Introduction: Successful prosthesis is made in harmony with the stomatognathic system. To fabricate a successful prosthesis the stomatognathic system must be simulated outside the patient's mouth in a mechanical device called articulator. For the aforesaid reason replication of sagittal condylar guidance outside the patients, the mouth is of utmost importance. Aim of Study: To compare sagittal condylar guidance obtained by conventional method and panoramic radiographic tracing in both dentulous and edentulous patients. (1) To determine the condylar guidance on panoramic radiographs in dentate and edentulous subjects. (2) To determine the condylar guidance by the conventional clinical method in both dentate and edentulous patients. (3) To compare the values obtained from panoramic radiographs with the values obtained by conventional techniques. (4) To compare the right side condylar guidance values to the left. Methodology: A total of 20 dentulous and 20 edentulous patients were selected and their sagittal condylar guidance is recorded firstly with conventional method and then with the tracing of orthopantomograph (OPG). Then, these values are compared with each other to find out any significant difference between these two methods. Results: There is no significant difference in sagittal condylar guidance obtained from OPG and protrusive interocclusal record (PIR) method in dentulous and edentulous patients. Conclusion: The radiographic method is a potential alternative to PIR method.
