| Outline of Final Research Achievements |
The purpose of this study was to validate the concept “Quality of Mastication (QoL)” I have proposed before. We surveyed materials and methods to measure “QoM” exhaustively, examined the influence of “QoM” on brain and gnathological functions, and then tried to establish the assessments of QoM on prosthetic dentistry.
The following results were obtained: development of a new questionnaire with 18 question items, chronological changes of food bolus properties through mastication process and just before swallowing, a proposal of behavior modification to reduce one mouthful volume, the difference of tactile ability between teeth and implants, and influence of various stimulations on cerebral blood flows of prefrontal area. It proves that concept of masticatory efficiency alone is not enough to evaluate mastication, but the evaluation on the part of QoM is required before and after prosthodontic treatments.
