Background and Aim: This study evaluated the reliability of two interocclusal recording materials with panoramic radiographs to measure sagittal condylar guidance in edentulous subjects. Material and methods: The study comprised 30 edentulous subjects. The protrusive interocclusal records were made at the jaw relation stage using bite registration paste and Plaster of Paris for all the subjects to program the Semi-adjustable articulator, and the condylar guidance values on the right and left sides were recorded. Digital orthopantomography was taken for all the subjects and traced, and the values obtained were compared with those obtained by the protrusive interocclusal record. The condylar guidance values obtained by the various procedures were tabulated and subjected to an independent t-test and Pearson's correlation test. Results: The results showed a statistically significant positive correlation (P < 0.0001) between clinical protrusive interocclusal records (polyvinyl siloxane, Plaster of Paris) and panoramic radiographic sagittal condylar guidance values. Conclusions: Within the study's limitations, the condylar guidance values obtained from the panoramic radiographic tracing can be used to calculate the mean horizontal condylar guidance in completely edentulous patients. These values can also be used to program semi-adjustable articulators, avoiding the cumbersome process of obtaining a protrusive interocclusal record.
