Abstract (EN):
This paper presents the development of a
new prototype system for acquisition and analysis of
the 3D mandibular movement. In Dental Medicine,
the study of the mandibular movement is very
important in oral rehabilitation treatments, since it
allows the diagnosis of clinical pathologies in the
temporomandibular joints and therefore, it helps
medical doctors to select the most adequate treatment
plan and its future assessment. In this work, a facial
arc, commonly used in Dental Medicine, was adapted
to incorporate electromagnetic sensors to measure the
movement of the mandible. Thus, some parts of the
arc were redesigned, in order to ensure the best
comfort for patients, and a compatible support for the
sensors were designed. A complete new user interface
was also developed to display and analyse the
3D movement acquired. This software integrates a
neural network algorithm to accomplish the
conversion of the output voltage of the electromagnetic
sensors employed into 3D cartesian coordinates.
The prototype developed reveals to be easy to use,
comfortable for patients and capable of being
produce at an affordable price.
