抄録

In this investigation, functional displacement of upper and lower molars were revealed using the displacement transducer type M-3. This transducer was invented by Miura in order to reveal three dimensional tooth displacement.<BR>The results were as follows:<BR>1. In general, each upper molar moved in the apical palatal direction while each lower molar moved in the lingual direction.<BR>2. For each upper molar, the amount of displacement varied proportionally depending on the clenching force. The direction of displacement was towards the palatal side.<BR>3. For each lower molar, the amount of displacement varied proportionally depending on the clenching force. The direction of displacement was to the lingual side.<BR>4. The amount of displacement depending on the clenching force was larger in each upper molar than that in each lower molar.<BR>5. It was suggested that the relative position of the upper and lower molars and the relation of their occlusal contacts at the intercuspal position vary depending on the clenching force.
