Description

Technical Field

[0001] The utility model relates to the technical field of dentistry, in particular to a fixing mechanism for oral dentures. Background Art

[0002] Dental implant technology is currently the most respected method for restoring missing teeth in the oral medicine field. It achieves the purpose of restoring missing teeth by implanting artificial tooth roots in the alveolar bone and then installing porcelain teeth. Compared with traditional dental bridges and removable dentures, dental implants have higher stability, comfort and similarity, allowing patients to enjoy the chewing power and pronunciation effects of real teeth even when they are missing teeth.

[0003] However, in the prior art, the connection between the artificial tooth root and the porcelain tooth is usually fixed by bonding, which makes it easy for the connection between the artificial tooth root and the porcelain tooth to break during long-term use, resulting in the defect of a loose connection between the porcelain tooth.

[0004] Based on this, the utility model designs a fixing mechanism for oral dentures to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a fixing mechanism for oral dentures to solve the above technical problems.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: comprising an implant and a dental crown; a support rod is fixedly arranged on the implant, and a connecting thread is provided on the support rod; a base is fixedly arranged on the dental crown, and a clearance hole is provided on the base, a connecting nut is rotatably arranged in the clearance hole, and the connecting nut is threadedly connected to the connecting thread.

[0007] Preferably, a guide platform is fixedly provided on the implant, a clearance groove is provided on the base, and the guide platform is slidably provided in the clearance groove.

[0008] Preferably, a sealing material is filled between the implant and the abutment.

[0009] Preferably, the connecting nut is a magnetic nut.

[0010] In summary, the present application has the following beneficial technical effects: the implant and the crown are connected together by the magnetic nut, which is not prone to falling off and has the advantage of a firm connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The following is combined with Figure 1 —3 Provide further details of this application.

[0019] A fixing mechanism for an oral denture comprises an implant 1 and a crown 2.

[0020] A support rod 3 is fixedly arranged on the implant 1 , and a connecting thread 4 is formed on the support rod 3 ; a guide platform 5 is fixedly arranged on the implant 1 .

[0021] A base 6 is fixedly arranged on the crown 2 , a clearance hole 7 is opened on the base 6 , a connecting nut is rotatably arranged in the clearance hole 7 , and the connecting nut is a magnetic nut 8 ; a clearance groove 9 is opened on the base 6 .

[0022] The guide platform 5 is slidably disposed in the clearance groove 9 , and the connecting nut is threadedly connected to the connecting thread 4 ; and a sealing material 10 is filled between the implant 1 and the base 6 .

[0023] The implementation principle of this embodiment is as follows: when installing the denture, the implant 1 is first fixed in the alveolar bone; then the base 6 is placed on the implant 1 through the positioning of the guide platform 5 and the clearance groove 9, so that the installation direction and position of the crown 2 are accurate; by using a magnetic drive device, the magnetic drive device generates a rotating magnetic field, and when the magnetic drive device is close to the base 6, it is affected by the rotating magnetic field, and the magnetic nut 8 rotates in the clearance hole 7 until the magnetic nut 8 is threadedly connected to the connecting thread 4, so that the base 6 is fixed on the implant 1; then the sealing material 10 is filled in the gap between the implant 1 and the base 6, so that the clearance hole 7 is isolated from the external environment to prevent the connecting nut from being damaged.

[0024] The implant 1 and the crown 2 are connected together by the magnetic nut 8, which is not easy to fall off and has the advantage of a firm connection.

[0025] In the description of the present invention, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "the other end", "upper", "one side", "top", "inside", "front", "center", "both ends" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
