Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis technology, and in particular to a removable partial denture. Background Technology

[0002] Removable partial dentures are dentures configured for insertion into and removal from the mouth. For functional and / or aesthetic reasons, they are designed to replace missing teeth. Such partial dentures typically consist of one or more prosthetic teeth attached to a base that provides artificial gingiva for the prosthetic teeth. The shape and color of the artificial gingiva can mimic the patient's natural gingiva. Removable partial dentures are designed to fit into and be removed from the mouth, conform to the natural geometry of the patient's mouth, and provide sufficient stability to ensure their structural integrity during use, such as when chewing.

[0003] Because dentures cannot be installed in a timely and smooth manner, they cannot quickly perform normal chewing and speech functions. Patients' quality of life will be greatly affected in the early stages of wearing dentures, which may lead to unbalanced diet and affect nutrient absorption. Utility Model Content

[0023] Reference Figure 1-4This utility model discloses a removable partial denture, comprising: a denture 1, a fixing plate 18 on the lower surface of the denture 1, the fixing plate 18 providing support and a fixed base for the denture 1, ensuring a stable position of the denture 1 in the oral cavity; a positioning post 15 fixedly connected to the inner surface of the denture 1, the positioning post 15 determining the installation position of the support post 11, ensuring accurate installation and stability of the support structure; a support post 11 threadedly connected to the inner surface of the positioning post 15, the support post 11 being threadedly connected to the positioning post 15, allowing adjustment of its position within the positioning post 15 to adapt to different oral conditions; and the support post 11... The support column 11 has a second cross groove 16 inside, and the interior of the second cross groove 16 is connected to the upper surface of the support column 11. The second cross groove 16 can be used with tools to rotate and adjust the support column 11, making it easy to adjust the height of the support column 11. The outer surface of the support column 11 is fixedly connected to an abutment column 12, which can cooperate with the spring 14 to transmit the elastic force of the spring 14 and provide an upward buffer support force for the denture 1. The abutment column 12 has a mating groove 13 inside, and the interior of the mating groove 13 is connected to the upper surface of the abutment column 12. The mating groove 13 provides installation space for the spring 14, so that it can be stably placed and perform its function. A spring 14 is fitted inside the groove 13, and the upper surface of the spring 14 is connected to the interior of the denture 1. When the spring 14 is compressed and extended, it can buffer the pressure on the denture 1 in the oral cavity and improve wearing comfort. A rotating bearing 10 is fixedly connected to the lower surface of the support post 11. The rotating bearing 10 allows the connecting post 9 to rotate relative to the support post 11, making the denture 1 more flexible in adapting to complex oral movements. The lower surface of the rotating bearing 10 is rotatably connected to the connecting post 9, which is connected to the support post 11 through the rotating bearing 10. This allows the supporting force of the support post 11 to be transmitted to the limiting post 8, and it can rotate flexibly with oral movements. The lower surface of the connecting post 9 is fixedly connected to the limiting post 8, and the limiting post 8 is located on the lower surface of the denture 1. The limiting post 8 is used to limit the range of movement of the denture 1 in the oral cavity and ensure the stability of the denture 1 during chewing and other actions. The fixing plate 18 has an embedding groove 7 and a sliding groove 17 inside, and the interior of the embedding groove 7 and the interior of the sliding groove 17 are connected. The embedding groove 7 and the sliding groove 17 together provide a movement track for the limiting post 8 and the connecting post 9, so that they can move within a specified range. The inner surfaces of the limiting post 8 and the embedding groove 7 abut against each other, and the limiting post 8 slides in the embedding groove 7, which can prevent the denture 1 from wobbling from side to side and maintain the lateral stability of the denture 1.

