AI Technical Summary
In the prior art, it is difficult to effectively protect the open end face of the oral implant during the acid etching process, resulting in the transitional growth of osteocytes affecting the coordination with the abutment.
A oral implant end face protection acid etching fixture is designed, including the main body, screw and elastic gasket. It can achieve rapid combination through threaded connections. The elastic gasket abuts the open end face to prevent acid corrosion.
Effective protection of the open end surface during the acid etching process is achieved to ensure that the subsequent coordination between the implant and the abutment is not affected.

Abstract
Description
Technical Field
[0001] The utility model relates to an acid etching tool which is particularly suitable for oral implants. Background Art
[0002] Oral implants are also called dental implants or artificial tooth roots. Figure 1 The figure shows a schematic structural diagram of a commonly used oral implant SAT, which has an external thread 1, an internal thread 2 and an open end face 3. The open end face 3 is a smooth surface and serves as a platform for connecting the oral implant to the abutment. The oral implant is surgically implanted into the upper or lower jaw of the human body in the edentulous part. After the surgical wound heals, the thread is integrated with the upper or lower jaw. Before the implant is used, it is usually necessary to perform acid etching to form a microporous structure at the thread, enhance its surface roughness and thereby increase the bone contact area, promote bone integration, and improve the initial stability of the oral implant.
[0003] The open end surface cannot be acid-etched during the above-mentioned acid etching process. Once the open end surface is corroded, bone cells will transition to the open end surface after the oral implant is implanted, thereby affecting its subsequent cooperation with the abutment. Utility Model Content
[0004] The purpose of the utility model is to provide an acid etching jig for oral implants, which can at least effectively protect the open end surface of the oral implant during the acid etching process.
[0005] According to the utility model, an acid etching jig for protecting the end face of an oral implant is provided, wherein the oral implant has an open end face and an internal thread, and the acid etching jig comprises:
[0006] The main body has a threaded blind hole opening upward;
[0007] A screw having an upper threaded portion, a middle smooth portion and a lower threaded portion, wherein the lower threaded portion of the screw forms a threaded connection with the threaded blind hole of the main body;
[0008] The elastic gasket is sleeved on the middle polished rod portion of the screw through the central opening formed on it. When the upper threaded portion of the screw forms a threaded connection with the internal thread of the oral implant, the upper surface of the elastic gasket abuts against the open end face of the oral cavity implant.
[0009] In the oral implant end face protection and acid etching jig of the present invention, the diameter of the elastic gasket's central opening is preferably smaller than the diameter of the middle polished portion of the screw, so that the two form an interference fit. In this case, the diameter of the elastic gasket's central opening can be no smaller than the maximum outer diameter of the upper threaded portion of the screw, facilitating smooth assembly.
[0010] According to the present invention, the main body of the oral implant end face protection acid etching jig preferably has a stepped shaft outer profile, including an upper platform and a lower fixed shaft. This outer profile shape facilitates rapid fixation for operations such as sandblasting and acid etching.
[0011] According to the oral implant end face protection acid etching jig of the present invention, the lower surface of the elastic gasket is preferably arranged flush with the upper surface of the upper platform of the main body to seal the threaded blind hole of the main body.
[0012] The acid etching jig of the present invention, including the elastic gasket, is preferably made of acid corrosion resistant material.
[0013] The utility model has at least the following advantages:
[0014] (1) The acid etching fixture can be quickly disassembled and assembled by threading or disengaging the internal thread of the oral implant with the upper thread of the screw;
[0015] (2) During the above-mentioned threaded connection process, the opening end face of the oral implant and the elastic gasket are simultaneously pressure-contacted, thereby effectively protecting the opening end face from acid corrosion;
[0016] (3) The acid etching fixture is easy to fix due to its stepped shaft outer profile, so as to perform operations such as sandblasting and acid etching. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described below with reference to the accompanying drawings.
[0025] Figure 2 Schematic diagram of the assembly structure of the acid etching jig according to the utility model; Figure 3 for Figure 2 Exploded view of the acid etching fixture shown; Figure 4 for Figure 2 A detailed schematic diagram of the main body of the acid etching jig shown; Figure 5 for Figure 2 Detailed schematic diagram of the screw of the acid etching fixture shown; Figure 6 Then Figure 2 Detailed diagram of the elastic gasket of the acid etching fixture shown. Figure 2-6 As shown, the acid etching fixture F of the present invention generally includes a main body 4, a screw 5 and an elastic gasket 6.
[0026] like Figure 4 As shown more clearly, the main body 4 has a three-step shaft profile, including an upper platform 8 and a lower fixed shaft. The lower fixed shaft can be inserted into the fixing holes of the sandblasting machine spindle and the acid etching tank plate to achieve precise positioning of the jig. The main body 4 also has a threaded blind hole 7 opening upward.
[0027] like Figure 5 As shown more clearly, the screw 5 has an upper threaded portion 11, an intermediate polished portion 10 and a lower threaded portion 9. The lower threaded portion 9 of the screw 5 forms a threaded connection with the threaded blind hole 7 of the body 4. The diameter of the intermediate polished portion 10 can be slightly larger than the maximum outer diameter of the upper threaded portion 11 and the lower threaded portion 9.
[0028] like Figure 6 As shown more clearly, the elastic gasket 6 has a lower surface 12 and an upper surface 13. The elastic gasket 6 is also formed with a central opening, the diameter of which is slightly smaller than the diameter of the middle polished portion 10 of the screw 5 so that the two can form an interference fit. The central opening of the elastic gasket 6 can be slightly larger than the maximum outer diameter of the upper threaded portion 11 of the screw 5 to facilitate smooth assembly. Figure 2 The elastic gasket 6 is sleeved on the middle polished rod portion 10 of the screw 5 through the central opening formed thereon, and the lower surface 12 of the elastic gasket 6 is flush with the upper surface of the upper platform 8 of the main body 4.
[0029] Figure 7 for Figure 1 The oral implants shown are Figure 2 The diagram of the acid etching jig shown is used in the acid etching tank. Figure 7As shown, the upper threaded portion 11 of the screw 5 forms a threaded connection with the internal thread 2 of the oral implant SAT. During the connection process, the open end face 3 of the oral implant SAT automatically abuts and embeds into the upper surface 13 of the elastic gasket 6 (the embedding amount can be adjusted by the degree of screwing), thereby achieving effective isolation from the etching liquid.
