What we mean by CLII
Some times
Molar CLI & canine CLII
 Molar CLII & canine CLI
 Dental CLII on skeletal CLI or CLIII due to
habits ?

Etiology of class II
1. skeletal
2. Soft tissue
Over jet & over bite
3. Dental factor
• In case of large teeth size so
we either have
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.

4.
Relief of crowding
Reduction of over bite
Reduction of over jet
Correction of CLII of buccal segment teeth
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.
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.
