Description

Technical Field

[0001] The utility model belongs to the technical field of dental implant abutments, and more specifically, relates to an abutment system. Background Art

[0002] Dental implants are very common in modern life. In order to more firmly fix the object to be installed (object to be installed: such as a dental bridge or denture), it is usually fixed to the abutment by bonding. The object to be installed can also be fixed to the abutment by screws through threaded holes (threaded holes of the abutment). Usually, the contact surface shapes between the object to be installed and the abutment match each other. However, if the relative position of the object to be installed and the abutment is offset during installation, the shape of the object to be installed is generally modified. However, once the object to be installed is modified, it is easy to affect the strength of the object to be installed, and the object to be installed can easily be scrapped during the shape adjustment process.

[0003] The base can be referenced: Please refer to (China Utility Model Patent; Publication Number: CN219940836U; Subject Name: A Personalized Composite Base; Publication Date: 2023-11-03).

[0004] The method of fixing the abutment to the implant by screws can be referred to: (Chinese invention patent; publication number: CN117860420A; subject name: Implant system monitoring device and monitoring method; publication date: 2024-04-12).

[0005] The main functions of angled screw-retained abutments include the following:

[0006] 1. Provide a stable connection

[0007] Compared with adhesive fixation, screw fixation can provide higher stability and resistance, reducing the risk of loosening or falling off of the restoration (bridge or denture).

[0008] 2. Convenient removal and maintenance of the restoration

[0009] The design of the angled screw-retained abutment allows for easy removal and reinstallation of the restoration. This is essential for regular inspection, cleaning, and maintenance, helping to extend the life of the restoration and implant. Furthermore, if adjustments or revisions to the restoration are necessary, screw retention makes this easier to do.

[0010] 3. Improve the accuracy and adaptability of restorations

[0011] Screw-retained abutments provide precise connection positions and angles, ensuring a tight fit between the restoration and the implant. This is crucial for achieving optimal functional and aesthetic results. This precise fit minimizes micromotion and reduces the risk of peri-implant bone resorption.

[0012] 4. Provide good force conduction

[0013] Screw-retained abutments evenly transmit occlusal forces to the implant and surrounding bone, reducing stress concentrations and the risk of implant failure. By optimizing force transmission, the long-term stability and durability of the restoration and implant can be improved.

[0014] 5. Flexible design and application

[0015] Screw-retained abutments are available in a variety of designs and sizes to suit different clinical situations and prosthetic needs. For example, abutments with different angles can be selected to adjust the position and orientation of the restoration to suit the patient's occlusal relationship and aesthetic requirements.

[0041] Please also refer to Figures 1 to 4 The abutment system provided by the present invention is now described. The abutment system comprises an abutment 1, which includes a mounting hole 12 for engaging a first screw 21 secured to an implant 4, a threaded hole 13 for engaging a second screw 22 on an object 3 to be mounted, and a support plane 11 for supporting the object 3 to be mounted. The threaded hole 13 extends perpendicular to the support plane 11.

[0042] In this way, the base 1 has a mounting hole 12, and the first screw 21 can pass through the mounting hole 12 to fix the base 1 to the implant 4; the object 3 to be mounted can be threadedly connected to the threaded hole 13 by the second screw 22, so that the object 3 to be mounted can be fixed to the base 1 by the second screw 22; the object 3 to be mounted can be supported on the supporting plane 11; since the supporting plane 11 is arranged perpendicular to the extension direction of the threaded hole 13, when the second screw 22 locks the object to be mounted 3, the object to be mounted 3 can apply stress vertically to the supporting plane 11, thereby preventing the object to be mounted 3 from slipping sideways when supported on the supporting plane 11; and when the object to be mounted 3 is relatively misaligned along the supporting plane 11, the contact surface between the object to be mounted 3 and the supporting plane 11 does not change, and there is no need to modify the surface shape of the contact between the object to be mounted 3 and the supporting plane 11; in addition, when the object to be mounted 3 is relatively misaligned along the supporting plane 11, the stress direction between the object to be mounted 3 and the supporting plane 11 does not change.

[0043] In one embodiment, the object 3 to be installed is a dental bridge or a denture.

[0044] In one embodiment, an assembly hole 31 is formed on the object to be mounted 3 , and the second screw 22 passes through the assembly hole 31 and is threadedly connected to the threaded hole 13 .

[0045] In one embodiment, the bottom of the abutment 1 passes through the gum and matches the contour of the gum cuff.

[0046] In one embodiment, the mounting hole 12 extends in a straight line. In one embodiment, the threaded hole 13 extends in a straight line.

[0047] Further, see Figures 1 to 4 In one embodiment of the abutment system provided by the present invention, the angle between the opening direction of the entrance of the mounting hole 12 and the opening direction of the entrance of the threaded hole 13 is a predetermined angle; the predetermined angle is greater than zero. This reduces interference between the first screw 21 and the second screw 22.

[0048] Further, see Figures 1 to 4 As a specific embodiment of the abutment system provided by the present invention, the predetermined angle can be any acute angle. Thus, threaded holes 13 with different predetermined angles can be adapted to objects 3 of different shapes. In other words, users can select threaded holes 13 with different predetermined angles to accommodate objects 3 of different shapes as needed.

[0049] Further, see Figures 1 to 4 As a specific embodiment of the base system provided by the present invention, the threaded hole 13 is connected to the mounting hole 12. In this way, the second screw 22 in the threaded hole 13 can partially extend into the mounting hole 12 according to actual conditions.

[0050] Further, see Figures 1 to 4 As a specific embodiment of the abutment system provided by the present invention, the bottom of the abutment 1 has a polygonal prism 14 for inserting into the cavity of the implant 4. In this way, the relative rotation between the abutment 1 and the implant 4 is reduced.

[0051] In one embodiment, the implant 4 can refer to: (Chinese Utility Model Patent; Publication Number: CN220109870U; Subject Name: A Space-avoiding Structure, Implant 4 and Dental Implant Device; Publication Date: 2023-12-01).

[0052] In one embodiment, the extending direction of the mounting hole 12 is parallel to the extending direction of the polygonal prism 14 .

[0053] Further, see Figures 1 to 4 As a specific embodiment of the base system provided by the present invention, the polygonal prism 14 is a hexagonal prism. In this way, the structure is simple and easy to process.

[0054] Further, see Figures 1 to 4 As a specific embodiment of the base system provided by the present invention, a boss 15 is fixed on the support plane 11, and the threaded hole 13 is opened on the boss 15. In this way, the boss 15 can be plugged and positioned with the recessed portion on the object 3 to be installed.

[0055] In one embodiment, the boss 15 has the same shape as the recessed portion on the object 3 to be mounted.

[0056] Further, see Figures 1 to 4 As a specific embodiment of the base system provided by the present invention, the boss 15 is located in the central area of ​​the support plane 11. In this way, the boss 15 can distribute the stress to the surrounding support plane 11.

[0057] Further, see Figures 1 to 4 In one embodiment of the abutment system provided by the present invention, the boss 15 is spaced from the edge of the support plane 11 by a predetermined distance greater than zero. This prevents stress on the boss 15 from being directly transferred to the edge of the support plane 11.

[0058] Further, see Figures 1 to 4 As a specific embodiment of the base system provided by the present invention, the boss 15 can be located at any position on the support plane 11. In this way, the boss 15 can be set at different positions on the support plane 11 according to actual needs. That is, the user can select bosses 15 in different positions as needed to accommodate objects 3 to be mounted in different shapes.

[0059] 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 replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
