The dental arches are the two arches (crescent arrangements) of teeth, one on each jaw, that together constitute the dentition.In humans and many other species, the superior (maxillary or upper) dental arch is a little larger than the inferior (mandibular or lower) arch, so that in the normal condition the teeth in the maxilla (upper jaw) slightly overlap those of the mandible (lower jaw) both ...
In vertebrates, the maxilla (pl.: maxillae / mækˈsɪliː /) [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. [3][4] The two maxillary bones are fused at the intermaxillary suture, forming the anterior ...
The mandibular first molar is the tooth located distally from both the mandibular second premolars of the mouth but mesially from both mandibular second molars. It is located on the mandibular arch of the mouth, and generally opposes the maxillary first molars and the maxillary 2nd premolar. This arrangement is known as Class I occlusion.
This arch divides into a maxillary process and a mandibular process, giving rise to structures including the bones of the lower two-thirds of the face and the jaw. The maxillary process becomes the maxilla (or upper jaw, although there are large differences among animals [10]), and palate while the mandibular process becomes the mandible or lower jaw.
Occlusion (dentistry) Occlusion, in a dental context, means simply the contact between teeth. More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest. Static occlusion refers to contact between teeth when the jaw is closed and ...

[edit on Wikidata] The alveolar process (/ ælˈviːələr, ˌælviˈoʊlər, ˈælviələr /) [1] is the portion of bone containing the tooth sockets on the jaw bones (in humans, the maxilla and the mandible). The alveolar process is covered by gums within the mouth, terminating roughly along the ...
The maxillary and mandibular prominences are derived from the first arch. The maxillary prominence is initially located superior/lateral to the stomodeum while the mandibular prominence is located inferior to it and will fuse early on. Nasal placodes originate on the frontonasal prominence from the ectoderm.
The dental midline is the midsagittal line of maxillary and mandibular dental arches possessing teeth of ideal size, shape, and position, when situated in maximum intercuspation. Each arch also possesses its own midline, which can be used to refer to the location of contact between the mesial surfaces of the central incisors. Thus, if an ...
