Description

Technical Field

[0001] This utility model belongs to the field of dental implant tools, specifically, it relates to a precise implantation tool for anterior teeth with rigid positioning. Background Technology

[0002] In dental implant surgery, a cavity needs to be prepared first, and then the implant is inserted. The precision of cavity preparation and implant insertion is a crucial factor in ensuring the quality of the implant procedure.

[0003] During cavity preparation and implant placement, due to the characteristics of human dental tissue, the cavity preparation process is easily deviated towards areas with lower density due to differences in bone and tissue density. This can lead to directional deviations during cavity preparation and implant placement. Furthermore, during the implantation process, the radial gap between the guide rings of the implant guide and the screw holder can easily cause implant displacement, especially when the distance between the implant guide and the implant bone surface is large, which greatly affects the implantation quality.

[0004] To address the issue of directional deviation, current precise implant techniques require the use of a navigation system during cavity preparation and implant placement. However, navigation systems are expensive, and ordinary dentists rarely have the financial means to purchase them. Summary of the Invention

[0005] In order to overcome the problems existing in the background technology, this utility model provides a precise implantation tool with rigid limiting for anterior teeth, which can effectively avoid or reduce the problem of directional deviation during implantation, improve implantation accuracy, and ensure implantation quality. It is especially suitable for precise limiting during the implantation process of anterior teeth.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: The aforementioned anterior tooth rigid-limited precision implantation tool includes a guide plate and a staple holder; the guide plate is provided with a rigid guide ring with a length greater than 8mm, and the lower end face of the rigid guide ring is flush with the lower bottom face of the guide plate body; the staple holder is provided with a bur lock, a coding ring, a limiting post and a fixing body in sequence from top to bottom, the limiting post is a cylinder, and the outer diameter of the limiting post is tangent to the inner diameter of the rigid guide ring.

[0007] Preferably, the fixing body is provided with an elastic ring.

[0008] Preferably, the anterior tooth rigid limiting precision implantation tool also includes a drill bit and a measuring ruler. The measuring ruler includes a circular plate with a central hole and observation angle plates evenly distributed around the outer circumference of the circular plate. The outer edge of the observation angle plates is flush with the outer edge of the guide ring. The drill bit shank passes through the circular hole and is tightly connected to the measuring ruler.

[0009] Preferably, three or more observation angle plates are provided.

[0010] Preferably, the observation angle plate 32 is provided with scale lines.

[0011] Preferably, the guide plate is also provided with two observation windows, which are respectively located on the left and right sides of the rigid guide ring.

[0012] The beneficial effects of this utility model are: This invention uses a guide ring with a length greater than 8mm and a limiting post on the nail holder that fits with the guide ring. During the implantation process, the nail holder can be precisely positioned, effectively preventing directional deviation of the implant, improving the accuracy and quality of implantation.

[0013] This invention can accurately locate the planting process and effectively prevent directional deviation. Compared with the use of a navigation system, this invention can greatly reduce planting costs.

[0014] The measuring ruler of this invention can reflect the directional deviation during the hole preparation process. The drilling direction can be adjusted in a timely manner based on the deviation reflected by the measuring ruler, thereby further improving the accuracy and quality of planting.

Detailed Implementation

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0017] In the description of this utility model, unless otherwise stated, the terms "upper", "lower", "left", "right", etc., indicate the orientation or state relationship based on the orientation or state relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1

[0019] The aforementioned anterior tooth rigid-limited precision implantation tool includes a guide plate 1 and a screw holder 2.

[0020] like Figure 2 As shown, the guide plate 1 is provided with a rigid guide ring 11 with a length of 10mm. The lower end face of the rigid guide ring 11 is flush with the lower bottom face of the guide plate body. Observation windows 12 are provided on the left and right sides of the rigid guide ring 11. It should be noted that the function of the guide plate is to fix it to the healthy tooth during dental implantation and to ensure that the rigid guide ring 11 is aligned with the implant position. The structure of the guide plate body only needs to meet the requirements of fitting the implantee's tooth. After the guide plate 1 is in place, the rigid guide ring 11 is aligned with the implant position, and the lower end face of the rigid guide ring 11 is flush with the gingiva. It should be noted that the length of the rigid guide ring 11 is set to 10mm in this invention, which was obtained through a large number of simulation experiments. This length can ensure the limiting effect and meet the needs of anterior tooth implantation.

[0021] As attached Figure 1 As shown, the nail holder 2 is provided with a needle lock 25, a coding ring 22, a limiting post 23 and a fixing body 24 from top to bottom. The limiting post 23 is a cylinder and can be sleeved with the rigid guide ring 11. The outer diameter of the limiting post 23 is slightly smaller than the inner diameter of the rigid guide ring 11. Specifically, the limiting post 23 should be able to be inserted into the rigid guide ring 11 and be parallel to the rigid guide ring 11 in the circumference. For example, the outer diameter of the limiting post 23 is 0.05mm smaller than the inner diameter of the rigid guide ring 11 (tolerance 0.05mm). The needle lock 25 is used to connect with the implantation handpiece.

