Abstract
This disclosure relates to a denture having a porous metal gauze as a denture plate formed of plural wire nets with a straight wire used as warps and wefts. The nets are laid one over another in layers in the manner that the meshes thereof are staggered each other with respect to the direction of thickness and the crossing portions of the warps and wefts in the same plane and the crossing portions of the warps and wefts in contact with each other in the direction of thickness are sintered to have a plurality of minute and complicatedly curved pores in the porous metal gauze. The denture permits penetration of saliva and food liquid through the thickness of the denture plate to supply oxygen and nutrient to the mucous membrane under the plate to thereby maintain physiological function and health of the membrane and to provide a sense of wearing the denture and a sense of bite occlusion in such a natural state as would hardly be brought about by a conventional denture.
