A comparison of articulator settings obtained by using an electronic pantograph and lateral interocclusal recordings.
Articulator settings were obtained for two subjects 10 times in a 2-week period by using both a lateral interocclusal record technique and a Pantronic pantograph. The ORB and PSS articulator settings obtained from the two techniques were compared and the following conclusions drawn. 1. Over a 2-week period, the variance in the Pantronic pantograph ORB and PSS articulator settings was less than the variance in the setting obtained by using lateral interocclusal records. For the Pantronic pantograph technique, 95% of any ORB settings were within 2.5 degrees of the Pantronic pantograph mean and 95% of any PSS settings were within 1.9 degrees of the Pantronic pantograph mean. For the interocclusal record technique, 95% of the ORB settings made with interocclusal records were within 11.9 degrees of the mean for one subject and 13.4 degrees of the mean interocclusal records setting for the other subject. For the PSS settings, 95% of the interocclusal record settings were within 10.1 degrees of the mean setting for one subject and 11.6 degrees of the mean interoccusal record setting for the other subject. 2. In adjusting the ORB and PSS articulator settings, the maximum potential occlusal errors that may be produced by using the Pantronic pantograph are smaller than the maximum errors that may be produced in using the lateral interocclusal record technique.
