Description

Technical Field

[0001] The present application relates to the technical field of removable denture installation, and in particular to an adjustable removable denture installation structure. Background Art

[0002] Removable dentures, also known as removable dentures, include both partial and complete dentures. They utilize the remaining natural teeth, the underlying mucosa, and bone tissue for support, and are retained by the denture's retainers and base. Artificial teeth restore the form and function of missing teeth, while base materials restore the morphology of the alveolar ridge, jawbone, and surrounding soft tissues. Patients can remove and wear these prostheses themselves.

[0003] An existing Chinese patent with publication number CN209004274U discloses a removable denture mounting structure, comprising: a tooth seat placed on a gum to partially wrap the gum, a plurality of dentures detachably mounted on the tooth seat, a tooth clasp mounted on the inner side of a natural tooth adjacent to the tooth seat, an insert ring fixed to the side of the tooth clasp close to the tooth seat, and an insert column fixed to the bottom of the tooth seat to engage with the insert ring.

[0004] With respect to the above-mentioned related technologies, the inventors found that there are at least the following problems in the technology: when fixing the denture, the denture is assembled by means of an embedded ring and an embedded post. Due to the lack of a limiting structure between the embedded ring and the embedded post, the stability of the denture after installation is poor and the risk of falling off is high. Utility Model Content

[0005] In order to improve the problem of poor stability and high risk of falling off of dentures after installation, the present application provides an adjustable removable denture installation structure.

[0006] The present application provides an adjustable removable denture installation structure that adopts the following technical solutions:

[0007] A movable adjustable denture mounting structure comprises a tooth seat pre-installed on a gum and a denture mounted on the tooth seat, the bottom of the tooth seat being integrally provided with an embedding portion, the gum being provided with an embedding groove for matching with the embedding portion, a screw tube being fixedly implanted inside the embedding groove, the bottom of the embedding portion being provided with a circular groove matching with the screw tube, the top of the tooth seat being provided with a connecting groove, the bottom of the connecting groove being plugged with a connecting screw, the connecting screw passing through the embedding portion and extending into the screw tube to be threadedly connected with the screw tube, the bottom of the denture being integrally provided with a connecting block matching with the connecting groove, both sides of the connecting block being provided with limiting grooves, both sides of the tooth seat being provided with a cavity, and a limiting component being provided in the cavity.

[0008] By adopting the above technical solution, the tooth seat can be pre-installed on the gum before installing the denture. The specific method is: insert the embedded part of the tooth seat into the adapted embedded groove on the gum, and at the same time insert the screw into the circular groove, and then insert the connecting screw along the connecting groove, and use a tool to rotate the connecting screw so that the connecting screw is screwed into the screw tube to fix the tooth seat; when installing the denture, insert the connecting block into the connecting groove. When the connecting block completely enters the connecting groove, the bottom surface of the denture is pressed against the top surface of the tooth seat, and at the same time the limit assembly limits and fixes the denture, thereby improving the stability of the denture installation and reducing the risk of falling off.

[0009] Preferably, a gasket is abutted between the connecting screw and the inner bottom wall of the connecting groove.

[0010] By adopting the above technical solution, the contact area between the connecting screw and the bottom wall of the connecting groove can be increased, the stress on the bottom wall of the connecting groove can be dispersed, and the connection of the connecting screw can be made more stable.

[0011] Preferably, a positioning groove is provided at the edge of the top of the tooth seat, and a positioning rod adapted to the positioning groove is integrally provided at the edge of the bottom of the denture.

[0012] By adopting the above technical solution, when installing the denture, the positioning rod can be aligned with the positioning groove and inserted, which can quickly align and position the denture, making it easier to install the denture.

[0013] Preferably, a magnet is fixedly connected to the interior of the connecting groove, and an iron sheet is embedded and installed at the bottom of the connecting block.

[0014] By adopting the above technical solution, when the connecting block is inserted into the connecting slot, the magnet can exert a magnetic attraction on the iron sheet, so that the connecting block can quickly enter the connecting slot.

[0016] By adopting the above technical solution, when installing the denture, the connecting block is inserted into the connecting groove. When the connecting block completely enters the connecting groove, the bottom surface of the denture is pressed against the top surface of the tooth seat, and at the same time, the limit rod is facing the limit groove. At this time, the limit rod will be pushed into the limit groove under the action of the elastic force of the spring, which can limit and fix the denture, improve the stability of the denture installation, and reduce the risk of falling off; when removing the denture, you only need to press the pressing rod so that the pressing rod drives the limit rod out of the limit groove through the connecting rod, and the denture can be removed, which ensures stability while still being convenient for disassembly and assembly.

[0017] Preferably, an inclined surface is provided on one end of the limiting rod facing the opening of the connecting groove.

[0018] By adopting the above technical solution, the connecting block can be inserted into the connecting groove more smoothly.

[0019] Preferably, the limiting rod and the pressing rod are both provided with a guide block at one end close to the spring, and both ends of the connecting rod are provided with a guide groove, and the guide block is slidably connected in the guide groove.

[0020] By adopting the above technical solution, the limiting rod and the pressing rod can be linked with the connecting rod.

[0021] Preferably, a sealing ring is fixedly sleeved on one end of the pressing rod away from the spring.

[0022] By adopting the above technical solution and providing the sealing ring, the sealing performance at the pressing rod can be improved.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When installing the denture, use the limit assembly to insert the connecting block into the connecting groove. When the connecting block is fully inserted into the connecting groove, the bottom surface of the denture is pressed against the top surface of the tooth seat, and the limit rod is facing the limit groove. At this time, the limit rod is pushed into the limit groove under the elastic force of the spring, which can limit and fix the denture, improve the stability of the denture installation, and reduce the risk of falling off. When removing the denture, you only need to press the pressing rod, so that the pressing rod drives the limit rod out of the limit groove through the connecting rod, and the denture can be removed. It ensures stability while still being convenient for disassembly and assembly.

[0025] 2. With the help of the cooperation between the positioning groove and the positioning rod, when installing the denture, the positioning rod can be aligned with the positioning groove and inserted, which can quickly align and position the denture, making it easier to install the denture;

[0026] 3. Through the arrangement of the magnet and the iron sheet, when the connecting block is inserted into the connecting slot, the magnet can exert a magnetic attraction on the iron sheet, so that the connecting block can quickly enter the connecting slot. BRIEF DESCRIPTION OF THE DRAWINGS
