Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.) Tooth formation begins before birth, and the teeth's eventual morphology is dictated
German illustration (c. 1910) depicting interior of jawbones, with nerves, veins, and arteries leading to teeth—and thus the alveolar areaOn the maxilla, the alveolar process is a ridge on the inferior surface, making up the thickest part of the bone.
The distinction is one of anterior (front of the body) versus posterior (rear of the body). The distinction holds in both the upper jaw ( maxilla ) and lower jaw ( mandible ). As a rough guide, it can be said that the anterior teeth are tailored to biting (breaking the food into chewable chunks) [ 1 ] whereas the posterior teeth are tailored to ...
Anchorage can be used from many different sources such as teeth, bone, implants or extra-orally. [2] [3] Certain factors related to the anatomy of teeth can affect the anchorage that may be used. Multi-rooted, longer-rooted, triangular shaped root teeth usually provide more anchorage than the single-rooted, short-rooted and ovoid rooted teeth.
Dental alveoli (singular alveolus) are sockets in the jaws in which the roots of teeth are held in the alveolar process with the periodontal ligament. The lay term for dental alveoli is tooth sockets. A joint that connects the roots of the teeth and the alveolus is called a gomphosis (plural gomphoses). Alveolar bone is the bone that surrounds ...
Although technically referring only to anterior teeth (where the lips (labia) are present instead of cheeks), use of the term labial has inaccurately extended to all teeth, anterior and posterior (instead of vestibular).

In vertebrates, the maxilla (pl.: maxillae / m æ k ˈ s ɪ l iː /) [2] is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth.
