Abstract
A denture includes an upper and lower row of teeth, with a continuous chewing bar embedded along the buccal cusps of at least part of the lower row. Insert members are embedded in the opposed occlusal faces of teeth in the upper row, and are shaped to form arches or indents against which the chewing bar travels on articulation of the denture to create a scissors action.
