In a one-couple system there is a single point of application of force system which allows one to devise what type of force is being generated. For example, in a segmental intrusion arch, the arch is tied to a base archwire anteriorly and engaged into a tube in the posterior molar. This produces only a force in the anterior but a force and a couple in the posterior at the molar. Thus a couple is generated only at one end of the intrusion arch and thus this type of system is known to be one … WebNov 12, 2024 · Connecticut Intrusion Arch (1998) and Connecticut New Intrusion Arch (2005) both were introduced by Nanda et al. for intrusion of anterior teeth.
