arch depth the perpendicular distance from a point between the central incisors to a line connecting the mesial contacts of the first permanent molars; see arch length
arch length same as arch depth; but note that 'arch length' is often used as a synonym for arch circumference or arch perimeter
arch wire a wire applied to two or more teeth through fixed attachments to cause or guide orthodontic tooth movement