[0024] The interior of the sliding groove 17 is connected to the front surface of the fixing plate 18, facilitating the insertion of the connecting post 9 from the front of the fixing plate 18 into the sliding groove 17, thus enabling the installation and removal of the denture 1. The interior of the embedding groove 7 is connected to the upper and lower surfaces of the fixing plate 18, allowing the limiting post 8 to move freely up and down within the embedding groove 7 to adapt to different pressure changes in the oral cavity. The interior of the positioning post 15 is connected to the upper surface of the denture 1, facilitating the operation and adjustment of the support post 11 inside the positioning post 15 from the upper surface of the denture 1. The outer surface of the connecting post 9 is slidably connected to the interior of the sliding groove 17, allowing the connecting post 9 to slide within the sliding groove 17, enabling fine-tuning of the denture 1 up and down for better fit to the oral tissue. The interior of the spring 14 is compatible with the interior of the mating groove 13, ensuring that the spring 14 can be securely installed within the mating groove 13 and function properly as a buffer. The inner surface of the spring 14 is sleeved with the positioning post 15, further fixing the position of the spring 14, allowing the spring 14 to function properly under compression and... During the extension process, the connection plate 18 is fixedly connected to the left and right sides of the lower surface of the fixed plate 18. The connecting block 2 is used to connect the connecting plate 6, providing a basis for the connection between the denture 1 and other parts of the oral cavity. The lower surface of the connecting block 2 is fixedly connected to the connecting plate 6. The connecting plate 6 connects the connecting block 2 to the positioning bolt 3, enhancing the stability of the connection between the denture 1 and the oral tissue. The positioning bolt 3 is slidably connected inside the connecting plate 6. The positioning bolt 3 can be adjusted in position within the connecting plate 6 to accurately fix the position of the denture 1 in the oral cavity. The positioning bolt 3 has a groove 4 inside, and the inside of the groove 4 is connected to the upper surface of the positioning bolt 3. The groove 4 is used to accommodate tools to facilitate the rotation and tightening operation of the positioning bolt 3. The lower surface of the groove 4 is provided with a first cross groove 5, and the inside of the first cross groove 5 is connected to the inside of the groove 4. The first cross groove 5, with the help of a specific tool, makes it easier to tighten or loosen the positioning bolt 3.

[0025] Working principle: Positioning bolt 3 is pre-fixed in the corresponding position inside the oral cavity. Using a tool, the positioning bolt 3 is tightened through the groove 4 and the first cross groove 5 to ensure its stability. The connecting plate 6 is passed through the fixed positioning bolt 3 and slid onto it to the appropriate position. The lower surface of the connecting plate 6 fits tightly with the positioning bolt 3, providing a foundation for the installation of the denture 1. The connecting block 2 is fixed on the left and right sides of the lower surface of the fixing plate 18, connecting the connecting block 2 to the connecting plate 6, completing the connection between the fixing plate 18 and the fixed structure inside the oral cavity. The limiting post 8 is aligned with the embedding groove 7 of the fixing plate 18. The connecting post 9 is inserted upwards from below the fixing plate 18 through the embedding groove 7 and the sliding groove 17. At this time, the rotating bearing 10 connects the support post 11 and the connecting post 9, allowing the connecting post 9 to rotate flexibly. The limiting post 8, within the embedding groove 7, restricts the lateral movement of the denture 1. The spring 14 is placed into the mating groove 13 of the abutment post 12, with the inner surface of the spring 14 sleeved on the fixed post 12. On the positioning post 15, ensure a stable installation and provide cushioning elasticity for the denture 1. Connect the support post 11 to the positioning post 15 via threads. Insert a tool into the second cross groove 16 and rotate the support post 11 according to the oral condition to adjust its height within the positioning post 15 to fit the oral environment. Install the denture 1 as a whole on the connected fixing plate 18 and support structure, ensuring that all components are tightly connected and the denture 1 is accurately positioned. During the wearing of the denture 1, the spring 14 compresses and extends to cushion the pressure inside the oral cavity. The limiting post 8 moves within the embedding groove 7 to limit the range of movement of the denture 1, ensuring the stability of the denture 1 during chewing and other actions. The connecting post 9 slides within the sliding groove 17 to achieve fine-tuning of the denture 1 up and down, conforming to the oral tissue and ensuring normal use of the denture 1. Use a tool to rotate the positioning bolt 3 in the opposite direction to unscrew it from the connecting plate 6. Then, pull out the connecting post 9 from the front surface of the fixing plate 18 to remove the denture 1 from the oral cavity for cleaning and maintenance.
