Uncertainty analysis of a non-contact image-based measurement system for tracking mandibular movements path

Abstract

Tracking mandibular movements is essential for the production of personalized gnathologic and prosthetic devices. The market offers several solutions of optical systems aimed at tracking the jaw, instruments that, using a camera and specific markers, allow reconstructing free mandibular movements. The purpose of this study is to analyse the measurement uncertainty of one of these new systems through comparison with a reference technique on simple linear displacements.
