Description

Technical Field

[0001] This application relates to the field of oral implant technology, and in particular to a healing abutment structure for electromagnetic bone integration. Background Technology

[0002] The success of traditional dental implants relies heavily on osseointegration, which means the implant achieves a tight, biological fusion with the alveolar bone. This process requires the implant to remain absolutely stable after placement, and the healing period is lengthy, typically 3 to 6 months. During this time, patients are forced to remain toothless for an extended period, severely impacting their chewing function and daily life.

[0003] Currently, referring to the patent document with publication number CN203468766U, an electromagnetic stimulation dental implant device has an electromagnetic generator installed in the abutment. The electromagnetic generator can generate a low-frequency electromagnetic field when energized, which can effectively promote the proliferation, differentiation and calcium absorption of osteoblasts in the damaged bone tissue around the implant, thereby reducing the time required for osseointegration.

[0004] However, the quality of alveolar bone varies among patients, and the rate of bone integration differs under the influence of low-frequency electromagnetic fields. This can lead to significant differences in the bone integration time among patients, which in turn can interfere with the doctor's prediction of the treatment progress. Utility Model Content

[0005] To make the time required for bone integration more similar for different patients, this application provides an electromagnetic bone integration-promoting healing abutment structure.

[0006] The electromagnetic bone-integrating healing abutment structure provided in this application adopts the following technical solution:

[0007] An electromagnetic bone-healing abutment structure includes an abutment body with a receiving cavity having a top opening. An electromagnetic generating component is disposed within the receiving cavity of the abutment body. When energized, the electromagnetic generating component generates an electromagnetic field that stimulates bone tissue growth and healing. A magnetic field adjusting component connected to the electromagnetic generating component is disposed on the abutment body, and the magnetic field adjusting component is used to adjust the magnitude of the electromagnetic field strength.

[0008] By adopting the above technical solution, the electromagnetic generator component generates a low-frequency electromagnetic field when energized, which effectively promotes the growth and healing of damaged bone tissue around the implant, reduces the time required for bone integration, and when the abutment structure is used for patients with good bone quality, the electromagnetic generator component is adjusted using a magnetic field adjuster to make the intensity of the electromagnetic field generated by the electromagnetic generator component lower. When the abutment structure is used for patients with poor bone quality, the electromagnetic generator component is adjusted using a magnetic field adjuster to make the intensity of the electromagnetic field generated by the electromagnetic generator component higher. This makes the bone integration time of different patients less different, which facilitates the doctor's prediction of the treatment process.

[0009] Preferably, the electromagnetic generating assembly includes an iron core, a coil, a power supply, and a control circuit board. The iron core is fixedly disposed within the base body, the coil is sleeved on the iron core, and the control circuit board and the power supply are both disposed within the base body.

[0010] By adopting the above technical solution, the power supply provides power to the control circuit board, and the control circuit board passes current through the coil to generate an electromagnetic field.

[0011] Preferably, a pressure sensor is provided on the control circuit board, and the magnetic field adjustment component is adjustablely disposed in the base body along the axial direction of the base body. The end of the magnetic field adjustment component abuts against the pressure sensor, and the pressure value of the pressure sensor is proportional to the output current value of the control circuit board.

[0012] By adopting the above technical solution, the magnetic field adjustment component is adjusted along the axial direction of the base body. The slight movement of the magnetic field adjustment component causes a change in the pressure value detected by the pressure sensor. The control circuit board then adjusts the output current accordingly based on the change in pressure value, thereby adjusting the magnitude of the electromagnetic field strength.

[0013] Preferably, the magnetic field adjusting component is threaded into the base body, and a first internal hexagonal groove is formed inside the magnetic field adjusting component.

[0014] By adopting the above technical solution, a hexagonal screwdriver is inserted into the first internal hexagonal slot. The hexagonal screwdriver drives the magnetic field adjustment component to rotate. Under the action of the thread, the magnetic field adjustment component is displaced along the axial direction of the base body, thereby adjusting the electromagnetic field.

