Orthodontics — Key differences for NEET MDS
Class I = normal molar relationship crowding anterior. Class II Division 1 = proclined upper incisors overjet increased. Class II Division 2 = retroclined upper incisors deep bite. Class III = mesial lower molar anterior crossbite prognathism. Key is UPPER FIRST MOLAR to LOWER FIRST MOLAR relationship. Dewey-Anderson modification of Class I.

Ideal arch wire sequence: NiTi then TMA then SS. MBT prescription most common. Roth prescription = 0 degree torque. Pre-adjusted edgewise = straight wire.
