Height Of Contours

Front 1

height of contour

Back 1

how far the crown overhangs the cervical line (only on facial and lingual)

Front 2

emergence profile

Back 2

the cervial line of the height of contour is FLAT!

Front 3

height of contour on maxillary anteriors

Back 3

facial-cervial third 1/2 mm

lingual-cervial third 1/2mm

Front 4

Where are all facial height of contours?

Back 4

in cervial third

Front 5

mandibular anterior height of contour

Back 5

facial is in cervical third and is less than 1/2 mm

lingual is in cervial third and is less than 1/2 mm

Front 6

What happens if Dr. makes crown with an emergence profile that is not flat?

Back 6

inflam

Front 7

functions of proximal contacts and embrasures

Back 7

1. prevent food impaction
2. protect peridontium
3. stabilize dental arch
4. allow food to excape the occlusal surface
5. distribute forces

Front 8

what is bigger gingival or incisal embrasure?

Back 8

always gingival

Front 9

describe embrasures as you go from ant to post teeth

Back 9

as go to posterior gingival embrasure gets smaller and incisal get larger (but gingival always bigger)

Front 10

embrasure of ant teeth

Back 10

since proximal contact is in incisal third, there is a huge gingival embrasure and a v. small incisal embrasure

Front 11

describe proximal surface to proximal contact

Back 11

always flat or concave on all teeth for embrasure

Front 12

compare facial and lingual embrasures

Back 12

equal or lingual slightly larger

Front 13

where are proximal contacts in line with?

Back 13

facial cusp

Front 14

what tooth has mesial concavity?

Back 14

mesial concavity on first premolar needed bc canine is not the same shape

Front 15

descibe facial/lingual embrasures from ant to post teeth

Back 15

facial embrasures increase and lingual embrasures decrease as go posteriorly

Front 16

mandibular anterior proximal contacts

Back 16

in incisal third

Front 17

what happens if mandibular anterior teeth get too much wear

Back 17

insical embrasures disappear

Front 18

canine proximal contacts

Back 18

mesial PC in incisal third

distal PC in middle third

this causes occlusal embrasures to get larger and gingival to get smaller as come posteriorly

Front 19

what happens to embrasure as proximal contacts become more gingival (like in post teeth)

Back 19

gingival embrasures get smaller and occlusal embrasures get bigger

Front 20

posterior embrasures vs. ant embrasures

Back 20

posterior teeth have a smaller facial embrasure bc contacts are more facial and a larger occlual embrasure

Front 21

max width of arch

Back 21

1st molar

Front 22

what teeth of equal facial and lingual embrasures?

Back 22

mandibular incisors

Front 23

% of max lateral incisor that should be seen in smile

Back 23

70%

Front 24

how much shorter should max lateral incisor be that central?

Back 24

1 mm

Front 25

what gives smile youthful appearance

Back 25

incisal embrasure

Front 26

why do caries spread rapidly in children?

Back 26

thinner enamel and dentin and their dentin is less dense

Front 27

describe primary dentition

Back 27

thinner enamel and dentin

dentin less dense so whiter teeth

larger pulps and taller pulp horns

longer roots in relation to crown size

roots v. flared

Front 28

why do primary teeth have flared roots?

Back 28

bc perm tooth bud sits in that space

Front 29

primary tooth crown

Back 29

more bulbous appearance of crown due to small occlusal table and constricted CEJ. HUGE HEIGHT OF CONTOUR

Front 30

primary first molars

Back 30

have distinctive mesial facial bulge. looks way different

Front 31

what do primary second molars look like?

Back 31

clones of permanet first molars

Front 32

function of primary teeth

Back 32

space maintainers so when first pre molars erupt they hold arch so man. molars can come in
