Referring to fig. 1 and 6, it can be understood that, since the force application direction of the engaging member 30 (especially the arch expanding rod) is always along the two outer sides (i.e. labial sides) of the dental arch, after the end of the engaging member 30 is placed into the insertion cavity 13, the naturally occurring movement deformation trend of the engaging member 30 is directed to the direction of the back-off groove 14, and the engaging member 30 naturally enters into the back-off groove 14 and always abuts against the back-off groove 14. When the connector 30 is inserted into the insertion cavity 13, the insertion direction is along the gingival and jaw directions; the engaging member 30 that is reversely buckled in the groove is fixed in the gingival jaw direction due to the blocking limit of the reverse concave structure, so that the engaging member 30 cannot be separated from the groove, and the engaging member 30 is always stably connected with the lingual orthodontic accessory 10.
The utility model has two using modes:
(1) When the lingual accessory is matched with the connecting piece 30 (such as the expansion bow rod and the arch wire), the tail end of the connecting piece 30 is placed into the inserting cavity 13, and as the force application direction of the connecting piece 30 (especially the expansion bow rod) is always towards the labial direction, the inserting cavity 13 is communicated with the back-off groove 14, and the back-off groove 14 is positioned at the labial direction of the inserting cavity 13, the connecting piece 30 placed into the inserting cavity 13 enters into the back-off groove 14 along with the back-off groove 14 and is always abutted against the inner side wall of the back-off groove 14. Because the undercut structure is arranged in the undercut groove 14, the tail end of the connecting piece 30 is always buckled in the lingual orthodontic accessory 10 and cannot be separated, and compared with the traditional hook type connection mode, the connecting piece 30 provided by the utility model adopts embedded installation, has the effects of stable connection, difficulty in loosening, convenience in installation and stable and consistent force application, and further improves the correction effect. (2) When the connecting piece 30 is not needed, the lingual orthodontic accessory 10 can also be independently used as the lingual accessory, thereby having the multifunctional effect and improving the problem of single function of the existing orthodontic accessory.
Specifically, referring to fig. 4, the structure of the undercut groove 14 includes an integrally formed part: the receiving portion 141 and the channel portion 142 are respectively configured to receive the end of the engaging member 30 and the middle section of the engaging member 30. It should be noted that, in the present embodiment, the engagement member 30 is generally a strip structure, and the end of the engagement member is provided with a protrusion 31, and the outer diameter of the protrusion 31 is larger than the outer diameter of the middle section. One end of the channel 142 is connected to the accommodating portion 141, and the other end is connected to the opening of the cavity 12; the shape of the receiving portion 141 is matched with the shape of the end of the engagement member 30; the inner diameter of the channel portion 142 is smaller than the inner diameter of the receiving portion 141, so that both the receiving portion 141 and the channel portion 142 together form an inverted concave structure that can restrict the escape of the engagement member 30.
More specifically, referring to fig. 3, the opening of the cavity 12 specifically includes a first opening 15 and a second opening 16 that are integrally communicated. The first opening 15 is communicated with the plugging cavity 13, and is used as a plugging port of the plugging cavity 13, and the shape and the size of the first opening are suitable for the tail end of the connecting piece 30 to enter for placing the connecting piece 30; the second opening 16 is connected to the channel 142 of the back-off slot 14, and is used for the inner buckle connecting piece 30 to prevent the inner buckle connecting piece from being separated, and the width of the second opening 16 is smaller than that of the first opening 15.
The lingual orthodontic accessory 10 may also be used to hang traction devices. Referring to fig. 2 to 3, preferably, two grooves 17 for hanging traction members are further formed on the periphery of the main body 11 of the lingual orthodontic accessory 10, and the number of the grooves 17 is two, and the lingual orthodontic accessory 10 is respectively formed in the mesial direction and the distal direction.
