Abstract

In this paper we investigate the relation between lateral cross-bite disorders and the sounds generated by the temporo-mandibular joint (TMJ). TMJ vibrations are recorded clinically by palpation and auscultation and also electronically by accelerometers. TMJ signals are filtered, amplified, digitized and stored on a computer. Based on joint time-frequency moments calculated from evolutionary spectrum, sounds are categorized into four classes. Palpation, auscultation and time-frequency classification findings are presented.
