Description

Technical Field

[0001] This utility model relates to the field of restorative framework technology, and in particular to a dental restorative framework. Background Technology

[0002] Dental restoration generally refers to the process of repairing damaged, missing, or functionally abnormal teeth using artificial materials or techniques. Currently, common dental restoration methods include resin restorations and dental implants.

[0003] Resin restoration is mainly used when the tooth damage is relatively minor, and is often used to repair front teeth. Currently, when using resin restoration, an L-shaped restorative frame is usually needed. By coordinating the restorative frame with the damaged tooth, the cavity to be filled is revealed. Then, resin is filled into the cavity, the resin is cured, the restorative frame is removed, and the above process is repeated on the other side of the tooth to complete the tooth restoration.

[0004] However, during the resin filling process, since the L-shaped piece only has two continuous edges, it is difficult to constrain the resin, which can easily lead to excessive resin filling. This not only wastes the resin but also increases the workload of subsequent sanding. Utility Model Content

[0005] The main purpose of this invention is to provide a dental restoration frame that addresses the problem in related technologies where excessive open areas in the restoration frame lead to overfilling with resin.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A dental restoration frame includes a frame body with a "U"-shaped structure; the frame body has a fitting plate, which is slidably connected to the frame body, and an elastic element is provided between the fitting plate and the frame body to fit itself to the patient's tooth.

[0008] Furthermore, the bonding plate is provided with a number of limiting posts, the elastic element is provided with a number of elastic elements, and the frame body is provided with a number of limiting holes for mutual hole-shaft cooperation with each limiting post, and each elastic element is sleeved with a limiting post in a corresponding manner.

[0009] Furthermore, the bonding plate is provided with several rotating frames, and one end of each limiting post close to the rotating frame is rotatably connected to each rotating frame; the rotation axis between each limiting post and the rotating frame is perpendicular to the horizontal plane.

[0010] Furthermore, each of the limiting posts has a rotating body at one end near the bonding plate, and the rotating body has a rotating shaft for rotating connection with the rotating frame.

[0011] Furthermore, each of the rotating frames includes two rotating plates, and each rotating plate is provided with a rotating hole for the rotatable connection of the limiting post; the rotating plates are symmetrically and evenly distributed with the limiting post as the center.

[0012] Furthermore, the frame body includes a first horizontal plate, a second horizontal plate, and a connecting vertical plate, and the length of the bonding plate is longer than the lengths of the first horizontal plate and the second horizontal plate.

[0013] Furthermore, each of the limiting posts is provided with a limiting plate at the end away from the bonding plate to limit its own movement distance.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] This utility model's technical solution adopts a "U"-shaped structure for the frame body, which, without affecting the interlocking fit between the frame body and the tooth gap, creates a "groove" structure in the patient's tooth, expanding the constraint surface of the frame body on the resin and making it less likely to fill with excessive resin.

[0016] Meanwhile, the frame body is provided with a bonding plate, which is slidably connected to the frame body. An elastic element is provided between the bonding plate and the frame body to allow it to conform to the patient's tooth. When the opening of the frame body (groove structure) is larger than the tooth thickness, the bonding plate located in the frame body can adhere to the tooth with the help of the elastic force of the elastic element. The missing tooth (the tooth to be repaired), one side of the frame body, and the bonding plate cooperate to form a resin repair cavity, effectively ensuring that this invention can maintain a good fit with the patient's tooth to be repaired, effectively avoiding interference from individual patient differences on the practicality of this invention, and effectively improving the versatility of this invention.

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] Example 1

[0028] like Figure 1 As shown, this embodiment proposes a dental restoration frame, which mainly includes a frame body 1. The frame body 1 has a "U" shaped structure. Correspondingly, the frame body 1 mainly includes a first horizontal plate 12, a second horizontal plate 13, and a connecting vertical plate 14. The first horizontal plate 12 and the second horizontal plate 13 are located at the two ends of the connecting vertical plate 14, and the three are integrally formed to ensure the stability and strength of the overall structure of the frame body 1.

[0029] Simultaneously, when installing this embodiment in the patient's oral cavity, it should be connected by the interlocking of the connecting vertical plate 14 with the gap between the patient's teeth. In this way, the frame body 1 can form a "groove" structure in the patient's teeth, expanding the constraint surface of the frame body 1 on the resin, thereby making it less likely to fill with too much resin, reducing resin waste, and reducing the amount of subsequent polishing work on the resin repair.

