Orthodontics — Key differences for NEET MDS
Careys analysis = mixed dentition space analysis. Moyers probability table = prediction of unerupted teeth. Bolton analysis = tooth size discrepancy. Extraction patterns: 4 first premolars most common. Serial extraction for severe crowding early treatment. Leeway space = difference E and 5. Nance analysis = arch perimeter.
📖 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 Space Analysis & Extraction and Retention & Relapse in Orthodontics is crucial for scoring well. Questions may test diagnostic features, treatment approaches, or characteristic findings.
