A systematic review of soft-to-hard tissue ratios in orthognathic surgery. Part IV: 3D analysis─is there evidence?

The planning of orthognathic surgery has traditionally been performed using two-dimensional (2D) technology and 2D cephalograms. Most studies have been conducted using this methodology, whereby the soft tissue response to bone movements under different surgical conditions can be determined (San Miguel de Moragas et al., 2014; San Miguel de Moragas et al., 2015; Olate et al., 2016); however, the same articles have shown variability related to surgical technique in 2D analyses.
