Answer 1

factors and forces that determine the tooth position

Question 2

tooth position based on
1
2
3

Answer 2

1. muscles (cheeks, lips, and tongue)
2. genetic (size and shape of arch and teeth-> available sace)
3. habits

Question 3

the relationship of the teeth to each other within the dental arch

Answer 3

intra-arch tooth alighment

Question 4

plane that curves to fit the occlusal surfaces and incisal edges of all the teeth:

is this flat?

Answer 4

plane of occlusion
no NOT flat

Question 5

concave:
convex:

Answer 5

concave: mand
convex: max

Question 6

determined by the long axis of the tooth (crown and root)

Answer 6

angulation of the teeth

Question 7

angulation of mand teeth sagittal plane explain:

Answer 7

anterior teeth= labially inclined 20 degrees
premolars= mesially inclined 6 degrees
molars= mesially inclined (10-15 degrees)

Question 8

angulation of max teeth sagittal plane explain:

Answer 8

anterior teeth=labially inclined (CI most at 28 degrees)
premolars= mesially inclined 9 degrees
molars= mesially inclined 12 degrees

Question 9

angulation of mand teeth frontal plane explain:

Answer 9

anterior teeth= vertical inclined 0
premolars= 1st= labial inclined 9
2nd= lingual inclined 9
molars= lingual inclined 20

Question 10

angulation of max teeth frontal plane explain:

Answer 10

anterior= incisors= distal
canines= mesial

premolars= slight buccal

molars= buccal

Question 11

antero-posterior curvature of occlusal plane

Answer 11

curve of spee

Question 12

medio-lateral curve of occlusal plane

Answer 12

curve of wilson

Question 13

when posterior teeth occlude, they are loaded

Answer 13

axially

Question 14

what are designed to take heavy lodas, support the occlusal vertical dimension

Answer 14

posterior teeth

Question 15

when anterior teeth occlude, they ________ through their long axis

Answer 15

are NOT loaded through they long axis (guiding excursive movements)

Question 16

what are not designed for loading

Answer 16

anterior teeth

Question 17

the occlusal table is the area defined by the _____and the mesial and distal ____

Answer 17

cusp tips and the M/D cusp ridges/arms

Question 18

occlusal table is ____% of the buccolungual width of the tooth. facilitates axial loading

Answer 18

50-60

Question 19

(occlusal table) inclines inside the buccal and lingual cusp ridges

Answer 19

inner inclines

Question 20

(occlusal table) inclines outside the buccal and lingual cusp ridges

Answer 20

outer inclines

Question 21

the relationship of the teeth in one arch to those in the other arch

Answer 21

inter-arch tooth alighment

Question 22

supporting/centric/functional/stamp cusps:

Answer 22

L cusps of max and B cusps of mand

Question 23

guiding/non-centric/balancing/shearing cusps

Answer 23

B cusps of max and L cusps of mand

Question 24

imaginary line drawn thru buccal cusp tups of mand teeth

Answer 24

BO line

Question 25

imaginary line defined by joining the lingual cusp tips of max teeth

Answer 25

LO line

Question 26

imaginary line that follows the central grooves and fossa of all posterior teeth

Answer 26

CF line central fossa line

both BO of mand and LO of max occludes CF line

Question 27

the opposite of the ideal inter-arch relationship
(BO of max occludes with CF and LO of mand occludes with CF instead of other way around)

Answer 27

crossbite

Question 28

great vertical overlap, the mandibular teeth contact the gingival third of the max anterior teeth (deep bite)

Answer 28

division 1 class II anterior teeth

Question 29

max incisors are lingually inclined, laterals overlap the centrals labially

Answer 29

division II class II anterior teeth

Question 30

class III anterior tooth relationship:
1
2

Answer 30

1. end to end relationship
2. mandibular anterior teeth are so far forward overlapping max anterior teeth
