| Outline of Final Research Achievements |
The aim of this study was to observe the food transfer and crush from eating to swallowing during mastication. Dynamic observation was performed using an endoscope camera with the point mobile for inside view and using a wireless capsule subminiature camera (MAJ-2028, Endocapsule, Olympus) for the occlusal view. Masticatory movements were simulated by opening and closing movements of the articulator by setting the foods on the artificial teeth of the maxillary and mandibular complete dentures. Using this new system, the phases of cutting, biting, and crushing the foods could be dynamically observed during mastication.
In addition, dynamic observation of the masticatory phases was achieved in the patient (Male, 55 yo) using the endoscope camera with the point mobile on the left molar.
