QUANTITATIVE METHOD

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

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]

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

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

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
