Of the 23 measurements tested for each procedure, one [(Ii to NB (mm)] showed better agreement with hand-tracing when the advanced features were used, 20 showed good agreement with hand-tracing for both basic and advanced features, while two (AB on FOP and Ii to A/Pog) showed poor intra-user reproducibility. Hand-tracing took a significantly longer time (P < 0.001) than both the basic and advanced features. The advanced features took a significantly longer time (P < 0.001) than the basic features.
Both basic and advanced features showed good measurement agreement with the hand-tracing technique. The use of the basic features minimizes the time requirements for analysis. A computerized tracing technique, which consists of either basic or advanced feature, can be regarded as less time consuming and equally reliable to hand-tracing as far as cephalometric measurements are concerned.
