Lingual Bracket

Abstract

A lingual bracket includes a bracket base (1), a bracket wing (2), and a spring (3), the bracket base (1) has an upper surface with an end provided with a fixed wing (11) and the other end provided with an auxiliary tube (12), and a bottom face provided with a non-skid bonding face (13); the bracket wing (2) has an insertion leg (21) and a wing portion (22), and can be positioned on the fixed wing (11) by the spring (3) sleeved on the insertion leg (21); a longitudinal groove (111) is provided along a central axis of the fixed wing (11) of the bracket base (1), and a transverse groove (112) is provided at a rear end face of the fixed wing (11); and the insertion leg of the bracket wing (2) has the width equivalent to that of the longitudinal groove (111), and can be placed in the longitudinal groove (111), a joint of the insertion leg (21) and the wing portion (22) is provided with a wide extension part (23), and when the insertion leg (21) is placed in the longitudinal groove (111) and pushed forward by the spring (3), the wide extension portion (23) can be interposed into the transverse groove (112) to form a positioning structure. The two crisscrossed grooves in the bracket base (1) are utilized to form the constraint for the bracket wing (2), enabling the features of an ingenious design, a simple structure, easy machining, and a convenient clinical operation.