[0030] To better adapt this embodiment to the patient's missing teeth, the frame body 1 is provided with a fitting plate 2. The fitting plate 2 is slidably connected to the frame body 1, and an elastic element 3 is provided between the fitting plate 2 and the frame body 1 to fit itself to the patient's teeth. The elastic element 3 is located on the second horizontal plate 13. Thus, after the frame body 1 is inserted into the patient's oral cavity, it is only necessary to ensure that the first horizontal plate 12 abuts against the patient's missing teeth. The fitting plate 2 can then abut against the end of the missing teeth away from the first horizontal plate 12 under the action of the elastic element 3. This means that the repair cavity provided in this embodiment is actually formed by the mutual cooperation of the first horizontal plate 12 and the fitting plate 2. Since the width of the repair cavity is adjustable, this embodiment can adapt to missing teeth of various thicknesses, effectively avoiding the interference of individual patient differences on the practicality of this embodiment, and effectively improving the versatility of this embodiment.

[0031] Meanwhile, to facilitate adjustment of the spacing between the bonding plate 2 and the first horizontal plate 12, such as Figure 2 As shown, the length of the bonding plate 2 is longer than the lengths of the first horizontal plate 12 and the second horizontal plate 13. That is, the bonding plate 2 can protrude from the "groove" structure formed by the frame body 1, so that when the staff uses oral medical tools such as oral forceps and oral clamps to install this embodiment, they can directly clamp the second horizontal plate 13 and the bonding plate 2, so that the bonding plate 2 can be away from the first horizontal plate 12, effectively avoiding the presence of the bonding plate 2 from affecting the installation of this embodiment in the patient's mouth.

[0032] like Figure 3 As shown, the bonding plate 2 is provided with several limiting posts 4, each of which is fixedly connected to the bonding plate 2. Several elastic elements 3 are provided, and the frame body 1 is provided with several limiting holes 11 for mutual engagement with each limiting post 4. Each elastic element 3 is sleeved onto a corresponding limiting post 4. In this embodiment, the elastic element 3 is preferably a ring-shaped elastic element such as a compression spring. Thus, the movement direction can be constrained by the engagement between the limiting holes 11 and the limiting posts 4, ensuring that the bonding plate 2 can only move along the axial direction of the limiting posts 4. This effectively prevents gaps from forming between the bonding plate 2 and the connecting vertical plate 14 during movement, which would affect subsequent resin filling. Each elastic element 3 can only deform in its axial direction, preventing lateral bending or twisting, thereby ensuring the effectiveness of each elastic element 3.

[0033] Each limiting post 4 is provided with a limiting plate 43 at the end away from the bonding plate 2 to limit its own movement distance, thereby preventing each limiting post 4 from disengaging from the limiting hole under the action of the elastic member 3, causing the bonding plate 2 to disengage from the frame body 1.

[0034] Each limiting plate 43 is integrally formed with each limiting post 4 to ensure the connection stability between the limiting plate 43 and the limiting post 4.

[0035] Example 2

[0036] Based on Example 1, such as Figure 2 , Figures 4-5 As shown, the bonding plate 2 in this embodiment is provided with several rotating frames 21. The end of each limiting post 4 close to the rotating frame 21 is rotatably connected to each rotating frame 21. Due to individual differences among patients, some patients' teeth may be tilted, causing the bonding plate 2 to only partially contact the missing tooth when it is bonded to the missing tooth, affecting the fit between the bonding plate 2 and the missing tooth.

[0037] After the rotating frame 21 and the limiting post 4 are rotated and connected, the sliding movement of each limiting post 4 is relatively independent. With the help of the connection between each limiting post 4 and the rotating frame 21, the bonding plate 2 can present an inclined structure, so as to cooperate with the inclined missing tooth, making the filled resin repair body more similar to its original tooth (missing tooth), such as having the same inclined angle of the original tooth.

[0038] Each limiting post 4 has a rotating body 41 at one end near the bonding plate 2. The rotating body 41 has a rotating shaft 42 for rotatably connecting with the rotating frame 21. The rotating body 41, rotating shaft 42, and limiting post 4 are integrally formed to ensure the connection strength between them. The rotation axis between each limiting post 4 and the rotating frame 21 is perpendicular to the horizontal plane. Correspondingly, the central axis of the rotating shaft 42 is perpendicular to the horizontal plane, thereby constraining the tilt direction of the bonding plate 2 and preventing the opening of the frame body 1 from being closed due to the tilt of the bonding plate 2.

[0039] Preferably, each rotating frame 21 includes two rotating plates 211, and each rotating plate 211 is provided with a rotating hole 2111 for the rotatable connection of the limiting post 4; each rotating plate 211 is symmetrically and evenly distributed with the limiting post 4 as the center, ensuring that the rotating frame 21 can provide a balanced force point for the limiting post 4, so that the force on the limiting post 4 can be evenly distributed on both sides, avoiding excessive force on one side, which would damage the rotatable connection structure between the limiting post 4 and the bonding plate 2, and affect the rotatable connection relationship between the two.
