For the two measuring methods of occlusal vertical dimension using Dento-Profile and Willis techniques, four operators having different degrees of skill obtained measurements using these techniques from 20 subjects and these measurements were then compared. It was found that in either case of the techniques used, there were no substantial differences in measurements obtained by the skilled operators.
However, in case of Willis technique, the measurements taken by the other operators showed a considerably great difference from one another. In case of Dent-Profile technique, only a small difference was shown among all the measurements obtained. The above results indicate that the measurement using Dento-Profile technique may allow operators to secure almost the same clinical values, irrespective of the degrees of operators'skill.
