The International Journal of Prosthodontics
|October 2, 2025
Summary
Comparing three methods for measuring sagittal condylar inclination (SCI), panoramic radiography and electronic axiography showed strong correlation. Interocclusal wax records offered moderate agreement and are valuable for dentate patients.
Area of Science:
- Dental biomechanics
- Craniomandibular anatomy
Background:
- Sagittal condylar inclination (SCI) is a crucial parameter in understanding mandibular movement and TMJ function.
- Accurate measurement of SCI is essential for prosthodontic treatment planning and diagnosis of TMJ disorders.
Purpose of the Study:
- To compare sagittal condylar inclination (SCI) values derived from interocclusal wax recordings, panoramic radiography, and electronic axiography (Cadiax-Compact 2).
Main Methods:
- Fifteen adult participants underwent SCI assessment using three distinct techniques: protrusive interocclusal wax records, panoramic radiography, and Cadiax-Compact 2 electronic axiography.
- Statistical analysis included paired t-tests for side-to-side comparison and Pearson correlation to evaluate inter-method agreement (p<0.05).
Main Results:
- No significant differences were found between right and left condylar SCI values across all methods.
- Panoramic radiography and Cadiax-Compact 2 exhibited the highest correlation, indicating strong agreement.
- Interocclusal recordings showed moderate correlation with the other methods and yielded the lowest SCI values.
Conclusions:
- Panoramic radiography and Cadiax-Compact 2 demonstrate high correlation for SCI measurement.
- Interocclusal wax recordings provide moderate agreement and are recommended for dentate patients due to functional movement considerations.
- Panoramic radiography serves as a practical alternative for patients with limited neuromuscular control or gag reflex issues.

01:25Relative Motion Analysis using Rotating Axes
Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it instrumental in...

Consider a crane whose telescopic boom rotates with an angular velocity of 0.04 rad/s and angular acceleration of 0.02 rad/s2. Along with the rotation, the boom also extends linearly with a uniform speed of 5 m/s. The extension of the boom is measured at point D, which is measured with respect to the fixed point C on the other end of the boom. For the given instant, the distance between points C and D is 60 meters.

01:15Unsymmetric Bending - Angle of Neutral Axis
Unsymmetrical bending occurs when a structural member is subjected to bending moments in a plane that does not align with the member's principal axes. This scenario typically arises in beams and other structural components when loads are applied at non-ideal angles, introducing complexities in stress analysis.
When a bending moment is applied at an angle θ concerning the vertical axis of a symmetrical member, it can be resolved into components along the member's principal centroidal axes. The...

Analyzing a supported beam under unsymmetrical loadings is essential in structural engineering to understand how beams respond to varied force distributions. This analysis involves calculating the deflection and identifying points where the slope of the beam is zero, which are crucial for ensuring structural stability and functionality.
The first moment-area theorem determines the slope at any point on the beam. This theorem indicates that the change in slope between two points on a beam...

01:25Design Example: Traverse Angle Computations
Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...
01:12Adjusting a Traverse
In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles.
