IMPROVEMENTS INTRODUCED IN A LINGUAL ORTHODONTIC TUBE

摘要

improvements made in lingual orthodontic tube, more precisely it is lingual orthodontic tube (1), notably developed to facilitate the assembly and locking of orthodontic accessories; said lingual tube (1) is formed into a single piece (2) comprising an oblong base (2a) slightly arched in the longitudinal direction and in the central portion of which a pair of rectangular cutouts (2b) are practiced, which are arranged spaced apart, configuring a central wall (2c); aligned with said cutouts (2b) and starting from the lateral ends (2d) of said base (2a), a projection in the form of a receptacle (2e) develops, with a "c" section facing the base (2a), configuring a cage (g) with a frontal opening (af) and a rear opening (ap) for the coupling of orthodontic accessories, such as the extreme member (bp ') of the palatal bar (bp); the front face of the cage (g) includes a central cutout (2f) practiced on the upper wall (2g) of the receptacle (2e), while on each edge (2h) of each opening (af) and (ap) central deformations are predicted (2i), in a "v" shape, which develop towards the arched base (2a) forming locking elements (et) of the end (bp ') of the palatal bar (bp); from the outer face of one of the side walls (2j) of the cage (g) a hook (gn) of "t" shape develops, formed by a tubular portion (2i) in whose extreme free portion is the orthogonal branch (2m), oblong and ellipsoidal.
