    摘要： Disclosed is a traction/locking element, a traction/locking set, an orthodontic bracket, an orthodontic bracket setup and a tooth orthodontic method. The traction/locking element comprises a strip-shaped nail body (10). The nail body (10) has a cross-sectional area of 0.06-2.5 square millimetres, and a length of 0.8-4.5 millimetres. The front end of the nail body (10) is a first fixed end(11), and the rear end thereof is a first screwing end(12). The first fixed end (11) is provided with connecting external screws (111), with the external diameter of the connecting external screws (111) being 0.2-1.6 millimetres. At least the end position of the first screwing end (12) is provided with a first force applying surface (121). The traction is performed in time according to the traction opportunity of orthodontics, and the traction is very reliable, reducing the discomfort in the oral cavity. With a breaking part and a disassembly and assembly tool, the assembly and disassembly are very convenient.

    摘要： The present invention relates to an orthodontic archwire stop (20) having a body (26) made of a shpae memory metal alloy. The body has first and second, spaced apart arm portions (40, 42) connected to each other. Each arm portion includes a jaw portion (44) having an inner, arch wire-gripping, surface (80). The inner gripping surfaces are disposed opposite one another in spaced relation with a station defined therebetween for receiving the arch wire. At least a portion of the station is sized smaller than the arch wire. The arm portions are resiliently deflectable outwardly away from each other to admit the arch wire into the station. Once seated in the station, the arch wire is tightly held by inner gripping surfaces so as to resist displacement of the gripping device relative to the arch wire.

    摘要： The present invention relates to an orthodontic gripping device having a body made of a superelastic metal alloy, cold worked titanium beta III, or solution heat treated and aged titanium beta III. The body has first and second, spaced apart arm portions connected to each other. Each arm portion includes a jaw portion having an inner, arch wire-gripping, surface. The inner gripping surfaces are disposed opposite one another in spaced relation with a station defined therebetween for receiving the arch wire. At least a portion of the station is sized smaller than the arch wire. The arm portions are resiliently deflectable outwardly away from each other to admit the arch wire into the station. Once seated in the station, the arch wire is tightly held by inner gripping surfaces so as to resist displacement of the gripping device relative to the arch wire.

    摘要翻译： 本发明涉及具有由超弹性金属合金，冷加工钛βIII或溶液热处理和老化的钛βIII制成的主体的正畸夹持装置。 主体具有彼此连接的第一和第二，间隔开的臂部分。 每个臂部分包括具有内部弓形线夹紧表面的钳口部分。 内夹持表面彼此相对地设置成与其间限定的站间隔开，用于容纳拱形线。 站的至少一部分的尺寸小于拱形线。 臂部分可弹性地偏离彼此向外远离以允许弓丝进入工位。 一旦坐在车站中，拱形线被内部夹紧表面紧紧地保持，以便阻止夹持装置相对于拱形线的位移。
