Description

Technical Field

[0001] The utility model relates to the technical field of dentistry, in particular to a torque device used for orthodontics. Background Art

[0002] Torque is an important concept in orthodontics. It refers to the moment of force acting on the teeth, which can cause the teeth to rotate around a certain axis. The application of torque is to adjust the relative angles of the clinical crown and root of the teeth to ensure that the teeth can reach the correct axial position during the correction process. This operation is achieved by bending the orthodontic arch wire. The doctor can apply different degrees of torque to the arch wire as needed, and then use specific orthodontic accessories such as torque springs, elastic rubber rings or customized brackets to assist.

[0003] Doctors often use a torque device to clamp the arch wire, bend it into a specific curvature, and then install a hook made of the arch wire and connect it to the teeth. This torque device is mostly a medical forceps body to facilitate clamping and locking. Because the arch wire is thick or thin, there is a possibility of slipping between the ordinary forceps head slot, making it difficult to accurately bend the arch wire.

[0004] Now, a new type of torque device for orthodontic use is proposed to solve the above problems. Utility Model Content
