Description

Technical Field

[0001] The invention relates to the field of dental implants, and in particular to an implant system, a denture fixing method, and a pre-tightening tool. Background Art

[0002] Dental implants are recognized by the dental community as the best way to repair missing teeth. Currently, there are two common methods for fixing dentures to implant bases, namely adhesive retention and screw retention, and both methods have certain problems.

[0003] The bonding material of the adhesive retention method will dissolve over time, resulting in micro-leakage. At the same time, the bonding residue is harmful and difficult to remove, and can easily cause inflammation of the surrounding tissues. When the connecting screws in the abutment become loose, the denture and the abutment need to be destroyed, which makes maintenance more difficult and more costly.

[0004] The screw-retained method has the advantages of predictability and retrievability. The denture is easier to remove when hygiene maintenance, restoration or surgical intervention is required. If the connection screw loosens, the abutment can be tightened directly through the screw access hole. Therefore, the screw-retained method has certain advantages over the adhesive retention method.

[0005] However, the screw retention method requires a screw entry hole to be reserved on the denture, which makes the denture lack a complete occlusal surface. The screw entry hole affects the aesthetics and is also prone to accumulate food debris. Summary of the invention

In the pores; moreover, the built-in magnet is driven by the magnetic field to drive the output block to rotate rapidly, and the rapidly rotating stop column is used to impact the stop block of the locking piece, so that the screw of the locking piece is tightened in the threaded hole through the impact force, and the screw is pre-tightened, so that the denture is fastened down to the top of the base, and the installation of the denture is completed; the implant system of the present invention completes the fixation of the denture through the screw retention method, and there is no need to use adhesive materials to bond the denture to the base, and there is no need to open a screw entry hole on the denture, so that the denture forms a complete occlusal surface, making the denture restoration more beautiful.

[0047] Reference Figures 1 to 3 The planting system of the present invention is implemented as follows:

[0048] The implant system includes an abutment 110 , a denture 130 , a built-in magnet 200 , an output block 300 , and a locking member 500 .

[0049] An assembly hole 111 penetrating in the up-down direction is disposed on the top of the base 110 , and the built-in magnet 200 , the output block 300 , and the locking member 500 are all disposed in the assembly hole 111 .

[0050] The built-in magnet 200 is cylindrical, and the outer diameter of the built-in magnet 200 is smaller than the inner diameter of the assembly hole 111 . The built-in magnet 200 rotates around the axis of the assembly hole 111 , and two magnetic poles of the built-in magnet 200 are arranged side by side in the horizontal direction.

[0051] The output block 300 is mounted on the top of the built-in magnet 200, and the output block 300 rotates synchronously with the built-in magnet 200. A stopper 310 is arranged on the top of the output block 300, and the stopper 310 is staggered from the rotation axis of the output block 300.

[0052] The locking member 500 is rotatably disposed in the assembly hole 111 of the base 110 , and a stopper 510 is disposed at the bottom of the locking member 500 . The stopper 510 is disposed on the rotation track of the stopper column 310 , that is, the stopper column 310 contacts the stopper 510 after the output block 300 rotates.

[0053] A screw rod 520 is disposed on the top of the locking member 500 , and the screw rod 520 passes through the assembly hole 111 of the base 110 and extends upward.

[0054] The bottom of the denture 130 is mounted on the top of the base 110 . A threaded hole 610 is provided at the bottom of the denture 130 . The thread of the threaded hole 610 matches the thread of the screw rod 520 .

[0055] The screw 520 of the locking member 500 is used to be screwed into the threaded hole 610 so that the artificial tooth 130 is fixed on the top of the base 110 .

[0056] The implant system also includes an implant 100 and a central screw 120. A mating hole is set at the top of the implant 100, and a screw hole extending downward is set at the bottom of the mating hole. The mating hole is used to install the bottom of the base 110. The central screw 120 passes through the assembly hole 111 of the base 110 and is screwed into the screw hole of the implant 100, so that the base 110 is fixed to the mating hole of the implant 100, and the denture 130 is used to be mounted on the top of the base 110.

