Rapid Maxillary Expansion

Rapid Maxillary Expansion

Write short note on role of expansion in orthodontics.
Answer. Expansion in orthodontics is of two types, i.e. rapid maxillary expansion and slow maxillary expansion.

“Understanding the role of rapid maxillary expansion in orthodontics: Q&A explained”

• Rapid maxillary expansion leads to skeletal arch expansion.
• Rapid maxillary expansion is indicated in the following cases in orthodontics:
  • In class 3 malocclusion
  • In posterior skeletal crossbite either unilateral or bilateral.
  • In some class 2 cases in which maxilla is narrow.
  • In clef palate cases with destroyed maxillary arch.
  • For gaining space in anterior crossbite.
  • In high angle cases.

“Importance of studying rapid maxillary expansion for better orthodontic outcomes: Questions explained”

• Slow maxillary expansion leads to dentoalveolar expansion.
• Slow maxillary expansion is in the following cases in orthodontics:
  • Relieve crowding in less space discrepancy.
  • In posterior dental crossbite in a single or two teeth.
  • In clef palate patients with destroyed maxilla.
  • In constricted maxillary arch.
