1. QUANTITATIVE METHOD

2. MALALIGNMENT INDEX [VANKIRK AND PENNELL]
MEASURE
TOOTH DISPLACEMENT AND ROTATIONS
[<1.5mm or > 1.5mm] and [<45° or >45 °]

3. Handicapping labiolingual deviation index by Braker
Measure
Cleft palate[all or none]
Traumatic deviations [all or none]
Overjet[mm]
Overbite[mm]
Mand protrusion [mm]
AOB [mm]
Labiolingual spread [measure tooth displacement by mm]

4. Occlusal feature index by Poulton an Aaronson
Measurement include lower anterior crowding, cuspal interdigitation, vertical overbite and horizontal overjet

5. Malocclusion severity estimate by Grainger
Seven weigted and defined measurement [1] overjet, [2] overbite,[3] AOB, [4] congenitally missing maxillary incisors, [5] first permanent molar relationship,[6] posterior crossbite and [7] tooth displacement [actual or potential]
Six maloccl syndromes were defined as follows
Positive OJ and AOB
Postive OJ, positive overbite, distal molar relationship and posterior crossbite with maxillary teeth buccal to mand teeth
Negative overjet, mesial molar relationship and post crossbite with maxillary teeth lingual to mand tteth
Congenitally missing max inc
Tooth displacement
Potential tooth displacement

6. Occlusal index by Summers
Nine weighted and defined measurement : [1] molar relation [2] overbite [3] OJ, [4] post crossbite [5] post opent bite [6] tooth displacement [7] midline relation [8] max median diastema [9] congenitally missing max inc
Seven malooclusion syndrome were defined as follows
OJ + open bite
Distal molar relation, OJ, overbite, post crossbites, midline diastema and midline shift
Congenitally missing max inc
Tooth displacement [actual + potential]
Post open bite
Mesial molar reation, OJ overbite post crossbite midline diastema midline shift
Mesial molar relation mixed dentition analysis [potential tooth displacement] and tooth displacement

7. Treatment priority index Grainger
Eleven weighted and definded measurement
Upper ant segment OJ
Lower ant segment OJ
Overbite of upper ant over lower ant
Ant openbite
Cingenital absence of in
Distal molar relation
Mesial molar rotation
Post crossbite
Tooth displacement
Gross anomalies

11. ICON The occlusal traits scored Upper and lower segment alignment
Ant vertical r/ship, centerline, impacted teeth, upper and lower buccal segment alignment [Lt and Rt added together], buccal segment anteroposterior r/ship, buccal segment vertical r/ship, crossbite, mssing teeth for any reason [excluding 3rd molar]
Aestheic assessment based on IOTN aesthetic component, OJ in mm, reverse in mm, upper and lower incisor inclination relative to the occlusal plane, overall upper arch crowding/spacing, lip competency
