Flashcards in Maxillary Lateral Incisor Arch Traits Deck (14):
1

Eruption stage of Max. L. Incisor

8-9 years

2

at what age is the root completed

age 11

3

what are the maxillary laterals also called?

gender teeth
-more rounded is more feminine

4

size compared to centrals?

smaller except root may be longer but not always

5

what part of the tooth is very rounded from the labial view?

MI and DI
-DI is more rounded because distal contacts are more cervically placed

6

Mesial contact from labial view?

junction of incisal and middle 1/3

7

Distal contact from labial view?

center of middle 1/3

8

Root travels where from labial view?

tend to incline distally

9

from the lingual view why is the MMR and DMR more prominent?

due to deeper fossa/pit

10

CEJ shape from lingual view compared to C. Incisor

less curvature

11

crest of curvature from mesial view

slightly more incisally placed compared to central (in cervical 1/3)

12

from the distal view which ridge gives a thicker appearance?

the distal marginal ridge

13

From the Incisal view the cingulum is where to the midline?

distal to midline

14

Anomalies/Variations of max. incisors

labial outline-centrals can become tapered, squared, or ovid & laterals can become pegged
labial lobes-centrals have deep grooves
mamelons-vary in number
Cingulum- The central has a talon cusp which interferes with person closing