[0022] The fixation body 24 is provided with an elastic ring 21. The main function of the fixation body 24 is to fix the implant. The elastic ring 21 can increase the friction between the implant and the fixation body 24, so that the implant and the fixation body 24 can be firmly connected.

[0023] The staple holder 2 of this utility model is an improvement on the existing staple holder structure. The main improvement is the addition of a cylindrical limiting post 23, the outer diameter of which matches the inner diameter of the rigid guide ring 11. This limiting post 2 restricts the forward direction of the staple holder 2 during its downward movement. Specifically, the limiting action during implant placement is illustrated below: When the implant is inserted, the limiting post 23 is inserted into the rigid guide ring 11. The rigid guide ring 11 limits and prevents the limiting post 23 from deviating: even if there is a density deviation in or around the implant hole during the implant insertion process, the limiting post 23 can only move down along the inner cavity of the rigid guide ring 11 under the limiting effect of the rigid guide ring 11. This can effectively avoid or reduce directional deviation during the implant insertion process, improve implant insertion accuracy, and improve implantation quality. Example 2

[0024] During implant preparation, different drill bits (such as pilot drills and lateral drills) are typically used. To ensure accuracy in the direction of the preparation, a full-length guide plate or a partial guide plate is usually used in conjunction with the drill bit. A full-length guide plate provides precise spatial guidance throughout the entire implantation process (from the initial positioning drill to the final implant placement). Its parameters are fixed, making operation rigid and unadjustable, and it is also more expensive. A partial guide plate guides the initial positioning drill for implant placement, allowing the surgeon to perform subsequent staged preparation and implant placement with their "free hand," offering greater flexibility. However, when using a partial guide plate, especially during preparation, sufficient radial clearance is required between the drill shank and the rigid guide ring 12 to allow the drill bit to rotate under the movement of the implant handpiece. This results in ineffective drill bit positioning, making it easy for the drill bit to deviate in direction during drilling, leading to deviations in the preparation direction.

[0025] To overcome this problem, this embodiment, based on embodiment 1, includes two guide plates 1: an implantation guide plate (a conventional half-section guide plate for preparing the cavities) and an implantation guide plate. The implantation and implantation guide plates have the same structure, differing only in the length and inner diameter of their rigid guide rings 11. The rigid guide ring 11 of the implantation guide plate has an inner diameter of 3mm and a length of 5mm, while the rigid guide ring of the implantation guide plate has an inner diameter of 5mm and a length of 10mm. The implantation process using these two guide plates is as follows: Demonstration of the hole preparation process: The demonstration will take the use of an implantation guide (a conventional half-path guide) and implantation tools to implant a 3.5mm diameter implant as an example.

[0026] The implantation guide plate is used to prepare the hole step by step. Specifically, start with the finest drill bit (e.g., 2.0mm drill bit), then gradually replace it with 2.4mm drill bit and 2.8mm drill bit, and then use the corresponding drill bit in the implantation tool box to prepare the hole to the required diameter. This utility model uses a guide plate with a rigid guide ring 11 and an inner diameter of 3mm to prepare the hole. The gap between the rigid guide ring 11 and the drill bit shank is reduced, which effectively reduces the directional deviation during the hole preparation process.

[0027] After the hole preparation is completed, the guide plate is replaced with an implantation guide plate, and the implant is installed on the fixation body 24 of the nail holder. Under the limiting action of the rigid guide ring 11, the deviation of the implantation direction is effectively avoided.

[0028] This embodiment uses two guide plates, one for preparing the planting hole and the other for implanting the implant, which effectively improves the precision control of the planting process. Example 3

[0029] This embodiment adds a measuring ruler 3 to embodiments 1 and 2. This embodiment mainly describes the structure and usage of the measuring ruler 3.

[0030] As attached Figure 3 and 4 As shown, the measuring ruler 3 includes a circular plate with a central hole 31 and observation angle plates 32 evenly distributed around the outer circumference of the circular plate. The observation angle plates 32 are triangular with rounded corners at their outermost ends. The observation angle plates 32 are all the same size, and four of them are provided.

[0031] The following is an explanation of how to use the correction plate, taking the hole preparation process as an example: Place the measuring ruler 3 on the drill shank of the drill bit 4 and observe the four observation angle plates 32. If the arc angle of the four observation angle plates 32 exceeds the outer edge of the rigid guide ring 11, it means that the hole axis is biased towards the side where the observation angle plates exceed. In the next hole preparation step, adjust it to the opposite side (for example, taking the implantation of a 3.5mm diameter implant in Example 2 as an example: when preparing the hole with a 2.4mm drill bit, if there is a deviation according to the position of the observation angle plates, when continuing to prepare the hole with a 2.8mm drill bit, adjust the hole preparation direction to the opposite side).

[0032] As a preferred option, a scale line is provided on the outer edge of the observation angle plate 32. The degree of offset can be determined according to the scale line, so as to determine the next correction adjustment range.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
