Ortho vs Conservative — Key differences for NEET MDS
Most common relapse = lower anterior crowding. Bonded retainer = permanent fixed retainer. Hawley retainer = removable with labial bow. Circumferential supracrestal fiberotomy prevents rotational relapse. Vacuum formed retainer = Essix = clear overlay. Relapse causes: late mandibular growth, soft tissue pressure, periodontal fiber recoil.

Lower incisors often have 2 canals. Maxillary premolar = 2 canals common. C-shaped canal = mandibular second molar. Isthmus between canals.
