The maxillary lateral incisors are a pair of upper teeth that are located laterally (away from the midline of the face) from both maxillary central incisors of the mouth and medially (toward the midline of the face) from both maxillary canines.

The maxillary lateral incisor tooth is one of the two incisor teeth that are found in a quadrant of the maxillary dental arcade. It includes the following bony features: - parts: crown, root, and cervical line; - surfaces: incisal margin, and labial, lingual, mesial, and distal surfaces; - landmarks: cingulum, marginal ridges, and lingual fossa.

The maxillary lateral incisor is very similar to the maxillary central incisor. However, its incisocervical length is usually longer than the mesiodistal length. The maxillary central incisor is approximately the same length in both directions. Also, the maxillary lateral incisor has a longer root, and its incisal angles are more rounded.

2023年10月30日 · Each incisor has five surfaces, each one named according to the anatomical structure that it faces: Labial surface - faces the lips. Lingual surface - faces of the mandibular incisors face the tongue. The corresponding maxillary incisors have a palatal surface instead of a lingual one that faces the hard palate of the oral cavity.

Describe the form and features of maxillary incisors in detail, using the following terms: height of contour, outline form, cervical outline, imbrication lines, lingual fossa, and cingulum. Describe the difference between the central and lateral incisors in all aspects.

2020年10月16日 · Maxillary lateral incisor is the second tooth from the midline of the maxillary arch. It supplements the maxillary central incisors in function. It resembles maxillary central incisor but it differs in relation to the dimension of crown and length of the root. Crown of the tooth is narrower mesio-distally.

2023年10月30日 · There are twenty deciduous teeth in total, which means four medial incisors, four lateral incisors, four canines and eight molars. Each of the four oral quadrants that are separated by the midline and into the upper and lower jaw contain five teeth each.
