[0028] like Figure 1 to Figure 2 As shown, a high-precision implantation guide comprises an implantation guide body 1, a spring clip assembly 2, and a mounting hole portion 3 provided on the implantation guide body 1 and used for implanting dentures; the implantation guide body 1 is provided with at least two spring clip assemblies 2 for clamping and fitting the labial side of the patient's teeth. The high-precision implantation guide achieves accurate positioning of the implantation site and direction of the implanted denture in the mounting hole portion 3 by adding at least two spring clip assemblies 2 to the implantation guide body 1 for clamping and fitting the labial side of the patient's teeth. The guide has good stability, does not require a metal mounting ring to be placed in the mounting hole portion 3, makes clinical operation more convenient, and improves the accuracy of the implantation site and direction. At the same time, the high-precision implantation guide has a simple overall structure and is easy to install. It does not require lateral nail fixation during installation, and causes less trauma to the patient.

[0029] Preferably, the implant guide body 1 is a semi-wrapped structure; the implant guide body 1 includes a lingual base surface 11 provided on the lingual side of the tooth, a mandibular base surface 12 fitted with the top surface of the tooth, and a labial edge surface 13 provided on the labial side of the tooth; one side of the mandibular base surface 12 is connected to the lingual base surface 11; the other side is connected to the labial edge surface 13, so that the implant guide body 1 is an inverted and reverse "L"-shaped semi-wrapped structure. The lingual base surface 11 and the mandibular base surface 12 are individually designed according to the tooth morphology, which are more fitted and more accurately positioned. The lowermost end of the labial edge surface 13 is slightly higher than the lowermost end of the mounting hole portion 3; the spring buckle assembly 2 is provided on the mandibular base surface 12 and the labial edge surface 13. By setting the implant guide body 1 as a semi-wrapped structure, the lowest end position of the labial edge surface 13 is made slightly higher than the lowest end position of the mounting hole portion 3, and the spring clip assembly 2 is set on the jaw base surface 12 and the labial edge surface 13, and the spring clip assembly 2 is combined with the implant guide body 1 to be pressed and fitted to the labial side of the patient's teeth, which makes it convenient to observe the fit between the implant guide body 1 and the teeth, avoids large errors during implantation, and helps to improve the accuracy of the implant site and direction.

[0030] The spring clip assembly 2 includes a first spring plate 21, a second spring plate 22, a third spring plate 23, a first clip 24, a second clip 25, a spring 26 and a support rod 27; the first spring plate 21 is arranged on the jaw base surface 12; the first clip 24 is arranged on the first spring plate 21; the second spring plate 22 is arranged on the lip side edge surface 13 and connected to the first spring plate 21; the connection between the first spring plate 21 and the second spring plate 22 is provided with an inclined slot 28; the third spring plate 23 is rotatable The third elastic plate 23 is movably connected to the lower end of the second elastic plate 22 and can swing up and down relative to the second elastic plate 22; the lower end of the lip side edge surface 13 is provided with springs 26 located on both sides of the lower end of the second elastic plate 22 and is connected to the upper end of the third elastic plate 23; the second buckle 25 is arranged at the lower end of the third elastic plate 23; one end of the supporting pressure rod 27 is clamped and fixed with the first buckle 24, and the other end passes through the inclined slot 28 and is clamped with the second buckle 25, so that the third elastic plate 23 is clamped and fits the lip side of the patient's teeth. The spring buckle assembly 2 is formed by the first spring plate pressing plate 21, the second spring plate pressing plate 22, the third spring plate pressing plate 23, the first clip 24, the second clip 25, the spring 26 and the supporting pressure rod 27. After the implant guide body 1 is installed, the third spring plate pressing plate 23 is rotated to swing up and down relative to the second spring plate pressing plate 22 to press and fit the patient's tooth lip side. The third spring plate pressing plate 23 is a customized plate body made of different lengths and curvatures according to the shapes of different patients' teeth. It is easy to press and fit with the patient's tooth lip side and has good comfort. Then, the supporting pressure rod 27 acts with the first clip 24, the second clip 25 and the inclined slot 28, and the two ends of the supporting pressure rod 27 are clamped and fastened with the first clip 24 and the second clip 25. The inclined slot 28 stabilizes, positions and supports the support rod 27. The third spring plate 23 is better pressed and fit on the lip side of the patient's teeth. It is combined with the implant guide body 1 to facilitate observation of the fit between the implant guide body 1 and the teeth, avoid large errors during implantation, and help improve the accuracy of the implant site and direction. At the same time, it is convenient for doctors to open and close the implant guide body 1 when installing it. One end of the support rod can be clamped on the implant guide body 1 (i.e., the first clamp 24 is clamped), and of course it can also be fixed on the implant guide body 1 (fixedly connected with the first clamp 24), and the other end is used in conjunction with the second clamp 25 to achieve the purpose of clamping and fitting the lip side of the patient's teeth, making clinical operation more convenient. By using the first spring plate 21, the second spring plate 22, and the third spring plate 23 as the plate bodies, these plate bodies have good elasticity, are easy to install, and are easy to fit better with the lip side of the patient's teeth, so that patients can use the high-precision implant guide more comfortably.

