CAST ANALYSIS

• CAST APART

• CAST IN OCCLUSION

CAST ANALYSIS

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

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 directionInfraversion tooth that has not erupted enough in comparison to adjacent teethSupraversion tooth that has overeruptedTorsiversion rotated tooth or tooth movements around its long axisTransposition when two teeth have exchanged their positions

• Incisor relationship

• Canine relation• Molar relation• Overjet • Overbite• Crossbite• Dental midline

Molar and canine relationship

Space analysis

SPACE REQUIRED

SPACE AVAILABLE

RADIOGRAPHIC METHOD OF SPACE ANALYSIS FOR MIXED DENTITION

X = (y) (x’)/Y’

X = Estimated size of the permanent tooth X’ = Radiographic size of the permanent teethY = The size of the primary mandibular second molar on the cast. Y’ = the radiographic size of the primary molar
