Description

Technical Field

[0001] This application relates to the field of implant denture manufacturing, and particularly to a denture fixing member and a denture. Background Art

[0002] As an important part of the oral restoration field, the design and technical level of denture fixing members are directly related to the stability of dentures and the user experience of patients. With the continuous progress of oral medicine technology, the requirements for denture fixing members are also getting higher and higher. This requires that the fixing members not only have good retention force, but also possess characteristics such as biocompatibility, corrosion resistance, and easy cleaning. Existing dentures usually use an integrated fixing method, which cannot be disassembled, making it difficult to clean the gaps between dentures.

[0003] For example, in the patent application No. CN202021833320.2, a denture includes a denture base, on which multiple denture bodies are provided, and multiple grooves for installing individual denture bodies are provided on the denture base. It is characterized in that: a fixing groove is provided at the abutting position of adjacent denture bodies, and an elastic sheet is provided in the fixing groove. The following deficiencies exist in the actual use of the above device:

[0004] This device forms an integral fixation between the denture body and the installation post to achieve the effect of stabilizing the denture. However, after the denture body and the installation post are fixed, as people use it, dirt will remain in the gaps of the denture body. The integrally fixed denture body cannot be disassembled, which is very troublesome when cleaning the gaps. Moreover, over time, the remaining dirt will cause corrosion damage to the denture body itself. Utility Model Content

[0005] In order to improve the problems of difficult cleaning and inconvenient maintenance, this application provides a denture fixing member and a denture.

[0006] The denture fixing member and denture provided by this application adopt the following technical solutions:

[0007] A denture fixing member and a denture include a fixed dental pad, and a plurality of fixing mechanisms for fixing dentures are provided on the top of the fixed dental pad.

[0008] The fixing mechanism includes a fixed cylinder fixedly arranged on the top of the fixed dental pad. The fixed cylinder has a through hole inside, and a rotating rod is arranged on the inner wall of the through hole. A first clamping plate is rotatably arranged on the surface of the rotating rod, and a second clamping plate is rotatably arranged on the surface of the rotating rod on one side of the first clamping plate. A spring is connected to the opposite sides of the first clamping plate and the second clamping plate.

[0009] An installation groove is provided at the bottom of the fixed dental pad. Isolation pads are provided on both sides of the top of the inner wall of the installation groove, and an extrusion block for installation and fixation is elastically arranged at the bottom of the installation groove inside the isolation pads.

[0010] By adopting the above technical solution, the first clamping plate and the second clamping plate are respectively inserted through the fixed cylinder and the subsequent tooth body to form a clamping fixation. At the same time, the spring is bent under the downward pressure, so as to apply a pulling force to the opposite sides of the first clamping plate and the second clamping plate, so that the first clamping plate and the second clamping plate are retracted into the fixed cylinder, thus canceling the clamping of the tooth body and forming the movable disassembly of the tooth body, which is convenient for personnel to clean up.

[0011] Preferably, positioning grooves are provided at the positions of the fixed dental pad corresponding to the plurality of fixed cylinders. A connection hole is provided at the bottom of the positioning groove at the position of the through hole of the fixed cylinder, and the connection hole penetrates through the fixed dental pad and communicates with the installation groove.

[0012] By adopting the above technical solution, the connection hole penetrates through the fixed dental pad to form the communication between the fixed cylinder and the installation groove, reserving space for the extrusion spring structure to extend into the installation groove.

[0013] Preferably, movable openings are provided on the outer surface of the fixed cylinder at the positions of the first clamping plate and the second clamping plate. The two movable openings communicate with the inside of the fixed cylinder and are respectively movably inserted with the first clamping plate and the second clamping plate.

[0014] By adopting the above technical solution, the movable openings are inserted with the first clamping plate and the second clamping plate, thus reserving movable space for the rotation of the first clamping plate and the second clamping plate, so that the first clamping plate and the second clamping plate extend outwards to form a clamping and fixing effect with the clamping structure.

[0015] Preferably, a pulling plate is arranged around the surface of the spring, and the bottom of the pulling plate is inserted through the connection hole and located in the installation groove.

[0016] By adopting the above technical solution, the pulling plate surrounds the spring, which is convenient for applying a pulling force to the spring, and the bottom of the pulling plate extends into the installation groove to be connected with the subsequent pulling force generating structure.

[0017] Preferably, insertion openings are provided on both sides of the surface of the pulling plate, and the inner walls of the insertion openings are movably inserted with the rotating rods.

