Arrangement of artificial teeth

  1. 1. ARRANGEMENT OF ARTIFICIAL TEETH Dr. Sajjad Hussain Demonstrator Islamic International Dental College Islamabad
  2. 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. 3. ANTERIOR TOOTH SETUP • MAXILLARY GUIDELINES ON WAX RIMS • Midline on wax rim • Corners of the mouth (canine line) • High lip line
  4. 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. 5. ANTERIOR TOOTH SETUP • MAXILLARY CENTRAL INCISOR • Scoop out wax • Place 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. 6. MAXILLARY CENTRAL INCISOR
  7. 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. 8. MAXILLARY LATERAL INCISOR
  9. 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. 10. MAXILLARY CANINE
  11. 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. 12. MANDIBULAR CENTRAL INCISOR
  13. 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. 14. MANDIBULAR LATERAL INCISOR
  15. 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. 16. MANDIBULAR CANINE
  17. 17. COMPLETED MAXILLARY AND MANDIBULAR ANTERIOR TOOTH SETUP
  18. 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. 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. 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. 21. MAXILLARY FIRST PREMOLAR
  22. 22. POSTERIOR TOOTH SETUP • MAXILLARY 2ND 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. 23. MAXILLARY 2ND PREMOLAR
  24. 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. 25. MAXILLARY FIRST MOLAR
  26. 26. POSTERIOR TOOTH SETUP • MAXILLAY 2ND 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. 27. MAXILLAY 2ND MOLAR
  28. 28. POSTERIOR TOOTH SETUP • MANDIBULAR 1ST 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. 29. MANDIBULAR 1ST PREMOLAR
  30. 30. POSTERIOR TOOTH SETUP • MANDIBULAR 2ND 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. 31. MANDIBULAR 2ND PREMOLAR
  32. 32. POSTERIOR TOOTH SETUP • MANDIBULAR 1ST 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 2nd PM. Buccal and distal cusps higher than other two. – Occlusal contact : mesio buccal cusp occludes in fossa between upper 2nd PM and 1st Molar.
  33. 33. MANDIBULAR 1ST MOLAR
  34. 34. POSTERIOR TOOTH SETUP • MANDIBULAR 2ND 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 1st molar – Occlusal contact : mesiobuccal cusp occludes in fossa between two upper molars.
  35. 35. MANDIBULAR 2ND MOLAR
  36. 36. COMPLETED MAXILLARY AND MANDIBULAR TOOTH SETUP
