3D virtual automated modeling of custom posterior concha module

摘要

A virtual 3D modeling of a custom posterior concha module from a digital ear impression. This modeling is done with 3D inserts that fill the posterior concha area and are merged into a concha ring, concha plate, or another custom solid or hollow 3D object. The 3D object is integrated with the custom concha and custom canal modules. The resulting 3D mold is the virtual custom hearing aid shell or earmold. This method is suitable for modeling Full-Shell custom hearing aids, and Full-Shell, Shell, Skeleton, and Semi-skeleton earmolds. It is also applicable to modeling a Canal-lock and Helix-lock.