[0018] By adopting the above technical solution, the insertion openings provided on both sides of the pulling plate are inserted with the rotating rods. When the pulling plate moves downwards, the insertion openings descend synchronously and keep in contact with the rotating rods, preventing the pulling plate from being misaligned with the rotating rods when descending.

[0019] Preferably, a pressure plate is movably inserted between two isolation pads at the top of the installation groove, and the top of the pressure plate is fixedly connected with the pulling plate.

[0020] By adopting the above technical solution, the pressure plate is pressed downwards under the pressure to pull the pulling plate, so that the pulling plate moves downwards synchronously, thus applying a pulling force to the spring to form a downward bend.

[0021] Preferably, both ends of the side surface of the fixed tooth pad are located at the top of the installation groove and have force grooves, the two force grooves are plugged into the two sides of the end of the pressure plate, side grooves are provided on both sides of the bottom of the installation groove, and the inner walls of the two side grooves are elastically connected to the two extrusion blocks one by one through torsion springs.

[0022] By adopting the above technical solution, the force groove is clamped with both ends of the pressure plate, thereby providing a force point for people to apply pressure to the pressure plate. At the same time, torsion springs are provided on the inner walls of the two side grooves, so that the extrusion block is located in the side groove and moves elastically, thereby fixing the fixed tooth pad as a whole to the person's mouth, thereby improving the comfort of use.

[0023] A denture includes the above-mentioned denture fixing part, including a tooth body, a socket is provided at the bottom of the tooth body at the position of the fixing tube, the inner wall of the socket is plugged into the fixing tube, and the inner wall of the socket is provided with a clamping groove at the position of the clamping plate 1 and the clamping plate 2, and the inner walls of the two clamping grooves are respectively plugged and fixed to the clamping plate 1 and the clamping plate 2.

[0024] By adopting the above technical solution, the tooth body is limited when inserted into the positioning groove, so that the inner wall of the socket is inserted into the fixed tube to form a horizontal fixation. At the same time, the clamping groove inside the tooth body provides a movable space for the clamping plate 1 and the clamping plate 2, so that the clamping plate 1 and the clamping plate 2 are clamped and fixed with the clamping groove when they are rotated and unfolded.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The first and second clamping plates are used to form a clamping connection with the clamping groove, so that the tooth body is fixed to the fixed tooth pad as a whole. At the same time, pressure is applied to the pressure plate, thereby driving the pull plate to squeeze the spring and recovering the first and second clamping plates into the fixed cylinder, thereby canceling the fixation of the tooth body and putting the tooth body in a movable disassembly state. The operation is simple and it is convenient for personnel to disassemble single or multiple teeth, facilitate cleaning and maintenance, and prevent residual dirt from causing problems.

[0027] 2. By inserting the fixed bite pad into the person's mouth, the inclined surfaces of the two extrusion blocks are in contact with the gums of the person and continuous pressure is applied to fix it. The inclined surfaces of the two extrusion blocks fit the gum part, and the two isolation pads provide soft cushioning for the gums, thereby preventing the gums from directly contacting the fixed bite pad and improving the comfort of use.

[0036] The following further elaborates on the present application in conjunction with the attached Figure 1 - Figure 5 to make a more detailed description of the present application.

[0037] The embodiment of the present application discloses a denture fixing member and a denture.

[0038] Embodiment 1

[0039] Referring to Figure 1 , Figure 2 , a denture fixing member includes a fixed dental pad 1. A plurality of positioning grooves 4 are opened inwardly at the top of the fixed dental pad 1, and a connecting hole 5 is opened at the center of the bottom of each positioning groove 4. The bottoms of the plurality of connecting holes 5 all penetrate through the bottom of the fixed dental pad 1, and a U-shaped mounting groove 6 is opened at the penetrating opening of the connecting hole 5. The mounting groove 6 surrounds the bottom of the entire fixed dental pad 1 to form a through groove. At the same time, side grooves 7 are opened inwardly on both sides of the bottom of the mounting groove 6. Torsion springs are fixedly provided on the surfaces of the two side grooves 7 corresponding to the plurality of connecting holes 5. On the opposite sides of the two rows of torsion springs, extrusion blocks 10 are fixedly connected. The extrusion blocks 10 are integrally trapezoidal and inclined downward, and the extrusion blocks 10 are made of silicone rubber material.

