Quiz: Alveolar Bone Grafting in Cleft Lip and Palate

What is the main objective of alveolar bone grafting (ABG) in cleft lip and palate patients?

• To replace missing teeth

• To close the lip deformity

• To restore alveolar bone continuity and support tooth eruption

• To correct nasal asymmetry

Which of the following is considered the most optimal timing for ABG according to the review?

• Before age 2

• Between ages 2-5

• Between ages 6-12, before canine eruption

• After age 16

What is a potential negative outcome of primary alveolar bone grafting (before age 2)?

• Canine impaction

• Speech delay

• Disturbance in maxillary growth

• Nasal collapse

What is a major benefit of performing ABG during the conventional secondary phase (ages 6-12)?

• Lower cost

• Avoidance of orthodontic treatment

• Improved spontaneous canine eruption

• Less need for follow-up

What is a common reason for tertiary alveolar bone grafting?

• To replace baby teeth

• As part of cleft palate surgery

• To treat failed or missed earlier grafts

• For cosmetic enhancement

What age range corresponds to early secondary alveolar bone grafting?

• Birth to 2 years

• 2 to 5 years

• 6 to 12 years

• 13 years and older

Why is late secondary grafting (after age 12) generally less preferred?

• It is too expensive

• It does not allow for eruption of the permanent canine

• It requires general anesthesia

• It results in overgrowth of the maxilla

Which of the following is NOT typically evaluated when assessing ABG outcomes?

• Bone fill

• Hearing thresholds

• Tooth eruption

• Fistula closure

What type of bone is commonly used for alveolar bone grafting?

• Rib bone

• Mandibular bone

• Iliac crest bone

• Skull bone

Which statement best summarizes the study's conclusion?

• Early intervention always produces better results

• Delayed bone grafting is more cost-effective

• Conventional secondary ABG provides the best balance of timing and outcomes

• All ABG techniques produce equal results
