"ARRANGEMENT INTRODUCED IN BRACKET WITH CURVILINEAR RIDGES", is constituted by one bracket for fixed braces that belongs to the orthodontics and, unlike the brackets that exist in the market, it has an unique geometry with specific functionalities, such as a clip that detaches close to the basis, rounded edges among other parameters; the bracket with curvilinear ridges (1) is composed of two pieces, the clip (2) or lock, which encapsulates the traction wire, and the main structure, which is monoblock and has all corners rounded; the main structure shows off a squared basis (3) topped by an upper-basis (4) that covers all the width and only a central third of the depth, being its height proportional to the width and depth; above the upper-basis (4) an "U" structure (5) is developed with a quadratic profile that has four hooks (6) in its upper vertexes, with concave upper portion and convex bottom portion (7), being one of these hooks (6) equipped, at the head and in material continuity, by a spherical hook (8) preceded by a connection segment (9) with a rectangular flat profile, etc.. |
