Summary:CADIAX® is a computer system which measures and analyzes three dimensional condylar movements. The upper and lower facebow of CADIAX® was fixed on the simulator, and was tested for its accurancy and conditions of measuring on sagittal movements. Accuracy was evaluated by measuring errors and linearity of 10mm straight lines at various conditions; that is, improved upper facebow to hold the parts tightly, measuring area on the flag, and compression rate of styli. The findings are as follows. 1. Straight lines of 10mm produced large measuring errors in all conditions, ranging from 1.31mm to 2.08mm (mean 1.55mm). The record at the center area of the flag showed a significantly large error compared to the anterior and posterior area of the flag. 2. The best linearity of a 10mm straight line was recorded with 2mm compressed styli and the fixed upper facebow. 3. The results show that CADIAX® requires a solid upper facebow for an accurate record. They also suggest that CADIAX® is its present form is inadequate for quantitative analysis.
