| Abstract | ||
| The objectives of this study were to determine and compare the arch perimeter, arch width and vertical arch length in class I normal occlusion and class II malocclusion (division 1 and division 2) in a Kurdish sample of young adults aged 14–25 years. These measurements were taken on 100 study models (50 cases of class I normal occlusion and 50 cases of class II malocclusions). The results showed that (1) Upper and lower arch perimeters of class I normal occlusion were significantly shorter than class II division 1 [at p value= 0.000 , 0.016 ] subsequently ,whereas, no significant difference were found comparing with class II division 2 group[ p value= 0.59 , 0.61] subsequently (2) No differences were found in upper intercanine width in the two different groups of class II malocclusion [p=0.136] and with class I normal occlusion at p> 0.05, (3) upper intermolar width in Class II division 2 were significantly smaller than that in class I normal occlusion [p= 0.000] (4) Lastly, the vertical maxillary arch length in Class II division 1 was significantly larger than Class II division 2 at p<0.05 . | ||
