AbstractThe dental arch form is defined as the shape formed by the configuration of the bony ridge of the jaw. Arch form dimension and variations have been studied by several authors. Consideration of the arch form is of utmost importance, because it is crucial that the arch form should be examined before starting upon the treatment as this gives valuable information about the position into which teeth can be moved if they are to be stable following treatment. Different methods have been developed to describe the dental arch morphology ranging from simple classification of arch shape through combinations of linear dimensions to complex mathematical equations.This study is a cross sectional retrospective study which has been undertaken in a university setting. Case records of 300 class II division 1 malocclusion patients in the age group of 12- 40years were included for the study and an analysis was done on different dental arch forms prevalent in class II division 1 malocclusion. Descriptive statistical analysis was performed for association of arch form with gender, age group of the included records in SPSS software by IBM. Chi- square test was performed,frequency distribution was performed. No significant statistical association between gender and arch form , age group and arch form in class II div 1 malocclusion was seen.
