Abstract
An orthodontic anchoring screw including a threaded shank, extending prevalently along a longitudinal axis, and a head provided with a seat extending substantially along a housing direction perpendicular to the axis and intended to house a metallic wire for imposing a correction action on a tooth. The head has engagement mechanism for holding the wire in the seat, which includes two shaped appendages, each with a shaped shank having a widened head fixed on top. The heads define between them a slit for inserting the wire, extending prevalently along a transversal direction, perpendicular to the longitudinal axis and inclined with respect to the housing direction of the seat. The shanks and the heads define together the seat, communicating with the slit to receive the wire.
