Association between cranial structure and choice of bolus hardness in an orthodontic sample
Key Points
This study aims to explore the relationship between cranial structure and the choice of bolus hardness in orthodontic patients.
Analyzed cranial structures in an orthodontic sample
Measured bolus hardness preferences
Assessed intermaxillary and cranial divergences
Soft bolus preference linked to increased intermaxillary divergence
No significant correlation with cranial divergence or mandibular rotation
Suggests a functional-structural feedback loop in choosing softer boluses
Abstract
Soft bolus preference was significantly associated with increased intermaxillary divergence but not with cranial divergence, mandibular rotation, or sagittal skeletal relationship. These findings suggest that patients with intermaxillary hyperdivergent patterns may self-select softer boluses, due to a compensatory functional-structural feedback loop.
