[0008] By adopting the above technical solution, an adjustment component is set on the guide sleeve. When in use, the curvature of the guide sleeve is first adjusted by the adjustment component to make the guide sleeve adapt to the patient's alveolar bone, and then the guide sleeve is worn on the patient's teeth, so that the guide sleeve can adapt to different alveolar bone shapes, which can effectively reduce the cost of use; finally, a drill is used to drill a hole from the positioning hole to facilitate the installation of the implant.

[0009] Optionally, the adjustment assembly includes a screw, a sleeve and an adjusting nut, the ends of the screw and the sleeve are respectively hinged and fixed on both sides of the inner wall of the guide plate sleeve, the screw is slidably inserted in the sleeve, and the adjusting nut is coaxially rotatably installed on one end of the sleeve close to the screw, and the adjusting nut is threadedly connected to the screw.

[0010] By adopting the above technical solution, a screw rod, a sleeve and an adjusting nut are provided. When in use, the depth of the screw rod inserted into the sleeve can be controlled by turning the adjusting nut, thereby adjusting the distance between the two ends of the guide sleeve, thereby achieving the purpose of adjusting the curvature of the guide sleeve, which is convenient to use.

[0011] Optionally, the screw rod, the sleeve and the adjusting nut are arranged in multiple groups on the inner side wall of the guide plate sleeve.

[0012] By adopting the above technical solution and setting multiple groups, the adjustment accuracy of the guide plate sleeve can be effectively improved and the adaptability can be improved.

[0013] Optionally, a tightening bolt is screwed onto the side wall of the tooth groove on the guide plate sleeve.

[0014] By adopting the above technical solution, after the guide plate sleeve is worn, the tightening bolt is screwed to tighten the tightening bolt against the tooth body, thereby preventing the guide plate sleeve from being displaced during use.

[0015] Optionally, a wear-resistant sleeve is coaxially fixed on the guide plate sleeve in the positioning hole.

[0016] By adopting the above technical solution and providing a wear-resistant sleeve, it is possible to prevent the guide plate sleeve from being damaged during the drilling process of the drill bit.

[0017] Optionally, the wear-resistant sleeve is configured as an alloy steel sleeve.

[0018] Optionally, a fixing screw for fixing to the original implant is installed on the guide sleeve at a position corresponding to the original implant.

[0019] By adopting the above technical solution, if the patient has had dentures implanted before, the original base can be removed, and then the fixing screws can be screwed on the position where the implant was originally installed. The guide sleeve can be fixed through the original implant, which is convenient for use.

[0020] Optionally, the fixing screw is set to simulate the shape of the abutment.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. By setting an adjustment component on the guide sleeve, when using it, first adjust the curvature of the guide sleeve through the adjustment component to make the guide sleeve fit the patient's alveolar bone, and then wear the guide sleeve on the patient's teeth, so that the guide sleeve can adapt to different alveolar bone shapes, which can effectively reduce the cost of use; finally, drill a hole through the positioning hole to facilitate the installation of the implant;

[0023] 2. By setting the screw, sleeve and adjusting nut, when in use, the depth of the screw inserted into the sleeve can be controlled by twisting the adjusting nut, thereby adjusting the distance between the two ends of the guide sleeve, thereby achieving the purpose of adjusting the curvature of the guide sleeve, which is convenient for use.

[0027] The following is combined with Figure 1-2 This application is described in further detail.

[0028] The present application embodiment discloses a support guide plate, referring to Figure 1 and Figure 2 The invention comprises a C-shaped guide plate sleeve 1, and a tooth groove 11 for sleeved on teeth is provided on one side of the guide plate sleeve 1. When in use, the guide plate sleeve 1 can be directly worn on the patient's teeth. An adjustment component 2 for adjusting the curvature of the guide plate sleeve 1 is provided on the guide plate sleeve 1. When in use, the curvature of the guide plate sleeve 1 can be adjusted according to the shape of the alveolar bone, so that the patient can wear it conveniently.

[0029] The adjustment assembly 2 includes a screw 21, a sleeve 22 and an adjustment nut 23. The ends of the screw 21 and the sleeve 22 are hingedly mounted on the inner walls of the guide plate sleeve 1 on both sides, and the rotation direction of the screw 21 and the sleeve 22 is perpendicular to the plane where the guide plate sleeve 1 as a whole is located. The screw 21 is inserted into the sleeve 22, and the adjustment nut 23 is rotatably mounted on one end of the sleeve 22 close to the screw 21, and the adjustment nut 23 is screwed on the screw 21. There are multiple groups of screws 21, sleeves 22 and adjustment nuts 23 distributed on the guide plate sleeve 1. When in use, the depth of the screw 21 inserted into the sleeve 22 can be controlled by twisting the adjustment nut 23, thereby pulling the two sides of the guide plate sleeve 1 closer to or away from each other, so as to achieve the purpose of adjusting the curvature of the guide plate sleeve 1.

[0030] A tightening bolt 12 is screwed on the guide sleeve 1, and the tightening bolt 12 is located on the side wall of the tooth groove 11. After the guide sleeve 1 is worn, the tightening bolt 12 is screwed to make the tightening bolt 12 press against the tooth, thereby locking the guide sleeve 1. If the patient has implanted dentures before, a fixing screw 13 can be installed on the guide sleeve 1 at the position where the implant was originally installed. The fixing screw 13 is similar to the abutment structure. The fixing screw 13 is tightened and fixed on the previously implanted implant to fix the guide sleeve 1.

[0031] A positioning hole 14 is provided on the bottom of the tooth groove 11 corresponding to the position of the artificial tooth to be implanted, and a wear-resistant sleeve 15 made of alloy steel is embedded and fixed in the positioning hole 14. After the guide plate sleeve 1 is fixed, drilling can be performed from the positioning hole 14 to improve the drilling accuracy, and the wear-resistant sleeve 15 can prevent the drill bit from damaging the wear-resistant sleeve 15.

[0032] The implementation principle of a support guide plate disclosed in the embodiment of the present application is: by setting an adjustment component 2 on the guide plate sleeve 1, when in use, according to the shape of the patient's alveolar bone, the adjustment nut 23 is turned to control the depth of the screw 21 inserted into the sleeve 22, thereby adjusting the distance between the two ends of the guide plate sleeve 1, so as to achieve the purpose of adjusting the curvature of the guide plate sleeve 1, so that the guide plate sleeve 1 is adapted to the shape of the patient's alveolar bone, improve the applicability of the guide plate sleeve 1, and reduce the cost of denture implantation. The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore: all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
