Description

Technical Field

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

[0002] Removable dentures are a common restorative method for missing or damaged teeth. They typically consist of artificial teeth, connectors, a base, and fixation. Traditional removable partial dentures generally have the fixation clamped to the teeth, which is easily exposed when the patient smiles or talks, affecting aesthetics and failing to meet the high aesthetic demands of modern patients. Furthermore, the transition area between the base and connectors is prone to stress concentration, leading to metal fatigue and even fracture failure. Summary of the Invention

[0003] To address the problems of existing technologies, this utility model provides a removable denture support.

[0004] To achieve the above objectives, this utility model employs the following technical solution: This utility model provides a removable denture framework, including a connector, a first base and a second base disposed on both sides of the connector, both the first base and the second base having multiple first through holes, the end of the first base having a first connecting part, and the end of the second base having a second connecting part. The connector, the first base, the second base, the first connecting part, and the second connecting part are integrally printed. A fixing body is rotatably disposed on the first connecting part, and the end of the fixing body away from the first connecting part is engaged with the second connecting part. The fixing body is configured to fit against the gum line when worn, and a resin buffer layer is disposed on the fixing body, or a fixing finger is disposed on the fixing body to fit against the interdental space.

[0005] Furthermore, a plurality of second through holes are provided on the fixing body on which the resin buffer layer is provided.

[0006] Furthermore, the inner surface of the resin buffer layer is a concave structure adapted to the human gum area, and the outer surface is a convex structure that protrudes outward.

[0007] Furthermore, the fixing body is provided with a slot on the side near the second connecting part, and the second connecting part is provided with a snap-fit ​​part that matches the slot.

[0008] Furthermore, a force-applying part is provided on the edge of the fixing body, and the force-applying part is located on the side of the slot away from the rotational connection position of the fixing body.

[0009] Furthermore, the end of the first connecting part is provided with a shaft hole, and the fixed body is provided with two supporting ears opposite each other at one end near the first connecting part. The end of the first connecting part is located between the two supporting ears and is rotatably connected to the supporting ears through a rotating shaft passing through the shaft hole.

[0010] Furthermore, the thickness of the first base and the second base is less than the thickness of the connector.

[0011] Furthermore, the first base, the second base, and the connecting body are provided with misaligned first and second grooves on both sides along the thickness direction.

[0012] Furthermore, the second groove located on the gingival side is closer to the connector than the first groove.

[0013] Compared with the prior art, the advantages of this utility model are as follows: One embodiment of this utility model involves covering the outer periphery of the fixation body with a resin buffer layer and configuring it to fit snugly against the gum area when worn. On the one hand, the resin buffer layer increases the contact area to disperse occlusal pressure, improve wearing comfort, and avoid local pressure. On the other hand, the resin buffer layer, with its color and shape similar to the gums, completely conceals the fixation body when worn, achieving an aesthetic concealment effect and effectively avoiding the visual exposure of metal components.

[0014] Another embodiment of this utility model provides a fixing finger on the fixation body that can fit closely to the user's tooth gap. The mechanical interlocking structure formed by the fixing finger and the proximal surface of the natural tooth provides a reliable retention force to resist horizontal displacement of the removable denture framework, thereby significantly enhancing the stability of the denture framework in functional movement.

[0015] The thickness of the first base and the second base of this invention is less than the thickness of the connector, so that the surface of the resin gingiva formed on the first base and the second base can be flush with the surface of the connector.

[0016] The first base, the second base, and the connector of this invention have misaligned first and second grooves formed on both sides along the thickness direction, which avoids the formation of a continuous weak line at the component connection. This effectively interrupts and redistributes the stress flow generated by the occlusal force in the structural transition zone, avoids stress concentration, and thus significantly improves the structural fatigue strength and long-term reliability of the denture framework.

[0027] like Figure 1-7 As shown, this utility model provides a removable denture framework, including a connector 1, a first base 2 and a second base 3 disposed on both sides of the connector 1. The first base 2 and the second base 3 are each provided with a plurality of first through holes 4. The end of the first base 2 is provided with a first connecting part 5, and the end of the second base 3 is provided with a second connecting part 6. The connector 1, the first base 2, the second base 3, the first connecting part 5, and the second connecting part 6 are made of metal and are integrally printed by a 3D printer. A fixing body 7 is rotatably disposed on the first connecting part 5. The end of the fixing body 7 away from the first connecting part 5 is engaged with the second connecting part 6. The fixing body 7 is configured to fit against the gum area when worn, and a resin buffer layer 8 is provided on the fixing body 7, or a fixing finger 72 is provided on the fixing body 7 to fit against the interdental space.

