Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of oral implantation, and in particular relates to a dental implant bridge abutment assembly. Background Art
[0002] In the field of oral implant restoration, the dental implant bridge abutment assembly is the key structure connecting the implant and the upper restoration. Its stability and reliability directly affect the long-term effect of implant restoration. Currently, the implant, abutment and screw are generally connected by screw extrusion fixation. This method uses the axial force generated by tightening the screw to make the abutment and implant fit tightly, achieving mechanical retention.
[0003] However, the existing technology has obvious defects. Since the screws only play a mechanical fastening role, they cannot effectively measure and control the depth of the extrusion force between the abutment and the implant. During actual operation, if the torque applied by the surgeon is too large and exceeds the bearing limit of the implant and abutment materials, it will cause the abutment and implant to crack, deform, etc., which will not only affect the service life of the implant restoration, but may also require a secondary surgical repair, causing physical pain and financial burden to the patient; if the torque is too small, the tight connection between the abutment and the implant cannot be guaranteed, which can easily cause micro-movement, leading to inflammation around the implant and even implant failure. Summary of the Invention
[0004] The present invention addresses the problem in the prior art that if the torque applied by the surgeon is too large, exceeding the bearing limit of the implant and abutment materials, it will cause the abutment and implant to crack, deform, etc., which will not only affect the service life of the implant restoration, but may also require a secondary surgical repair, causing physical pain and financial burden to the patient; if the torque is too small, the tight connection between the abutment and implant cannot be guaranteed, which is likely to cause micro-movement, leading to peri-implant inflammation and even implant failure. The present invention proposes the following technical solutions:

[0008] The fixed-point warning mechanism includes: a supporting structure, a ring, a base plate, a trapezoidal plate, a vertical plate, a metal bar and a striking piece;
[0009] The outside of the base is connected to a supporting structure, and a circular ring is connected above the supporting structure to provide stable support for the circular ring. A bottom plate is connected above the circular ring, and the circular ring is used to horizontally support the bottom plate. A trapezoidal plate is vertically movable above the bottom plate, so that the trapezoidal plate can move in the vertical direction (Y-axis direction). When the trapezoidal plate moves, it drives the vertical plate to move vertically (Y-axis movement), and at the same time triggers the deflection of the knocking piece. The deflection of the knocking piece drives the metal bar to deflect synchronously, and finally the knocking piece knocks on the vertical plate, and generates sound through mechanical collision, thereby realizing a fixed-point warning function.

[0011] The outer side of the support ring is connected to the inner side of the implant, and the plug-in column is connected to the top of the support ring. The support ring is used to support the plug-in column and limit the circular ring under the action of the plug-in column.

[0015] As a preferred embodiment of the above technical solution, a rectangular hole is provided at the bottom end of the vertical plate, and rounded corners are provided at the top and bottom ends of the rectangular hole close to one end face of the knocking piece. The bottom end of the knocking piece is set to be V-shaped, and the V-shaped area at the bottom end of the knocking piece is located inside the rectangular hole.

[0021] (2) It can effectively block the transmission of the screw rotation torque to the abutment, ensuring that the abutment remains stationary during the tightening process, does not rotate or deviate, and maintains the preset angle.
[0022] (3) Multiple bending parts and their internal balls surround the screw to provide uniform radial guiding force, forcing the screw to keep descending vertically, ensuring that the circumferential gap between its outer side and the inner side of the abutment is uniform throughout the entire process to prevent eccentricity.

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0033] Example 1
[0034] The present invention provides a dental implant bridge abutment assembly, such as Figures 1 to 8 As shown, it includes an implant 1, an abutment 2, a screw 3 and a fixed-point warning mechanism. The implant 1 serves as a supporting structure for the entire assembly; the abutment 2 is connected to the implant 1 and serves as a transition component connecting the implant 1 and the upper restoration; the screw 3 is connected to the abutment 2 and the implant 1 and is used to connect and fix the implant 1 and the abutment 2; the fixed-point warning mechanism includes: a supporting structure, a circular ring 6, a bottom plate 81, a trapezoidal plate 83, a vertical plate 86, a metal strip 88 and a knocking piece 89; the outside of the abutment 2 is connected to the supporting structure, and the top of the supporting structure is connected to the circular ring 6, and is The circular ring 6 provides stable support, and a base plate 81 is connected above the circular ring 6, and the circular ring 6 is used to horizontally support the base plate 81; a trapezoidal plate 83 is vertically movable above the base plate 81, so that the trapezoidal plate 83 can move in the vertical direction (Y-axis direction). When the trapezoidal plate 83 moves, it drives the vertical plate 86 to move vertically (Y-axis movement), and at the same time triggers the deflection of the knocking piece 89. The deflection of the knocking piece 89 drives the metal bar 88 to deflect synchronously, and finally the knocking piece 89 knocks on the vertical plate 86, generating sound through mechanical collision, thereby realizing the fixed-point warning function.
