Complex virtual models development for didactic purposes in the medical field

The many advantages in the availability of a virtual model of human parts regard, first of all, an easier shape comprehension of complex models in which different parts can be independently visualized and manipulated. The research job regards the virtual reconstruction of a maxillary arch physical model, through a reverse engineering approach. Thanks to the combination of laser scanning and mechanical touching, it was possible to obtain a CAD model in which all the teeth, the bone and the soft tissues can be independently viewed, moved and modified. The results can be applied for an improved communication between teachers and students, for a better comprehension of the inner correlation between different elements, and doctors and patients to the rapid overcoming of the initial cultural barrier. The research represents the first step of a fertile collaboration between engineering and medical staff, towards the implementation of innovative technological tools in human centred application, also in the field of virtual and augmented reality.
