Abstract : One of the common problems which must be dealt with in Orthodontics is a transverse malrelationship or buccal crossbite of the posterior teeth. This study was undertaken to determine whether or not individuals with Class II division 1 malocclusion have a narrower maxilla than Class I normal individuals. It is the purpose of this study to measure the upper and lower arch widths in individuals with Class II division 1 malocclusion and with normal occlusion to determine (1) whether or not the upper and lower arches of the Class II division 1 sample are different in size from a normal occlusion control sample and (2) what interrelationship exists between the upper and lower arches in Class II division 1 individuals as compared to the interrelationship in a normal occlusion control sample. An additional purpose was to determine what relationships exist between arch width measurements and measurements of anteroposterior and vertical relationships of the arches.
