Abstract

BackgroundThe purpose of this study was to analyze the relationship between body posture and sagittal dental overjet in children before and after early orthodontic treatment with removable functional orthodontic appliances.MethodsAngle Class II patients (mean age 8.2 ± 1.2 years; 29 males and 25 females) with a distinctly enlarged overjet (> 9 mm) were retrospectively examined regarding body posture parameters before and after early orthodontic treatment. In addition, changes in overjet were investigated with the aid of plaster models. Forms of transverse dysgnathism (crossbite, lateral malocclusions) and open bite cases were excluded. Body posture parameters kyphosis, lordosis, surface rotation, pelvic tilt, pelvic torsion and trunk imbalance were analyzed by means of rasterstereographical photogrammetry to determine, if the orthodontic overjet correction is associated with specific changes in posture patterns.ResultsIn nearly all patients an overjet correction and an improvement regarding all body posture and back parameters could be noted after early orthodontic treatment. Overjet reduction (− 3.9 mm ± 2.1 mm) and pelvic torsion (− 1.28° ± 0,44°) were significantly (p < 0.05) and moderately correlated (R = 0.338) with no significant associations found for the other posture and back parameters (p > 0.05).ConclusionOverjet reduction during early orthodontic treatment may be associated with a detectable effect on pelvic torsion.

Highlights

The purpose of this study was to analyze the relationship between body posture and sagittal dental overjet in children before and after early orthodontic treatment with removable functional orthodontic appliances
From T1 to T2 mean correction of overjet was − 3.9 mm ± 2.1 mm. This led to a mean overjet of 7.2 mm ± 2.1 mm at the end of early orthodontic treatment T2 (Table 1)
This study shows a moderate correlation between sagittal incisor overjet and orthopedic parameters with a significant correlation observed for a reduced overjet and pelvic torsion (p < 0,012)

Summary

Introduction

The purpose of this study was to analyze the relationship between body posture and sagittal dental overjet in children before and after early orthodontic treatment with removable functional orthodontic appliances. Some studies have shown some, albeit sometimes minor, influences [2,3,4,5,6], while other studies have found no impact of orthodontics on body posture [7,8,9,10,11] The subject of these studies becomes increasingly more important considering interdisciplinary treatment combining orthopedics and orthodontics [4]. Treatment in children with severe malocclusion, especially of Angle Class II type, could prevent incisor trauma, and have a positive influence on potential orthopedic malformations [13]. Patients with an asymmetry of the jaw should undergo interdisciplinary treatment [5]
