Description

Technical Field

[0001] The invention relates to a detachable guiding auxiliary implantation guide plate, belonging to the technical field of oral medicine. Background Art

[0002] Oral implantology is a new independent branch of oral science, which involves many disciplines in oral science, including oral and maxillofacial surgery, oral prosthodontics, periodontology, oral imaging and dental materials.

[0003] At present, some people's teeth are defective or missing due to caries, trauma, inflammation, tumors and other reasons. When teeth are defective, they can be repaired by various filling materials, and when teeth are missing, they can be repaired by implanting or dentures. When the missing teeth are repaired by implanting, the implantation position, direction and depth of the dental implant are the key factors affecting the success of the operation. Incorrect positioning and deviation in direction during implantation can easily lead to bone fractures in the implant area, perforation of the alveolar bone side wall, root nerve damage and other phenomena, which bring great difficulties to the subsequent repair of the upper structure. For this reason, some doctors use positioning guide templates to assist in dental implant surgery. Through the correct positioning and precise guidance of the implant shell guide template, the failure of the implant repair function due to inaccurate implantation position and direction is avoided. The traditional method of making the shell template is to manually make a transparent self-curing plastic or thermosetting plastic template on a plaster model. Its disadvantages are insufficient precision and poor visual effect. Surgical templates pressed by air laminating machines are low-cost and simple to make, but their positioning and guiding accuracy is not high, and it is difficult to obtain the ideal position and direction. They are mainly used to guide the implantation of a single or two adjacent implants or surgeries with less stringent implant position requirements. With the widespread application of CT images, many guide templates modified on the basis of CT templates have been derived. This method uses CT tomography technology to scan the upper and lower jaws of patients with edentulous or missing teeth wearing radiopaque marker templates. The images and data obtained are used for auxiliary design and three-dimensional reconstruction through a variety of computer-aided software, and finally the shell template is obtained through rapid prototyping technology.

[0004] Currently, the positioning of implant guides is inaccurate, and the implant direction is prone to change during the implant process, resulting in poor implant results and affecting the patient's post-implantation treatment outcome. The patient's dentition condition cannot be observed during the implant process, and the field of vision will be interfered with by the implant guide. The implant cannot ensure the implantation angle during the implant process, and when the implant angle deviates, the post-treatment outcome will be affected to a certain extent, and in severe cases, the patient's dentition will be damaged. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a detachable guiding auxiliary planting guide plate, which solves the problems of inaccurate positioning of the planting guide plate and the planting guide plate affecting the field of vision.

[0006] The technical problem to be solved by the present invention is achieved by adopting the following technical solution: a detachable guiding auxiliary planting guide plate, comprising a supporting guide plate and an extension frame, wherein the extension frame is arranged on one side of the supporting guide plate.

[0032] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0033] Example 1

[0034] like Figure 1-Figure 5 As shown,

[0035] A detachable guiding auxiliary planting guide plate comprises a supporting guide plate 1 and an extension frame 11. The supporting guide plate 1 and the extension frame 11 are attached to each other, and the extension frame 11 is arranged on one side of the supporting guide plate 1. The supporting guide plate 1 and the extension frame 11 are an integrated structure.

[0036] After the molars on one side of the patient are lost due to various reasons, a tooth is implanted at the position of the missing tooth, and the implantation tool needs to be guided during the implantation process. The support guide plate 1 is fixed to the patient's intact teeth. The structure of the support guide plate 1 is consistent with the patient's dentition structure. The support guide plate 1 can be set in the patient's dentition to wrap the patient's incisors and part of the intact molars. The extension frame 11 is set on one side of the missing molar. The extension frame 11 is connected to the support guide plate 1 to form an integrated structure. The extension frame 11 is set at the patient's missing teeth. The end of the extension frame 11 away from the support guide plate 1 is set at the top of the patient's alveolar bone. The main body of the extension frame 11 is set on the front side of the patient's dentition and does not interfere with the area of ​​the implanted dentition.

[0037] A mounting groove 12 is provided at the top of the support guide plate 1 near the extension frame 11, and a mounting groove 12 is also provided at the top of the extension frame 11 away from the support guide plate 11. The mounting grooves 12 are perpendicular to the support guide plate 1, and in this embodiment, the mounting grooves 12 are in the form of quadrangular prisms.

[0038] The detachable connecting rod 2 is fixed to the support guide plate 11 through the mounting groove 12, referring to Figure 1 , Figure 3 Both ends of the detachable connecting rod 2 are provided with mounting blocks that match the mounting groove 12. The structure of the mounting block is the same as that of the mounting groove 12. The mounting block can be fixed in the mounting groove 12 to ensure that the detachable connecting rod 2 does not move when it is fixed on the support guide plate 1.

