Abstract:
A study of 50 cases treated with the Fränkel appliance shows significantly greater increase in bigonial width and related decrease in frontofacial taper as seen in the P-A cephalometric view than in comparable cases treated with Edgewise therapy or in untreated norms from the Bolton and FOR studies.
