Cleft/Dentition Flashcards
1
Q
Genetic Abnormality
(something
wrong with
the genes)
A
- Autosomal Dominant
inheritance in some
syndromes. - Recessive genetic
inheritance in some
syndromes. - X linked
inheritance in some
syndromes. Chromosomal
abnormalities
2
Q
Environmental Factors (outside of uterus)
A
- Fetal alcohol syndrome
- Illegal drug use
- Side effects of some
prescription drugs - Rubella
3
Q
Mechanical Factors (things that
happen inside the uterus)
A
- Intrauterine crowding
- Twinning
- Uterine Tumor
- Amniotic Ruptures
4
Q
Class I Malocclusion
A
- An overlap of upper teeth
over the lower teeth. - Due to prolonged
bottle use or thumb
sucking in childhood.
Doesn’t affect your bite
that much and can be fixed
with minor malocclusion
treatment.
5
Q
Class II Malocclusion
A
- Overbite
- The upper teeth stick out
over lower teeth. - Severe enough to affect
your bite significantly. It
needs early orthodontic
intervention.
6
Q
Class III Malocclusion
A
Type of underbite where
the lower teeth stick out
over the upper teeth.
7
Q
Velopharyngeal Insufficiency
(VPI)
A
- abnormal structure
- Structural defects resulting in
insufficient tissue to accomplish closure. Needs surgery - Cleft palate, Down syndrome, large tonsils, can develop after surgery to remove the adenoids, glands in the roof of the mouth that sometimes have to be removed if they grow too large or brain injury caused by a stroke
8
Q
Velopharyngeal Incompetence
A
- abnormal movement
- inadequate movement
of the velopharyngeal
structures is usually due to a
neurological disorder or
injury (as in cerebral palsy
or traumatic brain injury)
9
Q
Nasoalveolar Molding (NAM)
A
- 1 week - 3 months
- Gradually brings the lip and
palate together, improving
nasal symmetry
10
Q
Cleft Lip Repair
A
- 3 to 6 months
- Repairs the separation of
the lip, realigns lip muscles,
and often includes primary
nasal repair.
- First surgical step
11
Q
Cleft Palate Repair (Palatoplasty)
A
- 9 to 18 months
- Repairs the roof of the mouth, allowing for normal eating, speaking, and swallowing. It
involves closing the palate in layers and realigning the palatal muscles
12
Q
Alveolar Bone Graft and Fistula
Repair
A
- 6 to 9 years
- Creates a complete dental arch and closes any fistulas (openings) between the gum and nose.
13
Q
Palatal Expansion
A
- 5 to 7 years
- Prepares the child for subsequent bone grafting by widening the palate.
14
Q
Complete Cleft Lip
A
Extends from the lip to the nose.
15
Q
Incomplete Cleft Lip
A
Does not reach the nose.