[0057] After the implant 100 of the implant system is implanted into the patient's jawbone, the base 110 is mounted on the implant 100 using the central screw 120, and the built-in magnet 200, the output block 300, the locking piece 500 and other components are installed into the assembly hole 111 of the base 110, and the screw 520 of the locking piece 500 passes through the assembly hole 111 of the base 110 and extends upward.

[0058] When installing the denture 130, the denture 130 is mounted on the top of the base 110, and the screw 520 of the locking piece 500 is aligned with the threaded hole 610 of the denture 130. Then, the magnetic field is used to attract the built-in magnet 200 to rotate around the vertical axis, so that the built-in magnet 200 drives the output block 300 to rotate, and the stop column 310 of the output block 300 pushes the stop block 510 of the locking piece 500, thereby screwing the screw 520 of the locking piece 500 into the threaded hole 610.

[0059] Moreover, the magnetic field is utilized to make the built-in magnet 200 drive the output block 300 to rotate rapidly, and the rapidly rotating blocking column 310 is utilized to impact the blocking block 510 of the locking member 500, so that the screw 520 of the locking member 500 is tightened into the threaded hole 610 through the impact force, thereby completing the pre-tightening of the screw 520, and the denture 130 is fastened down to the top of the base 110, thereby completing the installation of the denture 130.

[0060] The implant system of the present invention fixes the denture 130 through a screw retention method. There is no need to use adhesive materials to bond the denture 130 to the base 110, and there is no need to open screw entry holes on the denture 130, so that the denture 130 forms a complete occlusal surface, which makes it easier to control the occlusion and make the denture 130 restoration more beautiful.

[0061] In some embodiments, a mounting hole 131 is provided at the bottom of the denture 130, and the shape of the mounting hole 131 matches the top of the base 110. The implant system is also provided with a fixing seat 600, which is installed in the mounting hole 131, and a threaded hole 610 is provided at the bottom of the fixing seat 600.

[0062] The bottom of the denture 130 retains the original mounting hole 131 to ensure the structural strength of the denture 130. In addition, a fixing seat 600 is installed in the mounting hole 131 of the denture 130 and a threaded hole 610 is opened on the fixing seat 600, which helps to reduce damage to the structure of the denture 130 and improve the pressure-bearing capacity of the denture 130 during chewing.

[0063] In some embodiments, a rotation-stopping structure is disposed between the inner wall of the mounting hole 131 and the outer wall of the base 110 .

[0064] When the screw 520 of the locking member 500 is screwed into the threaded hole 610 of the fixing seat 600 , the anti-rotation structure prevents the denture 130 from rotating relative to the base 110 , thereby ensuring that the screw 520 is pre-tightened so that the denture 130 is more firmly installed on the top of the base 110 .

[0065] In some embodiments, the implantation system is further provided with a sealing ring 800 , which is disposed between the inner wall of the mounting hole 131 and the outer wall of the base 110 .

[0066] The sealing ring 800 is used to seal the gap between the denture 130 and the base 110 to improve the sealing effect and prevent leakage of the implant system. The compressed sealing ring 800 will also generate elastic force on the mounting hole 131 of the denture 130, so that the denture 130 is more firmly installed on the top of the base 110.

[0067] In some embodiments, the upper section of the base 110 cooperates with the mounting hole 131 of the denture 130 . The mounting hole 131 is a tapered hole, and the aperture of the mounting hole 131 gradually increases from top to bottom. The shape of the upper section of the base 110 matches the shape of the mounting hole 131 .

[0068] After the screw 520 of the locking member 500 is tightened into the threaded hole 610 of the fixing seat 600, the denture 130 is pulled downward by the screw 520 so that the mounting hole 131 is pressed against the upper outer wall of the base 110, forming a seal between the upper section of the base 110 and the mounting hole 131 to prevent leakage of the implant system.

[0069] In some embodiments, a limiting column 530 is set at the bottom of the locking member 500, and a limiting hole 320 is set at the top of the output block 300. The axis of the limiting hole 320 coincides with the rotation axis of the locking member 500. The limiting column 530 is passed through the limiting hole 320, and the limiting column 530 can rotate in the limiting hole 320.

