Adolescent overbite changes are minimal but vary significantly. Mandibular skeletal changes, particularly vertical growth, are key drivers, suggesting targeted orthodontic interventions.

Area of Science:

  • Dentistry
  • Orthodontics
  • Human Growth and Development

Background:

  • Overbite is a crucial dental measurement.
  • Adolescent growth significantly influences craniofacial development and occlusion.

Purpose of the Study:

  • To investigate the multidimensional factors affecting overbite changes during adolescence.
  • To develop a predictive model for overbite alterations.

Main Methods:

  • Longitudinal cephalometric analysis of 181 untreated adolescents (ages 10-15).
  • Measurement of maxillary and mandibular vertical displacements, and incisor vertical changes.
  • Multiple regression analysis to model overbite determinants.

Main Results:

  • Overbite showed minimal average change (0.2 mm) but wide individual variation.

  • Mandibular skeletal changes were the most significant factor influencing overbite.
  • Vertical mandibular growth was more impactful than mandibular rotation.

    • Conclusions:

    • Understanding the multivariate nature of overbite changes is essential.
    • Orthodontic treatments targeting key mandibular components may enhance efficacy.
