Title: DENTURE PLATE AND METHOD OF MANUFACTURE THEREOF, ARTIFICIAL TOOTH AND METHOD OF MANUFACTURE THEREOF, AND PLATE DENTURE AND METHOD OF MANUFACTURE THEREOF
Abstract:
Provided is a denture plate with which it is not necessary for a collar portion of an artificial tooth to be cut in advance in order to ensure sufficient thickness for a plate portion of a plate denture in relation to a patient having a high alveolar ridge. This denture plate includes: a plate portion; a socket which is demarcated by means of a step portion with respect to a gingival part of the plate portion and into which an artificial tooth is fitted; and an interdental papilla part of the gingival part, located at both ends of the socket along the tooth row, and corresponding to an interdental papilla between adjacent teeth. In a state in which the socket is facing upward, a basal surface of the socket includes a socket top portion assuming a ridge shape linking the interdental papilla parts at both ends, and constitutes a convex surface as a whole. A border part of the basal surface abuts continuously against the step portion, and the socket top portion is positioned at substantially the same height as or higher than a top portion of the interdental papilla part visible from the lips side with an artificial tooth fitted into the socket.
