Incisors Flashcards
Mandibular distal malocclusion
Retrognathic profile (22%)
Mandibular mesial malocclusion
Prognathic profile (6%)
Max CI: IC vs MD dimension
Wider IC than MD
What teeth have incisal edges more likely lingual to midroot axis?
Mandibular incisors
Which have wider crowns FL: Mand I or Max I?
Mand I
Which incisor has root that is only slightly longer than crown?
Max CI

Oval
Max CI cingulum located
distally to midroot axis

center-at midroot axis
On all anterior teeth which CEJ curves more?
mesial CEJ
Root depression on Max CI
none
rarely shallow depression on mesial
