The purpose of this study was made to discriminate the premature contact tooth from the aspect of the occlusal sound.
Acouple of transducer (ceramic type microphone) was placed on the both side of temple region.
a) 1,000Hz vibration was directly applied to the each tooth of maxilla, and the propagation-time-difference of signals were measured.
b) Occlusal sounds from premature contact using the tooth crown on the maxillary dental arch were received and the same measurements were done.
The measured propagation-time-differences of a) and b) were nearly equal. From these results, it suggest that the premature contact tooth is detected from the occlusal sound.
