The present invention relates to a transfer jig for a bracket or a tube to perform an orthodontic operation to an actual tooth of a patient by an indirect attachment using an electronic mold, the transfer jig comprising a fixing unit which has a fixing base including a contact surface corresponding to the actual teeth; and a moving unit which has a first side coupled with the fixing unit and a second side detachably attached to at least one of the bracket and the tube. That is, the transfer jig for the bracket or tube includes the fixing unit and the moving unit which are detachably attached thereto. Here, the fixing unit is manufactured by a small/high precision CNC equipment installed in individual dental clinics. Meanwhile, the moving unit is ready-made and supplied to the dental clinics. The moving unit includes a strong and wear resistant material and can be reused. The moving unit is attached to a slot of the bracket or tube in the same direction as the coupling direction of the arch wire. The moving unit is rotatably coupled with the fixing unit. Thus, manufacturing costs and time of the transfer jig for the bracket or tube are reduced. Also, if the bracket or tube is attached to a patient, precision and treatment time may improve. Compared to other indirect attachments, the bracket or tube attached to the teeth provides improved adhesion which is similiar to that of direct attachment. If the bracket or tube is attached again to the teeth as if fails to be attached thereto, high precision can be maintained. |
