Oral Anatomy Canines 낱말 카드

Periodontal ligament (PDL)

What are canines heavily connected to in the mouth which makes them hard to become loose even in periodontal disease?

Canines

What are the longest teeth in the mouth?

6, 11, 22, 27

Using the universal numbering system, which teeth are the canines?

Support lips and cheeks, Cut and pierce food, Canine-protected occlusion

What are the functions of canines?

Canine protected occlusion

Occlusal relationship in which vertical overlap of maxillary and mandibular canines produce a disocclusion (separation) of all posterior teeth when mandible moves to either side

Mutually protected occlusion

In maximal intercuspal position, posterior teeth come in contact and act as stops to minimize horizontal load on anterior teeth. Anterior teeth guide all the other movements of the mandible so posterior teeth contact will not take place during lateral or protrusive movements.

Centric position

What term describes the position of teeth with maximum intercuspation?

Excentric position

What term describes the position of teeth WITHOUT maximum intercuspation?

Centric

What type of movement is shown?

Protrusive

What type of movement is shown?

Lateral (L/R)

What type of movement is shown?

Canine guidance

What term describes the eccentric position where the canines are the only teeth touching?

Group function

What term describes the eccentric position where teeth other than just canines are touching?

Canine guidance

What is considered the ideal occlusion guidance scheme?

Disocclusion (reduces horizontal load/lateral forces)

What does canine guidance cause in posterior teeth?

Distal

Is the distal or mesial contact of canines more cervical?

Is the mesial or distal CEJ of canines more curved?

Triangular (wedge shaped)

What is the shape of the proximal outline of crowns of canines?

Cervical 1/3

Where is the height of contour located facially and lingually on canines?

Lingual

Is the facet of wear on maxillary canines located on the facial or lingual surface?

Facial

Is the facet of wear on mandibular canines located on the facial or lingual surface?

Diamond

What is the shape of the incisal wear on a canine?

Rectangular (ribbon shaped)

What is the shape of the incisal wear on an incisor?

Convex

How would you describe the mesial crown contour of the maxillary canine?

Almost straight

How would you describe the mesial crown contour of the mandibular canine?

Mandibular

Does the mandibular or maxillary canine not taper from contact to CEJ?

Mandibular

Does the maxillary or mandibular canine appear bent distally?

Maxillary

Is the maxillary or mandibular canine cusp tip more pointed/sharper?

Mesial

Is the mesial or distal cusp ridge of the mandibular canine closer to horizontal?

Mandibular

Are contacts on maxillary or mandibular canines closer to the incisal edge?

Incisal 1/3

Where is the mesial contact area on mandibular canines?

Junction of incisal and middle 1/3

Where is the distal contact area on the mandibular canines?

Distal contact of maxillary canine

Which canine contact is most cervical/located in the middle third?

Junction of incisal and middle 1/3

Where is the mesial contact area of maxillary canines?

Middle 1/3

Where is the distal contact of maxillary canines located?

Distally

The root apex of maxillary canines typically curves toward which direction?

2

Canines have how many lingual fossae?

Mandibular

Are maxillary or mandibular canine crowns longer?

Maxillary

Is the lingual ridge more prominent in maxillary or mandibular canines?

Maxillary

Does the mandibular or maxillary canine have a larger cingulum?

Centered

Is the maxillary canine cingulum located mesially, distally, or centered to root axis?

Distal (distolingual twist)

Is the mandibular canine cingulum located mesially, distally, or centered to root axis?

Maxillary central incisors, mandibular lateral incisors, and mandibular canines

What 3 teeth have a distolingual twist?

Maxillary

Do mandibular or maxillary canines have more prominent marginal ridges?

Lingual

Are canine roots narrower on the facial or lingual half?

Distal

Are mesial or distal root depressions typically deeper?

Facial

(makes sense because they fit over mandibular canines)

Are the cusp tips of maxillary canines located more facial or lingual in comparison to their midroot axis?

Lingual/Centered

(makes sense because they fit under maxillary canines)

Are the cusp tips of mandibular canines located more facial or lingual in comparison to their midroot axis?

Maxillary

Is the facial height of contour more prominent on the mandibular or maxillary canine?

Maxillary

(further from CEJ)

Is the facial height of contour located more incisally on the mandibular or maxillary canine?

Maxillary (due to height of contour being located more incisally)

Does a mandibular or maxillary canine have a double convexity on the facial surface?

Distal

Both mandibular and maxillary canines have a greater root depression on the distal or mesial side?

Distal pinch

What is the term when looking incisally that the distal half of the labial surface on a maxillary canine is more concave?
