DETAILED DESCRIPTION

[0037] like Figure 1-9 As shown, a modular implant includes an upper implant 1, a lower implant 3 is arranged below the upper implant 1, a crown 2 is arranged on the upper implant 1, a fixing frame 4 is arranged inside the upper implant 1, the bottom of the fixing frame 4 is connected with a connecting bolt 5 by bolts, the outside of the connecting bolt 5 is connected to the inner wall of the upper implant 1 and the lower implant 3 by a threaded portion, a drug sustained-release module 6 is arranged in the upper implant 1, a fixing module 7 is arranged in the lower implant 3, the fixing module 7 is located below the drug sustained-release module 6, and a sealing module 8 is arranged on the lower implant 3, and the sealing module 8 is located between the drug sustained-release module 6 and the fixing module 7.

[0038] The design is such that after the lower implant 3 is implanted into the patient's alveolar bone, the upper implant 1 is inserted into the lower implant 3 and the fixing module 7 is used to fix the upper implant 1. During the process of inserting the upper implant 1 into the lower implant 3, the sealing module 8 is used to ensure the sealing of the joint between the upper implant 1 and the lower implant 3. The fixing frame 4 connected with the connecting bolts 5 is screwed into the lower implant 3, the crown 2 is installed on the fixing frame 4, and the denture is fixed on the crown 2.

[0039] During the process of patients adapting to dentures, the drug sustained-release module 6 is used to alleviate the patient's discomfort; the drug sustained-release module 6 can be used to alleviate the pain and foreign body sensation caused by the patient's denture implantation surgery, reduce the patient's discomfort after the new denture is implanted, and reduce the frequency of the patient licking and touching the denture during the process of the patient adapting to the implant, thereby reducing the patient's disturbance of the implant and ensuring the implantation effect of the implant.

[0040] The drug sustained-release module 6 includes a sliding groove 601, which is opened on the inner wall of the upper implant 1. A movable ring 602 is slidably connected in the sliding groove 601, and the movable ring 602 is sleeved on the outside of the fixed frame 4. The bottom of the movable ring 602 is fixedly connected to a grinding disc 608 by bolts. A receiving box 609 is arranged on the outside of the connecting bolt 5. The bottom of the receiving box 609 is slidably connected to the inner bottom wall of the upper implant 1 through a guide component. A desensitizing tablet 610 is arranged on the upper side of the receiving box 609. The desensitizing tablet 610 is located below the grinding disc 608. The outside of the desensitizing tablet 610 is clamped with a plurality of circumferentially equidistant buckles 614, and the buckle 614 is fixedly connected to the upper end surface of the receiving box 609 by bolts. A plurality of circumferentially equidistant release holes 603 are opened on the outside of the upper implant 1.

[0041] The bottom of the accommodating box (609) is fitted with the inner bottom wall of the upper implant (1); the guide assembly comprises a plurality of insertion holes (612) formed on the upper end of the accommodating box (609) and close to the outer circumferential surface thereof; each of the insertion holes (612) is slidably connected with a fixing pin (613); the lower end of the fixing pin (613) is fixedly connected to the inner bottom wall of the upper implant (1).

[0042] The upper side of the containing box 609 is provided with a plurality of infiltration holes 615 which are equidistantly distributed around the circumference. The upper side of the containing box 609 is provided with a plurality of openings which are equidistantly distributed around the circumference. The inner walls of the openings are rotatably connected to a cover plate 616 via a bearing.

[0043] In this embodiment, the containing box 609 contains powdered resin.

[0044] like Figure 3 , Figure 4 and Figure 5 As shown, the interior of the fixed frame 4 is slidably connected with a placement tube 604, and a first spring 605 is fixedly connected between the placement tube 604 and the inner bottom wall of the fixed frame 4 by bolts. Two symmetrical vertical grooves 606 are provided on the outside of the fixed frame 4, and sliding shafts 611 are slidably connected in the vertical grooves 606.

