Abstract

The purpose of this study was to determine the best cut-off point for a linear measurment (A-B difference) projected on True horizontal and Frankfort horizontal plane as a SAGITAL jaw indicatore. In addition, it was to determine the accuracy of this method as well as examining the validity of the test among different facial types. A total of 205 pretreatment lateral cephalograms were selected from those being taken in natural head position (NHP) with no history of orthognatic surgery and craniofacial syndrorns. A combination of 5 measurment was used as gold standard for a comparison to the cut-off points. Results showed that cut-off point of more than 6.5mm (PPV: 75%, NPV: 77%) diasnosed as Cl II malocclusion and those over7mm (PPV: 78%, NPV: 77.5%) for PH and True horizontal reference planes. Those cases with cut off point more than 1mm (PPV: 100%, NPY 88%) diagnosed as Cl III malocclusion, while those over 0mm (PPV: 95%, NPV: 88%) for PH and TH reference planes. Conclusion: The accuracy of this method at best was not more than 88% and most of false negative and false positive cases were those with high angle or - low angle cases.
