Objective:To investigation the veracity of orientation on modified upright lateral cephalometric radiographs. Methods:Fifty upright lateral cephalometric radiographs were analysed randomly.Twenty-three subjects,who had standard radiographs, were taken with modified technique. The chracterics both of radiographs were compared. Results:The orientations of porion?FH plane and the superimpositions of left and right gonion point on modified standard radiographs were more veracity. Conclusion:The veracity of orientation on upright lateral cephalometric radiographs can be improved.
