Transpalanance is the fusion of the trans palatine arch with the Nance Button. This anchorage is used, as the chromosome Arch, in cases of dental overcrowding and facial change as an objective. It is a good maximum anchorage option for the upper maxilla, where the Nance button has an acrylic dab reclined on the anterior, superior and medial region of the palate; the transpalatine arch, the dentally supported part of the appliance, is made with 0.036" round stainless steel wire.