[0040] It should be noted that the fixed dental pad 1 is integrally arc-shaped, and the arc length can be adjusted according to the oral cavity size of the person. The fixed dental pad 1 is made of resin material, having good formability and softness, thereby improving the use comfort.

[0041] The bottom of the fixed dental pad 1 is inserted into the gingival part of the oral cavity of a person through the installation groove 6, so that the gingival part abuts against the two extrusion blocks 10, so that the two extrusion blocks 10 are respectively pressed into along the two side grooves 7, so as to extrude the torsion springs in the side grooves 7. When the gingival part is inserted to the top of the installation groove 6, the two torsion springs continuously apply a thrust to the two extrusion blocks 10, so as to form a clamping force on the gingival part, thus completing the installation.

[0042] Refer to Figure 1 , Figure 3 , Figure 5 , a fixing mechanism 3 is arranged in each of the plurality of positioning grooves 4. The fixing mechanism 3 includes a fixing cylinder 31 fixed on the surface of the positioning groove 4 at the connection hole 5. The fixing cylinder 31 is integrally cylindrical, and a through hole is opened in the middle of the fixing cylinder 31. The through hole of the fixing cylinder 31 has the same width as the connection hole 5 and is centered. A rotating rod 34 is fixed in the middle of the inner wall of the through hole of the fixing cylinder 31. A first clamping plate 33 is rotatably connected to the surface of the rotating rod 34. The first clamping plate 33 is integrally L-shaped. A second clamping plate 35 is rotatably connected to the surface of the rotating rod 34 on the other side of the first clamping plate 33. The second clamping plate 35 is L-shaped. A spring 36 is fixed on the opposite side surfaces of the first clamping plate 33 and the second clamping plate 35. A pull plate 37 is circumferentially abutted against the surface of the spring 36, and the pull plate 37 is integrally U-shaped. The U-shaped ends of the pull plate 37 pass through the connection hole 5 and are located in the installation groove 6.

[0043] It should be noted that the L-shaped protrusions at the tops of the first clamping plate 33 and the second clamping plate 35 are both provided with movable openings 32 penetrating through the fixing cylinder 31, and the L-shaped protrusions of the first clamping plate 33 and the second clamping plate 35 both pass through the movable openings 32 and are located outside the fixing cylinder 31. At the same time, through holes 38 are opened at both ends of the side of the pull plate 37, and the inner walls of the through holes 38 are movably abutted against the rotating rod 34.

[0044] The spring 36 is normally in an extended state, so as to continuously apply a thrust to the first clamping plate 33 and the second clamping plate 35, so that the bottoms of the first clamping plate 33 and the second clamping plate 35 rotate around the rotating rod 34, and the tops rotate, so that the L-shaped protrusion parts penetrate out from the two movable openings 32, and the L-shaped protrusion parts of the first clamping plate 33 and the second clamping plate 35 are located outside the fixing cylinder 31 to form a clamping connection. At the same time, the pull plate 37 moves downward under the action of the pulling force, and the top of the pull plate 37 applies a downward pressure to the spring 36, so that the spring 36 deforms and contracts. When the spring 36 contracts, it drives the first clamping plate 33 and the second clamping plate 35 to rotate towards each other around the rotating rod 34, so as to withdraw into the fixing cylinder 31 and cancel the clamping state.

[0045] Refer to Figure 1 , Figure 2 , Figure 3, a fixed dental pad 1 is movably provided with an annular pressure plate 8 in the middle of the installation groove 6, and the upper end surface of the pressure plate 8 is fixedly connected to the bottoms of the U-shaped two ends of the pull plate 37. Convex blocks are arranged at both ends of the pressure plate 8. Force application grooves 11 are inwardly opened at the positions of the convex blocks of the pressure plate 8 on the fixed dental pad 1. The inner wall of the force application groove 11 abuts against the convex blocks of the pressure plate 8, and the width of the groove of the force application groove 11 is greater than one-third of the convex blocks of the pressure plate 8 (as Figure 2 shown), isolation pads 9 are fixedly bonded to both ends of the pressure plate 8 on the surface of the installation groove 6. The isolation pads 9 are made of silicone rubber material to improve softness.

[0046] It should be noted that the surface of the isolation pad 9, the bottom surface of the pressure plate 8, and the surface of the extrusion block 10 are integrally U-shaped and horizontally consistent (as Figure 2 shown), keeping the bottom of the fixed dental pad 1 smooth, so as to facilitate the installation and use by personnel and improve comfort.

