Orthodontics — Key differences for NEET MDS
SNA = 82 degrees maxilla position relative to cranial base. SNB = 80 degrees mandible position relative to cranial base. ANB = 2 degrees skeletal relationship Class I. ANB greater than 4 = Class II skeletal. ANB less than 0 = Class III skeletal. Wits appraisal when ANB unreliable. Tweed triangle = FMA FMIA IMPA. Steiner analysis = SNA SNB ANB.
