  2. Dental arch - Wikipedia

    en.wikipedia.org/wiki/Dental_arch

    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 ...

    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.

  4. Pharyngeal arch - Wikipedia

    en.wikipedia.org/wiki/Pharyngeal_arch

    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 [11]), and palate while the mandibular process becomes the mandible or lower jaw.

  5. Maxilla - Wikipedia

    en.wikipedia.org/wiki/Maxilla

    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. [3] [4] The two maxillary bones are fused at the intermaxillary suture, forming the ...

    4) Maxillary / Mandibular Arch. Assess each arch and identify whether there are any signs of occlusal disharmony, overloading, tooth migration, wear, craze lines, cracking or mobility (not due to periodontal causes). [25] Abfraction, faceting and possible vertical enamel fracture lesions should also be noted if present. [30] 5) Contacts in ICP

  7. Dental midline - Wikipedia

    en.wikipedia.org/wiki/Dental_midline

    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.

  8. Antegonial notch - Wikipedia

    en.wikipedia.org/wiki/Antegonial_notch

    The facial artery typically crosses the inferior border of the mandible just anterior to the masseter muscle's insertion. In most instances, this crossing occurs at or in close proximity to the antegonial notch. This anatomical association has clinical relevance in various surgical procedures involving the face and mandible.

  9. Mandible - Wikipedia

    en.wikipedia.org/wiki/Mandible

    The mandibular alveolar process can become resorbed when completely edentulous in the mandibular arch (occasionally noted also in partially edentulous cases). This resorption can occur to such an extent that the mental foramen is virtually on the superior border of the mandible, instead of opening on the anterior surface, changing its relative ...