[0047] The two force application grooves 11 apply downward pressure to the raised parts at both ends of the pressure plate 8, causing the pressure plate 8 to move downward. The pressure plate 8 drives the bottom of the pull plate 37 to move downward synchronously, providing power for the contraction of the first clamping plate 33 and the second clamping plate 35. And the operation is simple. At the same time, as the personnel insert the fixed dental pad 1 into the gum part of the personnel, the two isolation pads 9 abut against the top of the gum, forming a buffer to prevent damage caused by the direct contact of the personnel's gum with the fixed dental pad 1.

[0048] The implementation principle of an implant fixing member in an embodiment of the present application is as follows: when using this fixing member, the fixed dental pad 1 is placed in the oral cavity of the personnel and pressed downward in a state where the installation groove 6 is aligned with the gum part of the personnel. As the fixed dental pad 1 is pressed downward, the gum part abuts against the inclined surfaces of the two extrusion blocks 10 and continues to be pressed in, so as to squeeze the two extrusion blocks 10 into the side grooves 7. When the gum part is completely inserted into the installation groove 6, the torsion springs in the side grooves 7 push the two extrusion blocks 10 to continuously apply a thrust force to the gum, forming a clamping force to fix the fixed dental pad 1 in the oral cavity of the personnel;

[0049] At the same time, the first clamping plate 33 and the second clamping plate 35 are continuously in an unfolded state outside the fixed cylinder 31, so that the L-shaped protrusions at the tops of the first clamping plate 33 and the second clamping plate 35 are clamped and fixed to the denture structure;

[0050] When the fixed dental pad 1 is taken out of the oral cavity, the personnel apply downward pressure to the pressure plate 8 by exerting force through the pores in the two force application grooves 11. The pressure plate 8 drives the pull plate 37 to press downward, so that the top of the pull plate 37 squeezes the spring 36. The spring 36 is squeezed and deformed and thus contracts as a whole. As the spring 36 contracts, a pulling force is applied to the first clamping plate 33 and the second clamping plate 35, so that the parts of the first clamping plate 33 and the second clamping plate 35 outside the fixed cylinder 31 are retracted into the fixed cylinder 31, thereby canceling the clamping state and facilitating the disassembly of the denture structure, so as to complete the cleaning.

[0051] Example 2

[0052] Refer to Figure 3 、 Figure 4 In this example, the difference from Example 1 is that a denture includes a tooth body 2. The outer shape of the tooth body 2 is the same as that of a tooth. The outer surface of the tooth body 2 is inserted downward from the positioning groove 4 and abuts against the upper end surface of the fixed dental pad 1. A jack 12 is provided at the position of the bottom surface of the tooth body 2 where the fixed cylinder 31 is located, and the width of the jack 12 is the same as the width of the fixed cylinder 31. The surface of the fixed cylinder 31 is inserted into the jack 12. At the same time, clamping grooves 13 are provided on the inner wall of the jack 12 at the positions where the first clamping plate 33 and the second clamping plate 35 protrude from the fixed cylinder 31, and the widths of the two clamping grooves 13 are greater than the widths of the L-shaped protrusions of the first clamping plate 33 and the second clamping plate 35, so as to reserve a moving gap.

[0053] The implementation principle of Example 2 is as follows: Before the fixed dental pad 1 is placed in a person's oral cavity, the tooth body 2 is inserted into the positioning groove 4 from top to bottom. At the same time, as the tooth body 2 is inserted, the surface of the fixed cylinder 31 is synchronously inserted into the jack 12. As the fixed cylinder 31 enters the jack 12, the inner wall of the jack 12 squeezes the inclined surfaces of the L-shaped protrusions of the first clamping plate 33 and the second clamping plate 35, so as to squeeze the first clamping plate 33 and the second clamping plate 35 into the fixed cylinder 31. When the top of the fixed cylinder 31 abuts against the end of the jack 12, the clamping grooves 13 are aligned with the two movable openings 32, so that the front of the two movable openings 32 is in a hollow state. The squeezing force applied to the first clamping plate 33 and the second clamping plate 35 is cancelled. The first clamping plate 33 and the second clamping plate 35 lose the squeezing force and are extruded outward from the movable openings 32 by the resilience of the spring 36, and finally are respectively clamped with the two clamping grooves 13 to form the overall fixation of the tooth body 2 and the fixed dental pad 1, thus completing the assembly.

[0054] The above are all the preferred embodiments of this application. The protection scope of this application is not limited hereby. Therefore, any equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
