Mandibular Arch

 

a supporting element of the visceral skeleton in gnathostomatous vertebrates, including humans. The mandibular arch is situated directly in front of the sublingual arch. In the course of evolution, the mandibular arch differentiated into the primary upper jaw (palatoquadrate cartilage) and primary lower jaw (Meckel’s cartilage).

After this phase it is essential to assess the patient's initial mandibular arch form (tapered, oval, or square) in order to use the most appropriate in contouring the archwires throughout therapy, thus significantly contributing to the post-treatment stability (INTERLANDI, 1978; IZARD, 1927; MCLAUGHLIN; BENNETT, 1999; RICKETTS, 1978; STEADMAN, 1961; STRANG, 1946; TRIVINO et al., 2008; ZACHRISSON, 1998).
The developing jaw articulation is still the neural crest bone of the mandibular arch, which remains uncovered by dermal bone posteriorly.
