している等の場合を含むものである。Function According to the present invention, since the piezoelectric material is attached to the inner surface of the denture base, compressive stress or the like acts on the piezoelectric material when the denture is used, and an electromotive force is generated from the piezoelectric material. This piezoelectric material is partially exposed from the inner surface of the denture base. Therefore, this piezoelectric material is in close contact with the mucous membrane of the alveolus. Therefore, the electromotive force from the piezoelectric material acts on the mucous membrane and the alveolar bone covered by the mucous membrane. This will strengthen the alveolar bone and prevent the alveolar bone from becoming thin and declining. Therefore, in this specification, the exposure refers to exposure in the sense that the electromotive force from the piezoelectric material directly acts on the mucous membrane, and includes, for example, cases where the membrane is coated with a conductive material.
