This case report details the successful nonsurgical treatment of a 9-year-old girl's severe anterior open bite and Class II malocclusion. The therapy effectively addressed significant facial discrepancies, reducing protrusion and closing the open bite.

Area of Science:

  • Dentistry
  • Orthodontics
  • Pediatric Dentistry

Background:

  • Class II malocclusion and anterior open bite are common orthodontic issues.
  • Dummy sucking is a potential etiological factor in malocclusion development.
  • Early intervention is crucial for managing complex dental and facial discrepancies in children.

Observation:

  • A 9-year-old female presented with a 9 mm anterior open bite, 8 mm overjet, and transverse maxillary deficiency.
  • The patient exhibited a convex facial profile with procumbent lips.
  • A history of prolonged dummy sucking was noted as a contributing factor.

Findings:

  • Nonsurgical orthodontic therapy was elected as the treatment of choice.
  • The treatment aimed to reduce lip protrusion and achieve anterior bite closure.
