ANB angle of 2 degree | MDS entrance preaparations

The ANB angle of 2 degree usually indicates:

A. A favorable relationship of maxillary alveolar base to Mandibular alveolar base
B. A favorable relationship of mandible to cranium.
C. Poor cranial growth
D. Upright incisors

         Ans. (A) It is normal angle and represents relationship of alveolar process of mandible

                  A.N.B angle

        This angle is formed by the intersection of lines joining nasion to point A and nasion to point B

     • It denotes the relative position of the maxilla and mandible to each other                         

     • The mean value is 2°.

   • An increase in this angle is indicative of a class II skeletal tendency while an angle that is less than normal or a negative angle is suggestive of a skeletal class III relationship.
