Card 1
Question: In cleft patients during primary dentition, what orthodontic treatments are typically indicated at this stage?
Answer: Limited to correction of certain posterior crossbites and mild-to-moderate anterior crossbites.
Card 2
Question: Why are posterior crossbites in cleft patients often of skeletal origin?
Answer: Because maxillary segments are usually collapsed after cleft palate surgery, especially in the canine region.
Card 3
Question: How does early collapse of maxillary segments affect eruption of primary canines in cleft patients?
Answer: The maxillary cleft‑side primary canine often erupts medial to the lower one, causing minor palatal displacement of the maxillary primary canine and l
Card 4
Question: Why do cleft patients in the primary dentition rarely have occlusal or functional shifts?
Answer: Because the altered arch form and canine eruption pattern typically establish a stable early relationship that does not produce shifts; patients with
Card 5
Question: What are the considerations for performing transverse expansion in the primary dentition for cleft patients?
Answer: Expansion can be done but must be retained until alveolar bone grafting; therefore the authors prefer to delay transverse expansion in primary dentiti
Card 6
Question: How can mild-to-moderate anterior crossbite be managed in primary and transitional dentition for cleft patients?
Answer: With elastic protraction forces delivered through a facial mask.
Card 7
Question: When is surgical management preferred for anterior crossbite in cleft patients?
Answer: If the crossbite is related to moderate-to-severe skeletal maxillary hypoplasia, surgical approaches are preferred.
Card 8
Question: What alternative to conventional face mask therapy has been used for early maxillary advancement?
Answer: Distraction osteogenesis for severe cases, and an intraoral spring-and-screw technique (Liou and Tsai) applying constant anterior pressure plus screw-
Card 9
Question: What is the transitional dentition stage relevant to cleft orthopedics?
Answer: The stage when, for alveolar-involving clefts, the next surgical procedure (secondary alveolar bone grafting) is planned after lip and secondary palat
Card 10
Question: What pre-surgical orthodontic approach is used to improve surgical access in transitional dentition for cleft patients?
Answer: Premaxillary orthopedics with a self-retaining intraoral appliance retained with denture adhesive and an elastic strap for premaxillary retraction to
