Questions and Answers

What is the primary reason orthodontic treatment may not be practical for some patients?

  • Insufficient alveolar bone to support extruded teeth
  • Poor prognosis of teeth preventing extraction
  • Malposed teeth that cannot be repositioned surgically
  • Lack of teeth for anchorage of the orthodontic appliance (correct)

    • What is the consequence of extruded teeth on the surrounding alveolar bone?

  • The alveolar bone will remain unaffected
  • The alveolar bone will be resorbed apically
  • The alveolar bone will be carried occlusally (correct)
  • The alveolar bone will be augmented

    • Why should all impacted teeth be considered for removal?

  • Because they are equally problematic in edentulous areas or adjacent to abutment teeth (correct)
  • Because they may cause occlusal discrepancies
  • Because they may lead to malpositioning of adjacent teeth
  • Because they are severely malposed

    • What is the purpose of surgically repositioning individual teeth or groups of teeth?
