Orthodontics — Key differences for NEET MDS
NiTi = most flexible lowest stiffness for alignment phase. Stainless steel = highest stiffness for finishing detailing. TMA = beta titanium = intermediate properties. Ideal arch wire sequence: NiTi then TMA then SS. MBT prescription most common. Roth prescription = 0 degree torque. Pre-adjusted edgewise = straight wire.

Headgear = extraoral anchorage cervical pull or high pull. Critical anchorage = ALL space needed for crowding. Maximum anchorage = most space for retraction. Moderate anchorage = reciprocal movement acceptable.
