Description
Isoliermittel für zahntechnis che Zwecke In der allgemeinen Zahntechnik werden in großem Umfang Isoliermittel verwendet, die ein leichtes Ahlösen der für Abdruckzwecke benützten Massen von den Modellen ermöglichen.Isolating agents for dental technology purposes In general dental technology Insulating agents are used on a large scale to allow easy loosening of the for Allow masses of the models used for printing purposes.
Sämtliche bisher bekannten Isoliermittel besitzen jedoch die Nachteile, daß ihre Verwendbarkeit jeweils auf bestimmte, meist engbegrenzte Werkstoffkombinationen beschränkt ist. Dies hat zur Folge, daß bei den verschiedenen Arbeitsgängen für ein und dasselbe Objekt, infolge der vielen Werkstoffkombinationen, auch vielerlei Isoliermittel bereitgehalten werden mussen. However, all previously known isolating agents have the disadvantages that their usability in each case on certain, mostly narrowly limited combinations of materials is limited. This has the consequence that in the various operations for one and the same object, due to the many material combinations, also many different things Isolation must be kept ready.
So werden in der Zahntechnik zur Isolierung von Gips gegen Gips Natriumsilikatlösungen verwendet. In dental technology, for example, sodium silicate solutions are used to isolate plaster of paris from plaster of paris used.
Diese zeigen jedoch bei den Kombinationen Gips/ Kunststoff oder Gips/Wachs oder Kunststoff/Kunststoff keinen Isoliererfolg. Zur Isolierung von Gips gegen Wachs werden Präparate herangezogen, bei denen fette oder ätherische Öle die wirksame Komponente darstellen. Diese haben wiederum bei der Isolierung von Gips gegen Gips oder Kunststoff gegen Gips keine Wirksamkeit. Auch die zur Isolierung von Wachs gegen Kunststoff dienenden Ole, wie z. B. auch Silikonöle, sind bei anderen Werkstoffkombinationen als Isoliermittel nicht verwendbar. So versagt Silikonöl, das bei Kunststoff gegen Wachs eine besonders gute Isolierwirkung aufweist, wenn es um das Isolierproblem Gips/Gips oder Gips/Kunststoff, vor allem im Warmverfahren, geht. Die weiter in der Zahntechnik zur Isolierung von Kunststoffzähnen gegen Gips verwendeten folienbi ldenden Kunststoffe oder Calciumchloridlösungen sind z. B. bei Kunststoff/Wachs oder Porzellan/Wachs oder Metall/Metall völlig ungeeignet. Auch die zur Isolierung von Metall gegen Metall verwendeten Aufschwemmungen anorganischier Substanzen in Spiritus sind bei anderen Werkstoffkombinationen nicht verwendbar.However, these show with the combinations plaster of paris / plastic or plaster of paris / wax or plastic / plastic no insulation success. For isolating plaster of paris from wax Preparations are used in which fatty or essential oils are the most effective Represent component. These, in turn, have to do with the isolation of plaster of paris against plaster of paris or plastic against plaster of paris is not effective. Also those used to isolate wax against plastic oils, such as. B. also silicone oils, are with other material combinations Cannot be used as an isolating agent. For example, silicone oil fails, as opposed to plastic Wax has a particularly good insulating effect when it comes to the insulation problem Plaster of paris / plaster of paris or plaster of paris / plastic, especially in the hot process, works. The further in In dental technology, folienbi used to isolate plastic teeth from plaster of paris Ldenden plastics or calcium chloride solutions are z. B. with plastic / wax or porcelain / wax or metal / metal completely unsuitable. Even those for insulation of metal against metal used suspensions of inorganic substances in Spirit cannot be used with other material combinations.
Zu dieser Beschränkung der Verwendbarkeit der bisher bekannten zahntechnischen Isoliermittel kommt als weiterer Nachteil hinzu, daß diese Mittel vielfach selbst bei den Werkstoffkombinationen, für welche sie an sich geeignet sind, nicht absolut sicher arbeiten. To this limitation of the usability of the previously known dental technology Another disadvantage is that insulating agents are often used by themselves not absolutely in the case of the material combinations for which they are suitable per se work safely.
