Abstract

The invention provides artificial teeth arranged in plates 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, being applicable to various arrangement of artificial teeth.

Claims

1. Artificial molar teeth arranged in plates attached in an oral cavity as a dental prosthetic appliance,

wherein 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.

3. The artificial molar teeth of claim 1, wherein the arrangement direction indication parts are formed of at least one of contour lines of contour parts, grooves formed between the adjacent contour parts, and lines formed by coloring.

4. The artificial molar teeth of claim 1, wherein the arrangement direction indication parts are provided so as to extend in the sideway motion direction of the motion side.

5. The artificial molar teeth of claim 1, wherein the arrangement direction indication parts are provided so as to extend in the mesiodistal direction.

6. The artificial molar teeth of claim 5, wherein the arrangement direction indication parts of the molar teeth adjacent in an occlusal plane view are positioned linearly.

7. The artificial molar teeth of claim 1, wherein the arrangement direction indication parts are provided so as to extend in the buccal-lingual direction.

2. Artificial molar teeth including two or more molar teeth adjacently arranged in the mesiodistal direction in plates attached in an oral cavity as a dental prosthetic appliance,

wherein 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, and at least one set of the arrangement direction indication parts in the adjacent molar teeth is extended generally in the parallel direction.

9. The artificial molar teeth of claim 2, wherein the arrangement direction indication parts are formed of at least one of contour lines of contour parts, grooves formed between the adjacent contour parts, and lines formed by coloring.

10. The artificial molar teeth of claim 2, wherein the arrangement direction indication parts are provided so as to extend in the sideway motion direction of the motion side.

11. The artificial molar teeth of claim 2, wherein the arrangement direction indication parts are provided so as to extend in the mesiodistal direction.

12. The artificial molar teeth of claim 2, wherein the arrangement direction indication parts are provided so as to extend in the buccal-lingual direction.

8. An arrangement confirmation sheet for confirming the arrangement state of artificial molar teeth having linear arrangement direction indication parts provided on occlusal planes in at least one position or more showing the arrangement direction in plates,

wherein confirm lines overlapping with the arrangement direction indication parts in the normal arrangement state are provided in a base sheet through which the back side can be seen.