[0070] By cooperating with the limiting column 530 and the limiting hole 320, the rotation axis of the locking member 500 coincides with the rotation axis of the output block 300, so as to ensure that the output block 300 drives the locking member 500 to rotate more smoothly; moreover, since the outer diameter of the built-in magnet 200 is smaller than the inner diameter of the assembly hole 111, the built-in magnet 200 is easy to shake in the assembly hole 111 and rub the inner wall of the assembly hole 111, and the locking member 500 is limited by the avoiding hole 410 of the fixing member 400, and the locking member 500 is 0 is inserted into the limiting hole 320 of the output block 300 and the output block 300 is connected to the built-in magnet 200. Then, under the constraints of the limiting post 530 and the limiting hole 320, the built-in magnet 200 can only rotate in the assembly hole 111, reducing the shaking amplitude of the built-in magnet 200 in the assembly hole 111, and greatly reducing the friction resistance between the inner wall of the assembly hole 111 and the outer wall of the built-in magnet 200, so that the built-in magnet 200 can rotate more smoothly.

[0071] In some embodiments, a first ball head 531 is disposed at the bottom of the limiting column 530, and the first ball head 531 is semi-spherical. The bottom of the first ball head 531 abuts against the bottom wall of the limiting hole 320 of the output block 300, or the bottom of the first ball head 531 passes through the limiting hole 320 and abuts against the top surface of the built-in magnet 200.

[0072] The limiting column 530 contacts the output block 300 or the built-in magnet 200 through the first ball head 531, reducing the friction resistance of the bottom of the limiting column 530 relative to the output block 300 or the built-in magnet 200, so that the built-in magnet 200 and the output block 300 can rotate more smoothly.

[0073] In some embodiments, the implant system also includes a central screw 120 and a guide column 700. The central screw 120 is passed through the lower half of the assembly hole 111 and extends downward from the bottom of the assembly hole 111. The built-in magnet 200, the output block 300, the fixing part 400, and the locking part 500 are arranged in the upper half of the assembly hole 111. The screw 520 of the locking part 500 extends upward from the top of the assembly hole 111. The guide column 700 is installed at the bottom of the built-in magnet 200. The guide column 700 is located on the rotation axis of the built-in magnet 200. A screw groove 121 is set at the top of the central screw 120, and the guide column 700 is inserted into the screw groove 121.

[0074] The guide post 700 is inserted into the screw groove 121, and the central screw 120 is fixed in the assembly hole 111 of the base 110, that is, the central screw 120 and the base 110 are relatively fixed, and the built-in magnet 200 needs to rotate in the assembly hole 111 of the base 110. Since the outer diameter of the built-in magnet 200 is smaller than the inner diameter of the assembly hole 111, the built-in magnet 200 is easy to shake in the assembly hole 111 and rub the inner wall of the assembly hole 111; the guide post 700 at the bottom of the built-in magnet 200 is used to cooperate with the screw groove 121 of the central screw 120, so that the guide post 700 and the screw groove 121 constrain the built-in magnet 200, reduce the shaking amplitude of the built-in magnet 200 in the assembly hole 111, thereby reducing the friction between the built-in magnet 200 and the inner wall of the assembly hole 111, and making the built-in magnet 200 rotate more smoothly.

[0075] In some embodiments, a second ball head 710 is disposed at the bottom of the guide post 700 . The second ball head 710 is in a semi-spherical shape and abuts against the bottom wall of the screw slot 121 .

[0076] The guide post 700 contacts the bottom wall of the screw slot 121 of the central screw 120 through the second ball head 710 , reducing the friction resistance of the bottom of the guide post 700 relative to the bottom wall of the screw slot 121 , making the rotation of the built-in magnet 200 smoother.

[0077] In some embodiments, the implantation system is further provided with a fixing member 400, which is installed at the top of the assembly hole 111, and the fixing member 400 is provided with an avoidance hole 410 which passes through in the up-down direction.

