| Research Abstract |
The sheet type sensor was inserted between each tooth in subjects with normal occlusion and the interdental pressure was measured with the jaws in a resting position and during occlusion. The results revealed pressure of 55.0-150.7 kPa with the jaws in resting position and 92.0-252.7 kPa during occusion. In both position, pressure tended to be greater than in the molar region than the anterior tooth region. Furthermore, the maxillary and mandibular interdental pressure differentials were 1.7.101.9 kPa and 8.7.157.9 kPa, respectively. The pressure differentials were greater during occlusion than in a resting position and in the molar region compared to the anterior tooth region both jaws. During occlusion, the interdental pressure defferential at the first occlusal contact point, which was greater than at other occlusal point.