[0031] Specifically, the support rod 27 has a bent portion 271 that fits with the inclined surface slot 28 when the other end of the support rod 27 passes through the inclined surface slot 28. By providing the support rod 27 with the bent portion 271, when the support rod 27 passes through the inclined surface slot 28, the inclined surface slot 28 supports and positions the support rod 27, so that the third elastic sheet can be better pressed and fit the lip side of the patient's teeth.

By providing the first positioning groove 121 and the second positioning groove 131, it is convenient to install the first spring plate pressing plate 21 and the second spring plate pressing plate 22 in the first positioning groove 121 and the second positioning groove 131, which plays a good role in positioning and stabilizing the first spring plate pressing plate 21 and the second spring plate pressing plate 22, thereby facilitating the installation and fixation of the spring buckle assembly 2, and having good stability.

[0033] In order to improve the patient's comfort, the high-precision implant guide is installed in the patient's mouth for a more beautiful overall visual appearance. The upper surface of the first spring plate pressure plate 21 is level with the jaw base surface 12 ; the front surface of the second spring plate pressure plate 22 is level with the labial edge surface 13 .

[0034] In this specific embodiment, the first spring plate 21 is arranged in the first positioning groove 121 by spot welding; the second spring plate 22 is arranged in the second positioning groove 131 by spot welding. The first spring plate 21 and the second spring plate 22 are respectively installed in the first positioning groove 121 and the second positioning groove 131 by spot welding, so that the spring buckle assembly 2 is more firmly positioned on the implantation guide body 1. In order to effectively increase the friction force and prevent the implantation guide body 1 from sliding during the doctor's drilling process, a layer of food-grade rubber tube 4 is wrapped on the lower end of the third spring plate 23 and the second buckle 25.

[0035] In this specific embodiment, in order to enhance the installation stability of the high-precision implant guide, two spring buckle assemblies 2 are provided on the implant guide body 1; the mounting hole portion 3 is located between the two spring buckle assemblies 2. By providing two spring buckle assemblies 2 at the left and right ends of the mounting hole portion 3, the implantation site and direction of the implanted denture in the mounting hole portion 3 can be accurately positioned, with good stability, and the accuracy of the implantation site and direction can be improved.

[0036] In this specific embodiment, the implant guide body 1 is formed by metal 3D printing, which is convenient for rapid customization and high automation. The metal material used is cobalt-chromium alloy, nickel-chromium alloy, etc., which are low-priced and have excellent toughness.

[0037] In summary, the embodiment of the present invention provides a high-precision implantation guide, wherein the high-precision implantation guide is combined by adding at least two spring clip components 2 on the implantation guide body 1 to be used for clamping and fitting the patient's tooth lip side, so as to achieve accurate positioning of the implantation site and direction of the implanted denture in the mounting hole 3, with good stability, no need to place a metal mounting ring in the mounting hole 3, more convenient clinical operation, and improved accuracy of the implantation site and direction. At the same time, the high-precision implantation guide has a simple overall structure, is easy to install, does not require lateral nail fixation during installation, and causes little trauma to the patient.

[0038] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
