The purpose of this study was to compare the sagittal condylar guidance obtained by the graphic method(pantographic tracing) with that produced by the positional method(check-bite). Ten adults who had normal occlusion and were free of TMJ dysfunction were selected, and the clutches were constructed. At first pantographic survey was performed and the articulator was adjusted with each pantographic recording. And then three protrusive check-bite were taken on the subjects using the polyether$(Lamitec^{(R)})$ on the buccal side of the posterior teeth without the interocclusal record method and the vericheck method was performed with each protrusive check-bite. Sagittal condylar guidances obtained by using the pantograph and Vericheck were compared and analyzed statistically. The results were as follows: 1. The average condylar guidance ankle at 4mm and 7mm from centric relation point on the pantograph $(35.9{pm}1.10^{circ},;32.4{pm}1.55^{circ})$ was statisccally significant(P<0.01). 2. The average condylar guidance angle of the Vericheck was $27.0{pm}3.43^{circ}$. 3. The comparison of the right and left was not statistically significant in all group(P>0.05). 4. The comparison of pantograph and Vericheck was statistically significant in the right and left(P<0.001).
