Abstract

In this study, occlusal contact image on articulating paper record in the intercuspal position was clarified about the relation with occlusal adjacent portion determined from black silicone record and difference of reproducibility by the recording methods. Four kinds of recording methods, 3 times tapping, 3 times tapping with a middle clenching, 5 times tapping and 5 times tapping with a middle clenching, were examined. The occusal contact image of the first molar was changedto a binary image and analyzed via the personal computer.<BR>The results were asfollows: 1. There was no significant difference between the area of occlusal contact image by each method. 2. In all methods, the coefficient of correlation between the area of occlusal contact image and occlusal adjacent portion increased according to the increase of the binary threshold of the occlusal adjacent portion. 3. For the correlation between the area of occlusal contact image and occlusal adjacent portion divided every 10μm (up to 40μm), the coefficients of 10-20μm and 20-30μm were successful. 4. There was no influence of the number of tapping times on dispersion of the area of occlusal contact image, but the dispersion decreased by clenching.<BR>Finally, an occlusal contact image could be influenced by dynamic change of occlusal contact, and the recording method that includes clenching has high reproducibility.
