Comparison of some cephalometric indices in skeletal class III with skeletal class I patients

The individual variations in patients with skeletal class III malocclusions affect the cephalometric indices e.g., the curve of cranial base and anteroposterior displacement of nasion and the SN inclination can affect the cephalometric indices such as the ANB angle. The aim of this study was to compare some cephalometric indices in skeletal class III with skeletal class I patients as control group. Samples in this Case-control study were 65 lateral cephalometric radiographs randomly selected before the orthodontic treatment. The samples were divided into two study and control groups with skeletal class III relationship [ANB<1] and skeletal class I relationship [2
