Abstract
On the basis of a hollow die including over-shell and a cap drawn onto a proximal connector of the die, an ear impression is produced directly in the auditory canal that is filled with ear impression material. Displaced ear impression material thereby flows through a channel in the cap into the hollow interior of the die. A negative is produced from the ear impression together with a screwed-on fixing star, this negative containing impressions of the points of the fixing star. After injection of otoplastic material and repositioning of a fixing star with a die, over-shell and cap into the fixing depressions, a finished otoplastic shell can then be produced from the negative.
