Sets of posterior teeth which may be used for the production of dentures; the sets including a first set of posterior teeth which provide for lingualized occlusion, and a second set of posterior teeth which provide zero degree monoplane occlusion surfaces. The second set includes maxillary and mandibular premolars and molars, all of the teeth having flat lingual and buccal cusps and a central mesial- distal fossa between the cusps, the central mesial-distal fossa of the mandibular teeth being designed to accommodate the lingual cusps of the maxillary teeth of the first set. The second set has been designed with full length premolars which are of sufficient length to harmonize with canines, the premolars being provided facial surfaces having a cusp like effect by having marginal ridges slightly lower than the center of the buccal and lingual cusps.
