چکیده

In this paper we investigate the relation between lateral crossbite disorders and the sounds generated by the Temporomandibular 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.
