Background: The present in vivo study aims to compare the horizontal condylar guidance
values in edentulous people using a manual tracing of orthopantomogram (OPG) and lateral
cephalogram with the protrusive interocclusal records mounted on a semi-adjustable
articulator.
Materials and method:A total of 50 patients within the age group of 55-75 years, of either
sex were selected according to the inclusion and exclusion criteria and HCG angle was
determined clinically by interocclusal protrusive records mounted in a semi-adjustable
articulator after extraoral gothic arch tracing and compared with HCG angles obtained by
manual tracing of orthopantomogram and lateral cephalogram for each patient.
Results: On comparison between the mean of three methods, the value obtained from lateral
cephalogram was 10.6 degrees greater than mean values obtained from interocclusal
protrusive records and 3.11 greater than OPG values, and mean OPG valueswere 7.51 greater
than interocclusal records, on comparison the p<0.001 which is significant.
Conclusion:Clinical protrusive method for each individual is mandatory to determine
accurate HCG values. Cephalometric tracing of diagnostic radiographs can delineate an idea
about HCG angle before any clinical step.
