Method of arranging artificial molar teeth

摘要

Artificial teeth are arranged in plates capable of being attached in an oral cavity as a dental prosthetic appliance, in which one or more linear arrangement direction indication parts showing the arrangement direction in the plates are provided on an occlusal plane of each of the molar teeth. At least one set of arrangement direction indication parts of the adjacent molar teeth is configured so as to extend generally in parallel direction. At least one set of arrangement direction indication parts of the antagonist upper molar teeth and lower molar teeth is configured so as to extend generally in parallel direction. The artificial molar teeth are arranged at an appropriate position according to the oral cavity environment of each patient, without requiring advanced skills and experiences, and are applicable to various arrangements of artificial teeth.

1. A method of arranging a plurality of artificial molar teeth in a plate to be attached in an oral cavity as a dental prosthetic appliance, the method comprising:
positioning the artificial molar teeth in the plate, each artificial molar tooth of the artificial molar teeth comprising an arrangement direction indicator formed by a straight line crossing on an occlusal surface of the artificial molar tooth, the arrangement direction indicator showing an arrangement direction in the plate, said arrangement direction indicator passing through contour portions and grooves of the occlusal surface and extending linearly in an occlusal plane view, and said arrangement direction indicator comprising a line formed by coloring, wherein said line extends in a direction generally perpendicular or generally parallel to a mesiodistal direction when said artificial molar tooth is arranged in the plate; placing an arrangement confirmation sheet over the occlusal surfaces of the artificial molar teeth positioned in the plate, the arrangement confirmation sheet comprising an elongated transparent and elastic sheet formed with line markings thereon; and adjusting the position of each artificial molar tooth of the artificial teeth on the plate so as to match said arrangement direction indicator on each artificial tooth with said line markings on the arrangement confirmation sheet.
