title: Observations on the use of the Denar pantograph and articulator.
abstract: An investigation was undertaken to determine the reproducibility of articular settings from graphic records of simulated mandibular movement using the Denar pantograph and the Denar D4-A articulator. The results of the study showed that most of the articulator adjustments were reproducible with a reasonable degree of accuracy, although not quite to the extent one would hope for. The rear-wall and top-wall adjustments are of questionable value in reproducing mandibular movements with this technique, since the results for these adjustments in the present study were unreliable. However, familiarity with the technique gave better results, as shown in the third experiment. It would, therefore, seem that much of the basis for adverse reports depended upon results obtained by operators with insufficient experience in the technique.