[0045] The two sliding shafts 611 are fixedly connected to the outer surface of the placement tube 604 by bolts. Two circumferentially equidistantly distributed inclined grooves 607 are provided on the outside of the movable ring 602, and the inner walls of the two inclined grooves 607 are respectively slidably connected to the outside of the two sliding shafts 611, and the inner wall of the placement tube 604 is connected to the outside of the crown 2 by a threaded portion.

[0046] With this design, after the denture is fixed to the crown 2, during the process of the patient's upper and lower jaws biting together, the denture will be subjected to downward pressure as the biting action occurs. The downward pressure causes the crown 2 to drive the seating cylinder 604 to descend in the fixed frame 4, overcoming the thrust of the first spring 605, so that the sliding shaft 611 on the seating cylinder 604 moves in the bevel groove 607 and drives the movable ring 602 and the grinding disc 608 to descend and rotate along the bevel of the bevel groove 607; the descending and rotating grinding disc 608 contacts the desensitizing tablet 610 and grinds the surface of the desensitizing tablet 610.

[0047] The ground medicine powder is mixed with the saliva or blood infiltrated into the release hole 603, and is discharged from the release hole 603 to the outside of the upper implant 1 when the grinding disc 608 descends next time, so that the medicine reduces the sensitivity of the patient's surgical site.

[0048] After the hyposensitizing tablets 610 are completely consumed, saliva penetrates into the infiltration hole 615 on the upper side of the container box 609, causing the powdered resin inside the container box 609 to expand rapidly, squeezing the cover plate 616 open and rapidly diffusing into the space inside the upper implant 1 and diffusing into the gap at the patient's implant site through the release hole 603, filling the gap and then solidifying.

[0049] In specific application scenarios, the drug sustained-release module 6 is mainly suitable for the drug sustained-release link in the drug sustained-release process, that is, the drug sustained-release module 6 uses the grinding disc 608 and the desensitizing tablets 610 to enable the modular implant to slowly release the drug to the patient's surgical site during the patient's adaptation to the implant, so that the implant site is in a continuous drug-receiving state, helping the patient to recover and improving the patient's postoperative perception.

[0050] like Figure 6 and Figure 7 As shown, the fixing module 7 includes a containing frame 701, which is located outside the connecting bolt 5, and the outside of the containing frame 701 is connected to the inner wall of the lower implant 3 by bolts. The bottom inner wall of the containing frame 701 is connected to a connecting seat 702 by bolts, and the upper side of the connecting seat 702 is rotatably connected to a rotating frame 709 through a bearing, and the upper side of the connecting seat 702 is provided with a plurality of circumferentially equidistantly distributed arc grooves 707, and short shafts 708 are slidably connected in the arc grooves 707.

[0051] The rotating frame (709) is provided with a plurality of strip grooves (710) equidistantly distributed around the circumference on the upper side of the short shafts (708), and fasteners 711 are slidably connected in the strip grooves 710. The plurality of fasteners 711 are connected to the sides opposite to the plurality of short shafts 708 by bolts.

[0052] An isolation ring 9 is arranged outside the connecting bolt 5, the outside of the isolation ring 9 is slidably connected to the inner wall of the rotating frame (709), and the bottom of the isolation ring 9 is fixedly connected to the upper side of the connecting seat 702 by bolts.

[0053] The outside of the isolation ring 9 is slidably connected to a supporting ring 705, and the side of the supporting ring 705 opposite to the rotating frame 709 is fixedly connected to a second spring 706 by bolts, and the bottom of the upper implant 1 is in contact with the upper side of the supporting ring 705.

[0054] An annular groove 703 is provided on the outside of the upper implant 1, and the annular groove 703 is clamped with a fastener 711. A plurality of circular holes 704 equidistantly distributed around the circumference are provided on the bottom inner wall of the annular groove 703. Limiting shafts 712 are slidably connected in the circular holes 704, and the plurality of limiting shafts 712 are fixedly connected to the upper end surface of the rotating frame 709 by bolts.