[0035] Since the abutment 2 is mounted on the top of the implant 1 and is fixed by squeezing with the screw 3, the screw 3 only plays a mechanical fastening role and cannot effectively measure and control the depth of the squeezing force between the abutment 2 and the implant 1. During actual operation, if the torque applied by the surgeon is too large, exceeding the bearing limit of the implant 1 and the abutment 2 materials, resulting in cracks, deformation, etc. on the abutment 2 and the implant 1, not only will the service life of the implant restoration be affected, but a secondary surgical repair may also be required, causing physical pain and financial burden to the patient; if the torque is too small, the tight connection between the abutment 2 and the implant 1 cannot be guaranteed, which can easily cause micro-movement, leading to inflammation around the implant 1, or even implant failure.
[0036] For this purpose, a fixed-point warning mechanism is set up. When the abutment 2 and the implant 1 are installed to the predetermined position, a sound warning is issued by the fixed-point warning mechanism to control the squeezing force between the two to avoid excessive or insufficient torque. Excessive torque can easily cause the abutment 2 and the implant 1 to rupture and deform, increasing the risk of secondary surgery; excessive torque can cause micro-movement and inflammation, leading to implant failure. The sound warning can intuitively remind the doctor to install the device in place, reduce structural damage and postoperative complications caused by improper operation, improve the success rate of implantation, reduce the patient's physical pain and economic burden, and ensure the service life of the implant restoration.
[0037] When in use, install the base 2 and the implant 1, and then turn the screw 3. The screw 3 penetrates into the implant 1 along the center point of the base 2 and is connected to the implant 1 through a thread. During this process, the supporting structure supports and limits the ring 6. At the same time, when the base 2 descends, it drives the trapezoidal plate 83 to descend, and when the trapezoidal plate 83 descends, it simultaneously drives the vertical plate 86 to descend. When the vertical plate 86 descends to a predetermined position, the metal strip 88 and the knocking piece 89 are reset by tension because they cannot be blocked by the vertical plate 86. After being reset, the knocking piece 89 knocks on the vertical plate 86, causing the vertical plate 86 to produce a sound.
[0038] Specifically, an abutment 2 is provided inside the implant 1, a screw 3 is connected between the implant 1 and the abutment 2, and the screw 3 is connected to the inside of the implant 1 by a thread, and the implant 1 and the abutment 2 are mechanically squeezed and fixed by the screw 3, and a support structure is fixedly installed on the inner wall of the implant 1, and a circular ring 6 is clamped and installed on the top of the support structure, and a base plate 81 is fixedly connected to the top of the circular ring 6 at an equal distance, and a trapezoidal plate 83 is connected above the base plate 81, and vertical plates 86 that pass through the circular ring 6 and the base plate 81 are symmetrically welded on both sides of the bottom end of the trapezoidal plate 83, and metal strips 88 are symmetrically welded on both sides of the bottom end of the base plate 81, and a knocking piece 89 is fixedly installed on the bottom end of the metal strip 88, and the metal strip 88 and the knocking piece 89 are elastic metal objects, specifically spring steel, and a rectangular hole 87 is provided at the bottom end of the vertical plate 86, and the top and bottom ends of the rectangular hole 87 are close to the end face of the knocking piece 89 with rounded corners, and the bottom end of the knocking piece 89 is set to be V-shaped, and the V-shaped area at the bottom end of the knocking piece 89 is located in the rectangular hole When the vertical plate 86 moves downward, the solid area below the vertical plate 86 moves and contacts the knocking piece 89, causing the knocking piece 89 and the metal strip 88 to deform and bend. When the knocking piece 89 and the metal strip 88 enter the internal position of the rectangular hole 87 of the vertical plate 86, the restoring force of the knocking piece 89 and the metal strip 88 drives them to move, causing them to enter the rectangular hole 87 of the vertical plate 86 and deflect along the rectangular hole 87 to the vertical plate 86, knocking the vertical plate 86, causing the vertical plate 86 to make a sound. A positioning groove 21 is provided at the bottom end of the base 2, and the trapezoidal plate 83 is located inside the positioning groove 21 at the bottom end of the base 2 and fits therewith. At this time, the cooperation of the positioning groove 21 facilitates the connection between the trapezoidal plate 83 and the base 2, and after the connection, the base 2 is fixed to the trapezoidal plate 83 through the cooperation of the positioning groove 21, preventing the base 2 from rotating due to the rotation of the screw 3.
