What is the problem?
In  Angle  classification emphasize the  ( distal  ) positioning of the  mandible to the  maxilla In  Class II Malocclusion  , but of course many Class II cases are seen in  which the maxilla Is  prognathic  --  quite a different  craniofacial  morphology  but    producing  a similar molar relationship. And hence the same classification. The mesial groove of the mandibular first permanent molar articulates posteriroly to the mesiobuccal cusp of the maxillary first permanent molar. Although the  word distal is commonly used in this manner  to  describe Ciass II ,  it is  of course  wrong  , Distal reffers solely  to teeth  surfaces or directions and  the  Class II malocclusion  involves  primarily the  bony  skeleton .If  one  wishes  to describe the  relationship of the  mandible to the  cranial base , for  example , words Such  as posterior or dorsal are more correct .
Divisions   are as follows :
1)  Division 1, 2) Division 2 and 3) Subdivisions.
How is the problem Typified?
Treatment  planning are as follows :
1) Treatment planning in the primary dentition   .
2) Treatment planning in the early mixed dentition.
3) Treatment planning in the permanent dentition.
4) Treatment planning in the adult patients.
Treatments consiste of  :
1 ) Growth modification
2 ) Camouflage
3 ) Surgery
