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.

Etch and rinse still best for enamel bonding. Smear layer removed in total etch. Smear layer modified in self-etch. Hybrid layer = resin infiltrated dentin.
