Sets of posterior teeth
First Claim
1. Sets of posterior teeth which may be used for the production of dentures;
- said sets comprising;
a first set of posterior teeth which provide for lingualized occlusion, the first set including maxillary premolars and molars and mandibular premolars and molars, all the teeth having lingual and buccal cusps, there being a central mesial-distal fossa between the cusps of the mandibular premolars and molars, the maxillary premolars and molars having prominent lingual cusps with relatively steep cusp angles, preferably in the range of 30°
or more, and the mandibular premolars and molars having shallow lingual and buccal cusp angles in the range of 15-2020 ; and
a second set of posterior teeth which provide zero degree monoplane occlusion surfaces, the second set including maxillary and mandibular premolars and molars, all of the teeth of the second set having flat lingual and buccal cusps, and a central mesial-distal fossa, the central mesial-distal fossa of the mandibular teeth being designed to accommodate the lingual cusps of the maxillary teeth of the first set.

Abstract
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.

9. A set of posterior teeth which may be used for the production of dentures;
- said set comprising;
full length premolars which are of sufficient length to harmonize with canines, the premolars being provided with flat buccal and lingual cusps to achieve zero degree monoplane occlusion surfaces, and the facial surfaces of the maxillary premolars having a cusp like effect by having marginal ridges slightly lower than the center of the buccal and lingual cusps; and
molars which progressively decrease in length.
