Abstract

An orthodontic bracket including a body (1) having a mesiodistal slot (10), a base (11), and a plurality of tie wings (12, 120) mainly developed along an occlusal-gingival direction. The tie wings are provided two-by-two on opposite sides in relation to the slot (10) and partially emerging over a labial side (L) of the body (1). The slot (10) is apt to receive an archwire (2). The tie wings (12, 120) protrude externally from the body (1) and towards the base (11), feature a curved surface (121) whose concavity is turned towards the same base (1) and constitute a support for an element (3) apt to prevent the archwire (2) from coming out of the slot (10). The element (3) features a planar portion intended to slide above, and parallel to, the labial side (L) of the body (1) and a flexible and elastic arm (33) having a portion (34) which is securable to the surface (121) of two tie wings (12) resulting on the same side in relation to the slot (10). The portion (34) of the flexible arm (33) moves along a curved path corresponding to the profile of the lower side (LT) of the tie wings (12) while the planar portion of the element (3) slides above the labial side (L) of the bracket body (1).