[0028] Specifically, such as Figure 1 , Figure 6 As shown, this embodiment covers the periphery of the fixation body 7 with a resin buffer layer 8 and is configured to fit the gum area when worn. On the one hand, the resin buffer layer 8 increases the contact area to disperse occlusal pressure, improve wearing comfort and avoid local pressure; on the other hand, the resin buffer layer 8, with its color and shape similar to the gum, completely covers the fixation body 7 when worn, achieving an aesthetic concealment effect and effectively avoiding the visual exposure of metal parts.

[0029] like Figure 7 As shown, in this embodiment, by providing a fixing finger 72 on the fixation body 7 that can fit closely to the user's tooth gap, and utilizing the mechanical interlocking structure formed by the fixing finger 72 and the proximal surface of the natural tooth, a reliable retention force is provided for the removable denture framework to resist horizontal displacement, thereby significantly enhancing the stability of the denture framework in functional movement.

[0030] like Figure 1 , Figure 3 As shown, in some embodiments, a plurality of second through holes 71 are provided on the fixing body 7 on which the resin buffer layer 8 is disposed. This allows the resin buffer layer 8 to be embedded in and pass through the second through holes 71 during molding, thereby forming a strong mechanical interlocking structure between the resin buffer layer 8 and the fixing body 7, effectively preventing peeling or relative displacement between the two due to long-term use or stress fatigue.

[0031] In some embodiments, the inner surface of the resin buffer layer 8 is a concave structure adapted to the human gum area, and its outer surface is a convex structure protruding outwards. This structure allows the inner surface of the resin buffer layer 8 to increase the contact area with the gingival mucosa to optimize pressure distribution, thereby improving wearing comfort and overall denture stability.

[0032] like Figure 2 , Figure 3 As shown, in some embodiments, the fixing body 7 is provided with a slot 73 on the side near the second connecting part 6, and the second connecting part 6 is provided with a snap-fit ​​part 61 that is adapted to the slot 73.

[0033] like Figure 3 As shown, in some embodiments, the edge of the fixing body 7 is provided with a force-applying part 74, which is located on the side of the slot 73 away from the rotational connection position of the fixing body 7, so as to facilitate the opening of the fixing body 7.

[0034] like Figures 2-4 As shown, in some embodiments, the end of the first connecting part 5 is provided with a shaft hole 51, and the fixing body 7 is provided with two supporting ears, namely a first supporting ear 75 and a second supporting ear 76, at one end near the first connecting part 5. The end of the first connecting part 5 is located between the two supporting ears and is rotatably connected to the supporting ears through a rotating shaft passing through the shaft hole 51.

[0035] In some embodiments, the thickness of the first base plate 2 and the second base plate 3 is less than the thickness of the connector 1. This is so that the surface of the resin gingiva formed on the first base plate 2 and the second base plate 3 is flush with the surface of the connector 1.

[0036] like Figure 5 As shown, preferably, the first base plate 2, the second base plate 3, and the connecting body 1 are provided with staggered first grooves 11 and second grooves 12 on both sides along the thickness direction. The staggered design of the first grooves 11 and second grooves 12 avoids the formation of a continuous weak line at the component connection, effectively interrupts and redistributes the stress flow generated by the occlusal force in the structural transition zone, avoids stress concentration, and thus significantly improves the structural fatigue strength and long-term reliability of the denture framework.

[0037] Preferably, the second groove 12 located on the gingival side is closer to the connector 1 than the first groove 11, which optimizes the overall mechanical transmission path of the denture framework and enhances its ability to resist fatigue fracture.

[0038] Those skilled in the art should understand that the specific embodiments described above are merely examples and not limitations. Various modifications, combinations, partial combinations, and substitutions can be made to the embodiments of this utility model according to design requirements and other factors, as long as they are within the scope of the appended claims or their equivalents, and thus fall within the scope of the rights to be protected by this utility model.