[0055] With such a design, after the lower implant 3 is implanted into the patient's alveolar bone, the upper implant 1 is inserted into the lower implant 3 along the isolation ring 9, and the upper implant 1 is pressed downward so that the upper implant 1 presses the supporting ring 705 and pushes the supporting ring 705 to overcome the thrust of the second spring 706 and descend, and the circular hole 704 is aligned with the limiting shaft 712 on the rotating frame 709 and inserted.

[0056] After the upper implant 1 drops to the limit position, the upper implant 1 is rotated so that the limiting shaft 712 connected to the upper implant 1 drives the rotating frame 709 to rotate, so that the arc groove 707 on the connecting seat 702 pushes the short shaft 708 connected to the fastener 711 to move in the direction of the isolation ring 9, and finally the fastener 711 clamps the annular groove 703 and releases the upper implant 1. At this time, the upper implant 1 is fixed on the lower implant 3.

[0057] In specific application scenarios, the fixing module 7 is mainly suitable for the fixing link in the fixing process, that is, the fixing module 7 uses the arc groove 707 and the fastener 711 to enable the device to achieve a fixing effect through simple rotation. At the same time, the fastener 711 is used to lock the circular hole 704, thereby preventing the upper implant 1 from falling off the lower implant 3 due to vibration or impact after being fixed on the lower implant 3, thereby improving stability.

[0058] like Figure 8 and Fig. 9As shown, the sealing module 8 includes a fitting ring 801, which is located in the lower implant 3, the bottom of the fitting ring 801 is fixedly connected to the bottom inner wall of the containing frame 701 by bolts, the outside of the fitting ring 801 is fitted with the inner wall of the containing frame 701, the inner wall of the fitting ring 801 is slidably connected to the outside of the upper implant 1, the upper side of the fitting ring 801 is fixedly connected with an annular rubber strip 803, and an annular groove is opened on the outside of the upper implant 1, a rubber ring 804 is fixedly connected in the annular groove, and the outside of the rubber ring 804 is fitted with the outside of the annular rubber strip 803.

[0059] An annular groove 802 is provided on the upper side of the accommodating frame 701, and a plurality of rectangular grooves 806 equidistantly distributed around the circumference are provided on the inner wall of the annular groove 802. Two symmetrical sliders 807 are slidably connected in the rectangular grooves 806, and the opposite sides of the two sliders 807 located on the same rectangular groove 806 are fixedly connected with the same third spring 809 by bolts.

[0060] The two sliders 807 located on the same rectangular groove 806 are rotatably connected to the connecting rod 808 on one side close to the annular rubber strip 803 through a bearing, and the two connecting rods 808 are rotatably connected to the same push plate 805 on one end away from the sliders 807, and the sides of the multiple push plates 805 close to the annular rubber strip 803 are in contact with the outside of the annular rubber strip 803.

[0061] With such a design, during the process of inserting the upper implant 1 into the lower implant 3, the rubber ring 804 fixed on the outside of the upper implant 1 contacts the annular rubber strip 803 during the process of the upper implant 1 being inserted, and squeezes and deforms the upper half of the annular rubber strip 803, so that the deformed annular rubber strip 803 pushes the push plate 805, so that the two connecting rods 808 connected to the push plate 805 push the two sliders 807 to move oppositely along the rectangular groove 806, so that the rubber ring 804 can continue to descend smoothly. After the upper implant 1 is fixed on the lower implant 3, the rubber ring 804 is squeezed on the middle part of the annular rubber strip 803 and is in close contact with the annular rubber strip 803. At this time, the upper part of the annular rubber strip 803 loses its thrust, and under the pull of the third spring 809, the push plate 805 quickly pushes the upper part of the annular rubber strip 803 back to its original position, thereby sealing the contact edge between the annular rubber strip 803 and the upper implant 1.

[0062] In a specific application scenario, the sealing module 8 is mainly suitable for the sealing link in the sealing process, that is, the sealing module 8 uses the annular rubber strip 803 and the rubber ring 804 to enable the device to reduce bacterial microleakage at the gap interface after implantation, thereby reducing the chance of peri-implantitis in patients after implant surgery.

