Contactless measurement strategies and apparatus for mandibular movements monitoring in gnatology

This paper deals with the development of an innovative approach that allows performing non invasive measurements of jaw movements with application to the field of gnatography. An experimental apparatus has been also realized that includes both hardware and software sections. The main characterizing feature of the measurement system proposed here consist in the complete absence of any invasive device with respect to the patient, in fact a stereoscopic artificial vision approach has been exploited to our aims. A large set of experimental verifications of the proposed strategy has been performed and the results obtained confirm the suitability of the approach.
