METHOD AND APPARATUS FOR PRODUCING AN EAR IMPRESSION AND FOR FURTHER PROCESSING OF THE EAR IMPRESSION INTO AN OTOPLASTIC SHELL

摘要

ABSTRACT OF THE INVENTIONOn the basis of a hollow die including over-shell and acap drawn onto a proximal connector of the die, an ear impressionis produced directly in the auditory canal that is filled withear impression material. Displaced ear impression materialthereby flows through a channel in the cap into the hollowinterior of the die. A negative is produced from the earimpression together with a screwed-on fixing star, this negativecontaining impressions of the points of the fixing star. Afterinjection of otoplastic material and repositioning of a fixingstar with a die, over-shell and cap into the fixing depressions,a finished otoplastic shell can then be produced from thenegative.
