| Research Abstract |
The purpose of this study is to find the relevance of the factors that cuspal interference causes by simultaneous measurement of jaw movement and the masseter active mass from the viewpoint of exercise physiology.
We aimed to quantify the measurement of the periodontal sensation and the occlusion contact by observing a change in the periodontal sensation with jaw movement, an occlusal contact appearance, and masseter activity.
As a result of having measured the periodontal sensation threshold in the normal state using an electronic algesimetry device(electronic von Frey anesthesiometer), the possibility to use this information as criteria for detecting abnormal periodontal sensation was suggested.
Also, using silicone impression material, we can evaluate an occlusal contact in detail.