So neigen z. B. Öle dazu, Formungenauigkeiten zu ergeben, die äußerst unerwünscht sind.So tend z. B. oils to give form inaccuracies that extremely are undesirable.
Weiterhin war bei einem Teil dler bisherigen Isoliermittel, zur Erzielung einer einwandfreien Isolierung, eine mehrfache Behandlung der zu isolierenden Stellen notwendig, wodurch eine Schichtdicke erzeugt wurde, die ebenfalls wiederum zu Formungenauigkeiten führte. War die Formgenauigkeit aber das primär erstrebenswerte, so ließ sich in diesen Fällen eine unvollständige Isolierung nicht vermeiden, die dann wiederum umfangreiche Nacharbeiten notwendig machte. Furthermore, some of the previous isolating agents were used to achieve this perfect insulation, multiple treatment of the areas to be isolated necessary, whereby a layer thickness was created, which in turn also leads to inaccuracies in the shape led. However, if the accuracy of the shape was the primary thing to strive for, then in In these cases, incomplete isolation cannot be avoided, which in turn made extensive rework necessary.
Gegenstand der vorliegenden Erfindung sind Isoliermittel für zahntechnische Zwecke, welche die erwähnten Nachteile nicht besitzen und eine einwandfreie Isolierung der verschiedenartigsten Werkstoffkombinationen ermöglichen. The present invention relates to insulating agents for dental technology Purposes that do not have the disadvantages mentioned and perfect insulation of the most varied of material combinations.
Diese neuen Isoliermittel bestehen erfindungsgemäß aus Silikonen oder Zubereitungen dieser, wie Silikonemulsionen, gegebenenfalls mit Zusätzen von Kunststoffen, wie Polyvinylverbindungen, und/oder Metallhalogeniden. According to the invention, these new isolating agents consist of silicones or preparations of these, such as silicone emulsions, optionally with additions of Plastics such as polyvinyl compounds and / or metal halides.
Die neuen Isoliermittel gemäß der vorliegenden Erfindung besitzen ausgezeichnete Isolierwirkungen bei allen in der Zahntechnik in Frage kommenden Werkstoffkombinationen. Es ist daher möglich, bei der Modellierarbeit mit einem einzigen Isoliermittel auszukommen, wodurch eine erhebliche Vereinfachung der Arbeitsweise erreicht und ein beträchtlicher Zeitgewinn erzielt wird. Darüber hinaus weisen die Isoliermittel gemäß der vorliegenden Erfindung den Vorteil auf, daß sie z. B. im Gegensatz zu den bisher üblichen wasserglashaltigen Zubereitungen nicht verkrusten, wodurch ein wesentlich genaueres und saubereres Arbeiten als bisher ermöglicht wird. Possess the new insulation means according to the present invention excellent insulating properties for all those in question in dental technology Material combinations. It is therefore possible to use a get along with a single isolating agent, which considerably simplifies the operation achieved and a considerable gain in time is achieved. In addition, the Insulating means according to the present invention have the advantage that they are e.g. B. in In contrast to the preparations containing water glass that have been customary up to now, do not encrust, which enables a much more precise and cleaner work than before.
Die neuen Isoliermittel können in an sich bekannter Weise, z. B. durch Aufpinseln auf die zu isolierenden Flächen aufgebracht werden. Auf Grund ihrer besonderen Eigenschaften können sie jedoch besonders vorteilhaft mit Hilfe einer an sich bekannten Spritzpistole, beispielsweise unter Verwendung von Druckluft oder Kohlendioxyd aus einer Stahlflasche, auf die gewünschten Oberflächen aufgesprüht werden. The new insulating means can be used in a manner known per se, for. B. can be applied by brushing onto the surfaces to be isolated. Because of your However, they can be particularly advantageous with the help of a special properties known spray gun, for example using compressed air or Carbon dioxide from a steel bottle, sprayed on the desired surfaces will.
Hierdurch wird nicht nur ein besonders rasches Arbeiten gewährleistet, sondern auch eine in alle Teile des Modells eindringende intensive Isolierung ermöglicht.This not only ensures particularly fast work, but also enables intensive insulation to penetrate all parts of the model.
