Teeth Arrangement

2. Maxillary Central Incisors
Front : long axis parallel to the vertical
axis.
Side :slopes labially at about 14◦.
Occlusal plane : incisal edge is in contact
with occlusal plane.

3. Maxillary lateral incisors
When viewed from
Front : long axis slopes towards midline at
incisal edge.
Side :slopes labially at about 20◦.
Occlusal plane : incisal edge is 1mm short of
Occlusal plane.

4. Maxillarycanine
Front : long axis parallel to the vertical axis.
Side :long axis parallel to the vertical axis.
Occlusal plane : cuspid tip is in contact with
occlusal plane.

5. Mandibular central incisors
When viewed from
• Front : long axis inclines slightly towards
the vertical axis.
• Side : slopes labially.
• Occlusal plane : incisal edge is
0.5-1 mm above the occlusal plane.

6. Mandibular lateral incisors
When viewed from
• Front : long axis inclines towards the
vertical axis.
• Side : slopes labially less than central
incisor.
• Occlusal plane : incisal edge is 0.5-1mm
above occlusal plane.

7. Mandibular canine
When viewed from
Front : long axis inclines towards
the midline.
Side : slopes lingually.
Occlusal plane : cuspid tip is 0.5-
1mm above occlusal plane.

8. Class 1 canine relationship

10. Overjet overbite
Overjet horizontal
overlap is 0.5-1mm.
Overbite is the vertical
overlap and it of about
1-2mm.

11. Posteriors

12. Maxillary 1st premolar
When viewed from
• Front : long axis parallel towards the vertical axis.
• Side : long axis parallel towards the vertical axis.
• Occlusal plane :buccal cusp is in contact with occlusal
plane and palatal cusp is 1mm short of occlusal
plane

13. Maxillary 2nd premolar
When viewed from
• Front : long axis parallel towards the vertical axis.
• Side : long axis parallel towards the vertical axis.
• Occlusal plane : Both buccal cusp and palatal cusp
are in contact with occlusal plane.

14. Maxillary 1st molar
When viewed from
• Front : long axis slopes buccaly.
• Side : long axis slopes distally.
• Occlusal plane : only mesiopalatal cusp in
contact with occlusal plane.

15. Maxillary 2nd molar
When viewed from
• Front : long axis slopes buccaly and more
steeply than the 1st molar.
• Side : long axis slopes distally more steeply
than the 1st molar..
• Occlusal plane : only mesiopalatal cusp is nearest
to occlusal plane.

16. Maxillary teeth set, checked on a
glass plate

17. Mandibular 1st molar
Front : long axis leans lingually.
Side : long axis lean mesially.
Occlusal plane : all cusps are at higher level
than n 2nd premolar, buccal and distal
cusps higher than the other two.
Occlusal contact : the mesiobuccal cusp
occludes n the fossa between upper 2nd
premolar ant 1st molar.

18. Mandibular 1st premolar
Front : long axis parallel towards the vertical axis.
Side : long axis parallel towards the vertical axis.
Occlusal plane : lingual cusp below the horizontal plane, buccal cusp
is 2mm above the occlusal plane.
Occlusal contact : buccal cusp contacts the mesial marginal ridge of
upper first premolar.

19. Mandibular 2nd premolar
When viewed from
• Front : long axis parallel towards the vertical axis.
• Side : long axis parallel towards the vertical axis.
• Occlusal plane : both cusp are 2mm above the occlusal plane.
• Occlusal contact : buccal cusp contacts the fossa between the two upper
premolars.

20. Mandibular 2nd molar
• Front : long axis leans more lingually.
• Side : long axis lean more mesially.
• Occlusal plane : all cusps are at higher level
than 1st molar, buccal and distal cusps
higher than the other two.
• Occlusal contact : the mesiobuccal cusp
occludes n the fossa between the two
upper molars.

22. Carving and polishing.1. Adapt the softened roll of baseplate wax on
the facial surface and extend.
2. Seal the baseplate wax around the neck of
each tooth with a wax spatula.
3. Carve the gingival margins of anterior teeth
with a carver held approximately at 60◦
4. Carve the gingival margins of posterior teeth
by a carver held approximately at 45◦.
5. Use a gas touch to flame the wax surface
taking care not to over heat the gingival
contours. The maxirally waxed denture
shows the gingival contour and the root
forms.
6. Adapt the baseplate wax on lingual surface
of the trial denture and carve.

23. Completed
Teeth arrangement

25. Compensatory curves
The Anteroposterior and lateral curvatures in the alignment
of the occluding surfaces and the incisal edges of the artificial
teeth that are used to develop a balanced occlusion.

26. Curve of spee.
The anatomic curve established by the
occlusal alignment of the teeth, as
projected onto the median plane,
beginning with the cusp tip of mandibular
canine and following the buccal cusp tips
of the premolars and molars and
continuing with the anterior border of the
mandibular ramus and ending with the
anterior most portion of the mandibular
condyle.

27. Curve of wilson
It is used to arrange the
molars
The lower teeth are inclined
lingually, giving prominence to
the buccal cusps and brining
them into heavy occlusal
contact with the upper buccal
cusp during lateral movements
on working side

28. Curve of monsoon
Curve of occlusion in
which each cusp and
incisal edge touches a
segment of a surface of a
sphere 8 inches in
diameter with its centre
in the region of the
glabella

significant dental innovation specially for the older generation…!!
