Canines Flashcards
other names for canines
cuspids or eye teeth
general characteristics of canines
single pointed cusp
the “cornerstone” of the arch
important teeth for esthetic and functional aspect
canines #
6, 11, 27, 22
what is different about roots of canine
have the longest and thickest roots faciolingually of all teeth
very stable
canine eminence=
and what does it do
prominent ridge of bone on the labial aspect
-helps support facial musculature
Function of mandibular canines
- guiding teeth: they slide along lingual surface of maxillary and guides the mandible
- long roots: good for anchoring
of maxillary canines
6 and 11
when do maxillary canines erupt
11-12 years
how many developmental lobes do maxillary canines have
4 lobes
3 are labial, 1 develops into cingulum
what are the three labial lobes of maxillary canines
mesial, middle and distal
how to the size of maxillary and mandible canines compare?
maxillary canine is larger than the mandible canine
cusp in maxillary canines
is made up of 4 ridges
mesial, distal, facial and lingual cusp ridge
maxillary canine facial view
- the outline is 5 sided figure
- mesial and distal sides are above the contact, cervical line, and mesial and distal cusp arm
- cusp tip in line with the center
- incisal margin is 1/3 of size
- mesial cusp ridge is shorter and less sloped than distal cusp ridge
- distal outlive is concave from contact to cervical line
- has a prominent facial ridge
- mesial to facial: convex
- distal to facial: slight concave
what is the geometric form of maxillary canines
trapezoidal, not 5 sided because cusp tip is not included
what is the different between maxillary canines mesial and distal cusp ridges
mesial: shorter, less sloped
distal: distoincisal angle is greater
contacts on facial view of maxillary canines
mesial contact: junction of middle and incisal 1/3
distal contact: in the middle 1/3
maxillary canines root
- conical
- long and narrow MD
- apex curves apically
- convex on labial aspect
- looks more narrow
- can see developmental depressions on mesial and distal
- looks broad labioligually
maxillary canines lingual
- crown and root are narrower
- CEJ has greater curvature here
- distinct mesial and distal marginal ridges
- prominent convex cingulum
- mesiolingual and distolingual fossa
- lingual ridge blends into the incisal portion of cingulum from cusp tip
what teeth can we see mesial and distal developmental depressions on the root?
maxillary canines and mandibular incisors
maxillary canines mesial view
outline: triangular
- very wide faciolingually in cervical third
- cusp tip is labial to bisecting line
- labial: slightly convex,
- lingual: convex in cingulum, concave in incisal portion
- height of contours for both is in the cervical third
maxillary canines distal view
very similar to mesial BUT
- has concavity between the contact and cervical line
- looks bigger on distal
- developmental depression is more pronounced on root
maxillary canines incisal view
- labiolingual dimension > mesiodistal dimension
- contacts are centered
- cusp tip is labial to the center of the crown
- mesial half: convex
- distal half: concave
- can see depression on labial from incisal
- prominent labial ridge, can see distolingual and mesiolingual fossae
maxillary canines distinct characteristics
- the longest tooth in the arch
- broadest FL single rooted tooth
maxillary canine pulp
- 1 pulp horn
- mesial and distal root concavities: distal more pronounced
- round in shape in apical thirds
- oval in cervical and middle thirds
