Abstract

A method of fabricating a plate denture, comprises: creating a denture plate having a concave socket formed thereon and a vertical groove formed on a bottom surface of the socket; applying an adhesive material to the socket and the vertical groove; embedding a reinforcing structure in the vertical groove to which the adhesive material is applied; and arranging an artificial tooth in the socket to which the adhesive material is applied.

Claims (71)

1. A method of fabricating a plate denture, comprising:

creating a denture plate having a concave socket formed thereon and a vertical groove formed in a bottom surface of the socket;

applying an adhesive material to the socket and the vertical groove;

embedding a reinforcing structure in the vertical groove to which the adhesive material is applied; and

arranging at least one artificial tooth in the socket to which the adhesive material is applied such that the reinforcing structure and the at least one artificial tooth are spaced apart from each other by the adhesive material and are bonded via the adhesive material.

2. The method of fabricating a plate denture of claim 1 , wherein

the at least one artificial tooth includes at least six front teeth comprising left and right central incisors, lateral incisors, and canines, wherein

the vertical groove and the reinforcing structure are formed in an arcuate shape along dentition, wherein

the vertical groove and the reinforcing structure have a mesiodistal width of half or more of a mesiodistal width of molars, and wherein

the vertical groove and the reinforcing structure have a lip-lingual or buccolingual width of 1.5 mm to 15.0 mm.

3. The method of fabricating a plate denture of claim 2 , wherein

the plate denture is a partial plate denture, and wherein

the reinforcing structure comprises a minor connector connected to a retainer for retaining the plate denture in a mouth of a user.

4. The method of fabricating a plate denture of claim 3 , wherein

the embedding of the reinforcing structure comprises arranging at least part of the reinforcing structure at a position 0.001 mm to 1.0 mm apart from an inner wall defining the vertical groove.

5. The method of fabricating a plate denture of claim 3 , wherein

the creating of the denture plate comprises:

acquiring design data of the denture plate having the socket and the vertical groove formed thereon; and

creating the denture plate, based on the design data.

6. The method of fabricating a plate denture of claim 2 , wherein

The embedding of the reinforcing structure comprises arranging at least part of the reinforcing structure at a position 0.001 mm to 1.0 mm apart from an inner wall defining the vertical groove.

7. The method of fabricating a plate denture of claim 2 , wherein

the creating of the denture plate comprises:

acquiring design data of the denture plate having the socket and the vertical groove formed thereon; and

creating the denture plate, based on the design data.

8. The method of fabricating a plate denture of claim 1 , wherein

the plate denture is a partial plate denture, and wherein

the reinforcing structure comprises a minor connector connected to a retainer for retaining the plate denture in a mouth of a user.

9. The method of fabricating a plate denture of claim 8 , wherein

the embedding of the reinforcing structure comprises arranging at least part of the reinforcing structure at a position 0.001 mm to 1.0 mm apart from an inner wall defining the vertical groove.

10. The method of fabricating a plate denture of claim 8 , wherein

the creating of the denture plate comprises:

acquiring design data of the denture plate having the socket and the vertical groove formed thereon; and

creating the denture plate, based on the design data.

11. The method of fabricating a plate denture of claim 1 , wherein

the embedding of the reinforcing structure comprises arranging at least part of the reinforcing structure at a position 0.001 mm to 1.0 mm apart from an inner wall defining the vertical groove.

12. The method of fabricating a plate denture of claim 1 , wherein

the creating of the denture plate comprises:

acquiring design data of the denture plate having the socket and the vertical groove formed thereon; and

creating the denture plate, based on the design data.

13. A plate denture comprising:

a denture plate having a concave socket formed thereon and a vertical groove formed in a bottom surface of the socket;

an adhesive material applied to the socket and the vertical groove;

a reinforcing structure arranged in the vertical groove and embedded in the adhesive material; and

at least one artificial tooth arranged in the socket and adhered by the adhesive material such that the reinforcing structure and the at least one artificial tooth are spaced apart from each other by the adhesive material and are bonded via the adhesive material.

14. The plate denture of claim 13 , wherein

the at least one artificial tooth includes at least six front teeth comprising left and right central incisors, lateral incisors, and canines, wherein

the vertical groove and the reinforcing structure are formed in an arcuate shape along dentition, wherein

the vertical groove and the reinforcing structure have a mesiodistal width of half or more of a mesiodistal width of molars, and wherein

the vertical groove and the reinforcing structure have a lip-lingual or buccolingual width of 1.5 mm to 15.0 mm.

15. The plate denture of claim 14 , wherein

the plate denture is a partial plate denture, and wherein

the reinforcing structure comprises a minor connector connected to a retainer for retaining the plate denture in a mouth of a user.

16. The plate denture of claim 14 , wherein

at least part of the reinforcing structure is 0.001 mm to 1.0 mm apart from an inner wall defining the vertical groove, and wherein

the adhesive material is applied to a space between at least part of the reinforcing structure and the inner wall defining the vertical groove.

17. The plate denture of claim 16 , wherein

the vertical groove has on its inner wall a protrusion, the protrusion being in contact with the reinforcing structure.

18. The plate denture of claim 13 , wherein

the plate denture is a partial plate denture, and wherein

the reinforcing structure comprises a minor connector connected to a retainer for retaining the plate denture in a mouth of a user.

19. The plate denture of claim 18 , wherein

at least part of the reinforcing structure is 0.001 mm to 1.0 mm apart from an inner wall defining the vertical groove, and wherein

the adhesive material is applied to a space between at least part of the reinforcing structure and the inner wall defining the vertical groove.

20. The plate denture of claim 19 , wherein

the vertical groove has on its inner wall a protrusion, the protrusion being in contact with the reinforcing structure.

21. The plate denture of claim 13 , wherein

at least part of the reinforcing structure is 0.001 mm to 1.0 mm apart from an inner wall defining the vertical groove, and wherein

the adhesive material is applied to a space between at least part of the reinforcing structure and the inner wall defining the vertical groove.

22. The plate denture of claim 21 , wherein

the vertical groove has on its inner wall a protrusion, the protrusion being in contact with the reinforcing structure.
