development of occlusion in the primary and transitional dentition

Question 1

shape of the maxillary arch in children

Answer 1

Ovoid in shape

Question 2

shape of the mandibular arch in children

Answer 2

V shape

Question 3

do teeth push jaws appart

Answer 3

no, growth of mandibule is then filled with teeth

Question 4

is space between baby teeth normal

Answer 4

No

Question 5

how large is the combined mesiodistal width of the permanent incisors

Answer 5

Larger than the width of the primary inciors

Question 6

how does the maxillary arch accomidate new teeth

Answer 6

Utilization of any interdental spaces betwen lateral and centrals
Utilization of max primate space betwen lateral and canine
Labial eruption of the incisors increasing arch length and circumference
Increase in width of the ental arch acros the canines

Question 7

how does the mandible acccomidate new teeth

Answer 7

Utilization of any developmental spaces between incirors

Increase in intercanine width

Question 8

how do we classify posterior occlusal relationship

Answer 8

by the relationship of the distal terminal planes of the upper and lower second primary molars

Question 9

Flush terminal plane

Answer 9

Distal surfaces of opposing primary second molars are the smae verticle plane

Question 10

mesial step terminal plane

Answer 10

mandibular is mesial to the terminal place of the maxillary primary second molar

Question 11

what does mesial step correspond to

Answer 11

Angle Class I

Question 12

what is the normal relationship of the permanent dentision

Answer 12

MEsial step

Question 13

distal step terminal plane

Answer 13

MAndibular is distal to maxiary

Question 14

Whis does the distal step correspond to

Answer 14

Angle class II

Question 15

Odds of Flush terminal plane, MEsial and Distal

Answer 15

FLush 37%
Mesial 49%
Distal14%

Question 16

end to end

Answer 16

Long axes of the upper and lower cnaine are in the same anteroposterior plane

Question 17

Class I

Answer 17

Cusp tip of upper occludes the embrasure between the lower canine and lower first molar

Question 18

Class II

Answer 18

Cusp tip of upper canine occludes mesial and lower canine in the embrasure betwen the lower canine and lateral incisors

Question 19

Class III

Answer 19

Cups tip of upper canine occcludes distal to the embrasure between the mandibular first primary molar and canine

Question 20

mesial terminal plane leads to what

Answer 20

Class I molar permanent molars

Question 21

Flush terminal plane leads to

Answer 21

End to end permanent molars

Question 22

Distal terminal plane leads to

Answer 22

class II molar permanent molars

Question 23

the difference in the combined md width of the primary cnanin, first molar, second molar, and the succedaneous permanenent canine, first premolar, and second premolar

Answer 23

Leeway space

Question 24

width of primary teeth vs three permanent teeth

Answer 24

primary teeth wider

Question 25

what closes the primate spaces

Answer 25

first permanent molars slide forward, early mesial shift

Question 26

what shifts more mesials, amnibles of maxillary

Answer 26

mandible

Question 27

what does the late mesial shift allow

Answer 27

Allows a flush terminal plane in the mixed dentition to transition to a class II relationship

Question 28

what is the late mesial shift

Answer 28

molars shift mesially in the mandible

Question 29

appart from shift, what else determines molar position

Answer 29

forward Growth of the mandible in relation to the maxilla
