Description

Technical Field

[0001] The invention relates to the field of oral technology, and in particular to a rapid mold-taking device for oral implantation. Background Art

[0002] Oral implants, also known as dental implants, are surgically implanted into the upper and lower jaws of the human body at the site of tooth loss. After the surgical wound heals, a device to repair dentures is installed on the upper part. With the continuous advancement of edentulous implant technology, more and more edentulous patients are choosing implant restoration solutions, and the upper restoration of edentulous patients mostly uses screw-retained implant bridges.

[0003] The dental implant process in the prior art is as follows: an implant base is fixed in the oral jawbone, and then a composite abutment is threadedly connected above the implant base. A protective cap is first fixed on the upper surface of the composite abutment to stretch and shape the gums around the composite abutment. The protective cap is then removed and taken out. A transfer rod is then connected above the composite abutment for modeling. After modeling, the transfer rod is removed and taken out, and delivered to the clinic for implant impression making. The protective cap is then threadedly connected to the composite abutment again, and the protective cap is removed again when the denture is installed.

[0004] However, the above-mentioned implantation process and the mold-taking device used have the following problems: the above-mentioned process requires repeated removal and installation of the protective cap, which is a small metal part. During the removal and installation process, due to the limited operating space in the oral cavity, it is easy for the protective cap to fall into the oral cavity, greatly increasing the risk of dental implants. In addition, the traditional mold-taking device has cumbersome steps and a long time in the process of rigid connection, and the long operation time in the patient's mouth is likely to cause discomfort to the patient. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a rapid mold-taking device for oral implantation.

[0006] The present invention is achieved through the following technical solutions:

[0007] A rapid mold-taking device for oral implantation comprises a positioning cap, a window transfer rod and a window screw, wherein the upper part of the positioning cap is provided with a positioning cap upper part, the interior of the positioning cap upper part is provided with a screw hole and an internal thread from top to bottom, the lower part of the positioning cap is provided with a second external thread, the outer periphery of the second external thread is provided with a first positioning groove, the interior of the window transfer rod is penetrated from top to bottom with a channel and a second positioning groove, the second positioning groove is connected to the upper part of the positioning cap by snapping, the lower end of the window screw is provided with a straight rod, a threaded portion and a third external thread in sequence from top to bottom, the lower end of the window screw passes through the channel and the second positioning groove in sequence and is inserted into the screw hole and the interior of the internal thread, the third external thread is threadedly connected to the internal thread, the threaded portion is snap-fitted with the screw hole, and the bottom of the positioning cap is connected to the top of the composite base.

[0008] The bottom of the positioning cap is threadedly connected to the top of the composite base, and the second external thread is threadedly connected to the thread groove.

[0009] A conical surface section is arranged outside the bottom end of the positioning cap, and the outer diameter of the bottom surface of the positioning cap is the same as the outer diameter of the composite base.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The structure design of the rapid mold taking device of the present invention is more reasonable. The rapid mold taking device includes a positioning cap and a window transfer rod. After the positioning cap is connected to the composite base, it does not need to be repeatedly disassembled and assembled, and can serve as a protective cap. At the same time, the upper part of the positioning cap can be directly connected to the window transfer rod for modeling operation, and the positioning cap does not need to be disassembled and assembled multiple times. This not only reduces the steps of mold taking, but also reduces the risk of the positioning cap falling into the oral cavity during the disassembly and assembly process, and is more convenient and safe to use.

[0012] In the present invention, a conical section is provided on the outside of the bottom end of the positioning cap, and the outer diameter of the bottom surface of the conical section is the same as the outer diameter of the composite base, which can not only ensure a smooth transition at the connection between the protective cap and the composite base, but also increase the overall outer diameter of the positioning cap, making it more convenient to use.
