10

what is a class five cleft palate

cleft of the soft and hard palate that continues through the alveolar ridge on one side, associated with cleft lip of the same side

11

what is a class six cleft palate

cleft of the soft and hard palates that continues through the alveolar ridge on both sides, free premaxilla, bilateral cleft lip

12

what is a class seven cleft palate

submucous clef in which the muscle union is imperfect across the soft palate, short palate, uvula is often bifid, groove situated at midline, closure of pharynx isnt complete

13

what are risk factors for a cleft lip or palate

multifactoral, genetic and environmental

14

what are environmental factors for a cleft lip or palate

-tobacco, alcohol consumption, teratogenic agents, inadequate diet

15

what occurs more frequently in patients with clefts than in the general population

disturbances in normal tooth development

16

what is there a higher incidence of in cleft lip and palate

missing and supernumerary teeth, missing max laterals correspond to side of mouth with cleft

17

do people with cleft lip or palate require ortho care

yes, may be required after each stage of surgical tx

18

what is there a lack of in coordinated movements in patients with a cleft lip or palate which may cause the pt to have compensatory habits

-coordinated movement of lip, tongue, cheeks, floor of mouth, throat,

19

what is dental biofilm accumulation influenced by in patients with cleft palate or lip

irregular positioned teeth, inability to keep lips closed, mouth breathing, difficulties in personal oral care

20

what is common in periodontal tissues at the cleft site in adolescents

loss of bone and clinical attachment

21

where is periodontal tissue loss greatest at

cleft sites

22

what puts patients with a cleft lip or palate at a higher risk for caries

-overprominent lower lip

26

what infections are common in cleft lip or palate

upper respiratory infections, middle ear infections

27

craniofacial anomilies of the nose and throat predispose the child with a cleft palate to

airway obstruction and breathing problems

28

do patients with a cleft lip or palate have difficulty making certain sounds

yes

29

what contributes to speech problems

-anatomic structure, airway and breathing problems and hearing difficulties

30

at 2 to 3 months of age, 10 weeks of age, weighs 10 lbs, serum hemoglobin of 10 mg/ml

32

what are purposes of early tx of a cleft lip

encourages dev of premaxilla
partial closure of a cleft

33

when is primary surgery to closure of the palate done

by age 18 months or earlier when possible

34

what are the goals for tx of closure of cleft palate

achieve normal function, (speech)
relive problems of airway and breathing
-dental esthetics and functional occlusion

35

what may secondary surgery of the cleft palate include

When is an alveolar graft placed in palatal surgery
