摘要:
The present invention provides a dental hydraulic temporary sealing material composition on which a protection of tooth substance, such as tooth substance strengthening and control of secondary dental caries, can be expected by sustained-releasing various ions including a fluoride ion, while having a high initial setting ability. More specifically, the present invention provides a dental hydraulic temporary sealing material composition comprising 65.0% to 85.0% by mass of component (1): a hydraulic inorganic powder; 10.0% to 25.0% by mass of component (2): an organic solvent; 3.0% to 15.0% by mass of component (3): a resin; and 0.01% to 10.0% by mass of component (4): an ion sustained-release glass.

Disclosed herein is a two part retraction system that can be inserted into the sulcus to form a semi-rigid porous elastomer releasing a hemostatic agent suitable for sulcus retraction such that a dental impression may be completed by a dental practitioner.

Zur Herstellung paßgenauer oxidkeramischer Zahnersatzstücke in einem Arbeitsgang muß ein Schrumpfen des Gemisches aus Keramikteilchen mit Bindemitteln und/oder Anmischflüssigkeiten beim Sintern verhindert werden. Das erreicht man durch Zugabe von Teilchen aus leicht oxidierbaren Metallen, Metallsuboxiden und/oder Metallhydriden, die beim Sinter unter Sauerstoffaufnahme eine Volumenvergrößerung erfahren und die Sinterschrumpfung bei entsprechendem Mischungsverhältnis kompensieren.

Das Verfahren zur Trennung einer vorpolymerisierten Composite-Zahnfüllung von der Zahnhartsubstanz verwendet ein Isoliermittel, das aus einem Sol besteht, welches zweckmässig aus einer in Alkohol geguollenen und gelösten organischen oder anorganischen Gel bildenden Substanz gebildet ist. Die Isolierschicht wird vor dem definitiven Einzementieren des Inlays aus der Kavität herausgenommen. Das erfindungsgemässe Isoliermittel erlaubt die direkte Legung eines Inlays im Seitenzahnbereich ohne die Mitarbeit eines Zahntechnikers.
摘要:
The present invention relates to a kit of parts comprising Paste (A), Paste (B) and Paste (C), the pastes being characterized as follows: Paste (A) comprising at least one polyorganosiloxane with at least two olefinically unsaturated groups, and at least one organohydrogenpolysiloxane, at least one alkylsiloxane having at least one carbinol, silanol, alkoxy, carboxyl or amino group, optionally filler(s) and optionally additive(s); Paste (B) comprising at least one polyorganosiloxane optionally with olefinically unsaturated groups, at least one addition cure catalyst, optionally at least one alkylsiloxane having at least one carbinol, silanol, alkoxy, carboxyl or amino group, optionally filler(s) and optionally additive(s) Paste (C) comprising a softener, a condensation cure catalyst, optionally filler(s), and optionally additive(s) optionally at least one polyorganosiloxane optionally with olefinically unsaturated groups. The invention is also directed to a system for storing and delivering Paste (A), Paste (B) and Paste (C), the system comprising three compartments for storing the respective pastes, means for delivering the respective pastes to an outlet orifice and an interface for receiving a mixing tip. The kit of parts or the system is in particular useful for conducting a dental retraction and dental impression process.
摘要:
Im erfindungsgemässen Verfahren zur Sulkus-Retraktion wird mit einer aushärtbaren Verbindung (3) zuerst eine Gebiss-Abformung (8) hergestellt, welche nach dessen Aushärtung entnommen wird. In den Grenzbereich zwischen Zahn (1) und Zahnfleischrand (2) wird mit einem geeigneten Instrument ein Silikonmaterial (5) aufgetragen. Das kennzeichnende Merkmal dieses Silikonmaterials (5) ist dessen Volumenexpansion bei der Aushärtung. Die zuvor hergestellte Gebiss-Abformung (8) wird wieder auf die Zähne aufgesetzt, wodurch diese Abformung (8) eine einseitige Begrenzung für die Expansionsrichtung für das Silikonmaterial (5) bildet.
摘要:
Endodontic filling systems are provided having im proved properties over those known to the prior art. Endodontic points are provided comprising hydrophilic, polymeric compositions (40). Such points are swellable when placed into a prepared root canal space (36) and provide substantially complete filling of lateral cavity spaces (38) without invasion of the subapicial space. According to a preferred embodiment, such points are used in conjunction with pastes or fluids comprising hydrophilic, polymeric compositions.
