Description

Technical Field

[0001] The present application relates to the technical field of medical oral implants, and in particular to an auxiliary identification component and an implant substitute. Background Art

[0002] Implant-supported upper restorations can be used to repair missing teeth. Before formal restoration, the orientation of the anti-rotation structure inside the implant and the gingival morphology shaped by the temporary restoration need to be transferred. In this process, the scanning rod and the temporary restoration need to be connected to the implant substitute respectively, and then the overall shape is obtained using an optical scanner, and then the two data are fitted together through the common structure on the substitute. In this way, the position of the temporary restoration relative to the implant can be obtained at the same time. The formal restoration designed based on this position can completely replicate the gingival morphology of the temporary restoration, which is conducive to maintaining a good aesthetic shape. However, the current mainstream implant substitute is a cylindrical structure, and there is no specific structure on its outer surface, making it difficult to form a definite correspondence with the internal anti-rotation structure. When it is scanned and used as a fitting reference, the cylindrical structure is difficult to provide an identifiable reference point, which can easily lead to fitting errors, and thus the correct positional relationship between the gingival morphology and the anti-rotation structure cannot be determined.

[0032] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with examples and drawings. The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.

[0033] First, as Figure 1As shown, an embodiment of the present application provides an auxiliary identification component, which includes a retaining ring 1. The retaining ring 1 can be configured as a polymer material ring such as polyetheretherketone, polyetherketoneketone, polyamide (nylon), polymethyl methacrylate, polylactic acid, and polycarbonate, or can be configured as a stainless steel or aluminum alloy ring. The retaining ring 1 has a connecting portion 2 and an identification portion 3. The retaining ring 1 as a whole can be configured as a circular ring to facilitate cooperation with the main body 4 of the implant substitute, that is, the retaining ring 1 can be coaxially sleeved on the main body 4 of the implant substitute. In other embodiments, the retaining ring 1 can also be configured as an annular body such as a square ring, a triangular ring, and an elliptical ring; wherein the connecting portion 2 is used to connect the implant substitute; the identification portion 3 is located radially outside the retaining ring 1 and is constructed as a polyhedron structure.

[0034] The auxiliary identification part provided in the embodiment of the present application has a simple structure, is easy to manufacture and is convenient to use. Through the setting of the connecting part 2, the retaining ring 1 and the main body 4 can be connected after the retaining ring 1 is sleeved on the main body 4 of the implant substitute, and the identification part 3 on the radially outer side of the retaining ring 1 is constructed as a polyhedral structure. The polyhedral structure has specific shape characteristics. For example, the polyhedral structure itself has vertices where multiple faces intersect. Based on the vertices, it is convenient for the scanner to identify and scan it. The vertex can also be used as a reference point in the data splicing and fitting process after the scan, so as to ensure the correct fitting and the accuracy after fitting, which is conducive to determining the correct positional relationship between the gingival morphology and the anti-rotation structure.

[0035] There is no limitation on the connection method between the connecting part 2 and the implant substitute, as long as the retaining ring 1 can be kept in a state after being sleeved on the main body 4, such methods can be adopted, such as clamping, welding, bonding, tight connection, and magnetic connection. When magnetic connection is adopted, the retaining ring 1 can be configured as a magnetized metal ring (the main body 4 of the implant substitute is usually a component that can be magnetically adsorbed). In order to facilitate implementation and improve the convenience during the connection process and the stability after connection, in some optional embodiments, the connecting part 2 can be constructed as a channel that passes through the radial outside and radial inside of the retaining ring 1. The number of connecting parts 2 can be unlimited and can be one or more. In actual implementation, an adhesive can be injected into the channel. The adhesive can be a light-curing fluid resin. Since the channel passes through the retaining ring 1, the adhesive can form a bond with the implant substitute, and the adhesive can form a bond with the hole wall of the channel. After the adhesive solidifies, the retaining ring 1 and the implant substitute can be kept relatively fixed, which is convenient to operate and easy to implement.

[0036] When the connecting portion 2 is constructed as a channel, the extension direction of the connecting portion 2 can be a curve, a straight line, a broken line or a combination of any two / three of the foregoing, that is, the connecting portion 2 can be a curved and extended channel, a combination of multiple holes, or a straight hole whose extension direction is perpendicular to the axial direction of the retaining ring 1, wherein the combination of multiple holes can be a combination of curved holes and curved holes, or a combination of curved holes and straight holes, that is, as long as the adhesive is injected into the channel, the adhesive can simultaneously form a bond with the implant substitute and the channel wall. In order to facilitate manufacturing and ensure good dimensional accuracy during the manufacturing process, in some optional embodiments, the extension direction of the connecting portion 2 is a straight line. In actual implementation, the extension direction of the connecting portion 2 can coincide with the radial direction of the retaining ring 1. In other embodiments, the extension direction of the connecting portion 2 can also be eccentrically perpendicular to the axial direction of the retaining ring 1, and its extension direction can also form an angle or an eccentric angle with the axial direction of the retaining ring 1.

