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.

Type III = liner base. Biocompatible = no pulp irritation. Sandwich technique = GIC base with composite overlay. Metal-modified GIC = cermet.