[0078] The locking member 500 is rotatably disposed in the avoidance hole 410 , and a stopper 510 is disposed at the bottom of the locking member 500 . The stopper 510 is disposed on the rotation track of the stopper column 310 , that is, the stopper column 310 contacts the stopper 510 after the output block 300 rotates.

[0079] A screw rod 520 is disposed on the top of the locking member 500 , and the screw rod 520 passes through the avoidance hole 410 upwards.

[0080] The fixing member 400 is used to limit the locking member 500 to prevent the locking member 500 from being disengaged from the base 110, so that the locking member 500 is more firmly connected to the denture 130 and the base 110.

[0081] Specifically, the implant system of this embodiment includes an implant 100 , a base 110 , a central screw 120 , a denture 130 , a built-in magnet 200 , an output block 300 , a fixing member 400 , a locking member 500 , a fixing seat 600 , a guide column 700 , and a sealing ring 800 .

The outer diameter of the polished rod is smaller than the inner diameter of the thread of the avoiding hole 410, so that after the screw rod 520 passes through the avoiding hole 410 and extends above the fixing piece 400, the polished rod can rotate in the avoiding hole 410, and the stopper 510 and the limiting column 530 are located below the fixing piece 400.

[0092] The stopper 510 extends in the horizontal direction and is disposed on the rotation track of the stopper column 310 .

[0093] The limiting post 530 is downwardly penetrated into the limiting hole 320 of the output block 300 . A first ball head 531 is disposed at the bottom of the limiting post 530 . The first ball head 531 abuts against the top surface of the built-in magnet 200 .

[0094] The gap between the outer wall of the limiting column 530 and the inner wall of the limiting hole 320 is smaller than the gap between the outer wall of the built-in magnet 200 and the inner wall of the assembly hole 111 .

[0095] A mounting hole 131 is arranged at the bottom of the denture 130. The mounting hole 131 is in the shape of a tapered hole which is smaller at the top and larger at the bottom. The upper section of the base 110 is in the shape of a tapered structure which is smaller at the top and larger at the bottom. An anti-rotation key 132 protruding inwardly is arranged on the inner wall of the mounting hole 131. A recessed anti-rotation groove 112 is arranged on the outer side wall of the upper section of the base 110. The mounting hole 131 of the denture 130 is sleeved on the upper section of the base 110. The anti-rotation key 132 cooperates with the anti-rotation groove 112 to form a rotation-stopping structure. The anti-rotation key 132 cooperates with the anti-rotation groove 112 to limit the freedom of rotation of the denture 130 relative to the base 110.

[0096] The fixing seat 600 is fixed to the top of the mounting hole 131. The fixing seat 600 is provided with a threaded hole 610 which passes through in the up-down direction. The screw 520 of the locking member 500 is screwed into the threaded hole 610 of the fixing seat 600 so that the denture 130 is fixed to the top of the base 110. The sealing ring 800 is sleeved on the upper section of the base 110. The sealing ring 800 closes the gap between the outer wall of the base 110 and the inner wall of the mounting hole 131.

[0097] After the implant 100 of the implant system is implanted into the patient's jawbone, the base 110 is installed on the implant 100 using the central screw 120, and the built-in magnet 200, the output block 300, the fixing part 400, the locking part 500 and other components are installed in the assembly hole 111 of the base 110. The screw 520 of the locking part 500 extends upward through the avoidance hole 410 of the fixing part 400, and then the denture 130 is sleeved on the top of the base 110. The built-in magnet 200 drives the output block 300 to rotate through the magnetic field, so that the stop column 310 of the output block 300 drives or hits the stop block 510 of the locking part 500, so that the locking part 500 drives the screw 520 to be screwed into the threaded hole 610 of the fixing seat 600, so that the denture 130 is fixed to the top of the base 110 and the sealing ring 800 is pressed.

[0098] Reference Figures 4 to 5 The denture fixing method of the implant system of the present invention is implemented as follows:

[0099] The implant system denture fixation method includes the following steps:

[0100] Reference Figure 4 As shown, an external magnetic field is applied to the implant system, and the rotation direction of the screw 520 is right-handed. When observing the screw 520 and the threaded hole 610 from bottom to top, the screw 520 can be screwed into the threaded hole 610 by rotating in a clockwise direction. The clockwise rotation is the positive rotation direction, causing the external magnetic field to rotate clockwise.

