[PROBLEMS] When polishing the denture, to encourage the stirring of the abrasive polishing material to flow uniformly and sufficiently to the entire surface of the denture, by suppressing the staying abrasive such as depressions of the occlusal surface of the dental prosthesis, and to make the entire surface including the occlusal surface of the denture can be uniformly and sufficiently polished. The apparatus includes a first rotating shaft 7 is rotated by the driving force of the motor 6a, the second rotary shaft 9 rotates while revolving around the first rotary shaft 7 with the rotation of the first rotary shaft 7, the comprising a rotation transmitting mechanism 8 for transmitting the rotation of the first rotary shaft 7 to the second rotary shaft 9, a denture holder 15 that rotates integrally with the second rotary shaft 9 provided on the second rotary shaft 9, the polishing bath while rotating the denture holder 15 in the 4 A denture polishing apparatus 1 for polishing a denture 28 which is held in the denture holder 15, the denture holder 15, a denture 28 held obliquely downward with respect to the horizontal plane 29 to have. BACKGROUND.【課題】 義歯を研磨する際、研磨材の攪拌を促して義歯の表面全体に研磨材が均一かつ十分に流れるようにし、義歯の咬合面の凹みなどに研磨材が滞留するのを抑えて、義歯の咬合面を含む表面全体を均一且つ十分に研磨できるようにする。【解決手段】 モータ6aの駆動力によって回転する第1回転軸7と、第1回転軸7の回転に伴って第1回転軸7の回りを公転しながら自転する第2回転軸9と、第1回転軸7の回転を第2回転軸9に伝達する回転伝達機構8と、第2回転軸9に設けられて第2回転軸9と一体に回転する義歯ホルダ15と、を備え、研磨槽4内で義歯ホルダ15を回転させながら義歯ホルダ15に保持された義歯28を研磨する義歯用研磨装置1であって、前記義歯ホルダ15は、水平面29に対して斜め下向きに義歯28を保持している。【選択図】 図1
