It the frequency of occurrence of acoustic signals in conducted investigations was estimated was emitted by ponds temporo-mandibular in individual defects of occlusion.

The studies were carried out among the group of 72 children aged 12- 14 years, including 40 girls and 32 boys. The children qualified for the acoustic examination were divided into 8 groups, regarding the disorder of the stomatognathic system. The appliance made in The Department of Acoustic of Engineering College of Gdańsk was used for transforming, recording and the subsequent analysis.

In each of the patients examined, 4 measurements were made, two in every temporomandibular joint. The first measurement included resting joint signal recording, the second one full mandible movement cycle recording.

The presence of the clicks registered was found in 60 cases from the examined group, which makes 83.3% of the whole patient group. The clicks were found in every mandible low frequency movement phase in each patient form this group mentioned above. They were strongly marked in four malocclusions: progenia, posterior occlusion, anterior occlusion and closed bite. Moreover, in case of measurements range for high frequency limen , the same malocclusions dominated, however the signals were not registered in all of the phases and they were not so numerous. The results may indicate, that in some occlusal disturbances the temporomandibular joints disorders are more frequent and quicker. The of acoustic wave enabling the creation the normogramu of acoustic wave for individual defects of occlusion characteristic features were not got.
