Incisal View

The shape of the crown in the incisal view tends to be triangular like all of the incisors or it can have a diamond-shape like the canines. The crown tapers towards the lingual.

Facial Outline of Crown

The crown is evenly convex in this view and tends to be more convex than the maxillary central incisor.

Lingual Outline of Crown

The cingulum is prominent in this view but is more narrow than the maxillary central incisor or the canine.

Mesial Surface of the Crown

The crown is generally convex.

Distal Surface of the Crown

The crown surface is generally convex.

Incisal Ridge

In this view, the incisal ridge is centred labiolingually or is slightly labial to a line bisecting the root. The difference between the labiolingual and mesiodistal widths should be noted as the difference is less (6.8mm mesiodistally vs 6.4mm labiolingually) than the maxillary central incisor. The mesiodistal width is greater than the labiolingual dimension only by 0.4mm.

Root

The root is not visible in this view.
