Abstract

The invention relates to a set of prefabricated teeth. The object of the invention is to make available a set of artificial teeth in which better adaptation of the artificial denture to the anatomical conditions of the patient, which are determined by the position of the condyles in the mandibular joint and their path of motion, is made possible. This object is attained by providing that the contact points between antagonist pairs of teeth are disposed on a sagittal and transversal compensation curve that is defined by the motion of the condyles of the mandible.

Claims

1. A denture set of prefabricated teeth, having at least one first tooth, selected from a group of teeth provided for a first jaw, and at least one second tooth, selected from a group of antagonists provided for a second jaw, wherein the at least one first tooth has at least one first contact point (4-7) on surfaces disposed facing the antagonists, wherein said at least one second tooth comes into contact with said at least one first contact point, wherein at least three contact points (5) are provided in a fossa of a respective molar or premolar, wherein a chewing cusp of the at least one second tooth comes into contact with said at least three contact points (5) in a intercuspidation position, wherein said at least one contact point (4-7) is disposed on a sagittal compensation curve (2) and a transversal curve (3), wherein said sagittal compensation curve (2) and said transversal curve (3) are determined by a motion of at least one condyle of a mandible (25).

2. The denture set of claim 1, wherein at least five contact points are provided on each said molar or premolar.

3. The denture set of claim 1, wherein the teeth, viewed from a buccal or labial direction, have a tooth center line that is disposed perpendicular to an occlusion line (1).

4. The denture set of claim 1, wherein the at least three contact points (5) provided in the fossa are disposed on a spherical surface (10).

5. The denture set of claim 1, wherein tripodal ridges (17) and/or marginal ridges (33) are provided in the fossa, and the at least three contact points (5) are disposed on inclines of the tripodal ridges and/or marginal ridges.

6. The denture set of claim 1, wherein, adjacent to tripodal ridges of said fossa and originating at the at least three contact points (5), concavities (12) are provided in a direction of a laterotrusion or protrusion or lateroprotrusion or mediotrusion or surtrusive retrusion motion of one of said first or second jaw.

7. The denture set of claim 1, wherein a ratio of the surface area formed by a circumference of the at least one first and second tooth to the inside surface area of an occlusal table (13) is 55-65%.

8. The denture set of claim 1, wherein a marginal ridge contact (16) is provided on a mesial and/or distal marginal ridge of the tooth.

9. The denture set of claim 1, wherein a distal surface of said at least one first and second tooth is a shaped, convex surface (15), and wherein a mesial surface of an adjacent tooth is a concave fitting surface (14).

10. The denture set of claim 1, wherein an upper first premolar of an upper jaw buccal-mesially has a concavity (34) disposed between a tripodal ridge and a marginal ridge, wherein said concavity interacts with a guide face (35) provided buccal-distally on a canine tooth or a first premolar of a lower jaw.

11. The denture set of claim 1, wherein on a working side, molars of an upper jaw have first guide faces (32) on buccal inclines that interact with second guide faces (32) provided on a buccal outer surface of the molars of a lower jaw, and wherein third guide faces that interact with fourth guide faces (32) provided on palatal inclindes of the molar of the upper jaw are disposed on a balance side of the buccal inclines of the molars of the lower jaw.

12. The denture set of claim 1, wherein a first premolar of an upper jaw has a buccal-mesial concavity disposed between a tripodal ridge and a marginal ridge, wherein said concavity interacts with a guide face provided distal-palatally on the canine tooth of a lower jaw.

13. A denture set of prefabricated teeth for incisors and/or canines, having at least one first tooth selected from a group of teeth provided for a first jaw, and at least one second tooth selected from a group of antagonists provided for a second jaw, wherein the at least one first tooth has at least one first contact points (6, 7) on surfaces disposed facing the antagonists, wherein said at least one second tooth comes into contact with said at least one first contact point, wherein said at least one contact point (6, 7) is disposed on a sagittal compensation curve (2) and a transversal curve (3), and wherein said sagittal compensation curve (2) and said transversal compensation curve (3) are determined by a motion at least one condyle of a mandible (25).

14. The denture set of claim 13, wherein the teeth have two contact points.

15. The denture set of claim 13, wherein an upper incisor lingually has a guide face (8) extending in an incisal direction from at least one second contact point (6a).

16. The denture set of claim 13, wherein a lower incisor has a surface (30) labially adjoining a cutting edge, wherein said surface is inclined by an angle of 20°

-45°

to an approximal tooth center line (28).

17. The denture set of claim 13, wherein an upper incisor has a surface (27) palatally adjoining the cutting edge, wherein said surface is inclined at an angle of 20°

-45°

to an approximal tooth center line (28).

18. The denture set of claim 13, wherein a distal surface of said at least one first and second tooth is shaped, convex surface (15), and wherein a mesial surface of an adjacent tooth is a concave fitting surface (14).

19. The denture set of claim 13, wherein the teeth, viewed from a buccal or labial direction, have a tooth center line that is disposed perpendicular to an occlusion line (1).
