Abstract

Abstract Translated from German Mittels eines hohlen Stempels (1) mit Überschale (8) und einer auf einen proximalen Stutzen des Stempels gezogenen Kappe (10) wird direkt im Gehörgang, der mit Ohrabdruckmaterial gefüllt ist, ein Ohrabdruck gewonnen. Verdrängtes Ohrabdruckmaterial fließt dabei durch einen Kanal in der Kappe in den hohlen Innenraum des Stempels. Aus dem Ohrabdruck (15) zusammen mit einem angeschraubten Fixierkreuz (16) wird ein Negativ hergestellt, das Eindrücke der Spitzen (17) des Fixiersterns beinhaltet. Aus dem Negativ kann dann nach Eingießen von Otoplastik-Material und Repositionierung eines Fixierkreuzes mit Stempel, Überschale und Kappe, in den Fixiermulden eine fertige Otoplatik hergestellt werden. An ear impression is obtained directly in the auditory canal, which is filled with ear impression material, by means of a hollow stamp (1) with an outer shell (8) and a cap (10) pulled onto a proximal socket of the stamp. Displaced ear impression material flows through a channel in the cap into the hollow interior of the stamp. A negative is produced from the ear impression (15) together with a screwed-on fixing cross (16), which contains impressions of the tips (17) of the fixing star. After the otoplastic material has been poured in and a fixation cross with a stamp, over-shell and cap has been repositioned, a finished otoplatic can be produced from the negative in the fixing recesses.
