Flashcards in Mandibular Central Incisor Arch Traits Deck (13):
1

Which mandibular incisor is bigger?

lateral>central

2

Roots are wider in which directions?

wider labiolingually
narrower mesial-distally

3

When do the Mandibular C. Incisors erupt?

6-7 years

4

at what age is the root competed

at age 9

5

the mandibular central incisor is also known as what kind of tooth?

a symmetrical tooth

6

Contacts from labial view

mesial and distal are both at incisal 1/3 at the same height

7

Why is the tooth symmetrical?

because the mesial/distal outlines converge equally to cervical

8

Where does the root incline?

distally

9

CEJ shape from the lingual view

more curvature due to convergence of crown lingually

10

Crests of curvature (height of contour) from mesial view

lingual and facial are at the cervical 1/3

11

Incisial edge is aligned where from the long axis of the tooth?

incisial edge is slightly lingual

12

Developmental groove shape in distal view

developmental groove is deeper in this aspect

13

From the incisal view where is the cingulum placed?

placed off to the distal
