Q

If primary MAX 1M is lost…what will happen:

Before eruption of max permanent 1M

During eruption of max permanent 1M

After eruption of max permanent 1M

A

Little/no loss of space, no maintainer

Eruption will move primary 2M mesially and lose arch space, need maintainer

Intercuspation of opposing teeth prevent movement, no space maintainer

If primary MAX 2M is lost…what will happen:

Before eruption of max permanent 1M

During eruption of max permanent 1M

After eruption of max permanent 1M

A

Little/no loss of space, no maintainer

Loss of arch space, need maintainer

Space loss likely b/c no primary 2M to buttress, NEED space maintainer despite intercuspation

Q

If primary MAND 1M is lost…what will happen:

Before eruption of mand permanent 1M

During eruption of mand permanent 1M

After eruption of mand permanent 1M

A

No space loss, no maintainer

Q

Fixed anterior bridge indicated for pt…

A
22
Q

Removable appliance for pt…

A

> = 3yo

23
Q

Pedi partial for what teeth?

A

anterior and posterior

24
Q

Advantages of fixed maintainers (3)

A

minimal cooperation, difficult to break
Cannot be lost
less of food trap than removable

25
Q

Disadvantages of fixed maintainers(3)

A

Decalcification of abutment teeth can occur bc bands
Longer chair time
loss of abutment teeth possible before permantent erupt

26
Q

Advantages of removable maintainers (4)

A

Functional - cant be accidentally activated
Prevents supraerution
Esthetic
Modified easily

27
Q

Disadvantages of remo maintainers (3)

A

Maximum cooperation needed, can be lost/broken
Food trap
May lose stability

28
Q

Easier to regain space in maxilla or mandible?

A

Max

29
Q

4 types of space regainers

A

Brass Ligature wire/Halterman
Lip Bumper
Pendulum Appliance
Extra-oral appliance

30
Q

Ectopic eruption most common in which tooth?

A

permanent max 1M, 2-6% population

31
Q

Risk factors/etiology for ectopic eruption (2)

A

small maxilla, large molars

32
Q

Ectopic eruption resolves spontaneously/frees self how often? Called what?

A

66%, reversible

33
Q

Irreversible form of ectopic eruption results in what?

A

premature exfoliation of primary 2M

34
Q

Treatment of ectopic exfoliation?

A

elastic separators
brass wire - space regaining
halterman appliance

35
Q

Infantile vs Mature swallow differences?

A

infantile - muscles of facial expression, lips contracted, tongue extends, no molar contact

mature - tongue touches roof of mouth, muscles mastication involved

36
Q

Infantile aka? mature?

A

infantile - visceral

mature - somatic

37
Q

Thumb sucking impact on..
alveolar process
incisors
bite

A

alveolar process - distortion anteriosuperiorly
incisors - labial inclination of max, lingual inclination of mand incisors

bite - increased overjet, decreased overbite, anterior open bite

38
Q

Treatments of tongue thrust?

A
  1. crib

2. myofunctional therapy

39
Q

3 functions of palatal crib

A
  1. prevents thumb from entering normal position
  2. restrains thumb from displacing incisors
  3. restrains tongue
40
Q

Bluegrass is what? what 2 fncs

A

Plastic roller

  1. prevents thumbsuckgin
  2. eliminates tongue thrust
41
Q

Treatment for thumb sucking/tongue thrust may result in temporary adverse effects (2)

A
  1. period of upset after insertion

2. difficulty speech/eating

42
Q

Best chance of success for tongue thrust/thumb sucking for…(2)

A

younger patients

remains in treatment for 6-10 months

43
Q 
Mouth breathing structure changes (5)
lip
facial height
alar base
max arch
mandible
A 
lip incompetence
long lower facial height
alar base narrow
narrow V-shaped max arch
high mandibular plane angles
44
Q

two types of anterior crossbite

A

dental

skeletal

45
Q

Dental anterior crossbite caused by?
tx?

skeletal?
tx?

A

dental - local factors
tx: quad-helix, hawley, multi-loop/trapeze, delta loop

skeletal - genetic
tx: facemask

46
Q

posterior crossbites self correct? treatment of primary dentition crossbite what effect on permanent?

A

no, positive effect

47
Q

Posterior crossbite origin?

A

genetic

48
Q

Orthopedic expansion age consideration

A

more successful before suture closure

female 14 male 15

49
Q

Hyrax appliance a type of
opens what suture
how much force generated
how much opening per turn

A

orthopedic appliance
midpalatal
15-20lbs
0.25mm

50
Q 
Slow vs rapid expansion
force
expansion amt
tissue damage
age considerations
diastema?
A 
rapid:
force: 10-20lbs
expansion: 0.5-1mm/day
tissue damage: hemorrhage and fluid in sutural space
age: not for preschool children
big diastema
slow:
force: 2-4lbs
exp: 1mm/week
damage: minimal, more adaptation
no diastema
51
Q

Need for over-treatment bc?

A

20% relapse