[0039] like Figures 2 to 4 As shown, since the support structure is used to support the circular ring 6, and the position of the circular ring 6 needs to be limited after supporting it to prevent the circular ring 6 from rotating and displacing after installation, the support structure includes: a support ring 4 and a plug-in column 5; the outer side of the support ring 4 is connected to the inner side of the implant 1, and the plug-in column 5 is connected to the top of the support ring 4. The support ring 4 is used to support the plug-in column 5 and limit the circular ring 6 under the action of the plug-in column 5. A positioning hole 72 is provided at the bottom end of the circular ring 6, and the plug-in column 5 is located inside the positioning hole 72 below the circular ring 6. The circular ring 6 and the support ring 4 are connected through the positioning hole 72 and the plug-in column 5.
[0040] When in use, align the positioning hole 72 below the circular ring 6 with the plug-in column 5 at the top of the support ring 4, then place the circular ring 6 on the top of the support ring 4, and then use the extrusion of the base 2 to make the circular ring 6 squeeze the support ring 4, so that the upper and lower positions of the circular ring 6 and the support ring 4 are limited, and through the cooperation of the positioning hole 72 and the plug-in column 5, the circular ring 6 and the support ring 4 are positioned left and right, thereby realizing the upper, lower, left and right positioning of the circular ring 6, thereby preventing the circular ring 6 from being displaced.
[0041] Specifically, a support ring 4 is fixedly connected to the inner wall of the implant 1, a plug-in column 5 is fixedly connected to the top of the support ring 4, and a positioning hole 72 is opened at the bottom of the ring 6 corresponding to the top of the plug-in column 5. The number of positioning holes 72 corresponds to that of the plug-in column 5 and both are set to two.
[0042] like Figure 4 、 Figure 6 and Figure 7 As shown, during the above operation, the trapezoidal plate 83 needs to move vertically (along the Y-axis). At this time, support force is required after the vertical movement (along the Y-axis) to prevent the trapezoidal plate 83 from falling directly on the top of the base plate 81. For this purpose, a plurality of groups of arc-shaped pieces 82 are provided between the top of the base plate 81 and the bottom of the trapezoidal plate 83. The bending direction of the arc-shaped piece 82 is toward the center vertical line of the implant 1 (the midpoint of the screw 3). A bending piece 84 is provided on one side of the innermost arc-shaped piece 82 between the top of the base plate 81 and the bottom of the trapezoidal plate 83 (close to the outer position of the screw 3). The bending direction of the bending piece 84 is toward the center vertical line of the implant 1 (the midpoint of the screw 3), and a ball 85 is provided inside the bending piece 84.
[0043] During use, as the trapezoidal plate 83 moves downward, the trapezoidal plate 83 squeezes the arc piece 82 and the bending part 84 when moving downward, causing the bending part 84 and the arc piece 82 to bend. As the bending part 84 drives the ball 85 to move, the ball 85 enters the outside of the smooth area outside the screw 3, and as the screw 3 continues to descend, the ball 85 rotates inside the bending part 84, and the ball 85 is driven by multiple bending parts 84 to squeeze the screw 3, so that the screw 3 maintains the center vertically when descending, preventing the screw 3 from offsetting after descending, thereby keeping the distance between the circumferential outer side of the screw 3 and the circumferential inner side of the base 2 consistent, preventing deviation problems.
