More particularly the new shape facilitates the arrangement of the teeth in the mouth in a 'inore or less downwardly curved arch. In
addition, much fewer shapes of teeth need beheld in stock than heretofore. It will be seen further from the drawing that both the new upper and lower incisors can be applied not only in combination with one another but also with opposing teeth of other shapes.
What I claim as my invention is In artificial dentures, an'upper incisor having a substantially horizontal plane masticating surface and an opposed lower 1nc1sor having on its labial side a front surface proper, a biting edge adapted to engage the masticating surface of 'the upper incisor, and aninclined surface extending from said biting edge downward to the front surface proper and forming with the latter an obtuse angle. 1 p
