Evaluating diagnostic performance of three cephalometric vertical parameters.

Objectives: The goal of this research was to see how reliable and valid three selected parameters from different analysis were in detecting the vertical skeletal pattern.

Methods: There were 94 cephalometric x-rays used in all. The vertical skeletal pattern was assessed using the mandibular plane angle by Steiner, Frankfort mandibular angle by Tweed, and facial axis angle by McNamara.
