Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically relating to a positioning and clamping device for a customized implantation abutment and accessories. Background Technology

[0002] Personalized abutments are increasingly used in dental implantology because they better adapt to the gingival morphology within the mouth, meet the diverse needs of implant superstructure restorations, and provide patients with better treatment outcomes. Currently, the manufacturing process for personalized abutments typically involves first machining a semi-finished product with a matching target implant interface shape and screw channels using CNC machining. Then, during the restoration stage, the superstructure restoration is designed according to different needs, and dental CAD / CAM technology is used to cut it to the designed shape to complete the entire personalized abutment.

[0003] However, existing abutment positioning and clamping devices have many problems in practical applications. On the one hand, some clamping devices lack sufficient precision in the fit between the clamping part and the fixture, which can lead to excessive deviations in the machining shape and, in severe cases, repair failure. For example, in some traditional clamping methods, loosening can easily occur between the semi-finished product and the fixture, which not only significantly increases machining errors but also makes it difficult to maintain the consistency of the design shape. This inconsistency necessitates rescanning the hand-polished abutment and redesigning and machining the crown when fabricating the superstructure, resulting in the inability to process the personalized abutment and superstructure simultaneously, greatly reducing production efficiency.

[0004] On the other hand, some clamping solutions are closed, and processing can only be carried out at 0-180°. The deviation of the perforation part is relatively large. The integrity of the interface part is directly related to whether the product can be successfully matched with the target implant. Once damaged, the entire product will be unusable, resulting in processing failure and wasting a lot of manpower, material resources and time costs.

[0005] In summary, existing abutment positioning and clamping devices are no longer sufficient to meet the needs of efficient and precise processing of personalized abutments. There is an urgent need to develop positioning and clamping devices for customized planting abutments and accessories to solve the above-mentioned technical problems and improve the processing quality and efficiency of personalized abutments.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0025] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] like Figures 1-5As shown, this application discloses a positioning and clamping device for a customized planting base and accessories, including a clamping body. The clamping body is provided with a clamping through hole, which penetrates the clamping body and fixes the customized base to be processed through the clamping through hole. Specifically, the clamping through hole includes a locking threaded hole 4 and a positioning hole 7. The locking threaded hole 4 and the positioning hole 7 are interconnected and coaxially arranged. The locking threaded hole 4 is adapted to a locking screw. The positioning hole 7 is adapted to a positioning end 5 of the base. The positioning end 5 of the base is provided with a fixing threaded hole 8 adapted to the locking screw. During operation, the locking threaded hole 4, the positioning hole 7, and the fixing threaded hole 8 are coaxially arranged.

[0027] In a further embodiment, the outer diameter of the positioning end 5 of the base is larger than the diameter of the locking threaded hole 4, and a stepped hole is formed between the locking threaded hole 4 and the positioning hole 7, through which the positioning between the base to be processed and the clamping body is achieved.

[0028] In a further embodiment, the positioning hole 7 is a circular hole, and a first positioning plane is provided on the inner sidewall of the positioning hole 7. A second positioning plane 11 adapted to the first positioning plane is provided on the outer circumferential sidewall of the base positioning end 5. The positioning hole 7 and the base positioning end 5 are positioned by means of the first positioning plane and the second positioning plane 11, preventing the base positioning end 5 from rotating within the positioning hole 7.

[0029] In a further embodiment, the outer diameter of the positioning end 5 of the base is smaller than the outer diameter of the base to be processed part 6. By abutting the outer wall of the clamping body against the side wall of the base to be processed part 6, further positioning between the base to be processed and the clamping body is achieved.

[0030] In a further embodiment, the clamping body includes a connecting plate 1 and a clamping column 2. One end of the clamping column 2 is fixed to the connecting plate 1. The connecting plate 1 is provided with a mounting hole 9 for connecting to the host 10. The clamping body is rotatably connected to the host 10, enabling the processing of the base-to-be-processed part 6 in three directions: 0°, 90°, and 180°. Figure 3 As shown, a plurality of clamping through holes are provided at equal intervals along the length direction of the clamping column 2 (parallel to the Y-axis) on the clamping body.

[0031] In a further embodiment, a detection position 3 is provided at the end of the clamping column 2 away from the connecting plate 1. The detection position 3 is used for end face positioning and radial dimension control, and the geometric center of the calibration body is consistent with the center of the equipment after the equipment is installed.

[0032] The working principle of the positioning and clamping device for customized planting bases and accessories is as follows: When clamping the base to be processed, the positioning end 5 of the base is inserted into the positioning hole 7. The locking screw is continuously screwed into the locking threaded hole 4, and further screwed into the fixing threaded hole 8 of the positioning end 5 of the base. The base to be processed is threadedly fixed to the clamping body by the locking screw. After processing, the locking screw is unscrewed, and the processed base is removed from the clamping body. The clamping and fixing of the base to be processed to the clamping body by the locking screw makes it difficult for the base to be processed to loosen radially and axially between the base to be processed and the clamping body, thus ensuring processing accuracy.

[0033] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
