Summary
Computed tomographic (CT) three-dimensional analysis offers superior anatomical detail compared to model analysis for diagnosing occlusal plane tilting in facial asymmetry. This advanced CT imaging aids in identifying individual anatomical variations, crucial for severe craniofacial asymmetry cases.
Area of Science:
- Dentistry
- Medical Imaging
- Orthodontics
Background:
- Facial asymmetry presents diagnostic challenges in evaluating occlusal plane tilting.
- Accurate assessment of occlusal plane tilting is crucial for effective treatment planning in orthodontics and craniofacial surgery.
Purpose of the Study:
- To compare computed tomographic (CT) three-dimensional analysis with traditional model analysis as a diagnostic aid for occlusal plane tilting in patients with facial asymmetry.
- To evaluate the utility of CT three-dimensional analysis in identifying individual anatomical variations.
Main Methods:
- Ten patients with facial asymmetry underwent three-dimensional CT scans, plaster cast analysis, and two-dimensional cephalometric analysis.
- Measurements of occlusal plane tilting were taken using three-dimensional CT, plaster models (on an articulator), and cephalograms.
- Quantitative data from each method were compared to assess concordance and identify discrepancies.
Main Results:
- Quantitative measurements of occlusal tilting were similar across all three methods.
- Three-dimensional CT provided a more comprehensive representation of individual anatomy, reducing interpretative challenges.
- CT analysis proved effective in detecting specific anatomical variations relevant to occlusal plane tilting.
Conclusions:
- Three-dimensional CT analysis is a valuable tool for diagnosing occlusal plane tilting in facial asymmetry.
- Its ability to accurately depict individual anatomical variations makes it particularly useful for complex craniofacial cases.
- CT three-dimensional analysis can enhance diagnostic accuracy and aid in treatment planning for severe craniofacial asymmetry.

01:29Three-Dimensional Analysis of Strain
Three-dimensional strain analysis is crucial for understanding how materials deform under stress, particularly in elastic, homogeneous materials. This method employs principal stress axes to simplify complex stress states into more understandable forms. Subjected to stress, a small cubic element within a material either expands or contracts along these axes, transforming into a rectangular parallelepiped. This transformation effectively illustrates the material's deformation. The principal...
01:30Three-Dimensional Force System:Problem Solving
A three-dimensional force system refers to a scenario in which three forces act simultaneously in three different directions. This type of problem is commonly encountered in physics and engineering, where it is necessary to calculate the resultant force on the system, which can then be used to predict or analyze the behavior of the object or structure under consideration.
To solve a three-dimensional force system, first resolve each force into its respective scalar components. Do this using...

01:21Plastic Deformations of Members with a Single Plane of Symmetry
When a structural member undergoes plastic deformation due to bending, it is crucial to understand the position of the neutral axis and the stress distribution. This member, characterized by a single plane of symmetry, exhibits a uniform stress distribution, with negative stress above the neutral axis and positive stress below. Notably, the neutral axis does not align with the centroid of the cross-section. This misalignment is typical in cases where the cross-section is not rectangular or...
01:06Body Planes
Body planes in anatomy are imaginary flat surfaces used as reference points to divide the body into sections for anatomical study. These planes are essential for understanding the orientation, relationships, and spatial organization of anatomical structures.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...