[0044] Specifically, multiple groups of arc-shaped pieces 82 are fixedly connected between the top of the base plate 81 and the bottom of the trapezoidal plate 83, and the bending direction of the arc-shaped piece 82 is toward the center vertical line of the implant 1 (the midpoint of the screw 3). A bending piece 84 is fixedly connected to one side of the innermost arc-shaped piece 82 between the top of the base plate 81 and the bottom of the trapezoidal plate 83 (close to the outer position of the screw 3), and the bending direction of the bending piece 84 is toward the center vertical line of the implant 1 (the midpoint of the screw 3). A ball 85 is movably connected inside the bending piece 84. The arc-shaped piece 82 and the bending piece 84 are both made of medical-grade elastic metal material, specifically cobalt-chromium alloy.
[0045] like Figure 7 and Figure 8 As shown, when the vertical plate 86 descends, the knocking piece 89 and the metal strip 88 enter the internal position of the rectangular hole 87 of the vertical plate 86, and when the vertical plate 86 rises, the knocking piece 89 is located inside the rectangular hole 87, causing the vertical plate 86 to abut against the knocking piece 89 when it rises, causing the knocking piece 89 to bend (bend outward) and unable to enter one end face of the vertical plate 86 (the opposite face of the two vertical plates 86), thereby causing the vertical plate 86 to be unable to be disassembled from the circular ring 6. For this reason, a blocking piece 810 is symmetrically provided on one end face of the vertical plate 86, and the nearest end face of the blocking piece 810 and the metal strip 88 is in contact with the nearest position between the opposite faces of the metal strip 88 and the vertical plate 86. A pushing piece 811 is provided at a position on one end face of the vertical plate 86 between the opposite faces of the two blocking pieces 810, and the pushing piece 811 and the nearest end face of the metal strip 88 are located below the nearest position between the opposite faces of the metal strip 88 and the vertical plate 86.
[0046] When in use, the vertical plate 86 drives the pushing member 811 to rise when it rises, so that the pushing member 811 contacts the metal strip 88 at the nearest point, and the pushing force during the abutment process squeezes the metal strip 88. Since the metal strip 88 is in the shape of an arc, the metal strip 88 moves toward between the two vertical plates 86 at this time. At the same time, under the action of the blocking member 810, it is prevented from moving toward the opposite surfaces of the two vertical plates 86 (the metal strip 88 bends outward). Since the metal strip 88 bends, it drives the knocking member 89 to deflect, so that the knocking member 89 is separated from the rectangular hole 87 of the vertical plate 86, and then continues to move. At this time, when the pushing member 811 is separated from the metal strip 88 at the nearest point, the tension of the metal strip 88 is reset, thereby driving the knocking member 89 to reset. The knocking member 89 is blocked by the solid area of the vertical plate 86, causing the knocking member 89 and the metal strip 88 to bend, so that the bent knocking member 89 moves up and down on the solid area of the vertical plate 86.
[0047] Specifically, a barrier 810 is symmetrically welded to one end of the vertical plate 86. The metal strip 88 is in an arc shape. The nearest point of the arc-shaped metal strip 88 is close to the opposite surfaces of the two vertical plates 86. The nearest end surface of the barrier 810 and the metal strip 88 is in contact with the nearest position between the opposite surfaces of the metal strip 88 and the vertical plate 86. A pusher 811 is welded to one end of the vertical plate 86 between the opposite surfaces of the two barrier 810. The pusher 811 is in contact with the nearest point of the metal strip 88. The end face is located below the nearest position between the metal strip 88 and the opposite surfaces of the vertical plate 86. A plurality of placement grooves 71 are provided inside the circular ring 6. The plurality of placement grooves 71 are arranged at equal distances from the midpoint of the circular ring 6. The vertical plate 86, the blocking member 810 and the pushing member 811 are all vertically movable (along the Y-axis) and connected to the inside of the placement groove 71 of the circular ring 6. The outer side of the pushing member 811 and the two end faces of the rectangular hole 87 are both set to rounded corners, so as to facilitate the connection with the blocking member 810 and the knocking member 89 respectively.
