28
Q

Because the upper incisors erupt to the labial/facial of the primary teeth, how does this effect the arch size?

A

arch size expands

29
Q

Because the lower incisors erupt to the lingual of the primary teeth, how does this effect the arch size?

A

arch size decreases

30
Q

The roots of primary teeth are:

A

symmetrical

31
Q

only ____ primary teeth are smaller compared to permanent teeth

A

anterior (incisors & canines)

32
Q

Since permanent teeth are typically larger than the anterior primary teeth, what issue do we run into?

A

incisor liability

33
Q

Some or all primary ____ teeth are larger than their successor

A

posterior

34
Q

The upper second premolar replaces the:

A

Upper second primary molar

35
Q

The upper second permanent premolar replaces the upper second primary molar, what size of teeth are involved?

A

Upper second permanent premolar= 7.0 mm

Upper second primary molar= 8.2mm

(1.2 mm difference)

36
Q

The lower second permanent premolar replaces the lower second primary molar, what size of teeth are involved?

A

lower second premolar= 7.0 mm

lower second primary molar= 9.9mm

(2.9 mm x2 =6)

37
Q

The difference in sizes between the posterior primary teeth and posterior permanent is an important aspect in:

A

interceptive orthodontics

38
Q

An imaginary surface that passes through the occlusion of the teeth:

A

occlusal plane (OP)

39
Q

The secret to orthodontic treatment is to create:

A

a desirable occlusal plane

40
Q

The surface of the occlusal plane is curved so it is strictly speaking, not a plane but is approximated by one straight line ____ view based on specific reference points within the dental arches.

A

lateral view

41
Q

Unlike the primary teeth, the permanent teeth are not ____ to the occlusal plane

A

90 degrees

42
Q

Forms in the PERMANENT dentition in response to the fact that our mandible goes through excursions:

A

curve of spee

43
Q

In the primary dentition, the curve of spee is:

A

flat

44
Q

If there is is a curve of spee in the primary dentition that is not flat this signifies:

A

severe malocclusion

45
Q

response of dentoalveolar process to the skeletal dysplasia or to function disturbance (are not fully expressed)

A

dentoalveolar compensations

46
Q

If you have a discrepancy between the maxilla and mandible in deciduous dentition, the level of the occlusal plane will be effected and the _____ will compensate

A

dentoalveolar process

47
Q

Describe the dentoalveolar compensations in the primary dentition:

A

very minimal because normally the maximal and mandible are in a low amount of growth

48
Q

If a malocclusion is diagnosed in the primary dentition, it will most probably:

A

get worse during growth

49
Q

Occlusal relations in the deciduous dentition:

  1. upper and lower incisors are ___
  2. minimal __ & __
  3. upper canine tip is positioned in the ____ between the lower canine and first primary molar
A
  1. vertical
  2. overbite & overjet
  3. embrasure
50
Q

As far as occlusal relations in the deciduous dentition, the upper canine tip is positioned in the ___ between the lower canine and the first primary molar

A

embrasure

51
Q

If your upper canine is well tucked into the embrasure between the lower canine and first primary molar this describes ___ occlusion

A

class I

52
Q

How do you measure overbite?

A

the amount of coverage of the lower incisor form the upper incisor

53
Q

Usually in the primary dentition, overbite = ____ percent

A

10-30%

54
Q

the amount of distance between the lower incisor and upper incisor from the lingual surface of the upper to the labial surface of the lower

A

overjet

55
Q

Typical overjet measurement in primary dentition is:

A

1-2 mm

56
Q

What provides the most interdigitation in the primary dentition?

A

canine

57
Q

In the primary dentition, if the canine is forward (anterior) in occlusal relations this will result in:

What if the canine is posterior?

A

class II

class III

58
Q

pushing of incisors with tongue may result in:

A

anterior open bite

59
Q

describe a reverse overjet malocclusion:

A

when the maxillary incisors are behind the mandibular incisors

60
Q

In deciduous dentition, normal occlusal changes are due to ____, NOT from ____.

A

skeletal growth; dental changes

61
Q
  • altering functional environment
  • altering neuromuscular pattern
  • introducing habits such as thumb sucking

these can alter:

A

alter skeleton and occlusion resulting in malocclusion

62
Q

Functional disturbances or thumb sucking habits are involved in the:

A

etiology of malocclsuions

63
Q

in deciduous dentition, unfavorable ___ leads to malocclusion even in young patients

A

skeletal patterns

64
Q

___ dental eruption may lead to malocclusion

A

ectopic dental eruption

65
Q

ectopic dental eruption is pretty much reserved to:

A

permanent dentition

66
Q

When the upper and/or lower jaws (maxilla, mandible) are not aligned properly in relation to the cranial base:

A

skeletal malocclusions

67
Q

What influences skeletal malocclusion (which is when the upper and or lower jaws are not aligned properly in relation to the skeletal base)?

A

STRONG genetic influence

but some claim that function can create significant skeletal malocclusion also

68
Q

Missing primary teeth is:

A

very rare
