Reliability of fully adjustable, articulators using a computerized analysis

1. Statistical analysis of the graphic data showed no significant difference between the Denar D5A and Hanau 130-21 articulators for the five subjects tested. 2. The average horizontal Gothic arch angle (beta) at incision was 135 degrees. 3. The functional stroke for the subjects was approximately 5 mm. in the incisor region and 2.5 to 3 mm. in each molar region. 4. Both the Denar D5A and Hanau 130-21 articulators adequately reproduced jaw motion for the five subjects tested.
