Evaluation of Arch Widths among Adults with Class I spacing and Class I Crowding Malocclusion

Abstract

Objective: To test the hypothesis that there is no difference between adults with Class I spacing (CIS), Class I Crowding malocclusion (CIC). Materials and Methods:   Samples of   40 class I spacing (CIS) patient models   (20 male and 20   female), 40 Class I crowding (CIC) patient models (20 male and 20 female) were selected for the study. Alveolar width, Intercanine width and Intermolar width of  maxillary and    mandibular arches were evaluated. Results: The mean   intercanine, Intermolar and the alveolar width of both the maxilla and mandibular  dental arch of  patients with   spacing  were increased when compared to patients   with crowding. The mean comparision based on gender   revealed that among the male patients with crowding showed an  increased  intercanin, Intermolar and an increase   alveolar width when compared to female with crowding in both  maxillary and madibular arch. Among the individual with spacing female patients had an increased maxillary intermolar width and increased alveolar width of both maxillary and  mandibular dentition when compared to Male patients with spacing. Conclusion: The results of this study suggest that patient models with Class I skeletal and dental Spacing showed an increase in the arch width when compared to Class I skeletal and dental Crowding patient models.
