Abstract |

内容記述 |
We used ultrasonography to examine how insertion of a mandibular bilateral extension denture affected tongue movements during mastication. The study was done in two phases. Experiment I examined tongue movements during mastication of individuals with a well-established occlusal-supporting area. The subjects were 10 young individuals, 10 older dentate individuals and 10 individuals wearing complete dentures. Experiment II examined the effect of a mandibular bilateral extension denture on tongue movements during mastication. The subjects were 6 patients who were provided with mandibular bilateral extension dentures. Tongue movements during left and right unilateral mastication were examined by ultrasonography. Coronal B-mode images at the lowest points of five consecutive M-mode waveforms in each stage were traced. Height differences between the left and right sides of the tongue were compared between each stage. In both left and right unilateral mastication, the height differences significantly decreased progressively between each stage in subjects with a well-established occlusal-supporting area. In all patients, no significant difference was observed between each stage before treatment. However, the height differences significantly decreased for each stage following treatment, and placement of the denture affected tongue movement in the final mastication stage. Placement of a mandibular bilateral extension denture affected tongue movement during mastication and the height differences of the two sides of the tongue gradually decreased as mastication progressed. |