[0063] The present invention also provides a method for using a modular implant, based on the above modular implant, comprising the following steps:

[0064] Step 1: After the lower implant 3 is implanted into the patient's alveolar bone, the upper implant 1 is inserted into the lower implant 3 and the fixing module 7 is used to fix the upper implant 1 .

[0065] The specific operation process of step one is as follows: after the lower implant 3 is implanted into the patient's alveolar bone, the upper implant 1 is inserted into the lower implant 3 along the isolation ring 9, the upper implant 1 is pressed downward so that the upper implant 1 presses the supporting ring 705 and pushes the supporting ring 705 to overcome the thrust of the second spring 706 and descend, the circular hole 704 is aligned with the limiting shaft 712 on the rotating frame 709 and inserted, after the upper implant 1 descends to the limit position, the upper implant 1 is rotated so that the limiting shaft 712 connected to the upper implant 1 drives the rotating frame 709 to rotate, so that the arc groove 707 on the connecting seat 702 pushes the short shaft 708 connected to the fastener 711 to move in the direction of the isolation ring 9, and finally the fastener 711 clamps the annular groove 703 and releases the upper implant 1. At this time, the upper implant 1 is fixed on the lower implant 3.

[0066] Step 2: During the process of inserting the upper implant 1 into the lower implant 3 , a sealing module 8 is used to ensure the sealing of the joint between the upper implant 1 and the lower implant 3 .

[0067] The specific operation process of step 2 is as follows: during the process of inserting the upper implant 1 into the lower implant 3, the rubber ring 804 fixed on the outside of the upper implant 1 contacts the annular rubber strip 803 during the process of the upper implant 1 being inserted and squeezes and deforms the upper half of the annular rubber strip 803, so that the deformed annular rubber strip 803 pushes the push plate 805, so that the two connecting rods 808 connected to the push plate 805 push the two sliders 807 to move in opposite directions along the rectangular groove 806, so that the rubber ring 804 can continue to descend smoothly. After the upper implant 1 is fixed on the lower implant 3, the rubber ring 804 is squeezed on the middle part of the annular rubber strip 803 and is in close contact with the annular rubber strip 803. At this time, the upper part of the annular rubber strip 803 loses its thrust. Under the pull of the third spring 809, the push plate 805 quickly pushes the upper part of the annular rubber strip 803 back to its original position, and the contact edge of the annular rubber strip 803 and the upper implant 1 is sealed.

[0068] Step three, screw the fixing frame 4 connected with the connecting bolts 5 into the lower implant 3, install the crown 2 on the fixing frame 4, fix the denture on the crown 2, and use the drug sustained-release module 6 to alleviate the patient's discomfort during the process of the patient adapting to the denture.

[0069] The specific operation process of step three is as follows: after the denture is fixed to the crown 2, during the process of the patient's upper and lower jaws biting together, the denture will be subjected to downward pressure as the biting action progresses, and the downward pressure causes the crown 2 to drive the placement tube 604 to descend in the fixed frame 4, overcoming the thrust of the first spring 605, so that the sliding shaft 611 on the placement tube 604 moves in the inclined groove 607 and drives the grinding disc 608 connected to the movable ring 602 to descend and rotate along the inclined surface of the inclined groove 607, and the descending and rotating grinding disc 608 contacts the desensitizing tablet 610 and desensitizes the desensitizing tablet 610. The surface is polished, and the polished medicine powder is mixed with the saliva or blood infiltrated into the release hole 603, and is discharged from the release hole 603 to the outside of the upper implant 1 when the polishing disc 608 descends next time, so that the medicine reduces the sensitivity of the patient's surgical site. After the desensitizing tablets 610 are completely consumed, the infiltration holes 615 on the upper side of the receiving box 609 penetrate into the saliva, causing the powdered resin inside the receiving box 609 to expand rapidly, squeezing the cover plate 616 open and quickly diffusing into the space inside the upper implant 1 and diffusing into the gap of the patient's implant site through the release hole 603, filling the gap and solidifying.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