[0037] It should be noted that, as long as the channel in the embodiment of the present application can pass through the radial outer side and the radial inner side of the retaining ring 1, the cross-sectional shape of the channel can be the same or different. For example, the channel can be a standard circular hole, that is, the cross-sectional shape of the channel is a circle of the same size everywhere. The channel can also be a conical hole, that is, the channel can be a type that contracts or expands from the radial outer side to the radial inner side of the retaining ring 1. The channel can also be a combination of a square hole and a circular hole, that is, from the radial outer side to the radial inner side of the retaining ring 1, the channel is a circular hole and a square hole respectively. The circular hole section is convenient for the injection of the adhesive, and the square hole can be a groove body extending circumferentially along the retaining ring 1. That is to say, in actual implementation, an annular groove connected to the circular hole can be opened on the radial inner side of the retaining ring 1. The annular groove serves as a square hole, that is, the square hole is an open channel. When the retaining ring 1 is sleeved on the implant substitute, the open channel can be closed by the implant substitute, so that after the adhesive is injected, a larger adhesion area can be formed between the implant substitute and the implant substitute. In other embodiments, the aforementioned square hole may also be implemented as a circular annular channel or an annular channel with other cross-sectional shapes.

[0038] When the retaining ring 1 is connected to the main body 4 of the implant substitute by an adhesive, the contact area between the adhesive and the main body 4 will directly affect the relative stability of the main body 4 of the implant substitute and the retaining ring 1. In theory, the larger the contact area between the adhesive and the main body 4, the better the relative stability of the main body 4 and the retaining ring 1. This requires that the connecting portion 2 configured as a channel has a larger flow area. However, when the flow area is too large, the adhesive is easy to lose before forming, that is, the adhesive may partially detach from the main body 4. Therefore, in some optional embodiments, the flow cross-sectional area of ​​the connecting portion 2 is configured to be 0.19~1.8mm 2, the flow cross-sectional area can be suitable for the commonly used main body 4 with a diameter of 2 to 6 mm. In the embodiment of the present application, if the connecting portion 2 is specifically configured as a tapered channel, it means that the minimum diameter of the tapered channel can be 0.5 mm and the maximum diameter can be 1.5 mm; if the connecting portion 2 is specifically configured as a straight circular channel, that is, the cross-sectional profile of the connecting portion 2 is circular everywhere, it means that the diameter of the circular channel is 0.5 to 1.5 mm.

[0039] In some optional embodiments, when the connecting portion 2 is constructed as a channel structure, in order to facilitate the adhesive to remain in the channel, the radial thickness of the retaining ring 1 is configured to be 0.3-3 mm.

[0040] In some optional embodiments, the axial length of the retaining ring 1 is configured to be 2-15 mm.

[0041] In some optional embodiments, the number of identification parts 3 is configured to be multiple; wherein the multiple identification parts 3 are arranged at unequal intervals along the circumference of the retaining ring 1; or the multiple identification parts 3 are arranged at intervals along the axial direction of the retaining ring 1.

[0042] In the embodiment of the present application, the shape structures of the multiple identification parts 3 can be the same or different; when the shape structures of the multiple identification parts 3 are different, for example, the multiple identification parts 3 can be square blocks, diamond blocks, triangular blocks, star blocks, etc., respectively, and the multiple identification parts 3 can be arranged at intervals in any manner on the radial outer wall of the identification part 3. For example, in actual implementation, the multiple identification parts 3 can be arranged equidistantly or unequally along the circumference of the retaining ring 1, or the multiple identification parts 3 can be arranged equidistantly or unequally along the axial direction of the retaining ring 1; when the shape structures of the multiple identification parts 3 are the same, the multiple identification parts 3 are arranged unequally along the circumference of the retaining ring 1, or the multiple identification parts 3 are arranged at intervals along the axial direction of the retaining ring 1, so as to avoid the situation where the fitting points selected on the multiple identification parts 3 are centrally symmetrical.

[0043] Second, the Figure 2 As shown, an embodiment of the present application provides an implant substitute, which includes a main body 4 and an auxiliary identification piece as in the first aspect; wherein the auxiliary identification piece is connected to the main body 4 via a connecting portion 2.

[0044] In actual implementation, the main body 4 is usually a cylinder, and thus the retaining ring 1 of the auxiliary identification component is constructed as a circular ring; after the retaining ring 1 is sleeved on the main body 4, the axial end face of the retaining ring 1 is flush with the end face of the main body 4, and an adhesive is injected into the connecting portion 2 constructed as a channel to achieve a fixed connection between the retaining ring 1 and the main body 4, thereby ensuring the stability of the connection between the two.

[0045] When scanning using the implant substitute provided in the embodiment of the present application, the scanning rod is connected to the main body 4 of the implant substitute, and an optical scanner is used to obtain the overall shape to establish a first model. The scanning rod is removed, and the temporary restoration is connected to the main body 4 of the implant substitute. The optical scanner is then used to obtain the overall shape to establish a second model. At least three fitting points with the same position are selected on the identification part 3 in the first model and the second model, and the first model and the second model are fitted. Then, a more accurate positional relationship between the temporary restoration's gingival morphology and the anti-rotation structure can be obtained based on the fitted model.
