6. Why are implants not generally performed on a 12-year-old patient with congenitally missing lateral incisors?

Waiting for the crowns is too much of an esthetic issue with most children that age.

The gingival tissue will recede as the child gets older.

The patient would likely not be able to tolerate the surgical procedure.

9. Your patient is 8 years old. Teeth #8 and #9 have approximately 50% of their crowns erupted. One month ago, the patient fell from a skateboard and hit teeth #8 and #9 on the sidewalk.

Calcium hydroxide pulpotomy

Formocresol apexification technique

Calcium hydroxide apexification technique
