Comparative Analysis of Sagittal Condylar Inclination by Interocclusal Recordings, Panoramic Radiographs, and
Purpose:
To compare sagittal condylar inclination (SCI) values obtained using three different methods- interocclusal wax recording, panoramic radiography, and computerized axiography (Cadiax Compact 2, Gamma Dental Software 5.1, Gamma Dental).
Materials And Methods:
A total of 15 adults participated in the study. For the interocclusal recording, SCI was determined using protrusive interocclusal wax records, which were transferred to a semi-adjustable articulator. Panoramic radiographs were obtained, and SCI values were measured by tracing the radiographic images. Extraoral tracings were recorded using a Cadiax Compact 2. After a paraocclusal tray was fixed intraorally, each participant was instructed to perform three protrusive mandibular movements, and the average SCI values were calculated. Paired t test was used to compare the SCI values of the right and left condyles. Pearson correlation analysis was performed to assess the relationship between the values obtained by the different methods, with a significance level set at P < .05.
Results:
No statistically significant difference was observed between right and left condyles for any of the three methods (P > .05). The highest correlation was found between panoramic radiography and Cadiax Compact 2, while moderate correlation was observed between interocclusal recordings and the other two methods. Interocclusal recordings yielded the lowest SCI values, while Cadiax Compact 2 showed the highest.
Conclusions:
While panoramic radiography and Cadiax Compact 2 demonstrated strong correlation, interocclusal records showed moderate agreement and lower SCI values. However, considering the influence of functional movements, interocclusal recordings remain valuable for dentate patients. Nonetheless, panoramic radiography can be a practical alternative in cases with limited neuromuscular control or a strong gag reflex.
