Artificial teeth

Abstract

The invention provides artificial teeth arranged in plates attached in an oral cavity as a dental prosthetic appliance, in which arrangement direction indication parts showing a directivity of arrangement in the plates extending in an apical-cervical direction or in a mesiodistal direction are provided at a vestibular side or an oral side. The arrangement direction indication parts extending in the apical-cervical direction are positioned linearly as seen from the vestibular side in a occluded state of mandibular teeth and maxillary teeth. The arrangement direction indication parts extending in the mesiodistal direction are positioned linearly as seen from the vestibular side in the state arranged in plates. The artificial teeth are arranged at an appropriate position according to an oral environment of each patient, without requiring advanced skills and experiences.

1 . Artificial teeth arranged in plates attached in an oral cavity as a dental prosthetic appliance,
 wherein arrangement direction indication parts showing a directivity of arrangement in the plates extending in an apical-cervical direction are provided at a vestibular side or an oral side.   
   
   
       2 . Artificial teeth arranged in plates attached in an oral cavity as a dental prosthetic appliance, having two or more teeth to be adjacently arranged in a mesiodistal direction,
 wherein arrangement direction indication parts showing a directivity of arrangement in the plates extending in an apical-cervical direction are provided at a vestibular side or an oral side of the teeth, and the arrangement direction indication parts of the teeth are extended generally in parallel in the state arranged in the plates.   
   
   
       3 . Artificial teeth having maxillary teeth and mandibular teeth arranged in plates attached in an upper jaw and a lower jaw in an oral cavity as a dental prosthetic appliance,
 wherein arrangement direction indication parts showing a directivity of arrangement in the plates extending in an apical-cervical direction are provided at a vestibular side or an oral side of the maxillary teeth and the mandibular teeth, and the arrangement direction indication parts of the maxillary teeth and the mandibular teeth are positioned generally in parallel in the state arranged in the plates.   
   
   
       4 . The artificial teeth of  claim 1 , wherein a cervical side end portion of the arrangement direction indication parts is positioned on a maximum contour ridge line generally in parallel to the mesiodistal direction in the state arranged in the plates. 
   
   
       5 . The artificial teeth of  claim 2 , wherein the cervical side end portion of the arrangement direction indication parts, and a contact point of adjacent teeth in the state arranged in the plates are positioned on a flat plane generally parallel to the mesiodistal direction. 
   
   
       6 . The artificial teeth of  claim 3 , wherein the arrangement direction indication parts of the maxillary teeth and the mandibular teeth are positioned linearly as seen from the vestibular side at a central occlusion position. 
   
   
       7 . The artificial teeth of  claim 1 , wherein the arrangement direction indication parts are lateral grooves extending from an apical side toward a cervical direction in the state arranged in the plates. 
   
   
       8 . The artificial teeth of  claim 1 , wherein the arrangement direction indication parts are ridge lines formed by facets formed at a mesial side and a distal side of a protruding cusp. 
   
   
       9 . The artificial teeth of  claim 1 , wherein the arrangement direction indication parts are lines formed to extend from the apical side toward the cervical direction in the state arranged in the plates, by coloring of the vestibular side and the oral side. 
   
   
       10 . Artificial teeth arranged in plates attached in an oral cavity as a dental prosthetic appliance,
 wherein arrangement direction indication parts showing a directivity of arrangement in the plates extending in a mesiodistal direction are provided at a vestibular side or an oral side.   
   
   
       11 . Artificial teeth arranged in plates attached in an oral cavity as a dental prosthetic appliance, having two or more teeth to be adjacently arranged in a mesiodistal direction,
 wherein arrangement direction indication parts showing a directivity of arrangement in the plates extending in the mesiodistal direction are provided at a vestibular side or an oral side of the teeth, and the arrangement direction indication parts of the teeth are positioned generally in parallel in the state arranged in the plates.   
   
   
       12 . Artificial teeth having maxillary teeth and the mandibular teeth arranged in plates attached in an upper jaw and a lower jaw in an oral cavity as a dental prosthetic appliance,
 wherein arrangement direction indication parts showing a directivity of arrangement in the plates extending in a mesiodistal direction are provided at a vestibular side or an oral side of the maxillary teeth and the mandibular teeth, and the arrangement direction indication parts of the maxillary teeth and the mandibular teeth are extended generally in parallel in the state arranged in the plates.   
   
   
       13 . The artificial teeth of  claim 10 , wherein the arrangement direction indication parts are positioned on a maximum contour ridge line generally parallel to the mesiodistal direction in the state arranged in the plates. 
   
   
       14 . The artificial teeth of  claim 11 , wherein the arrangement direction indication parts are positioned linearly as seen from the vestibular side in the state arranged in the plates. 
   
   
       15 . An arrangement confirmation sheet for confirming an arrangement state of artificial teeth having arrangement direction indication parts showing a directivity of arrangement in plates extending in an apical-cervical direction or a mesiodistal direction, provided on a vestibular side or an oral side,
 wherein confirm lines overlapping with the arrangement direction indication parts in a normal arrangement state are provided in a base sheet through which a back side can be seen.
