Short Description
The curved structure formed by the upper or lower set of teeth within the jaw.
Long Description
In dentistry, an arch refers to the curved arrangement of teeth in either the upper (maxillary) or lower (mandibular) jaw. Each arch contains one half of the dentition and works in coordination with the other for chewing and speech.
Dental professionals refer to upper and lower arches when planning treatment, placing appliances, or discussing orthodontic alignment. Each arch is divided into quadrants to further describe the location of teeth.
Arches can be restored or replaced with prosthetic devices such as dentures or bridges when natural teeth are lost. Maintaining proper arch form and symmetry is important for oral function, comfort, and aesthetic balance.
