Reliability and accuracy of Centrographic analysis in comparisonwith other superimposition techniques – A Cephalometric study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 10
Abstract
The main objective of the study is to assess and compare the three superimposition methods (Ricketts, Pancherz and Centrographic analysis) and to evaluate the validity of the most reliable and reproducible technique and statistically compare the centrographic analysis with the other two methods to ascertain its relative accuracy. Pre and post treatment lateral cephalograms of thirty non-growing patients with class I malocclusion and first premolar extraction who had been treated successfully with the pre adjusted edgewise appliance were obtained. Pre and post treatment hard and soft tissue measurements were assessed by superimposing the lateral cephalograms on a grid by using Ricketts, Pancherz and Centrographic analysis.The results showed that all the three superimposition methods (Ricketts, Pancherz and Centrographic analysis) compared were reliable. Moreover, no significant difference between the three methods was found in the investigation in all the parameters except for hard tissue pogonion which showed a mild significance which can be explained by the principles of centroid orientation. The study concludes that Centrographic analysis is as reliable as the other superimposition methods like theRicketts and Pancherz. Centroid remains unchanged during growth or treatment and hence Centrographic analysis is consistently reproducible and simply adopted in daily clinical practice.
