PLAQUE DE PROTHÈSE DENTAIRE ET SON PROCÉDÉ DE FABRICATION, DENT ARTIFICIELLE ET SON PROCÉDÉ DE FABRICATION, ET PROTHÈSE DENTAIRE À PLAQUE ET SON PROCÉDÉ DE FABRICATION
This invention provides a denture base with which it is not necessary for a collar portion of an artificial tooth to be cut beforehand in order to ensure a sufficient thickness in regard to a base portion of a denture for a patient with a high alveolar ridge. The denture base comprises: a base portion； a socket that is demarcated by a step portion from a gingival area of the base portion and to which an artificial tooth is to be attached； and interdental papilla areas of the gingival area, which are positioned at both ends of the socket along a tooth row and which correspond to interdental papillae between adjacent teeth, wherein, in a state in which the socket is facing upward, a basal surface of the socket has a ridge-shaped socket apex portion interconnecting the interdental papilla areas at both ends and is configured by a surface that is convex overall, a peripheral area of the basal surface is in mutually continuous abutment with the step portion, and the socket apex portion is positioned at substantially the same height as, or higher than, apex portions of the interdental papilla areas that are seen from a labial side in a state in which the artificial tooth is attached to the socket.
