Description
Verfahren zum Herstellen von Basisplatten zum Aufbau zahntechnischer Wachsmodelle Zum Herstellen von Basisplatten für den Aufbau zahntechnischer 'Wachsmodelle hat man bisher meist Schellack benutzt, dessen Ersatz durch einen im Inland herstellbaren Werkstoff erwünscht ist.Process for the production of base plates for the construction of dental technology Wax models For the production of base plates for the construction of dental wax models So far, shellac has mostly been used, and its replacement by one that can be produced domestically Material is desired.
Es ist bekannt, künstliche Gebisse aus Polystyrol oder polymerisierten Styrolderivaten, auch unter Zusatz von Gelatiniermitteln, hochsiedenden Lösungsmitteln und organischen Füllstoffen herzustellen. Auch- die Herstellung geformter Gegenstände aus thermoplastischen Polymerisatkunstharzen unter Zusatz von festen Weichmachern, z. B. Kampfer, ist bekannt.It is known to have artificial dentures made of polystyrene or polymerized Styrene derivatives, also with the addition of gelatinizing agents, high-boiling solvents and to produce organic fillers. Also- the manufacture of shaped objects made of thermoplastic polymer resins with the addition of solid plasticizers, z. B. camphor is known.
Die Erfindung besteht darin, daß man zum Herstellen der Basisplatten einen thermoplastischen Polymerisatkunststoff, z. B. Polystyrol, mit einem aus künstlichem oder natürlichem Wachs bestehenden Weichmacher erhitzt, mischt und das Gemisch langsam erkalten läßt.The invention consists in that one for the manufacture of the base plates a thermoplastic polymer, e.g. B. polystyrene, with one made of artificial or natural wax existing plasticizer is heated, mixes and the mixture slowly lets it cool down.
Unter Polymerisatkunststoffen sind Polymerisate von Äthylenverbindungen mit einer endständigen Methy lengruppe zu verstehen, z. B. Polystyrol, Polyvinylchlorid; Polyvinylacetat. Auch Polymerisatgemisch und Mischpolymerisate sind verwendbar. Während die Polymerisatkunststoffe Molekulargewichte über ioooo besitzen, eignen sich als feste Zusatzstoffe natürliche oder künstliche Wachse mit einem Molekulargewicht von 15o bis iooo.Under polymer plastics are polymers of ethylene compounds to understand lengruppe with a terminal methy, z. B. polystyrene, polyvinyl chloride; Polyvinyl acetate. Polymer mixtures and copolymers can also be used. While the polymer plastics have molecular weights of over 100,000, they are suitable Solid additives natural or artificial waxes with a molecular weight from 15o to iooo.
Die Verwendung von künstlichem oder natürlichem Wachs (iii Mengen von 5 bis 5o111,) als Weichmacher hat gegenüber von anderen festen Weichmachern, z. B. Kampfer, den Vorteil, däß das Gefüge des Werkstoffes gleichförmiger ist, weil z. B. Kristallbildung beim Erkalten des Weichmachers vermieden wird.The use of artificial or natural wax (iii quantities from 5 to 5o111,) as a plasticizer compared to other solid plasticizers, z. B. camphor, the advantage that the structure of the material is more uniform because z. B. Crystallization is avoided when the plasticizer cools.
Das langsame Kühlen des heißen Gemisches nach seiner Herstellung ist notwendig, damit ein Schrumpfen beim Wiedererwärmen vermieden wird.The slow cooling of the hot mixture after it is made is necessary to avoid shrinkage when reheating.
Man kann die Mischungen zusätzlich mit Füllstoffen, Farbstoffen o. dgl. versehen, doch bieten gerade füllstofffreie Mischungen den Vorteil, daß die Basisplatten im Gegensatz zu denen aus Schellack durchsichtig sind, was das Arbeiten auf den Gipsabdrücken erleichtert. .. B e i s p i e 1: 17 Teile des unter dem Namen Weichmacher N bekannten Trichlornaphthalins werden geschmolzen und in 83 Teile Polystyrol. (Molekulargewicht 10 000 bis 50000) eingeknetet. Die Masse wird zu großen Blökken erstarren gelassen, die zu Scheiben geschnitten werden. Aus den Scheiben stanzt man Basisplatten der bekannten Form aus. Die Platten werden beim Erhitzen sehr geschmeidig, ohne merklich zu kleben oder zu schrumpfen.The mixtures can also be provided with fillers, dyes or the like, but precisely filler-free mixtures offer the advantage that, in contrast to those made of shellac, the base plates are transparent, which makes it easier to work on the plaster casts. .. Example 1: 1 7 parts of the trichloronaphthalene known under the name plasticizer N are melted and converted into 83 parts of polystyrene. (Molecular weight 10,000 to 50,000) kneaded. The mass is left to solidify into large blocks that are cut into slices. Base plates of the known shape are punched out of the discs. The plates become very pliable when heated without noticeably sticking or shrinking.