[0101] The built-in magnet 200 is attracted by the external magnetic field, so that the built-in magnet 200 drives the output block 300 to rotate clockwise, and then the two blocking posts 310 of the output block 300 rotate clockwise and contact the blocking block 510 of the locking member 500. The locking member 500 rotates clockwise to screw the screw 520 into the threaded hole 610 of the denture 130.

[0102] As the screw rod 520 is gradually screwed into the threaded hole 610 , the artificial tooth 130 moves downward. When the thrust of the output block 300 driven by the built-in magnet 200 is not enough to screw the screw rod 520 , the screw rod 520 prevents the output block 300 from rotating.

[0103] The external magnetic field continues to rotate clockwise by 90° to 180°, which can provide a screw-in torque for the screw rod 520 , thereby providing a basic pre-tightening force for the screw rod 520 and generating an anti-screwing torque, thereby making it difficult for the screw rod 520 to be screwed out of the threaded hole 610 .

[0104] Reference Figure 5As shown, the external magnetic field is then weakened, and the external magnetic field rotates counterclockwise at a uniform speed. The built-in magnet 200 is attracted by the external magnetic field, so that the built-in magnet 200 drives the output block 300 to rotate counterclockwise until the blocking column 310 abuts against the block 510 of the locking member 500 in another direction. Due to the anti-rotation torque between the screw 520 and the threaded hole 610, the blocking column 310 is blocked by the block 510.

[0105] The external magnetic field continues to rotate counterclockwise at a uniform speed, so that the direction of the external magnetic field is the same as the direction of the magnetic pole of the built-in magnet 200. At this time, the built-in magnet 200 is at the critical point of reversal. The external magnetic field continues to rotate counterclockwise at a uniform speed, and the built-in magnet 200 is attracted by the external magnetic field. The built-in magnet 200 rotates clockwise so that the N pole of the built-in magnet 200 points to the direction of the external magnetic field. The built-in magnet 200 drives the output block 300 to rotate clockwise at an accelerated speed. The output block 300 drives the blocking column 310 to rotate clockwise at an accelerated speed to hit the blocking block 510 of the locking member 500, so that the screw 520 of the locking member 500 is subjected to the impact force and is screwed into the threaded hole 610, thereby providing the screw 520 with a preload force that is much greater than the basic preload force.

[0106] The magnetic field strength of the external magnetic field is gradually increased, and the previous step is repeated, so as to pre-tighten the screw 520 and the threaded hole 610 , so that the denture 130 is fixed on the top of the base 110 .

[0107] Reference Figure 6 to Figure 7 The pre-tightening tool of the present invention is implemented as follows:

[0108] The pre-tightening tool is used to implement the denture fixation method of the implant system as described above.

[0109] The pre-tightening tool includes a clamp 900 and a driving magnet 910 .

[0110] The bottom of the clamp 900 is provided with two clamping blocks which are horizontally spaced apart, and a clamping space for clamping the denture 130 is formed between the two clamping blocks. The top of the clamp 900 is provided with a rotating shaft 901 which extends upward.

[0111] The driving magnet 910 is cylindrical, and its two magnetic poles are arranged side by side in the horizontal direction. The driving magnet 910 is provided with an axial hole 911 which passes through in the up-down direction. The axial hole 911 is sleeved on the rotating shaft 901 , and the driving magnet 910 rotates around the rotating shaft 901 and slides up and down.

[0112] When in use, the two clamps limit the denture 130 in the clamping space, so that the axis of the rotating shaft 901 coincides with the axis of the assembly hole 111, and the driving magnet 910 rotates around the rotating shaft 901 so that the magnetic field generated by the driving magnet 910 rotates accordingly.

[0113] The driving magnet 910 slides up and down along the rotating shaft 901 , so that the distance between the driving magnet 910 and the built-in magnet 200 changes, thereby changing the magnetic field strength of the driving magnet 910 at the position of the built-in magnet 200 .

[0114] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