[0048] Working principle: Prepare the implant 1 that has been implanted into the alveolar bone. Then align the plug-in column 5 at the top of the support ring 4 (which has been fixed to the inner wall of the implant 1) with the positioning hole 72 at the bottom of the circular ring 6. Then, place the circular ring 6 stably on the support ring 4. Rotation and upper and lower limit are achieved through the positioning hole 72 and the plug-in column 5. At this time, the circular ring 6 is preliminarily positioned. Then, align the bottom positioning groove 21 of the abutment 2 with the trapezoidal plate 83 to ensure that the trapezoidal plate 83 can be smoothly inserted into the positioning groove 21.
[0049] Then, the abutment 2 is placed inside the implant 1, and the positioning groove 21 at the bottom end is sheathed and fits the trapezoidal plate 83. This prevents the problem of the abutment 2 being rotated by friction when the screw 3 is subsequently turned. As the abutment 2 is lowered, the trapezoidal plate 83 is driven to move downward. When the trapezoidal plate 83 moves downward, the vertical plates 86 welded on both sides of its bottom end move downward synchronously, passing through the bottom plate 81 and the ring 6 along the placement groove 71;
[0050] At this time, the weight or pressure of the base 2 is transmitted through the trapezoidal plate 83, and finally the ring 6 presses the support ring 4 downward, completing the vertical fixation of the ring 6, and together with the plug-in column 5, the ring 6 is completely positioned (up, down, left, and right).
[0051] Then align the screw 3 with the center hole of the abutment 2 and start screwing it in. The screw 3 passes through the center of the abutment 2, and its threaded portion starts to engage with the thread inside the implant 1. At this time, the screw 3 is screwed in and moved downward by the action of the thread. When the screw 3 moves downward, the abutment 2 drives the trapezoidal plate 83 to continue to move downward through the positioning groove 21. When the trapezoidal plate 83 moves downward, it drives the arc piece 82 and the bending part 84 to move toward the outside of the screw 3. At this time, the bending part 84 drives the ball 85 to fit and squeeze the outside of the screw 3. Since multiple bending parts 84 and balls 85 evenly surround the screw 3, centripetal force is provided to ensure that the screw 3 remains vertical during the descent, prevents deviation, and ensures a uniform gap with the inner wall of the abutment 2.
[0052] When the trapezoidal plate 83 moves downward, the vertical plate 86 is simultaneously driven to move downward continuously. In the initial stage of the vertical plate 86 moving downward, its core area (the plate body below the rectangular hole 87) presses against the V-shaped end of the knocking piece 89, and the knocking piece 89 and the metal strip 88 connected thereto are elastically bent and deformed (deflected inwardly), storing energy. When the screw 3 is screwed in to a predetermined depth (i.e., the extrusion force between the abutment 2 and the implant 1 reaches a preset ideal value), the vertical plate 86 also drops to a position where its rectangular hole 87 is aligned with the V-shaped end of the knocking piece 89. At this time, the restoring force generated by the deformation of the metal strip 88 and the knocking piece 89 is instantly released, and the knocking piece 89 rebounds at a high speed (deflected outward), and its V-shaped end strikes the inside of the rectangular hole 87 and contacts the vertical plate 86, producing a sound. After hearing the clear warning sound, the doctor immediately stops tightening the screw 3. At this time, the preset safe and effective connection extrusion force (torque) between the abutment 2 and the implant 1 has been reached.
[0053] When disassembly is required (such as replacement or adjustment), the screw 3 is unscrewed in the opposite direction. The base 2 and the trapezoidal plate 83 and the vertical plate 86 connected thereto will rise due to the restoring force of the arc-shaped piece 82 and the bending piece 84. When the vertical plate 86 rises, the pushing piece 811 on its side (located between the two blocking pieces 810) will first contact the arc-shaped metal strip 88. The upward movement of the pushing piece 811 squeezes the metal strip 88. Due to the arc-shaped design of the metal strip 88 and the restriction of the blocking piece 810, the metal strip 88 is forced to bend toward the gap between the two vertical plates 86 (towards the gap). The vertical plate 86 is moved upwards to the position of the striking piece 89, and the vertical plate 86 is moved upwards to the position of the striking piece 89. The vertical plate 86 is moved upwards to the position of the striking piece 89, and the striking piece 89 is moved downwards to the position of the striking piece 89. The vertical plate 86 is moved upwards to the position of the striking piece 89, and the striking piece 89 is moved upwards to the position of the striking piece 89. The vertical plate 86 is moved upwards to the position of the striking piece 89, and the vertical plate 86 ...
[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
