| Outline of Final Research Achievements |
In order to elucidate the precise occlusion in an objective fashion, different from empiric-based concept, we have made up a system using micro 3-axis acceleration sensor which had been developed by Micro Electro Mechanical System technology. The sensors were fixed on the buccal surface of the tooth crown. The modality was far from traditional one which had been a thin film-shaped and been set on the occlusal table. When tapping, heavier force was produced at the incisors than at the posterior teeth, contrary to the common and conventional notion that heavy forces had been produced at the posterior tooth during mastication. And the direction of force was coincident with that of tooth axis at the molar region when tapping. At the incisor region, however, it was not parallel to that of the tooth axis as if it had brought about flare out of the teeth. This system enables precise evaluation of the force direction by tapping and will be reliable measurement apparatus with modifications.
