Abstract
In accordance with the present invention, there can be provided a partial dental prosthesis comprising artificial teeth and a denture base holding the artificial teeth, wherein at least one end of the partial dental prosthesis is adjacent to a retentive tooth, which is improved in that a projecting member made of an elastic material is provided at one or two ends of the partial dental prosthesis so as to be closely or elastically in contact with an undercut of the natural tooth. The partial dental prosthesis does not cause natural teeth adjacent to the partial dental prosthesis to be damaged and can be stably and steadily supported on an alveolus ridge of a patient.
