Reliability of manual vs. digital plotting

Orthodontic diagnosis is based on cephalometric analysis. Initially, this analysis was performed manually, until digital programmes for cephalometric analysis were introduced. Purpose: The aim of this study was to compare the manually plotted results with those plotted digitally and to test the reliability of the digital system. Materials and methods: The study was carried out using a universe of 70 cephalometric tracings belonging to patients from the UCSG orthodontic clinic in semester A-2015. Two types of diagnosis were analysed: skeletal class by means of Wits, Steiner and Ricketts' facial convexity analysis; and facial growth by means of Ricketts' compressed analysis.
