A computer program that uses cephalometric analyses for determining the patient’s occlusal vertical dimension has recently been introduced. Data generated from this computer implies changes in incisal-pin position for articulated casts. This study evaluated the accuracy of this vertical-dimension program using 24 completely dentate, white male subjects with clinically acceptable occlusal vertical dimensions. A cephalometric radiograph was made, and measurements from the tracing were entered into the computer for analysis. Recommended incisal-pin changes ranged from -11 to +25.3 mm, with a mean change of 8.4 mm for all methods tested. These results showed a low correlation with each subject’s clinically determined occlusal vertical dimension.
