The first connecting portion 306 (ie, the first right connecting portion) on the first right cheek surface 100b is coupled to the portion 406 (ie, the second left connecting portion), and the second right cheek surface 200b on the second right cheek surface 200b. Connected to the connecting portion 406 (that is, the second right connecting portion) (for example, three elastic members 500 are respectively installed on the left cheek surface and the right cheek surface of the first and second retainers 100 and 200). Therefore, the elastic force of the elastic member 500 causes the second retainer 200 to move backward and upward (along the direction between the Y axis and the Z axis) relative to the first retainer 100, or forward and downward. (Along the direction between -Y axis and -Z axis It moved to Te). Thus, the relative position between the patient's mandible 20 connected to the second retainer 200 and the patient's maxilla 10 connected to the first retainer 100 is adjusted, thereby achieving orthognathic correction.

  When the first and second connecting portions 306 and 406 on the corresponding cheek surfaces of the first retainer 100 and the second retainer 200 of the elastic member 500 are different from each other, the second retainer 200 is changed to the first retainer 100. On the other hand, an elastic force that moves backward and upward (along the direction between the Y axis and Z axis) or forward and downward (along the direction between the −Y axis and the −Z axis) may be generated. . In some embodiments, the elastic member 500 is an annular material, such as a rubber band or a spring coil, made of a Ni-Ti alloy material having the same or different elastic force.

  In particular, when the number and the elastic force of the elastic members 500 arranged on the left and right cheek surfaces of the first retainer 100 and the second retainer 200 match each other, the left and right cheek surfaces of the first retainer 100 and the second retainer 200 are aligned. The forces received are matched so that the mandible 20 connected to the second retainer 200 is connected to the first retainer 100 along the vertical central axis C (parallel to the Y axis in FIG. 2) of the patient's oral cavity. 2 and the relative movement between the mandible 20 and the maxilla 10 in the direction between the Y axis and the Z axis in FIG. 2 or between the −Y axis and the −Z axis.
