Description

Technical Field

[0001] This utility model belongs to the field of attachment denture technology, and specifically relates to an attachment denture. Background Technology

[0002] Attachment dentures are removable dentures with attachments as the main fixation method. They usually consist of two parts: an abutment tooth or implant and a removable denture. They are mainly used to restore missing teeth, fixed dentures, and free teeth at the ends of the teeth.

[0003] For example, Chinese utility model patent CN218075284U discloses a ball-cap type precision attachment denture. This application includes a first fixing frame and a buckle. The buckle is installed on the right side of the first fixing frame, and the buckle is fixedly connected to the first fixing frame. This utility model overcomes the shortcomings of the prior art. By setting a two-section fixing frame, the user can connect the two sections of the fixing frame with the buckle, so that the denture can be freely replaced at one end during use without replacing the entire denture, reducing the cost of use. Moreover, when connecting the denture, the installation of the denture is completed by inserting the ball into the ball cap. Furthermore, the denture is equipped with a limiting knob at one end of the ball cap. Inserting the limiting knob into the ball can fix the ball cap a second time, preventing the denture from loosening during use due to an insecure connection, improving the connection's firmness, and benefiting practical use.

[0004] This application uses a limiting knob to lock and fix the ball cap and the ball to ensure the connection of the fixed denture. However, as can be seen from the description in the instruction manual and the accompanying drawings, the application does not describe the specific assembly method and state of the denture body and the ball cap. Moreover, multiple denture bodies are fixedly assembled on top of the ball cap. This means that when a single denture body needs to be disassembled and replaced, multiple denture bodies need to be disassembled as a whole and reassembled. This process is not only cumbersome and complicated, but also prone to loosening of the denture bodies in other positions due to repeated disassembly and reassembly. This makes the convenience and reliability of disassembly and replacement of this type of attachment denture poor.

[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide an attachment denture.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Several anti-loosening bolts 6 are threaded into the anti-loosening bolt holes. The anti-loosening bolt holes facilitate the assembly and positioning of the anti-loosening bolts 6, thereby facilitating the locking and fixing of the denture fixation body 9 through the anti-loosening bolts 6.

[0038] like Figure 2 As shown, a denture fixation body 9 is integrally formed below each of the denture bodies 5. The denture fixation body 9 is inserted and assembled into an insertion positioning groove, and one end of each of the anti-dislodgement bolts 6 located in the insertion positioning groove is in contact with the outer surface of the denture fixation body 9. The denture body 5 is assembled and limited by the cooperation between the denture fixation body 9 and the insertion positioning groove. At the same time, the denture fixation body 9 can be locked and fixed by the mutual release of the anti-dislodgement bolts 6 and the denture fixation body 9, thereby playing a role in preventing the denture body 5 from dislodging.

[0039] like Figures 1 to 2 As shown, one end of the denture assembly frame 4 is integrally formed with an anti-dislodgement buckle 7. The anti-dislodgement buckle 7 can be used to prevent and limit the dislodgement of several denture bodies 5 by fitting them against the teeth in the user's mouth.

[0040] Specifically, in practical applications, the dimensions of the anti-detachment buckle 7 are matched with the dimensions of the user's teeth in their mouth.

[0041] In practical use, the implant 1 is implanted into the missing tooth area in the user's mouth using a threaded connection. The ball cap 3 is then fitted onto the assembly table 101 by engaging the positioning groove at the bottom of the ball 2 and the cap 301. Subsequently, the connecting screw 302 is connected to the denture assembly frame 4 using a threaded connection. The denture assembly frame 4 is further positioned by using the anti-dislodgement clip 7 to fit against the remaining teeth in the mouth. During the connection process, the connecting screw 302 can be connected to the assembly thread groove below the denture assembly frame 4 by rotating the cap 301 around the ball 2.

[0042] After the denture assembly frame 4 is assembled, the ball 2 and the cap 301 can be locked and fixed by installing the fixing screws 8 into the locking threaded holes. Then, several denture bodies 5 can be inserted and assembled on top of the denture assembly frame 4 by cooperating with the denture fixing body 9 and the insertion positioning groove. By installing several anti-dislodgement bolts 6, the anti-dislodgement bolts 6 lock and fix the denture fixing body 9, thereby preventing the denture body 5 from falling out. Similarly, when it is necessary to disassemble and replace the denture body 5, the individual denture body 5 can be disassembled and replaced independently by removing the anti-dislodgement bolts 6, which simplifies the convenience and reliability of disassembling and replacing attached dentures.
