Granted: 2021-07-06
Abstract: The present invention relates to an indirect attachment jig for orthodontic bracket formed integrally wiht bite block, which is formed by forming a jig for indirectly attaching an orthodontic bracket integrally with a bite block and producing the same through 3D printing so that not only can the jig be made to precisely fit the patient's individual tooth shape, but also it allows an operator to more easily attach the bracket to multiple teeth at the same time in an accurate position while the patient is biting the opposing tooth by the bite block when the orthodontic bracket is attached. In addition to making an indirect attachment jig for a bite block-integrated orthodontic bracket by 3D printing method, the bracket can be accurately attached to the teeth, and by connecting the orthodontic jig in the transverse direction and forming a bite block as an integral part, the patient can occlude the jig to stabilize the entire jig, allowing the operator to use both hands freely and use other instruments such as a light curing machine more efficiently. In a state in which the patient occludes the bite block and a fixed part, the orthodontic device can be attached at a more accurate position using occlusal force to stabilize the entire device by attaching and operating multiple teeth at once. Thus it has the effect of shortening the treatment time of the patient.
