Description

Technical Field

[0001] The utility model relates to the field of dental implants, in particular to an anodized fixture for an oral healing abutment. Background Art

[0002] An oral healing abutment is a temporary auxiliary device used to connect the implant to the gums during dental implant surgery, or as a temporary abutment for initial use. Its main function is to ensure that the internal structure of the implant is clean and blood-free, help soft tissue cover and stabilize the implant, and provide support and protection for the long-term healing of the implant. In addition, the healing abutment can also help shape the gum cuff, creating conditions for the subsequent installation of permanent restorations (such as crowns).

[0003] Figure 1 This is a schematic diagram of the structure of a commonly used healing abutment, which has a cylindrical anode portion 4 (within the dotted line) that needs to be anodized (oxidized) and a condensation portion containing an end screw 1. The condensation portion also includes a conical portion 3, an arc transition portion located above the conical portion 3, and an annular end face 2 located below the conical portion. Anodizing the cylindrical anode portion 4 can not only improve the biocompatibility of the healing abutment, but also form a hard surface oxide film, thereby significantly improving the mechanical strength of the healing abutment. However, during the above-mentioned anodizing process, it is necessary to avoid other parts of the healing abutment, especially the conical portion 3, because if the conical portion 3 is anodized, there will be a gap between the taper of the healing abutment and the implant. After the operation is completed, saliva, food residues, blood and bacteria may invade the internal structure of the implant, resulting in infection and other problems. Utility Model Content

[0004] The purpose of the utility model is to provide an anodizing jig for an oral healing abutment, which can conveniently and effectively perform selective anodizing treatment on the healing abutment.

[0005] According to the utility model, an anodized fixture for an oral healing abutment is provided, wherein the oral healing abutment has a cylindrical anode portion and a condensation portion including an end screw, and the anodized fixture for an oral healing abutment includes:

[0006] A base having a circumferential groove and a threaded blind hole opening upward;

[0007] The main body comprises a receiving cavity for receiving the condensation portion of the oral healing abutment and a fixing screw located below the receiving cavity, wherein the fixing screw is threadedly connected to the threaded blind hole of the base, the upper portion of the receiving cavity forms a circular hole opening, an annular platform is formed between the middle and upper portions of the receiving cavity, and the lower portion of the receiving cavity forms a threaded hole for threading the end screw of the condensation portion of the oral healing abutment; and

[0008] The O-ring is positioned in the circular opening of the receiving cavity of the main body through the annular platform and is used for sealingly sleeved on the condensation portion adjacent to the cylindrical anode portion of the oral healing base.

[0009] According to the oral healing abutment anodizing jig of the present invention, the diameter of the circular opening of the receiving cavity of the main body is no larger than the diameter of the cylindrical anode portion of the oral healing abutment. This ensures that the cylindrical anode portion is fully exposed and effectively anodized.

[0010] According to the anodized jig for oral healing abutment of the present invention, the receiving cavity of the main body and the condensed portion of the oral healing abutment have similar shapes or substantially identical shapes.

[0011] According to the anodized fixture for oral healing abutments of the present invention, the O-ring is made of a corrosion-resistant elastic material, such as an acid- and alkali-resistant rubber material.

[0012] According to the oral healing abutment anodizing jig of the present invention, the base and the main body are made of the same material as the oral healing abutment or its cylindrical anode portion, which can avoid the introduction of other impurities during the anodizing process.

[0013] The oral healing abutment anodizing fixture of the present invention has at least the following advantages:

[0014] (1) The threaded connection between the oral healing base and the anodized fixture makes disassembly and assembly quick and easy, and at the same time achieves reliable pressure sealing of the non-anodized part.

[0015] (2) The quick-detachable connection between the main body of the anodizing fixture and the base of the anodizing work hanger can be applied to products of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] Figure 2 This is a cross-sectional view of the assembly structure of the anodizing fixture according to the present invention. Figure 3 for Figure 2 Detailed schematic diagram of the base of the anodizing fixture shown. Figure 4 for Figure 2 Detailed schematic diagram of the main body of the anodizing jig shown, Figure 5 for Figure 2 Detailed diagram of the O-ring of the anodizing fixture shown in the figure. Figure 2-5 As shown, the anodized fixture of the present invention generally comprises a base 5, a main body 6 and an O-ring 7. The base 5 and the main body 6 are made of the same material as the oral healing abutment. The O-ring 7 is made of a corrosion-resistant elastic material.

[0024] like Figure 2 and Figure 3 As shown, the base 5 has a circumferential slot 8, a threaded blind hole 9 with an upward opening, and an upper surface 10. The slot 8 can be clamped on the hanger of the anodizing equipment to achieve accurate positioning of the fixture.

[0025] like Figure 2 and Figure 4 As shown, the lower part of the main body 6 has a fixing screw 11 and a lower annular surface 12 around it, and the upper part is formed with Figure 1 The receiving cavity is formed in the same or similar shape as the condensation portion of the oral healing base shown. A circular hole opening 16 is formed in the upper portion of the receiving cavity, an annular platform 15 is formed between the middle and upper portions of the receiving cavity, and a threaded hole 13 is formed in the lower portion of the receiving cavity. The diameter of the circular hole opening 16 is not larger than the diameter of the cylindrical anode portion 4 of the oral healing base. An annular platform 14 is also formed in the middle portion of the receiving cavity, which is substantially consistent in shape with the annular end face 2 of the condensation portion of the oral healing base. The fixing screw 11 is threadedly fitted with the threaded blind hole 9 of the base 5 until the upper surface 10 of the base 5 abuts against the lower annular surface 12 of the main body 6.

[0026] like Figure 2 and Figure 5 As shown, the O-ring 7 has a lower edge 17 and an outer edge 18. The lower edge 17 abuts against the annular platform 15, while the outer edge 18 abuts against the sidewall of the circular opening 16 or forms an interference fit therewith. The inner diameter of the O-ring 7 is no greater than the maximum outer diameter of the conical surface portion 3 of the oral healing abutment.

[0027] Figure 6 for Figure 1 The oral healing abutment shown is Figure 2 The schematic diagram of the anodizing fixture shown is used in an anodizing tank. Figure 6 As shown, the end screw 1 of the oral healing base is screwed into the threaded hole 13 to form a threaded connection. At this time, the exposed cylindrical anode part 4 of the oral healing base presses down the O-ring 7 set in the circular hole opening 16, so that the O-ring 7 is tightly fitted on the arc transition part (or conical surface part 3) of the condensation part adjacent to the cylindrical anode part 4 of the oral healing base, thereby effectively blocking the contact between the anodized liquid in the working tank and the conical surface part 3.
