Summary
Clear aligner orthodontic treatment may influence body posture, affecting spinal alignment. Studies found correlations between aligner use and changes in kyphotic, upper thoracic, and pelvic inclination after six months.
Area of Science:
- Orthodontics
- Biomechanical Analysis
- Posture Assessment
Background:
- The relationship between malocclusions and body posture remains debated.
- Rasterstereography enables 3D spine reconstruction via back surface analysis.
- Limited research exists on rasterstereographic changes during orthodontic treatment.
Purpose of the Study:
- To investigate potential correlations between orthodontic treatment and body posture.
- To assess the impact of clear aligners on spinal parameters.
Main Methods:
- Compared rasterstereographic values of 15 untreated patients with 15 clear aligner patients.
- Evaluated parameters including kyphotic angle, lordotic angle, upper thoracic inclination, and pelvic inclination.
- Data collected at baseline and after 1, 3, and 6 months.
Main Results:
- Significant correlations were observed between the Kyphosis Angle, Upper Thoracic Inclination, and Pelvic Inclination and body posture.
- These correlations emerged after 6 months of clear aligner treatment.
Conclusions:
- Clear aligner occlusal coverage may influence body posture.
- Effects extend to both upper and lower spine sections.
