A collection of artificial front teeth comprises three morphological groups of teeth in the essential size classes. These groups are characterised by the proportions between the mesiodistal width of their vestibular surfaces in their cervical, central and incisive thirds in the longitudinal direction. The first group is a markedly cervical group, in which said widths are approximately equal, the second group is a markedly central group, in which the width of the central third is at least 1.15 larger than the width of the cervical third and the width of the incisive third is not larger than the width of the central third, and the third group is a markedly incisive group in which the width of the incisive third is at least 1.18 larger than the width of the cervical third and the width of the central third is smaller than the width of the incisive third.

Cette collection de dents frontales artificielles comprend trois groupes morphologiques de dents de différents ordres de grandeur qui se caractérisent par le rapport entre les largeurs mésio-distales de la surface vestibulaire de leurs tiers cervical, moyen et incisif dans le sens de la longueur. Le premier groupe est un groupe à prédominance cervicale, dans lequel lesdites largeurs sont à peu près égales, le deuxième groupe est un groupe à prédominance moyenne, dans lequel la largeur du tiers moyen est au moins 1,15 fois supérieure à la largeur du tiers cervical et la largeur du tiers incisif n'est pas supérieure à la largeur du tiers moyen, et le troisième groupe est un groupe à prédominance incisive dans lequel la largeur du tiers incisif est au moins 1,18 fois supérieure à la largeur du tiers cervical et la largeur du tiers moyen est inférieure à la largeur du tiers incisif.
