ABSTRACTPurpose:Horizontal condylar guidance is an important factor to be considered during complete denture fabrication, which is governed by the patient. This study was carried out to evaluate the effect of three different anterior reference points on horizontal condylar guidance, to provide the most accurate anterior reference point.Materials and Methods:Facebow records were recorded on 13 completely edentulous subjects and transferred to the semiadjustable articulator using three different anterior reference points. A 6 mm protrusive interocclusal record was made to program the semiadjustable articulator. The horizontal condylar guidance values were obtained for the right and left sides separately, using each anterior reference point. The diagnostic panoramic radiographic tracings were done to obtain right and left horizontal condylar guidance. The data were tabulated and statistically analyzed using paired t-test.Results:The horizontal condylar guidance obtained on the right side using orbitale and the superior annular notch was significantly different from the radiographic values (P < 0.05), and the difference was not significant for the inferior annular notch (P = 0.42). While on the left side, the horizontal condylar guidance values obtained using the superior annular notch were significantly different (P < 0.05), and those for orbitale and inferior annular notch (P = 0.23) did not differ significantly from the radiographic values.Conclusion:When a face bow transfer was done, the three anterior reference points showed different condylar guidance values. However, the values were significantly closer to the radiographic values, when the orbitale and the inferior annular notch were chosen as an anterior reference points.
