Abstract

The invention relates to a set of pre-manufactured teeth, consisting at least of one first molar or premolar selected from a group of molars or premolars provided for one jaw, and at least of one second premolar or molar selected from a group of antagonists provided for the other jaw, at least three centric contact points being provided in each case in the fossa of a premolar or molar, a stamp cusp of the antagonist coming to rest on the contact points in the position of intercuspation, the contact points being disposed on a compensation curve defined by the movement of the jaw condyles, the centric contact points each lying on a spherical sector, and abrasions being disposed in at least one movement track without breaking up the punctiform contacts.

Claims

1. A set of pre-manufactured teeth, comprising at least one of a first molar and a premolar selected from a pluraliry of molars or premolars provided for one jaw, and at least one of a second premolar and a molar selected from a plurality of antagonists provided for the other jaw, wherein at least three centric contact points being provided in each of a fossa of a premolar or a molar, a stamp cusp of the antagonist coming to rest on the contact points in the position of intercuspation, and the contact points being disposed on a compensation curve defined by the movement of the jaw condyles, such that the centric contact points each lie on a spherical sector, and abrasions are disposed in at least one movement track without breaking up at least one of the punctiform contacts.

2. The set of teeth as claimed in claim 1, wherein an inclination of the abrasion surfaces on the mediotrusion side is between about 3 to about 7 degrees, less than on the laterotrusion side.

3. The set of teeth as claimed in claim 2, wherein the inclination of the abrasion surfaces of adjacent teeth decreases sequentially from anterior to posterior.

4. The set of teeth as claimed in claim 3, wherein the sequential decrease is between about 3 to about 7 degrees.

5. The set of teeth as claimed in claim 1, wherein an inclination of the abrasion surface of a molar 7 on the mediotrusion side is between about 20 and about 27 degrees.

6. The set of teeth as claimed in claim 1, wherein the inclination of the abrasion surface of a molar 7 on the laterotrusion side is between about 25 to about 32 degrees.

7. The set of teeth as claimed in claim 1 further comprising one or more premolars or molars 4, 5, 6 and 7, wherein the inclination of the abrasion surfaces is provided as follows:

Tooth Inclination of abrasion surfaces on the mediotrusion side laterotrusion side 4 40°

45°

5 35°

40°

6 30°

35°

7 25°

30°

8. The set of teeth as claimed in claims 1, wherein the abrasions are disposed in the movement tracks of latero-protrusion, immediate side shift and retrusive surtrusion.
