Mandibular Central Incisor Arch Traits Flashcards
Which mandibular incisor is bigger?
lateral>central
Roots are wider in which directions?
wider labiolingually
narrower mesial-distally
When do the Mandibular C. Incisors erupt?
6-7 years
at what age is the root competed
at age 9
the mandibular central incisor is also known as what kind of tooth?
a symmetrical tooth
Contacts from labial view
mesial and distal are both at incisal 1/3 at the same height
Why is the tooth symmetrical?
because the mesial/distal outlines converge equally to cervical
Where does the root incline?
distally
CEJ shape from the lingual view
more curvature due to convergence of crown lingually
Crests of curvature (height of contour) from mesial view
lingual and facial are at the cervical 1/3
Incisial edge is aligned where from the long axis of the tooth?
incisial edge is slightly lingual
Developmental groove shape in distal view
developmental groove is deeper in this aspect
From the incisal view where is the cingulum placed?
placed off to the distal
