Abstract
A dental prosthesis is provided, manufactured from a one-piece or multi-piece prosthesis blank which is composed of a gum-colored material (14) and a tooth-colored material (14), especially each one being based on plastic material. The tooth-colored material (14) of the blank (10) has a diameter or a width of more than 5 cm and especially a substantially flat cylindrical shape with a diameter/height ratio of more than 2:1, preferably more than 3:1. The gum-colored and tooth-colored materials (14, 12) are bonded together by bonding, polymerization and/or integral production. The boundary (16) between the materials, as viewed in the direction of the dental arch course, is wave-shaped with alternating grooves and ribs (22, 24), and in the region of the anterior arch in the vestibular direction—is of radiant shape.
