final canines Flashcards
facial shape?
pentagon
mesial or distal cusp ridge is shorter?
mesial cusp ridges shorter
vertical labial ridges are prominent or not? more so on max or mand?
prominent, common on Max
crowns are wider in what dimension
FL than MD (same as mand incisors)
crown outlines are more ____ on the distal and ____ on mesial
convex on distal and flat on mesial
distal contacts and mesial contacts?
distal= more cervical mesial= incisal third (or junction of incisal and middle)
roots are wider ____ than _____?
wider FL than MD
If roots are bent they bend in apical third to distal, BUT what tooth root is more likely to be straight?
mandibular canine
canine roots are longer or shorter than crown?
considerably longer
cervical lines on facial and lingual curve towards?
the apex
canines are what shape from proximal veiw?
triangular (like incisors)
facial and lingual crests of curvature are?
in the cervical third
what is the shape of lingual outlines? marginal ridges?
S-shaped with concave lingual fossa and convex cingulum; marginal ridges are more vertical than horizontal
incisal edges run from the ____ to the _____ contact areas?
mesial to distal
are facial or lingual outlines more broadly rounded on canines? why?
facial outlines more broadly rounded than lingual due to lingual convergence
both Max and Mand overal dimensions?
longer incisocercially then MD; BUT the MD dimensions are narrower on mand canines
difference between Max and mand mesial crown outline?
Max have a mesial crown outline convex (nearly flat) verses mandibular; Mand mesial outline is less convex and aligned with outline of root
difference between Max and mand distal crown outlines?
distal outline of max canine is more concave in the cervical third
Max or mand has a more pointed/acute angle formed by the cusp ridges?
Max= pointed= 105= sharper cusp mand= broad= 120= less pointy
when the mandibular canine is held with the long axis vertical, the mesial cusp ridge is?
horizontal
lingual ridges that separate the mesial and distal fossae are more prominent on Max or mand?
Max
cingula location on canine?
Max= large and centered mand= slightly distal
on mandibular canines, the distal cusp ridge bends?
distolingually
incisal ridges on maxillary canines are straighter?
MD
what half of the max canine is compressed in incisal view?
distal half of crown
cusp tip of max is labial or lingual to root axis line?
proximal view
max canine is most likely ON or labial to root axis
*mand cusp tip is lingual or on root axis line
