Description

Technical Field

[0001] The present invention belongs to the technical field of oral implant equipment, and in particular relates to a plastic oral implant positioner and a positioning method thereof. Background Art

[0002] Oral dental implant technology refers to a method of restoring missing teeth that uses the lower structure implanted in the bone tissue as a basis to support and retain the upper dental restoration. It consists of two parts: the lower supporting implant and the upper dental restoration. It uses artificial materials (such as metal, ceramics, etc.) to make implants (generally similar to the shape of tooth roots), which are surgically implanted into the tissue (usually the upper and lower jaws) and obtain firm retention support from the bone tissue. The upper dental restoration is connected and supported by special devices and methods. During the oral implant surgery, oral implant locators are often required to assist the doctor in the operation.

[0003] Although there are many kinds of oral implant locators currently, there are still some problems. For example, current oral implant locators often need to cooperate with external brackets to support the locators during positioning, and the external brackets often need to be fixed in the patient's mouth in advance, and then the locator is connected to the bracket in the patient's mouth. Since the operating space inside the mouth is small, it is not convenient to operate. After the connection, if the positioning angle of the locator needs to be adjusted, the support angle of the bracket also needs to be adjusted. The operation is cumbersome, time-consuming and labor-intensive. Long-term operation will not only cause serious physical overdraft of the doctor, but also cause physical overdraft of the patient, thereby increasing the intensity and risk of the operation. Summary of the invention

The support rod 47 has a U-shaped structure, and one end of the support rod 47 is fixed to the edge of the adjusting ring 41, and the other end is located above the supporting ring 1. A plurality of clamping blocks 49 are arranged at equal intervals along the side wall of the convex ring 51. One end of the check claw 48 is rotatably connected to the end of the support rod 47 located above the supporting ring 1, and the other end abuts between two adjacent clamping blocks 49, and the check claw 48 is in sliding contact with the clamping block 49

[0043] The positioning mechanism 5 for positioning the implant drilling bit is arranged at the top of the supporting ring 1, and the positioning mechanism 5 includes a convex ring 51, a limiting seat 52, a positioning ring 53, a docking support plate 54, and an adjusting unit;

[0044] The convex ring 51 is coaxially fixed on the top of the supporting ring 1, the limiting clamping seat 52 is fixed on the top edge of the convex ring 51, the docking support plate 54 is fixed on the bottom edge of the positioning ring 53, and the end of the docking support plate 54 away from the positioning ring 53 is rotatably connected to the limiting clamping seat 52, and the positioning ring 53 is located above the convex ring 51;

[0046] It should be noted that, since the existing oral implant positioner often needs to cooperate with an external bracket to support the positioner during positioning, and the external bracket often needs to be fixed in advance inside the patient's mouth, and then the positioner is connected to the bracket in the patient's mouth. Since the operating space inside the mouth is small, it is not convenient to operate. After the connection, if the positioning angle of the positioner needs to be adjusted, the support angle of the bracket needs to be adjusted. The operation is cumbersome and time-consuming. Long-term operation will not only cause the doctor's physical overdraft, but also cause the patient's physical overdraft, thereby increasing the intensity and risk of the operation. In order to solve this problem, a support mechanism 4 and a positioning mechanism 5 are set in this scheme. Through the rotation of the adjustment ring 41 in the support mechanism 4, the driven rod 45 slides under the limiting action of the driven groove 46, thereby driving the slider 43 and the linkage rod 42 to slide as a whole, so that the docking block 44 abuts against the patient's teeth, and while the adjustment ring 41 rotates, the check claw 48 abuts against the block 49, thereby locking the adjustment ring 41 to prevent it from reversing, so that the positioner as a whole can be stably supported between two adjacent teeth of the patient;

[0047] The positioning mechanism 5 is provided so that the drill bit used for planting tapping can be guided and positioned to avoid dislocation during tapping. At the same time, the nut 56 can be threadedly linked by the rotation of the screw rod 57, so that the angle adjustment plate 55 can drive the docking support plate 54 of the positioning ring 53 to rotate on the limit clamping seat 52, so that the positioning ring 53 can be quickly adjusted to a proper angle, which is simple and efficient.

[0048] At the same time, the integrated structure of the positioning mechanism 5 and the supporting mechanism 4 effectively avoids the need to fix the bracket inside the patient's mouth in advance and then connect the locator to the bracket during use, which greatly reduces the difficulty and time of the operation and effectively maintains the physical strength of both doctors and patients.

[0049] Specifically, in this embodiment, this scheme mainly includes a supporting ring 1, a docking block 2, a limiting ring 3, a supporting mechanism 4 and a positioning mechanism 5. When in use, the positioner is first placed as a whole between two adjacent teeth of the patient. At this time, the adjusting ring 41 is rotated to make the driven rod 45 slide under the limiting action of the driven groove 46, thereby driving the slider 43 and the linkage rod 42 to slide as a whole, and the docking block 44 is driven to move through the linkage rod 42, so that the docking block 44 is abutted against the patient's teeth, and while the adjusting ring 41 is rotating, the check claw 48 abuts against the block 49, thereby locking the adjusting ring 41 to prevent it from reversing, and then rotating the screw rod 57 to enable the nut 56 to be threadedly linked, so that the angle adjustment plate 55 can drive the docking support plate 54 of the positioning ring 53 to rotate on the limiting clamping seat 52, and after adjusting the positioning ring 53 to an appropriate angle, the drill bit used for implant tapping can be guided and positioned through the positioning ring 53.

[0050] In a further preferred embodiment of the present invention, Figure 1-6 As shown, a leaf spring 410 is fixed on the side wall of one end of the support rod 47 located above the supporting ring 1 , and a portion of the leaf spring 410 slides against the side wall of the anti-return claw 48 .

[0051] In this embodiment, the anti-return claw 48 is pushed by the elastic force of the leaf spring 410 , so that the anti-return claw 48 can always abut between two adjacent clamping blocks 49 .

[0052] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the support mechanism 4 also includes an abutment plate 411 and a limit block 412, the limit block 412 is fixed on the side wall of the abutment plate 411, a slot is provided on the side of the docking block 44 away from the linkage rod 42, and the limit block 412 is slidably engaged in the slot, and the overall structure composed of the abutment plate 411 and the limit block 412 is at least provided in two groups on the docking block 44.

[0053] In this embodiment, by rotating the limit block 412 in the groove on the docking block 44, the abutment plate 411 can rotate accordingly following the surface structure of the patient's teeth, so that the positioner can be more stably supported between two adjacent teeth of the patient.

[0054] In a further preferred embodiment of the present invention, Figure 1-6 As shown, a knob 58 is coaxially fixed at the center of the screw rod 57.

[0055] In this embodiment, the knob 58 is provided to facilitate the doctor to rotate the screw 57 .
