CAST ANALYSIS

4. CAST APART
• Arch form
• Arch symmetry
• Teeth present
• Teeth absent
• Crowding
• Spacing
• Buccoversion / linguoversion
• Supraversion / infraversion
• Torsiversion
• Transposition
• Proclined
• Retroclined

5. DEFINITIONS
Buccoversion when the tooth is displaced bodily in
a labial or buccal direction
Linguoversion when entire tooth is displaced in a
lingual or palatal direction
Infraversion tooth that has not erupted enough in
comparison to adjacent teeth
Supraversion tooth that has overerupted
Torsiversion rotated tooth or tooth movements
around its long axis
Transposition when two teeth have exchanged
their positions

8. TRANSPOSITION

9. CAST IN OCCLUSION
• Incisor
relationship
• Canine relation
• Molar relation
• Overjet

16. SPACE REQUIRED
SPACE AVAILABLE

17. RADIOGRAPHIC METHOD OF SPACE ANALYSIS FOR
MIXED DENTITION

18. X = (y) (x’)/Y’
X = Estimated size of the permanent tooth
X’ = Radiographic size of the permanent teeth
Y = The size of the primary mandibular
second molar on the cast.
Y’ = the radiographic size of the primary
molar
