The utility model discloses a low-resistance
impact-resistant strip-shaped straight wire buccal tube, and belongs to the technical field of orthodontic instruments. The buccal tube comprises a buccal tube body provided with an arch wire channel, the inner side face of the buccal tube body is a bonding face without an outwards-protruding
flange, the
peripheral edge of the buccal tube body is flush with the side face of the tube body, and the attacking face is obviously reduced; the streamline arc-shaped surface which is in smooth transition from the top to the outer side is arranged on the outer side close to the tooth
occlusal surface, so that food can be guided to slide down along the arc-shaped surface, and the
impact force is reduced. The outer side surface and / or the lower side surface of the buccal tube body are / is a plane, so that
tweezers or pliers can stably clamp the buccal tube body; and the main body of the traction hook is positioned in the outline projection range of the buccal tube, so that the resistance is prevented from being increased due to outward projection. Through the combination of the
flange-free bonding surface, the streamline arc-shaped surface and the drainage channel, the problem that a traditional buccal tube is prone to falling off due to
impact of food is solved, meanwhile, the operation efficiency and the comfort of a patient are improved due to the
integrated design of the plane clamping structure and the traction hook, and the buccal tube is suitable for various orthodontic correction requirements.
