300 Dental Anatomy: Incisors Flashcards
The primary function of incisors is:
Biting
Which tooth has the greatest facio-lingual axial inclination?
Maxillary central
____ has the greatest cervical curvature (on mesial) of any other tooth
Maxillary central
The ONLY anterior teeth that are wider M-D than F-L
Maxillary centrals
Has greatest M-D crown dimension of any ANTERIOR tooth
Maxillary centrals
Has measurement that is nearly identical for Inciso-Cervical vs Mesio-distal
Maxillary centrals
Contact between a max central and lat incisor has what effect on the embrasures?
lingual embrasure larger than the facial
Incisal embrasure between the maxillary centrals is ___ than between the central and the lateral.

wider
What is visible on the mandibular lateral incisor when looking at it from the mesial?
DMR (distal marginal ridge)
