Buccal tube

The utility model relates to a buccal tube which comprises a base and a buccal body fixed on the base, and a groove used for mounting an arch wire is formed in one side, far away from the base, of thebuccal body; a first ligation wing and a second ligation wing are arranged on the two sides of the groove respectively, and a traction hook is connected to the first ligation wing. A through wire penetrating channel is formed in the side, facing the base, of the buccal surface body, and the wire penetrating channel is perpendicular to the groove. According to the ligature wire, the wire penetrating channel is arranged, so that the ligature wire can lock the arch wire through the wire penetrating channel, the first ligature wing and the second ligature wing, and the structural stability of thearch wire is improved. 本实用新型涉及一种颊面管，其包括底座和固定于底座上的颊面体，颊面体上远离底座一侧开设有用于安装弓丝的槽沟；槽沟的两侧分别设置有第一结扎翼和第二结扎翼，且第一结扎翼上连接有牵引钩；颊面体朝向底座的一侧开设有贯通的穿丝通道，穿丝通道和槽沟相互垂直设置。本实用新型设置穿丝通道，使得结扎丝可以通过穿丝通道、第一结扎翼和第二结扎翼对弓丝进行锁定，从而提高弓丝的结构稳定性。