[0015] Preferably, slots are provided on both opposite sides of the end wall of the base body.

[0016] By adopting the above technical solution, when adjusting the magnetic field adjustment component by rotation, first use an anti-rotation wrench to engage in the two slots of the base body, then pass the hexagonal screwdriver through the clearance hole of the anti-rotation wrench and insert it into the first internal hexagonal slot, thereby facilitating precise rotation of the magnetic field adjustment component.

[0017] Preferably, the end face of the base body is provided with multiple marking lines at equal intervals along its own axis, and the end face of the magnetic field adjustment component is provided with indicator lines.

[0018] By adopting the above technical solution, when the magnetic field adjustment component is rotated to adjust the electromagnetic field, the magnetic field adjustment component drives the indicator scale to rotate. The marking scale on the base body makes it easy to judge the rotation angle of the magnetic field adjustment component, thereby adjusting the electromagnetic field to different intensities.

[0019] Preferably, the iron core passes through the magnetic field adjusting component and is threadedly fixed to the base body. A second internal hexagonal groove is provided on the end face of the iron core. One end of the iron core is located inside the magnetic field adjusting component. A first retaining ring is provided on the end of the iron core located in the magnetic field adjusting component. A second retaining ring is provided on the end of the inner sidewall of the magnetic field adjusting component.

[0020] By adopting the above technical solution, a hexagonal screwdriver is inserted into the second internal hexagonal slot, and the iron core is rotated and installed in the base body by the hexagonal screwdriver. The first retaining ring on the iron core cooperates with the second retaining ring on the magnetic field adjustment component, so that the magnetic field adjustment component will not fall off the base body.

[0021] Preferably, both the power supply and control circuit board are ring-shaped, and the power supply and control circuit board are sleeved on the iron core.

[0022] By adopting the above technical solution, the iron core limits the ring-shaped power supply and control circuit board, making the power supply and control circuit board more stable when installed in the base body.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By using a magnetic field regulator, the electromagnetic generator produces a low-frequency electromagnetic field when energized, which effectively promotes the growth and healing of damaged bone tissue around the implant, reducing the time required for bone integration. When the abutment structure is used for patients with good bone quality, the magnetic field regulator is used to adjust the electromagnetic generator to produce a lower intensity of the electromagnetic field. When the abutment structure is used for patients with poor bone quality, the magnetic field regulator is used to adjust the electromagnetic generator to produce a higher intensity of the electromagnetic field. This makes the time for bone integration less different among different patients, which is convenient for doctors to predict the treatment progress.

[0025] 2. Using a pressure sensor, the magnetic field adjustment component is adjusted along the axis of the base body. The slight movement of the magnetic field adjustment component causes a change in the pressure value detected by the pressure sensor. The control circuit board then adjusts the output current accordingly based on the change in pressure value, thereby adjusting the magnitude of the electromagnetic field strength.

[0026] 3. When adjusting the magnetic field adjustment component by means of the slots, first use an anti-rotation wrench to engage in the two slots of the base body, then pass the hexagonal screwdriver through the clearance hole of the anti-rotation wrench and insert it into the first internal hexagonal slot, so as to facilitate precise rotation of the magnetic field adjustment component.

[0032] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0033] This application discloses an electromagnetic bone-integrating healing abutment structure.

[0034] Reference Figure 1 , Figure 2 and Figure 3 An electromagnetic bone-bonding healing abutment structure includes an abutment body 1, a receiving cavity 2 is provided inside the abutment body 1, the top of the receiving cavity 2 is provided, and an electromagnetic generating component 3 is installed in the receiving cavity 2 within the abutment body 1.

[0035] The electromagnetic generating assembly 3 includes an iron core 31, a coil 32, a power supply 33, and a control circuit board 34. The coil 32 is placed at the bottom of the cavity 2 of the base body 1. The power supply 33 and the control circuit board 34 are both ring-shaped. The power supply 33 is placed above the coil 32, and the control circuit board 34 is placed above the power supply 33. Both the power supply 33 and the coil 32 are electrically connected to the control circuit board 34.

