Description
Verfahren zur Behandlung elastischer Abdruckmassen für die Zahnheilkunde und die Drucktechnik I)ie für die ZahntechniX und die Drucktechnik serwelldeten elastischen Abdruckmassen haben den Nachteil, daß der soeben erstellte Abdruck verhältnismäßig schnell, insbesondere oberflächlich, seine Form verliert (verändert).Process for the treatment of elastic impression materials for dentistry and printing technology I) ie for the dental technology and the printing technology serwelldeten elastic Impression compounds have the disadvantage that the impression just made is relatively quickly, especially superficially, loses (changed) its shape.
Es sind besondere Vorsichtsmaßregeln notwendig, welche eine kurze Zeit lang eine Formenkonstanz garantieren sollen. Special precautions are necessary, some of which are brief To guarantee a constant shape for a long time.
In der Notwendigkeit dieser Vorsichtsmaßregeln liegt die größte Schwäche Ider bisherigen elastischen Abdruckmassen. The need for these precautions is the greatest weakness I the previous elastic impression materials.
Erfindungsgemäß werden diese Schwierigkeiten dadurch behoben, daß der Abdruckmasse eine hygroskopisc'he Substanz zugesetzt wird. Solche hygroskopisch wirkenden Substanzen sind z.B. According to the invention, these difficulties are eliminated in that a hygroscopic substance is added to the impression material. Such hygroscopic acting substances are e.g.
Glycerin, Glykol, milchsaures Natrium, Phosphorsäure usw.Glycerin, Glycol, Sodium Lactic Acid, Phosphoric Acid, etc.
Diese Stoffe können dem Wasser zugesetzt werden, welches zum Anteigen der Abdrnckmasse dient, oder bereits der festen Abdruckmasse. These substances can be added to the water that is used to make dough the impression compound is used, or already the solid impression compound.
Beispiel 1 Eine elastische Abdrudkmasse, die z. B. aus Alginat und einem Calciumsalz oder aus einem aus Pektin gewonnenen Stoff, der mit Calciumsalzen härtbar ist und einem Calciumsalzzusatz besteht, wird mit Zusatz von Glycerin zu dem zum Anteigen notwendigen Wasser angerührt. Example 1 An elastic Abdrudkmasse z. B. from alginate and a calcium salt or a substance obtained from pectin that contains calcium salts is curable and contains an addition of calcium salts, becomes with the addition of glycerine mixed with the water necessary for the dough.
Beispiel 2 Einer elastischen Abdruckmasse wird als hygroskopische Substanz Glykol oder Phosphorsäure zugesetzt. Example 2 An elastic impression material is called a hygroscopic Substance glycol or phosphoric acid added.
Beisp-iel 3 Die trockene Form einer elastischen Abdruckmasse wird mit einem festen Salz versetzt, welches an sich hygroskopisch ist und dessen hygroskopische Eigenschaften nach dem Anrühren der Abdruckmasse zur Geltung gelangen. Example 3 The dry form of an elastic impression material is mixed with a solid salt, which is hygroscopic in itself and its hygroscopic Properties come into their own after the impression material has been mixed.
PATENTANSPRCCHE: 1. Verfahren zur Behandlung elastischer Abdruckmassen für die Zahnheilkunde und die Drucktechnik, dadurch gekennzeichnet, daß dem zum Anteigen notwendigen Wasser ein hygroskopisches Mittel, wie z. B. Glycerin, Glykol, milchsaures Natrium, Phosphorsäure usw. zugesetzt wird, um die Formkonstanz der Abdruckmasse zu bewahren. PATENT CLAIMS: 1. Method for the treatment of elastic impression materials for dentistry and printing technology, characterized in that the for Paste necessary water a hygroscopic agent, such as. B. glycerine, glycol, Sodium lactic acid, phosphoric acid, etc. is added to maintain the shape of the To preserve impression material.
