    This study investigated headgear-reactivator treatment for Class II, division 1 malocclusions. While improving sagittal jaw relationships, it caused significant tooth movement, with no vertical changes observed.

    Area of Science:

    • Orthodontics
    • Craniofacial Growth

    Background:

    • Class II, division 1 malocclusion is a common dental issue.
    • Effective treatment strategies are crucial for growing patients.

    Purpose of the Study:

    • To evaluate the efficacy of a headgear-reactivator combination appliance.
    • To assess skeletal and dental changes in Class II, division 1 patients.

    Main Methods:

    • Sixty-six growing patients with Class II, division 1 malocclusion were treated.
    • A headgear-reactivator appliance with a mandibular advancement mechanism was used.
    • Lateral cephalograms were analyzed before and after treatment.

    Main Results:

    • Significant improvement in the sagittal jaw relationship was observed.

  • Considerable retroclination of maxillary incisors and proclination of mandibular incisors occurred.
  • No significant changes in the vertical skeletal dimension were noted.

    • Conclusions:

    • The headgear-reactivator combination effectively improves sagittal jaw discrepancies.
    • Orthodontic treatment with this appliance can lead to substantial incisor movement.
    • Vertical facial growth remained largely unaffected by this treatment approach.
