Alveolar base and dental arch widths with segmental arch measurements.

      Аннотация: Since the size and shape of the arches have considerable implications in orthodontic diagnosis and treatment planning, affecting the space available, dental aesthetics, and stability of the dentition. This study was designed to evaluate and compare dental arches, alveolar bases and segmental arch dimensions of class II division 1, class III malocclusion groups with normal occlusion subjects and to check gender differences and difference between maxillary and mandibular arch widths. Measurements were made on dental casts of 62 subjects aged between 18- 28 years, equally divided between males & females, consisting of 26 normal occlusion, 22 Class II division 1, and 14 Class III malocclusion subjects. Eleven liner measurements were utilized for each dental arch.
