“Evaluation of the Accuracy of Measurements Using Digital Versus Manual Tracing Method In Orthognathic Patients” -A Cephalometric Study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 9
Abstract
Aim: The aim of this study was to compare pre and post cephalometric measurements in orthognathic patients acquired with digital tracing software (Dolphin 11.0) with equivalent hand traced measurements in regard to the Reproducibility of each method, Accuracy of various soft/hard tissue landmarks, Accuracy of linear measurements, Accuracy of angular measurements. Materials & Methods: The study consisted of 40 lateral cephalometric radiographs of patients treated by orthognathic surgery. Forty cephalograms were traced both manually and digitally by a single examiner. Three analysis namely Steiner’s, Holdaway and Cephalometrics for Orthognathic surgery (COGS) analysis were assessed. The values were analysed using the Leven’s Test. Results: The results showed no statistical significance in measurements using Steiner’s and COGS analysis but significance was seen in Soft tissue facial angle(0.024) and Sub-nasale to H-line (0.055) P value: <0.05 in Holdaway analysis. Conclusion: Conventional and computerized methods showed consistency in all angular and linear measurements. The computer program Dolphin Imaging 11.0 can be used as a reliable aid in diagnosis, planning, monitoring and evaluating orthodontic treatment both in clinical and research settings.
