  1. Treatment of CLII malocclusion

  2. CLII can be classified into • CLII div 1 • CLII div 2

  3. What we mean by CLII

  4. Some times • Molar CLI & canine CLII • Molar CLII & canine CLI • Dental CLII on skeletal CLI or CLIII due to habits ?

  5. T. Wallen

  6. Etiology of class II 1. skeletal

  7. 2. Soft tissue Over jet & over bite

  8. 3. Dental factor • In case of large teeth size so we either have

  9. In association with skeletal relationship the muscles of the lips and tongue govern the inclination and degree of vertical development of the incisors, and thus govern the incisal overjet and overbite.

  10. Treatment objectives in CLII div1 • Relief of crowding • Reduction of over bite • Reduction of over jet • Correction of CLII of buccal segment teeth

  11. Treatment of class II division 1: There are many factors that must be taken in Mind during treatment: I- Age of the patient. 2-severity of the cases. 3- Patient's cooperation.

  12. If the patient is growing start with CLII correction. • But CLII should be due to antero posterior. • But if it was due to vertical problem so further growth of the mandible will lead to posterior rotation of the mandible and in competent lips.

  13. Types of treatments • Young growing

  14. adult • Removable • fixed

  15. Sever CLII 1 • Combination of orthodontic treatment and surgery

  16. Treatment by removable appliance • CLII div 1 • Skeletal CLI or mild sk. CLII • Canine mesially angulated • Cooperative patient

  17. NOTE: always correct the overbite-before the overjet correction

  18. Treatment by removable appliance • Stage 1 Exo. Up. 4 • Adam 56 • Finger spring or BCR on 3 • Fitted labial arch • Acrylic base plate • Ant. Bite plane (flat or inclined)

  19. Stage 2 • Double Adam clasp 56 • Stoppers C clasp 3 • Ant bite plane • Robert retractor 2112

  20. Stage 3 • Retainer • Adam 6 • Hawly • Acrylic base plate

  21. Treatment by fixed appliance • Canine vertically or distally angulated • Upper incisors not proclined • 90 degree rotation • Moderate – sever CLII • Residual space • Increased over bite

  22. Surgical correction • Adult • Vertical maxillary excess • Gummy smile • Retruded mandible

  23. وجــــــهان للحق غير الله ما عبدا          وجه منير ووجـــــه يستطير هدى هـما الجواد وموسى فاعتصم بهما          فــــــفيهما الفوز دنيا والنجاة غدا هــــــما العماد لمن طاحت به عمد          هما الســـــــناد لظـهر يبتغي سندا
