ARTIFICIAL POSTERIOR TOOTH FOR HUMANS

摘要

The present invention concerns artificial posterior teeth, namely large and small posterior teeth for the upper and lower human jaws. The occlusal surface of the tooth has at least one vestibular cusp (6) and at least one palatal cusp (5) between which a longitudinal groove (7) runs in the longitudinal direction of the tooth. The vestibular cusps (6) of the posterior teeth of the lower jaw engage in the grooves in the posterior teeth of the upper jaw, and the palatal cusps (5) of the posterior teeth of the upper jaw engage in the longitudinal grooves of the posterior teeth of the lower jaw. The longitudinal grooves (7) and the palatal/lingual cusps (5) and vestibular cusps (6), respectively, of the posterior teeth (34 to 37 and 24 to 27) are adapted to one another such that, in the region of the longitudinal grooves (7), at least one rest zone (11) is formed in which there is point-wise contact in the closed position of the posterior teeth (34 to 37 and 24 to 27, respectively).
