PROBLEM TO BE SOLVED: To provide a plate denture having high strength and excellent mountability in spite of using a resin plate.SOLUTION: The plate denture 1 is composed of: artificial teeth 2 and a denture plate part 3 for supporting the artificial teeth. The denture plate part 3 includes: a U-shaped plate edge 4 supporting the artificial teeth 2 and placed on the bank of a gum and a plate center 5 successively arranged inside the plate edge 4 by integrating the outer peripheral edge 7 of the center 5 with the U-shaped plate edge 4, so as to reinforce the plate edge 4. The plate center is constituted of a molded product of an acetal, and the plate edge 4 is constituted of a molded product of thermosetting resin or thermoplastic resin (e.g., acrylic resin) different from the acetal resin.COPYRIGHT: (C)2010,JPO&INPIT【課題】レジン床を使用しながらも、高い強度と優れた装着性を持つ有床義歯を提供する。【解決手段】人工歯2とそれを支える義歯床部3とからなる有床義歯1において、義歯床部3が、人工歯2を支持すると共に歯茎の土手に載るU字状の床縁部4と、このU字状の床縁部4に自身の外周縁7が一体化されることで床縁部4の内側に連設され、それにより床縁部4を補強する床中央部5とからなり、この床中央部がアセタルの成形品で構成され、床縁部4が前記アセタル樹脂とは異なる熱硬化性樹脂または熱可塑性樹脂(例えばアクリル樹脂)の成形品で構成されている。【選択図】図1