[0039] The main body of the detachable connecting rod 2 is provided with a plurality of planting holes 21, and the connecting rod is fixed at both ends of the planting holes 21. The end of the connecting rod not fixed at the planting hole 21 is arranged on the top of the mounting block, extends upward for a distance, then extends to the side, and then extends downward to connect with the planting hole 21.

[0040] In this embodiment, there are two implantation holes 21. The implantation holes 21 are located on the patient's dentition where the patient needs to install the positioning pins. When installing the positioning pins, the implantation holes on the detachable connecting rod 2 guide the installation of the positioning pins to prevent the positioning pins from deviating during the installation process.

[0041] An implant axial guide rod 13 is provided on the side of the extension frame 11 close to the patient's buccal surface. Figure 1 , Figure 4 The number of implant axial guiding rods 13 is the same as the number of implant holes 21. The implant axial guiding rods 13 can guide the implantation direction of the implant.

[0042] During the installation of the support guide plate 1, it is necessary to observe the position of the support guide plate 1 on the patient's dentition. A base positioning observation window is provided in the middle of the support guide plate 1. The base positioning observation window is a groove provided on the support guide plate 1. The crown parts of the patient's central incisor and lateral incisor can be exposed in the field of vision through the base positioning observation window, thereby ensuring that the support guide plate 1 does not shift during the process of being fixed to the patient's dentition.

[0043] The support guide plate 1 is provided with a cross-sectional observation window at the edge of one side away from the extension frame 11. In the present embodiment, the support guide plate 1 as a whole is consistent with the model of the patient's dentition. The support guide plate 1 is provided with a cross-sectional observation window at the edge away from the extension frame 11. In the present embodiment, the cross-sectional observation window is provided in front of the first molar and can observe the distal cusp. The cross-sectional observation window is square and is vertically provided at the edge of the support guide plate 1, which can ensure that the support guide plate 1 does not block the patient's first molar, and at the same time can ensure the stability of the support guide plate 1, and avoid the support guide plate 1 from being offset due to force during the implantation process.

[0044] Making a removable guiding auxiliary implant guide includes the following steps:

[0045] 1. Perform a CT scan on the patient's jaw to obtain information about the patient's jaw.

[0046] 2. Use an intraoral scanner to obtain the patient's dentition and soft tissue data, and use this data and the patient's jaw information obtained by CT scanning to combine them to form three-dimensional digital data of the jaw and teeth.

[0047] 3. The support guide plate 1 and implant axial guide rod 13 designed and generated based on the three-dimensional digital data.

[0048] 4. Make a model of the three-dimensional digital data of the jaw and teeth, make the support guide plate 1, the implant axial guide rod 13, and the detachable connecting rod 2.

[0049] The structure of the detachable connecting rod 2 is arranged according to the direction of the implant axial guiding rod 13 , and the guiding direction of the implant hole 21 on the detachable connecting rod 2 is the guiding direction of the implant axial guiding rod 13 .

[0050] The implantation position is simulated on a model of the patient's jaw and teeth three-dimensional digital data to ensure that the positioning and guiding functions of the detachable connecting rod 2 meet the expected effects.

[0051] When using the removable implant guide, refer to Figure 5 During the implantation process, the implant is guided by the implantation hole 21 on the detachable connecting rod 2. During the implant installation process, the detachable connecting rod 2 can provide a fixed point for implantation. It cannot be guaranteed that the doctor can install the implant on the patient's dentition at a preset angle from the implantation hole 21 on the detachable connecting rod 2 every time. Therefore, an implant axial guide rod 13 is provided on the support guide 1. The implant axial guide rod 13 can guide the doctor on the angle of the implant when installing the implant. It is prevented that the implant passes through the implantation hole 21 on the detachable connecting rod 2 after implantation, but the implantation angle is incorrect, which affects the implantation effect.

[0052] During the implantation process, the support guide plate 1 is fixed to the patient's dentition, and the detachable connecting rod 2 can be removed to expose the patient's implanted area, ensuring that the doctor can observe the patient's state within the range of the positioning pins to be implanted. After the detachable connecting rod 2 is installed, the implant is guided by the implantation hole 21 on the detachable connecting rod 2 to ensure that the position of the implant does not change.

[0053] like Figure 5 As shown, the effect of the implant after implantation not only needs to ensure the spacing between the implants and the position on the patient's dentition, but also needs to ensure the angle of the implant implanted in the patient. The detachable connecting rod 2 can ensure that the position of the implant on the patient remains unchanged; the implant axial guide rod 13 can provide guidance for the doctor during the implant implantation process to ensure that the implant is implanted at the set angle.

[0054] The basic principles, main features and advantages of the present invention are shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
