| Abstract | ||
| This study was conducted to detect the greater amount of anterior crowding whether in the upper or lower dental arch in either male or female in different malocclusion using exocad system on digital model. Sample of 30 subjects (15 male, 15 female) with age range (14-18) years old, study model for each subject for upper and lower arch scanned by using MeditIdentica Blue Scanners after Exocad software used to measure intermolar (IMD), intercanine (ICD) and little's irregularity index (LII) in present study. Shows wide range of variation in IMD, ICD and LII, female sample shows wider arch in molar and canine region in cl III malocclusion at both upper and lower dental arches (49.45mm and 45.63mm respectively), whereas male data showed greater IMD found in CLI malocclusion (56.54mm) in the upper arch. Results indicating LII in female group with CLI malocclusion severe anterior crowding was found in the lower arch (13.13mm), whereas the least amount of anterior crowding was found in the upper arch of CLII malocclusion (3.59 mm), while in the lower arch well aligned anterior teeth with minimal crowding was found in CLIII malocclusion (3.14mm), with highly significant differences between groups for both dental arches (P> 0.01). In male group, the results of LII were different as the most anterior crowding was found in CLII malocclusion in both upper and lower dental arches (11.7mm and 9.36mm respectively), whereas the minimal anterior crowding was found in CLIII in the lower and upper dental arches (3.74mm and 8.57mm respectively), with significant differences (P> 0.01). Finding establish that the crooking of incisors its dominant character in female male group in the mandibular arch with the CL I malocclusion, while In male group severe crowding exist in the maxillary arch of CL II malocclusion patients. | ||
