Arch Forms among Different Angle Classifications a – Study

The aim of the study was to find out the type of arch form amongst different Angle classifications attending the orthodontic department of Sardar Begum Dental College and Hospital, Peshawar. Consideration of the arch form is of paramount importance, because it is imperative that the arch form should be examined before embarking 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. It was a prospective cross-sectional study carried out on a total of 120 individuals irrespective of gender having Angle’s class I, II or III occlusion. The results revealed that the most prevalent arch form among the individuals of the sample was of the tapered variety i.e., 49.2% irrespective of the Angle classification while ovoid and square arch forms were 2nd and 3rd in the prevalence order i.e., 29.2% and 21.2% respectively. The study emphasizes that consideration should be given to the arch form specific for the particular individual.
