Orthodontics — Key differences for NEET MDS
Nance holding arch = maxillary anchorage. Lingual arch = mandibular anchorage. TADs mini screws = absolute anchorage = skeletal anchorage. 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.
📖 Read full notes →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.

Understanding the key differences between Anchorage Types and Retention & Relapse in Orthodontics is crucial for scoring well. Questions may test diagnostic features, treatment approaches, or characteristic findings.
