Area of Science:

  • Dentistry
  • Orthodontics
  • Oral and Maxillofacial Radiology

Background:

  • A 15-year-old patient presented with significant dental anomalies.
  • The patient had no hereditary or clinical disease history.
  • The case involved 11 impacted teeth, including two supernumerary teeth.

Observation:

  • The patient exhibited extruded and lingually inclined lower incisors.
  • An anteriorly inclined palatal plane and an extremely large curve of Spee were noted.
  • Significant dental crowding within the alveolar bone was observed.

Findings:

  • Detailed positional relationships between each impacted tooth and adjacent teeth were analyzed.
  • Three-dimensional (3D) computed tomography (CT) imaging was utilized for precise visualization.

Related Experiment Videos

  • The study identified complex spatial arrangements of the impacted and supernumerary teeth.

    • Implications:

    • 3D CT imaging is crucial for diagnosing complex impactions and supernumerary teeth.
    • Understanding tooth positional relationships aids in treatment planning for orthodontic and surgical interventions.
    • This case highlights the importance of advanced imaging in managing severe dental anomalies.
