In a child with a cleft of the alveolus/palate, secondary alveolar bone grafting is typically performed at about:

  1. 1–2 years of age
  2. 8–11 years (mixed dentition, before canine eruption)
  3. 16 years of age
  4. After 18 years of age
Show answer and explanation

Correct answer: B. 8–11 years (mixed dentition, before canine eruption)

  • C. Generally later than ideal for the canine.
  • D. Past the optimal window for canine support.
