Study Notes
Maxillary Central Incisors
- The proximal contact area is likely located at the mesial third of the clinical crown, near the cervical line.
- The feature NOT typically observed on the labial aspect of the maxillary central incisors is a prominent labial ridge.
- The lingual fossa of the maxillary central incisors is characterized by a prominent, deep, and narrow V-shaped groove.
- The incisal ridge of the maxillary central incisors is typically straight, and its edges are sharp.
- The mesial cervical line of the maxillary central incisors is likely located at or near the cervical third of the clinical crown.
- The landmark on the maxillary incisor that is a smaller elevation on some portion of the crown produced by an extra formation of enamel is a mammelon.
- The mesial height of contour (contact area) on the labial aspect of the maxillary incisor is located at the junction of the cervical and middle thirds of the crown.
- The root of the maxillary incisor is single-rooted, and it is approximately 2-3 times longer than the crown.
- The bulk of the cervical third of the lingual surface of the maxillary incisor is made up by the cingulum.
- The distal height of contour (contact area) on the labial aspect of the maxillary incisor is located at the junction of the middle and incisal thirds of the crown.
