Abstract
A system and appertaining method are provided for electronically detailing an impression of an ear canal of a patient. A digitized geometric model of the impression is created, and a software tool is utilized to determine a bony part or canal direction, as well as first and second bends of the impression. An aperture of the impression is determined, and a cutting plane through the aperture is calculated such that the normal vector through the aperture plane aligns with a normal vector of the second bend plane. On establishing this congruence, modeling parameters optimized for modeling wireless based hearing instruments are evoked to optimized and automate design. This calculation can then be utilized for either manual or automated shaping and cutting operations.
