This study details treating skeletal Class II, Division 1 malocclusion in early permanent dentition. Despite vertical growth and some anchorage loss, a balanced profile was achieved through premolar extraction.

Area of Science:

  • Orthodontics
  • Dentofacial Orthopedics

Background:

  • Skeletal Class II, Division 1 malocclusion presents a significant orthodontic challenge.
  • Early permanent dentition offers a critical window for intervention.
  • Vertical facial patterns require careful treatment planning.

Observation:

  • The patient exhibited a vertical facial pattern and lower arch crowding.
  • Extraction of four premolars was performed as part of the treatment.
  • Maxillary anchorage loss and vertical facial development were noted during treatment.

Findings:

  • The orthodontic treatment successfully addressed the skeletal Class II, Division 1 malocclusion.
  • Despite challenges like anchorage loss, a favorable outcome was achieved.
  • The final occlusion and facial profile were deemed well-balanced and aesthetically pleasing.

Implications:

  • Premolar extraction can be an effective strategy for managing complex malocclusions with vertical growth.
  • Careful management of anchorage is crucial in vertically growing patients.
  • Achieving a balanced profile is a key goal in treating Class II malocclusions.
