Cephalometric changes in growing patients with increased vertical dimension treated with cervical headgear

Area of Science:

• Orthodontics
• Craniofacial Development

Background:

• Increased vertical dimension in Class II malocclusions presents treatment challenges.
• Cervical headgear is used to control vertical facial growth.

Purpose of the Study:

• To evaluate cephalometric changes in patients with increased vertical dimension treated with cervical headgear.
• To compare these changes with an untreated control group.

Main Methods:

• Retrospective study of 20 Class II patients (increased vertical dimension) treated with cervical headgear.
• Control group of 21 Class II patients (increased vertical dimension) with no treatment.
• Cephalometric analysis at baseline (T1) and post-treatment/observation (T2).

Main Results:

• No significant worsening of vertical dimension or overbite in the treated group.
• Significant increase in facial angle, indicating counterclockwise mandibular rotation in the treated group compared to controls.
• Maxillary clockwise rotation and distal displacement observed post-treatment.

Conclusions:

• Cervical headgear treatment did not significantly alter the vertical dimension.
• Significant mandibular counterclockwise rotation and maxillary clockwise rotation/distal displacement occurred.
• Treatment appears beneficial for managing vertical dimension in Class II malocclusions.
