Description
Kunststoff Zusatz zum Patent 656 642 Verwendung von Polymerisationsprodukten von Homologen der Acrylsäure oder von funktionellen Derivaten dieser Homologen für die Herstellung zahntechnischer Artikel. Plastic addition to patent 656 642. Use of polymerisation products of homologues of acrylic acid or of functional derivatives of these homologues for the manufacture of dental technology articles.
Gegenstand des Hauptpatents 656 642 ist die Verwendung von Polymerisationsprodukten von Homologen der Acrylsäure oder von funktionellen Derivaten dieser Homologen oder von Mischungen vorgenannter Polymerisate mit oder Zähne organische Zusatastoffe für die Herstellung von Kunststoffen. The subject of the main patent 656 642 is the use of polymerization products of homologues of acrylic acid or of functional derivatives of these homologues or of mixtures of the aforementioned polymers with or teeth organic additives for the manufacture of plastics.
Es wurde gefunden, daß die gemäß Hauptpatent als Kunststoffe zu verwendendenPolymerisate bzw. polymerisathaltigen Gemische ausgezeichnete Eignung besitzen für die Herstellung von zahntechnischen Artikeln. It has been found that the polymers to be used as plastics according to the main patent or polymer-containing mixtures have excellent suitability for production of dental articles.
Für diesen Zweck kommen insbesondere Polymerisate von Estern der Methacrylsäure in Betracht, welche nach üblichen Methoden, z. B. durch Erwärmen der zu polymerisierenden Ausgangsstoffe, zweckmäßig in Gegenwart von Polymerisationsbeschleunigern erhalten werden können. Mit besonderem Vorteil wird die Polymerisation in Gegenwart von Sauerstoff oder sauerstoffabgebenden Substanzen, wie Wasserstoffsuperoxyd, organischen Peroxyden, Perborat usw., durchgeführt. Als Zusatzstoffe kommen die im Hauptpatent genannten, insbesondere Weichmachungsmittel in Betracht. Als Weichmacher können u. a. auch polymerisierte Ester der Acrylsäure oder ihrer Homologen, insbesondere solche mit höher molekularen Alkylresten verwendet werden. In particular, polymers of esters are used for this purpose Methacrylic acid into consideration, which by conventional methods, for. B. by heating of the starting materials to be polymerized, expediently in the presence of polymerization accelerators can be obtained. The polymerization in the presence is particularly advantageous of oxygen or oxygen-releasing substances such as hydrogen peroxide, organic Peroxides, perborate, etc. carried out. The additives in the main patent are used as additives mentioned, in particular plasticizers. Can be used as a plasticizer i.a. also polymerized esters of acrylic acid or its homologues, in particular those with higher molecular weight alkyl radicals can be used.
Die Verarbeitung der Polymerisate bzw. der polymerisathaltigen Gemische auf zahntechnische Artikel, wie Zahnprothesen, künstliche Gaumen, künstliche Zähne u. dgl., kann nach üblichen Methoden der Verarbeitung von Kunstharzen z. B. durch Formgebung der z. B. thermisch erweichten Produkte ererfolgen. The processing of the polymers or the polymer-containing mixtures on dental technology articles such as dentures, artificial palates, artificial teeth u. The like., According to conventional methods of processing synthetic resins z. B. by Shaping the z. B. thermally softened products.
Beispiele I. 95 Teile Methylpolymethacrylat werden mit 5 Teilen Phtlulsäuremethylglvcolester vermischt und eine geringe Menge einer Farbstoffmischung aus weiß, rot und blau zugesetzt, welche befähigt ist, der Masse eine zahnfleischfarbige Tönung zu gehen. Die Mischung kann durch Maßnahmen, wie thermische Erweichung, z. B. bei Temperaturen von 150 bis I800 C, und Pressen unter Druck in gewünschte zahntechnische Artikel, z. B. Examples I. 95 parts of methyl polymethacrylate are mixed with 5 parts of methyl glycol ester mixed and a small amount of a dye mixture of white, red and blue added, which is able to give the mass a gum-colored tint. The mixture can be made by measures such as thermal softening, e.g. B. at temperatures from 150 to I800 C, and pressing under pressure into the desired dental technology articles, z. B.
Zstbnprothesen, verarbeitet werden. Zstbnprothesen, processed.
2. 95 Teile Methylpolymethacrylat werden ;mit 5. Teilen Phthalsäuremethylglycolester unter Zusatz von Farbkörpern, welche befähight sind, der Masse ein weißlich-gelbes naturzahnartiges Aussehen zu geben, ver-* mischt. Aus der thermisch erweichten X schwung werden durch Verpressung künstli@@e Zähne hergestellt. 2. 95 parts of methyl polymethacrylate become with 5. parts of phthalic acid methyl glycol ester under Addition of color bodies, which are capable of giving the mass a whitish-yellow natural tooth-like appearance To give appearance, mixed. From the thermally softened X swing become through Pressing artificial teeth produced.
3. Eine Mischung von 85 Teilen Methylmethacrylat und 15 Teilen Buthylacrylat wird unter Zugabe von Benzoylsuperoxyd und geringen Farbstoffmengen polymerisiert. Der Polymerisationsvorgang wird derart durchgeführt, daß Kunststoffplatten von gewünschten Abmessungen, z. B. 8 bis 13 mm Kunststoffplatten eralten werden. Derartige Platten werden nach üblichen Methoden zur Herstellung von Zahnprothesen verwandt. 3. A mixture of 85 parts of methyl methacrylate and 15 parts of buthylacrylate is polymerized with the addition of benzoyl peroxide and small amounts of dye. The polymerization process is carried out so that plastic sheets of desired Dimensions, e.g. B. 8 to 13 mm plastic sheets can be obtained. Such plates are used according to the usual methods for the production of dentures.