[0036] The iron core 31 has a second internal hexagonal slot 10 at the top center. The iron core 31 passes through the coil 32, the power supply 33, and the control circuit board 34, and the bottom end of the iron core 31 is threaded and fixed inside the base body 1. By inserting a hexagonal screwdriver into the second internal hexagonal slot 10, the iron core 31 can be rotated, thereby installing the electromagnetic generator assembly 3 inside the base body 1.

[0037] A magnetic field adjusting component 4 is threadedly installed at the opening of the receiving cavity 2 on the base body 1. The magnetic field adjusting component 4 has a first internal hexagonal groove 6. Slots 7 are provided on the opposite side walls of the top of the base body 1. A pressure sensor 5 is fixedly installed on the control circuit board 34. The pressure sensor 5 is electrically connected to the control circuit board 34, and the bottom end of the magnetic field adjusting component 4 abuts against the pressure sensor 5.

[0038] When rotating the magnetic field adjustment component 4, first use an anti-rotation wrench to engage it in the two slots 7 of the base body 1 (refer to...). Figure 4 Next, the hexagonal screwdriver is passed through the clearance hole of the anti-rotation wrench and inserted into the first internal hexagonal slot 6. The hexagonal screwdriver drives the magnetic field adjustment component 4 to rotate. Under the action of the thread, the magnetic field adjustment component 4 is displaced along the axis of the base body 1, causing the pressure value detected by the pressure sensor 5 to change. The control circuit board 34 then adjusts the output current accordingly based on the change in pressure value. The greater the pressure value, the greater the output current; the smaller the pressure value, the smaller the output current, thereby adjusting the magnitude of the electromagnetic field strength.

[0039] The top of the iron core 31 is located inside the magnetic field regulating component 4. A first retaining ring 11 is fixedly installed on the outer wall of the top of the iron core 31, and a second retaining ring 12 is fixedly installed on the inner wall of the magnetic field regulating component 4 near the control circuit board 34. The first retaining ring 11 on the iron core 31 generally cooperates with the second retaining ring 12 on the magnetic field regulating component 4, so that the magnetic field regulating component 4 will not fall off the base body 1.

[0040] Four marking lines 8 are engraved at equal intervals along the circumference of the magnetic field adjustment component 4 on the top end face of the base body 1. The four marking lines 8 are “0”, “1”, “2” and “3” respectively. An indicator line 9 is engraved on the top end face of the magnetic field adjustment component 4. The indicator line 9 is “0”.

[0041] The implementation principle of the electromagnetic bone-integrating healing abutment structure in this application embodiment is as follows: Following the traditional implantation process, the implant is inserted into the patient's alveolar bone. Then, an anti-rotation wrench is used to screw the abutment body 1 into the implant's internal hole. After screwing it into the appropriate position, a hexagonal screwdriver is passed through the clearance hole of the anti-rotation wrench to rotate the magnetic field adjustment component 4. The initial position of the magnetic field adjustment component 4 is that the etched line 0 aligns with the etched line 0 on the abutment body 1. At this time, the control circuit board 34 is in a powered-off state. Rotating the magnetic field adjustment component 4 clockwise activates the control circuit board 34. When the etched line 0 on the magnetic field adjustment component 4 is rotated to align with the etched lines 1, 2, and 3, the control circuit board 34 generates a gradually increasing current. The coil 32 emits an electromagnetic field with a gradually increasing frequency, which can be applied to patients of different ages (young patients with good alveolar bone quality rotate to align with etched line 1, middle-aged patients with average alveolar bone quality rotate to align with etched line 2, and elderly patients with poor alveolar bone quality rotate to align with etched line 3). After osseointegration is completed, the healed abutment is removed, and the abutment and crown are installed according to the traditional procedure to complete the implant surgery.

[0042] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
