Description
Gegenstand der Erfindung ist ein Abdrucklöffel für zahnärtliche Zwecke, für den kennzeichnend ist die großoberflächige Ausgestaltung der mit den Abdruckmassen in Berührung kommenden Teile. The subject of the invention is an impression tray for dental purposes, it is characterized by the large-area design of the impression material parts coming into contact.
Beim praktischen Arbeiten mit den üblichen Abdrucklöffeln hat sich nämlich gezeigt, daß die breiigen bis zähflüssigen Abdruckmassen leicht aus dem Löffel abgleiten. Man hat bereits versucht, dieser Schwierigkeit dadurch zu begegnen, daß man die Abdrucklöffel gitterförmig ausbildete. When working in practice with the usual impression trays namely shown that the pulpy to viscous impression masses easily out of the Slide the spoon. Attempts have already been made to overcome this difficulty by that the impression spoons were designed in a grid-like manner.
Dies hat wieder den Nachteil, daß plastische Abdruckmassen, besonders wenn sie verhältnismäßig dünnflüssig sind, durch die Siebfläche hindurchtreten, was ebenfalls unerwünscht ist.This again has the disadvantage that plastic impression compounds, especially if they are relatively thin, pass through the sieve surface, which is also undesirable.
Bei den neuen Abdrucklöffeln sind erfindungsgemäß die mit den Abdruckmassen in Berührung kommenden Teile großoberflächig, d. h. die Innenflächen der Löffel sind chemisch oder mechanisch aufgerauht, so daß die pro Flächeneinheit in der Projektion zur Verfügung stehende Fläche dagegen relativ groß ist. Die Innenflächen können beispielsweise mit Hilfe eines Sandstrahls aufgerauht sein, sie können mit einem Waffelmuster versehen oder gekordelt sein. According to the invention, the new impression trays are those with the impression compounds parts that come into contact over a large surface, d. H. the inner surfaces of the spoons are chemically or mechanically roughened so that the per unit area in the projection The available area, however, is relatively large. The inner surfaces can be roughened for example with the help of a sandblast, you can with a Waffle pattern or be corded.
In der Zeichnung ist ein Abdrucklöffel nach der Erfindung in beispielsweiser Ausführungsform schaubildlich dargestellt. I ist der Handgriff des Löffels, 2 die Pfanne, die zum Al)druck dient, während 3 die aufgerauhte Innenfläche des Abdrucklöffels darstellt. In the drawing, an impression spoon according to the invention is shown by way of example Embodiment shown diagrammatically. I is the handle of the spoon, 2 the The pan used for printing Al), while 3 is the roughened inner surface of the impression tray represents.
