Management of class ii division 1 malocclusion Presentation Transcript

  • 1.  
  • 2. Aetiology
    • Skeletal:
      • Genetic component:
        • Prognathic maxilla
        • Retrognathic mandible
        • Combination of both
  • 3. Aetiology
    • Soft tissues:
    • Incompetent lips
      • Proclined upper incisor
    • Lower lip trap behind upper incisors
      • Proclination of upper incisors
      • Retroclination of lower incisors
    • Tongue thrust
  • 4. Aetiology
    • Habits:
    • Digit sucking habit
      • Proclination of upper incisors
      • Retroclination of lower incisors
      • AOB or in less severe forms incomplete OB
      • Cross bite
      • Incresed LFH
  • 5. Features of Class II div 1
    • Skeletal features:
      • Usually class II relation ranging from mild to sever (Large ANB angle)
      • Open bite, normal or deep (MM angle)
  • 6.  
  • 7. Features of Class II div 1
  • 8. Features of Class II div 1
    • Dental features:
      • Class II molar, canine and incisor relations
      • Proclined maxillary incisors or normally inclined
      • Increased overjet
      • Open bite, normal overbite
      • or deep bite
  • 9. Treatment modalities
    • Growth modification:
      • Head gear (High pull, low pull, medium pull)
      • Functional appliances
    • Fixed appliances (with Class II elastics)
    • Removable appliances
    • Surgery
  • 10.  
  • 11. Functional appliances
    • For growth modification in
    • a growing patients :
    1- Mild to moderate Class II div. 1 2- Proclined upper incisors 3- N o lower and upper arch crowding 4- Deep overbite 5- Average or reduced LFH.
  • 12. Effect of functional appliances
  • 13. Class II division I malocclusion
    • Removable appliances
    • Robert retractors
    • -Proclined upper incisors
    • -Spaced upper incisor
    • -Normal or reduced overbite
  • 14. Fixed appliances
    • Used for most complicated tooth movements which involve bodily tooth movement, intrusion, extrusion.
  • 15. Treatment modalities
    • Non growing patients:
      • Removable appliances:
      • e.g Robert’s retractor
      • Fixed appliances
      • Surgery
  • 16. Patient’s assessment and RX planning
    • Rx depends on:
      • Patient’s age (Grower or not)
        • Growth modification with or with out fixed appliances
      • The severity of malocclusion
      • Patients facial profile
  • 17. Retention and stability
    • For OJ reduction to be stable, anterior lip seal should be achieved
    • Lower lip contact the upper incisors
  • 18. Retention
  • 19. ORTHOGNATHIC SURGERY
  • 20.  
  • 21.  
  • 22. FIXED APPLIANCES
  • 23.  
  • 24.  
  • 25.  
  • 26. GROWTH MODIFICATION
  • 27.  
  • 28.
