1. TEETH SETUP
BYAZKAH QAZI
ROLL NO# 23

2. Parts of Denture:
 Base
 Teeth

3. SELECTION OF TEETH
1. SHAPE
 Acc to pt ‘s arch form
 Acc to pt’s face
2. COLOUR
3. LENGTH

5. DEFINITION:
“The setup is the arrangement of
artificial denture teeth on denture
base suitable for mouth”

6. SEQUENCE:
 Teeth should be set in definite position which
is determined by following
r/s of tooth to occlusal plane
r/s of tooth to vertical axis
r/s of tooth to one another

12.  Long axis inclines slightly towards the vertical
axis when viewed from front

13. •Slopes labially 15 degree when viewed
from side

14.  Long axis slopes more toward midline when
viewed from front
 Incisal edge is 1mm short of occlusal plane

15. •Slopes labially 20 degree when viewed
from side

16.  Long axis is parallel to vertical axis
 Cusp is in contact with the horizontal plane

19. Anterior teeth

20. 1st premolar
 Long axis is parallel to vertical axis when viewed from the
front or the side
 Palatal cusp is 1mm shorter
 Buccal cusp is in contact with the occlusal plane

21. 2nd premolar

Long axis is parallel with the vertical axis when viewed form the front or
the side
 Both buccal and palatal cusps are in contact with the occlusal plane

22.  Long axis slopes buccally more
 Mesiopalatal cusp is in contact with the occlusal
plane

23.  Long axis slopes buccally from the front
 Slopes Distally from the side

25. Central incisor
 Its long axis inclines slightly towards the vertical axis
when viewed from the front
 Slopes labially when viewed from the side
 Incisal edge is about 2mm above the occlusal plane

26. Lateral incisor
 Its long axis also inclines towards the vertical axis
when viewed form the front
 Slopes labially when viewed form the side
 Incisal edge is about 2mm above the occlusal plane

27. canine
 Long axis leans very slightly towards the midline when
viewed from the front
 Very slightly lingually when viewed form the side
 Cusp is slightly more than 2mm above the occlusal plane

28. anteriors

29. 1st premolar
 Long axis is parallel to the vertical plane
 Lingual cusp is below the horizontal plane and its
buccal cusp about 2mm above it as it contacts the
mesial marginal ridge of the upper first premolar.

30. 2nd premolar
 Long axis also parallel to the vertical plane
 Both cusps are about 2 mm above the
occlusal plane

31. 1st molar
 Long axis leans lingually
 All the cusps are at a higher level above the occlusal plane
 M.b.c of upper lies in m.b.g of lower molar

32. 2nd molar
 Lingual and mesial inclination of the long axis of this
tooth
 Cusps are at a higher level above the occlusal plane
