In the case of a denture made of pre-fabricated teeth, that exhibits molars and pre-molars for each jaw, upper and lower, at least on the upper molars at the lingual position, an incising ridge (24) is provided. The incising ridge is intended, in the occlusion position, to engage the masticatory surface (18) of the antagonist of the lower jaw (14) in each case. The masticatory surface (18) exhibits a sulcus (45) with at least some areas of convex arcuate projection (20, 22) by means of which the antagonist (14) may be centered in tripodized incuspidation on the incising ridge (24).
La présente invention s'applique à une prothèse faite de dents pré-fabriquées, qui comprend des molaires et des prémolaires pour chaque mâchoire, supérieure et inférieure et, au moins sur les molaires supérieures en position linguale, une crête d'incision (24). Cette crête vise, en position d'occlusion, à engager la surface masticatrice (18) de l'antagoniste de la mâchoire inférieure (14) dans chaque cas. La surface masticatrice (18) comporte un sillon (45) présentant au moins certaines zones de projection convexe arciforme (20, 22) qui permettent de centrer l'antagoniste (14) en intercuspidation à trois branches sur la crête d'incision (24).
