[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] Please refer to Figures 1 to 4The present application provides a technical solution: a rod-type precision accessory suitable for missing teeth at both ends, comprising a connecting plate main body 1 and a denture main body 2, wherein a connecting component 500 for positioning the denture main body 2 is installed between the connecting plate main body 1 and the opposite side of the denture main body 2; through the coordination between the denture main body 2 on the outside of the connecting plate main body 1 and the connecting component 500, it can be conveniently positioned and also relatively comfortable to remove, without adding too much additional structure, so that it can achieve the desired effect through simple structural coordination, thereby allowing the wearer to use it stably while also being able to remove and clean it conveniently and comfortably, thereby further improving the practicality of the rod-type precision accessory.

[0032] In this embodiment, the connecting assembly 500 is a structure for connecting the denture body 2 and the connecting plate body 1 .

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, the connecting component 500 includes a fixing part 501 fixed to the outside of the denture body 2, a connecting piece 502 fixed to the fixing part 501 on the side close to the connecting plate body 1, a limiting column 503 fixed to the side of the connecting piece 502 away from the denture body 2, a limiting groove 504 opened on the top of the connecting plate body 1, a connecting groove 505 opened on the side of the connecting plate body 1 close to the denture body 2, a spring piece 506 fixed to the right side of the connecting plate body 1, a snap-in protrusion 507 fixed to the front side of the spring piece 506, and a snap-in groove 508 opened on the back side of the limiting column 503.

[0034] It should be noted that the limiting groove 504 is for the limiting column 503 to be inserted and slid, the interior of the connecting groove 505 is connected to the interior of the limiting groove 504, the top of the connecting groove 505 is open, and the connecting groove 505 is for the connecting piece 502 to be inserted and slid, so that the limiting column 503 and the connecting piece 502 can be moved to the inner side of the limiting groove 504 and the connecting groove 505 respectively.

[0035] At the same time, an open groove connected to the limiting groove 504 and the connecting groove 505 is opened on the back side of the connecting plate body 1. The top and right side of the opening groove are both open, and the spring piece 506 is fixed on the inner side of the opening groove. The spring piece 506 is arc-shaped, so that the spring piece 506 can be normally pressed by the user's fingers.

[0036] In addition, the outer side of the snap-in protrusion 507 is arc-shaped, and the snap-in protrusion 507 can be inserted into the inner side of the snap-in groove 508, so that when pressing down, the snap-in protrusion 507 can directly drive the spring piece 506 to deform, and then it can be inserted into the inner side of the snap-in groove 508. When it needs to be removed, the spring piece 506 can be slightly pushed so that the snap-in protrusion 507 is appropriately away from the snap-in groove 508, and it can be easily taken out.

[0037] As Figure 1 shown, it should also be noted that a fixing piece 3 is fixed on the side of the connecting plate body 1 away from the denture body 2. The bottom of the denture body 2 abuts against a denture base 401. A positioning protrusion 402 is fixed on the top of the denture base 401. A plugging groove for the positioning protrusion 402 to be plugged into is opened at the bottom of the denture body 2, so that the denture body 2 can be positioned through the cooperation between the positioning protrusion 402 and the plugging groove. Specifically, the fixing piece 3 is fixed on the outside of an adjacent tooth, and the denture base 401 is connected to the position where the tooth is missing and is connected and fixed through a transplantation operation to simulate the tooth root and facilitate the installation of the denture body 2. Among them, the structures used in this bar-type precision attachment need to be materials that can be applied to denture installation and meet medical requirements, such as resin materials, nickel-chromium alloy materials, cobalt-chromium alloy materials, titanium alloy materials, and pure titanium materials.

[0038] The working principle of the above embodiment is as follows:

[0039] During installation, directly plug the limit post 503 into the inside of the limit groove 504, and make the denture body 2 abut against the top of the denture base 401 and limit it through the positioning protrusion 402. Press the denture body 2 to make the clamping protrusion 507 be clamped and limited inside the clamping groove 508, and the limiting and fixing of the denture body 2 can be realized. When it needs to be removed, buckle the elastic piece 506 so that the clamping protrusion 507 can be partially or completely removed from the inside of the clamping groove 508, and then the denture body 2 can be pulled upward to make it away from the denture base 401, and the removal work can be completed. The whole process is very convenient and will not cause too much discomfort.

[0040] Compared with the prior art, this bar-type precision attachment applicable to tooth loss at both ends can facilitate positioning and be removed more comfortably through the cooperation between the denture body 2 outside the connecting plate body 1 and the connecting component 500, and will not add too many additional structures, enabling it to achieve the required effect through simple structural cooperation. Furthermore, the wearer can use it stably and can also remove and clean it conveniently and comfortably, thereby further improving the practicality of the bar-type precision attachment and solving the drawback that the existing precision attachments are prone to pulling the gums during the removal of the denture, resulting in a decrease in overall comfort.
