Description

Verfahren zur Herstellung von Zahnzementen. Es ist ein Verfahren bekannt, die Abspaltung von freier Phosphorsäure aus Zahnzementen dadurch zu verhindern, date der zum Anrühren der basischen Otv de verwendeten Phosphorsäure oder Lösung von phosphorsauren Salzen kolloidale Kieselsäure zugesetzt wird.Process for the production of dental cements. A method is known to prevent the splitting off of free phosphoric acid from dental cements date of the phosphoric acid or solution used to mix the basic Otv de of phosphoric acid salts, colloidal silica is added.

Die kolloidale Kieselsäure soll hierbei eine Bindung der Phosphorsäure durch Entstehung konlpleter Verbindungen bewirken.The colloidal silica is supposed to bind the phosphoric acid through the creation of complete connections.

Versuche haben ergehen. daß die Wirkung der kolloidalen Kieselsäure in der Hauptsache nicht durch, die Bildung einer Verbindung erreicht wird, sondern durch die auf die Atlweschhheit des Kolloids zurückzuführende Erhöhung der Viskosität. Diese Erhöhung der Viskosität bedingt eine Herabsetzung der Diffusionsmöglichkeit bzw. Diffusionsge-Schwill'digkeit.Attempts have been made. that the action of colloidal silica in the main not through, the formation of a connection is achieved, but due to the increase in viscosity due to the atlivity of the colloid. This increase in viscosity causes a reduction in the possibility of diffusion or diffusion swelliness.

B e i s p i e 1 : Einer zum Anrühren von Silikatzelitenten dienenden Lösung von Phosphorsäure und phosphorsauren Salzen wird z. B. Glyzerin zugesetzt. Während die ursprüngliche Lösung von Phosphorsäure und phosphorsauren Salzen durch eine dünne Dentinschicht innerhalb einer Stunde hindurchdiffundiert, war cl,ie Lösung mit weniger als i Prozent von Glyzerin auch noch nach zwei Tagen durch das Dentinplättchen nicht hindurchdiffumdliert.EXAMPLE 1: One used to mix silica elites Solution of phosphoric acid and phosphoric acid salts is z. B. glycerine added. While the original solution of phosphoric acid and phosphoric acid salts through a thin layer of dentine diffused through it within an hour was the solution with less than 1 percent of glycerine even after two days through the dentine platelet not diffused through.
