Further, by limiting the distance between the corresponding same points on adjacent barbs, as well as the width of the connecting plate, and the distance between the corresponding same points on adjacent card slots, it is convenient to The orthodontic treatment plan respectively determines the mandibular leading target amount and the lower anterior tooth depression target amount, and determines the required adjustment direction and adjustment displacement according to the leading target amount and depression target amount, and then determines the push rod according to the adjustment direction and adjustment displacement amount. direction and amount of displacement, and determine the height of the protruding structure; specifically, by moving the push rod, the displacement of the push rod is adjusted, and in the process of moving the push rod, several barbs pass through the hole, and then correspondingly remove the same number of connecting plates, so that the plate structure can always fit the body of the maxillary retainer, and it is also convenient for the doctor to observe the number of barbs passing through the hole, that is, the displacement of the push rod. , because the distance between adjacent draw-in slots is limited, by observing the hooks adjusted to the corresponding draw-in slots, it is more intuitive to observe the adjustment amount of the guide plate in the vertical direction, thereby improving the adjustment of the mandibular leading amount and the lower front. The convenience of tooth pressure reduction;

5. Further, fix the push rod on the concave structure. Specifically, the push rod and the concave structure can be integrated, or the push rod and the concave structure can be fixedly connected so that it cannot be disassembled, so that it is easy to push The rod moves together with the concave structure, which improves the stability of the synchronous movement of the push rod and the concave structure; or, by setting a blocking piece, and the blocking piece is detachably connected with the push rod, when the push rod and the barb penetrate the first After a through hole, connect the blocking piece to the push rod. Specifically, make the blocking piece clamp the push rod so that it is firmly fixed on the push rod, or the push rod is arranged on a matching groove that matches the blocking piece. , the blocking piece is in the matching groove and clamps the push rod, so that the blocking piece and the push rod can be separated easily, so as to facilitate the disassembly of the guide plate and the holder body; the guide plate can be selected according to the needs of the patient, and when the patient does not need to use the guide plate, Improve patient comfort by decoupling the guide from the retainer body.
