      - Lingual eruption of lateral
      - Ectopic eruption
      - Tooth size arch length discrepancy
      - Canines erupting mesially
      - Premature loss of deciduous
    - - Lesser retention period with more stable results
      - Reduces the cost of treatment
      - Better oral hygiene
      - Reduces the severity of malocclusion
      - reduces the period of future appliance therapy
      - No loss of alveolar bone
      - Physiologic tooth movement
    - - Class I malocclusion
      - Minimal overjet and overbite
      - Straight facial pattern
      - true hereditary tooth size arch length discrepancy
    - - Lingual tipping of mandibular incisors
      - Patient co-operation is required
      - canine can erupt ahead
      - appliance therapy
      - mesial drifting and space loss
      - Ditching between the canine and second premolar can occur
      - Longer duration
      - tongue thrust
      - not be tolerated by children
    - - tooth size arch length discrepancy
