2. ANTERIOR TOOTH SETUP MAXILLARY GUIDELINES ON CAST Center of incisive papilla Line drawn along midline of the cast through incisive papilla A perpendicular line drawn to above line through center of incisive papilla till land area (corresponds to canine placement)

3. ANTERIOR TOOTH SETUP MAXILLARY GUIDELINES ON WAX RIMS Midline on wax rim Corners of the mouth (canine line) High lip line

4. ANTERIOR TOOTH SETUP MANDIBULAR GUIDELINES Line drawn through the center of anterior ridge till land area – tells position of anterior teeth. Line drawn through center of posterior ridge and middle of retromolar pads – tells position of posterior teeth.

5. ANTERIOR TOOTH SETUP MAXILLARY CENTRAL INCISOR Scoop out wax P lace the central incisor such that: Front : Its long axis is parallel to vertical axis Side : It slopes labially about 15° Occlusal plane : Its incisal edge contacts with occlusal plane (lower wax rim).

6. MAXILLARY CENTRAL INCISOR

7. ANTERIOR TOOTH SETUP MAXILLARY LATERAL Scoop out wax Place the tooth such that when viewed from: Front : Long axis leans slightly mesial at incisal edge. Side : It slopes labially about 20°. Occlusal plane : Incisal edge is parallel but 1-2mm short of occlusal plane.

8. MAXILLARY LATERAL INCISOR

9. ANTERIOR TOOTH SETUP MAXILLARY CANINE Scoop out the wax Place the canine such that when viewed from: Front : long axis parallel to vertical axis Side : long axis parallel to vertical axis Occlusal plane : cusp tip touches occlusal plane

10. MAXILLARY CANINE

11. ANTERIOR TOOTH SETUP MANDIBULAR CENTRAL INCISOR Scoop out wax Place tooth such that when viewed from: Front : long axis slightly inclines towards vertical axis Side : slopes labially Occlusal plane : incisal edge is 0.5-1mm above occlusal plane

12. MANDIBULAR CENTRAL INCISOR

13. ANTERIOR TOOTH SETUP MANDIBULAR LATERAL INCISOR Scoop out wax Place the tooth such that when viewed from: Front : long axis inclines towards vertical axis Side : slopes labially less than central incisor Occlusal plane : incisal edge 0.5-1mm above occlusal plane.

14. MANDIBULAR LATERAL INCISOR

15. ANTERIOR TOOTH SETUP MANDIBULAR CANINE Scoop out wax Place the tooth such that when viewed from: Front : long axis is inclines towards midline Side : slopes lingually Occlusal plane : cuspal tip is 0.5-1mm above occlusal plane.

16. MANDIBULAR CANINE

17. COMPLETED MAXILLARY AND MANDIBULAR ANTERIOR TOOTH SETUP

18. POSTERIOR TOOTH SETUP MAXILLARY GUIDELINES A line drawn is drawn on maxillary occlusal rim from the mid point of lateral incisor to the tuberosity . This line represents the palatal cusps of upper posterior teeth.

19. POSTERIOR TOOTH SETUP MANDIBULAR GUIDELINES A line is drawn on lower occlusal rim corresponding to the center to the alveolar ridge that extends from cuspal tip of canine to the land area posterior to retromolar pad. This line represents the central groove of lower posterior teeth.

20. POSTERIOR TOOTH SETUP MAXILLARY FIRST PREMOLAR Scoop out wax Place the tooth such that when viewed from: Front : long axis parallel to vertical axis Side : Long axis parallel towards vertical axis Occlusal plane : buccal cusp touch occlusal plane and palatal cusp is 1mm short of occlusal plane.

21. MAXILLARY FIRST PREMOLAR

22. POSTERIOR TOOTH SETUP MAXILLARY 2 ND PREMOLAR Scoop out wax Place the tooth such that when viewed from: Front : long axis parallel to vertical axis Side : long axis parallel to vertical axis Occlusal plane : both the buccal and palatal cusps are in contact with occlusal plane.

23. MAXILLARY 2 ND PREMOLAR

24. POSTERIOR TOOTH SETUP MAXILLARY FIRST MOLAR Scoop out wax Place the tooth such that when viewed from: Front : long axis slopes buccally Side : long axis slopes distally Occlusal plane : Only mesio -palatal cusp touches occlusal plane

25. MAXILLARY FIRST MOLAR

26. POSTERIOR TOOTH SETUP MAXILLAY 2 ND MOLAR Scoop out wax Place the tooth such that when viewed from: Front : long axis slopes buccally more steeply than first molar Side : long axis slopes distally more steeply than first molar Occlusal plane : none of the cusp touches the occlusal plane, only mesio -palatal cusp is nearest to occlusal plane.

27. MAXILLAY 2 ND MOLAR

28. POSTERIOR TOOTH SETUP MANDIBULAR 1 ST PREMOLAR Scoop out wax Place the tooth such that when viewed from: Front : long axis parallel to vertical axis Side : long axis parallel towards vertical axis Occlusal plane : buccal cusp 2mm above occlusal plane, lingual cusp below occlusal plane Occlusal contact : buccal cusp contacts the mesial marginal ridge of upper first premolar

29. MANDIBULAR 1 ST PREMOLAR

30. POSTERIOR TOOTH SETUP MANDIBULAR 2 ND PREMOLAR Scoop out wax place tooth such that when viewed from : Front : long axis parallel to vertical axis Side : long axis parallel towards vertical axis Occlusal plane : both cusps about 2mm above occlusal plane Occlusal contact : buccal cusp contacts with fossa between two upper premolars

31. MANDIBULAR 2 ND PREMOLAR

32. POSTERIOR TOOTH SETUP MANDIBULAR 1 ST MOLAR Scoop out the wax Place tooth such that when viewed from : Front : long axis lean lingually Side : long axis lean mesially Occlusal plane : all cusps higher than 2 nd PM. Buccal and distal cusps higher than other two. Occlusal contact : mesio buccal cusp occludes in fossa between upper 2 nd PM and 1 st Molar.

33. MANDIBULAR 1 ST MOLAR

34. POSTERIOR TOOTH SETUP MANDIBULAR 2 ND MOLAR Scoop out wax Place tooth such that when viewed from: Front : long axis leans more lingually Side : long axis leans more mesially Occlusal plane : all cusps higher than 1 st molar Occlusal contact : mesiobuccal cusp occludes in fossa between two upper molars .
