What is incisal aspect?
Incisal aspect. The incisal view of this tooth considers the portion of the tooth visible from the side where the incisal ridge is located. From this angle, only the crown of the tooth is visible, and overall, the tooth looks bilateral.
Which teeth have incisal edges?
The maxillary canines are the longest teeth in the mouth. They have a single cusp with mesial and distal ridges forming an incisal edge.
What is incisal ridge?
The incisal ridge is that portion of the crown which makes up the complete incisal portion. When an incisor is newly erupted, the incisal portion is rounded and merges with the mesioincisal and distoincisal angles and the labial and lingual surfaces. This ridge portion of the crown is called the incisal ridge.
How many lobes are in the maxillary central incisor?
four lobes
Drawings (A), (B), and (C) show the facial, mesial, and incisal views of a maxillary central incisor that, like all anterior teeth, forms from four lobes. The lingual cingulum develops from one lobe (labeled 4) seen in views (B) and (C).
What is incisal angle of a tooth?
The incisal edge is the biting edge of an incisor or canine. The incisal angle is the angle between the incisal edge and the mesial or distal surface of an anterior tooth. The incisal guide table forms the base for the incisal guide pin on an articulator.

How many lobes form an incisor?
All anterior teeth are formed from four centers of development, referred to as lobes. Three are located on the facial side of the tooth, and one on the lingual side. The cingulum forms from this lingual lobe of development.
What are the lobes of teeth?
While mandibular first premolars develop from four lobes (mesial, distal, buccal, and lingual) just like the anterior teeth and maxillary premolars, mandibular second premolars often develop from five lobes (mesial, buccal, distal, mesiolingual, and distolingual lobes).
What is incisal guidance?
Incisal guidance is the path on the lingual surface of the maxillary anterior teeth along which the mandibular anterior teeth glide, in neutro- or distoocclusion.
