Description

Technical Field

[0001] The utility model relates to the technical field of denture installation, in particular to a removable prosthesis connecting component. Background Art

[0002] Locator implant overdenture is a complete denture restoration system that combines implants and attachments. It is achieved by implanting implants in the mouth and using attachments (such as rod-type attachments, snap-on attachments, and magnetic attachments) to firmly connect the denture to the implants. Currently, the mandibular full-mouth overdenture implant system, which uses two implants and locator attachments for retention, has good stability, a high retention rate, and can be safely used in clinical practice. Figure 1 The implant mainly provides retention force, and the force load is mainly borne by the alveolar ridge mucosa; two implants can significantly improve the stability and retention of dentures through ball caps, rod clamps or magnetic attachments, but have the following technical defects: under the influence of food residues, saliva, and plaque, the retention force decreases, the rod of the implant is easy to break, and the restoration method of implant connection belongs to the third category, which is costly.

[0003] Therefore, how to design a removable prosthesis connection component has become an urgent problem to be solved. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a removable prosthesis connecting component to solve at least one of the above technical problems.

[0005] The technical solution of the utility model is: a removable prosthesis connecting component, including a connecting piece installed on the denture, the connecting piece is made by 3D printing technology, the connecting piece is a U-shaped structure with an opening downward, a U-shaped notch is provided on the corresponding part of the denture and the connecting piece, and the U-shaped structure is installed on the U-shaped notch.

[0006] The utility model adopts a U-shaped structure with a downward opening as a connecting part. The U-shaped structure is installed on the U-shaped notch of the denture. The embedding of the U-shaped structure and the U-shaped notch produces a strong retention force. The building block splicing method is realized through 3D printing technology and can be applied to any Class II restoration, which is convenient for repair and installation and reduces production costs.

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] See Figure 1-3 The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read. They are not used to limit the conditions for the implementation of this utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by this utility model without affecting the efficacy and purpose that can be achieved by this utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit the scope of the implementation of this utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of this utility model without substantially changing the technical content.

[0013] Example 1: A removable prosthesis connecting component, referring to Figure 2 The invention comprises a connector 1 mounted on the denture, the connector 1 being manufactured using 3D printing technology. The connector 1 is a downward-opening U-shaped structure, and a U-shaped notch is provided at a portion of the denture corresponding to the connector 1, and the U-shaped structure is mounted on the U-shaped notch. The present invention uses a downward-opening U-shaped structure as a connector, which is mounted on the U-shaped notch of the denture. The interlocking of the U-shaped structure and the U-shaped notch generates a strong retention force. The invention utilizes 3D printing technology to achieve a building block splicing method that can be applied to any Class II restoration, making repair and installation convenient and reducing production costs.

[0014] Example 2: Based on Example 1, a cylindrical tube 2 is provided on the closed end of the connector 1, located on the side away from the opening of the U-shaped structure. This utility model employs a cylindrical tube provided on the closed end of the connector. The cylindrical tube and the connector are connected using 3D printing technology in a building block-like manner and can be applied to any Class II prosthesis, facilitating repair and installation while reducing production costs.

[0015] Example 3: Based on Example 2, refer to Figure 3 The cylindrical tube 2 is provided with an inner hole 3, and the inner hole 3 can penetrate the closed end of the connector 1. The utility model adopts the method of providing the inner hole on the cylindrical tube, which is convenient for repair and installation.

[0016] In specific implementation, the connector 1 is a 5mm×5mm×4.5mm cuboid, and the opening width of the U-shaped structure is 3mm×3mm; the outer diameter of the cylindrical tube 2 is 4mm and the height is 1.5mm; the diameter of the inner hole 3 is 2mm.

[0017] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
