymerisationsprodukte der Acrylsäure zum Ausgang genommen. Nach Zerkleinern und Vormahlen dieser Grundmasse erfolgt ein Bleichen und Trocknen an der Luft. Danach wird die Masse einer besonderen thermischen Behandlung unter- sorgen, die aus einer langsamen, 2 bis 3 Stunden währenden Aufwärmung auf 40 bis 600 und einem anschließenden Abkühlen während der gleichen Zeitspanne bis auf Zimmertemperatur (I50) besteht. Daraufhin werden die so behandelten Massen fein vermahlen, und zwar je nach dem Verwendungszweck in verschiedener Körnung. Dabei erhält das Mahlgut auch wieder je nach dem Verwendungszweck Zusätze an Farbstoffen und Mineralien, wie Marmor und Quarz in feinster Form, welche bei entsprechender Eigentönung zugleich Farbcharakter haben können, insbesondere auch Tridymit, Rosenquarz u. dgl. Mineralien. Das Ganze wird nun mit Wasser zu einem Brei verarbeitet, durchgeknetet und abfiltriert, darauf langsam auf 400 erwärmt und noch einmal durchgearbeitet, bis eine vollständige, gleichmäßige Verteilung der Stoffe erreicht ist. Die wieder langsam abgekühlte Masse zerfällt zu einem Pulver, das nach einer abermaligen Nachmahlung und Nachsiebung das fertige Produkt darstellt. According to the invention, polymerization products are used for the base material the acrylic acid taken as the exit. After crushing and pre-grinding this basic mass bleaching and air drying takes place. After that, the crowd becomes a special one thermal treatment under worries that arise from a slow, 2 up to 3 hours of warming up to 40 to 600 and a subsequent cooling persists to room temperature (150) during the same period of time. Thereupon the masses treated in this way are finely ground, depending on the intended use in different grains. The grist is also given again depending on the intended use Additions of dyes and minerals, such as marble and quartz in the finest form, which with a corresponding self-tint can also have a color character, in particular also tridymite, rose quartz and similar minerals. The whole thing now becomes one with water Processed the pulp, kneaded and filtered off, then slowly heated to 400 and worked through again until a complete, even distribution the substance is reached. The again slowly cooled mass disintegrates into a powder, which, after repeated regrinding and re-sieving, represents the finished product.

Das so erhaltene Kunststoffpulver ist in der bekannten und gebräuchlichen Weise zur Herstellung von Ersatzzähnen, von Kiefer- und Gesichtsprothesen zu verarbeiten. Dabei ergibt sich bezüglich der Gipsabdruckformen noch der besondere Vorteil, daß das bisher notwendige Erhärten der Modelle mit Wasserglaslösungen u. dgl. in Fortfall kommen kann, da das neue Kunststoffpulver bereits selbst die Zusätze enthält, die direkt auf dem Gips der Formen zu arbeiten gestatten. Wird als flüssiges Mittel zum Anmachen des nach dem beschriebenen Verfahren hergestellten Kunststoffpulvers eine rasch verdunstende Lösung von gechlorten Kohlenwasserstoffen unter Mischung mit Mineralien verwendet, so sichert das eine besondere Erleichterung bei der Herstellung der Prothesen. The plastic powder thus obtained is in the known and customary Way to manufacture replacement teeth, to process jaw and facial prostheses. With regard to the plaster cast molds, there is also the particular advantage that the previously necessary hardening of the models with water glass solutions and the like no longer exist can come because the new plastic powder itself already contains the additives that Allow working directly on the plaster of the molds. Used as a liquid asset for mixing the plastic powder produced by the method described a rapidly evaporating solution of chlorinated hydrocarbons while mixing Used with minerals, this ensures a particular ease of manufacture of the prostheses.

Wi rd das beschriebene Material, Pulver und Anreibeflüssigkeit, von dem behandelnden Zahnarzt mit den vom Antragsteller zu liefernden geeigneten antiseptischen Zusätzen gemischt, wie beispielsweise Jodoform, Thymol, Formaldehyd, so kann es auch als Wurzelfüllpaste verwendet werden, indem es im Zahn erhärtet.Will the material described, powder and grinding liquid, from the treating dentist with the appropriate antiseptic to be supplied by the applicant Mixed additives, such as iodoform, thymol, formaldehyde, can be used Can also be used as a root filling paste by hardening it in the tooth.
