What Is the Anatomic Crown? The crown is the surface of the tooth that lies above the gumline, and it contains three different dental layers: enamel, dentin and pulp..
What is the crest of contour teeth?
The crest of curvature (contour) is defined as the widest area of the crown of the tooth when viewed from the facial (or lingual) or proximal (mesial or distal). Each tooth has a distinct location for the crest of curvature and it is based on the crown divided into thirds..
Where is the alveolar crest?
The crest of the alveolar bone is normally located around 1 mm below the cemento-enamel junction. Blood vessels and nerves run through the alveolar bone and perforate the cribriform plate. The majority of these blood vessels and nerves supply the periodontal ligament..
Anatomic Crown Definition An Anatomic Crown is the enamel-coated upper part of your teeth, including the gum-covered regions. The three layers of the anatomic crown are dentin, enamel, and pulp.
Ridges are any linear, flat elevations on teeth, and they are named according to their location. The buccal ridge runs cervico-occlusally in approximately the center of the buccal surface of premolars. The labial ridge is one that runs cervico-incisally in approximately the center of the labial surface of canines.

What is the alveolar crest?
The alveolar crest is the most coronal portion, or the top, of the alveolar process
It is an extension of both the mandible and maxilla and holds the tooth sockets
The alveolar crest is often the first portion of the alveolar process that is damaged by periodontal disease and is therefore the first bone that is lost
What is the difference between ampullar crest and dental crest?
ampullar crest ( ampullary crest) the most prominent part of a localized thickening of the membrane that lines the ampullae of the semicircular ducts, covered with neuroepithelium containing endings of the vestibular nerve dental crest the maxillary ridge passing along the alveolar processes of the fetal maxillary bones
What is the difference between dental crest and iliac crest?
dental crest the maxillary ridge passing along the alveolar processes of the fetal maxillary bones iliac crest the thickened, expanded upper border of the ilium
The outer surface of the crown is made of enamel. Just beneath the enamel is dentin, a substance harder than bone. The gum surrounds the base (root) of the tooth. The root of the tooth extends down into the jawbone.The crown of the tooth is the visible part of the tooth in the mouth, while the root is hidden beneath the gingiva and alveolar bone. It has a pearl white to yellow colour depending on the thickness of the enamel, the age of the patient, their oral hygiene and lifestyle choices.
Dental crest anatomy definition
The external occipital crest is part of the external surface of the squamous part of the occipital bone. It is a ridge along the midline, beginning at the external occipital protuberance and descending to the foramen magnum, that gives attachment to the nuchal ligament. It is also called the median nuchal line.
