Introduction: In this study we aim to evaluate accuracy of horizontal condylar guidance values in edentulous patients using preprosthetic diagnostic radiographs. Materials and Methods: A total of 100 CD individuals were considered. HCG angles were determined clinically using protrusive interocclusal records and semi-adjustable articulator after intraoral gothic arch tracing. Radiographically, it was taken by cephalometric tracing of OPG and lateral cephalogram. Results: In our study shows mean HCG ± standard deviation (SD) of 28.17° ± 5.99° for interocclusal protrusive record while cephalometric tracing method yielded HCG ± SD of 38.95° ± 4.77° and 35.2° ± 4.94° for lateral cephalogram and orthopantomogram, respectively. A statistically significant positive correlation was seenamong these three methods. Conclusion: HCG values from cephalometric tracing of diagnostic radiographs can be used as an aid to the clinical method but cannot be used independently for programming a semi-adjustable articulator.
