[0077] 1 and 4 , the implant system 100 includes an implant 110 , an abutment 120 , a central screw 130 , and a denture 140 .

[0078] An assembly hole is provided at the top of the implant 110, and a screw hole is provided on the bottom wall of the assembly hole. The base 120 cooperates with the assembly hole. The base 120 is provided with an inner cavity 121 that passes through from top to bottom. The central screw 130 is passed through the inner cavity 121. The central screw 130 passes through the inner cavity 121 of the base 120 and is connected to the screw hole of the implant 110. The central screw 130 connects the base 120 and the implant 110 together. The head of the central screw 130 is provided with a screw groove. The shape of the screw groove can be a polygonal groove, a straight groove, a cross groove, etc. The denture 140 is installed on the outside of the base 120. The denture 140 closes the top of the base 120, and a cavity is formed between the top of the inner cavity 121 of the base 120 and the head of the central screw 130.

[0079] 1 to 8 , the implant system monitoring device of the present application is implemented as follows:

[0080] 2 and 3 , the implant system monitoring device includes a joint 200 , an internal fixator 300 , an external fixator 400 , an elastic member 500 , a measuring assembly 600 , and a control board 700 .

[0081] The bottom shape of the joint 200 matches the screw groove shape of the head of the central screw 130 . The inner fixing frame 300 is connected to the top of the joint 200 . The outer fixing frame 400 is disposed around the outer periphery of the inner fixing frame 300 .

[0082] The external fixator 400 can rotate relative to the internal fixator 300 and move in the vertical and horizontal directions. The elastic member 500 is connected between the internal fixator 300 and the external fixator 400. The elastic force of the elastic member 500 makes the external fixator 400 tend to return to its original position.

[0083] The measurement assembly 600 includes a first component 610 , a second component 620 , and a measurement module.

[0084] The first component 610 is mounted on the internal fixation frame 300 , and the second component 620 is mounted on the external fixation frame 400 . The second component 620 is opposite to the first component 610 . The measurement module outputs different signals according to the distance or posture change between the first component 610 and the second component 620 .

[0085] The control board 700 is electrically connected to the measurement module. The control board 700 has a battery 710. The battery 710 provides the control board 700 and the measurement module with power required for operation. The control board 700 receives and stores signals sent by the measurement module.

[0086] 1 and 4 , the implant system monitoring device is installed in the inner cavity 121 of the base 120 , and the implant system monitoring device is located above the central screw 130 . Finally, the denture 140 is installed on the outside of the base 120 , and the denture 140 seals the top of the inner cavity 121 , so that the implant system monitoring device is enclosed in the sealed inner cavity 121 .

[0087] 4 , the bottom of the joint 200 is inserted into the screw groove of the head of the central screw 130 , and the inner fixing frame 300 , the joint 200 , and the central screw 130 are connected together, and the inner fixing frame 300 , the joint 200 , and the central screw 130 are linked.

[0088] The outer wall of the external fixator 400 abuts against the inner wall of the inner cavity 121 . The external fixator 400 is linked to the base 120 . An elastic member 500 is disposed between the external fixator 400 and the internal fixator 300 .

[0089] When the user uses the implant system 100 for biting, the denture 140 is used for chewing, and the denture 140 drives the base 120 to deform. After the base 120 is deformed, the external fixator 400 moves relative to the internal fixator 300, thereby changing the distance or posture of the second part 620 of the measuring component 600 relative to the first part 610, and the measuring module outputs a signal to the control board 700; due to the difference in bite force, the distance change of the second part 620 relative to the first part 610 is different, so the signal output by the measuring module is also different. The occlusal state of the implant system 100 can be judged by this signal, for example, the size of the bite force can be judged by the difference in the output signal, thereby monitoring the operating state of the implant system 100 in real time.

[0090] When the bite force of the denture 140 is removed, the elastic force of the elastic member 500 pushes the external fixator 400 back to its original position, and the second component 620 returns to its original position, so that the signal output by the measurement module returns to its original state or stops outputting the signal.

[0091] In some embodiments, as shown in FIG. 2 and FIG. 3 , a plurality of first components 610 are spaced apart on the inner fixator 300 , an outer fixator 400 is disposed around the outer circumference of the inner fixator 300 , and a plurality of second components 620 are spaced apart on the outer fixator 400 , and the plurality of first components 610 and the plurality of second components 620 are disposed one-to-one opposite to each other.

[0092] When the external fixator 400 deforms with the deformation of the base 120, the multiple second components 620 on the external fixator 400 change position, and the distance or position between the relative first component 610 and the second component 620 changes. The deformation direction and magnitude of the base 120 cause the second components 620 at different positions to move at different distances and directions relative to the relative first component 610.

[0093] For example, if the base 120 drives the external fixator 400 to tilt to the left, the second component 620 on the left side of the external fixator 400 moves leftward toward the opposite first component 610, that is, the distance between the second component 620 on the left side and the first component 610 decreases, while the right side of the external fixator 400 moves leftward away from the opposite first component 610, that is, the distance between the second component 620 on the right side and the first component 610 increases. The measurement module measures that the distance between the second component 620 on the left side and the first component 610 decreases and the distance between the second component 620 on the right side and the first component 610 increases. Therefore, the measurement module can determine that the base 120 is tilted to the left based on the changes in the distances between the first component 610 and the second component 620 at different positions.

[0094] Therefore, the measuring module determines the degree of inclination of the base 120 according to the distance from the first part 610 to the second part 620 at different positions, determines the direction of the occlusal force exerted on the denture 140 by the inclination direction, and determines the magnitude of the occlusal force exerted on the denture 140 by the inclination angle.

[0095] Due to the difference in bite force, the distance change of the second part 620 relative to the first part 610 is different, so the signal output by the measurement module is also different. The bite state of the implant system 100 can be judged by this signal, thereby monitoring the operating state of the implant system 100 in real time.

[0096] In some embodiments, as shown in Figures 2 and 3, a first component 610 is provided on the top of the internal fixator 300, and a second component 620 is provided on the top of the external fixator 400. A plurality of first components 610 are evenly spaced along the circumference of the internal fixator 300, and a plurality of second components 620 are evenly spaced along the circumference of the external fixator 400.

[0097] When the base 120 drives the external fixator 400 to move downward, the second component 620 on the upper side of the external fixator 400 moves downward toward the first component 610 relative thereto. That is, the distance between the upper second component 620 and the first component 610 decreases. The measurement module measures that the distance between the upper second component 620 and the first component 610 decreases. Moreover, the second component 620 on the side wall of the external fixator 400 moves downward and becomes offset from the first component 610. Therefore, the measurement module can determine that the base 120 has moved downward based on the distance between the first component 610 and the second component 620 at different positions.

[0098] In some embodiments, as shown in FIG. 4 and FIG. 5 , the control board 700 further includes a wireless charging module 720 . The battery 710 provides power to the measurement module and the control board 700 , and the wireless charging module 720 wirelessly charges the battery 710 .

[0099] The wireless charging module 720 provides wireless charging for the battery. After the battery 710 runs out of power, the battery 710 is directly wirelessly charged without the need to disassemble the denture 140 to replace the implant system monitoring device in the inner cavity 121.

[0100] In some embodiments, as shown in Figures 2 and 3, the measuring component 600 is a capacitance meter, the first component 610 and the second component 620 are plates, the measuring module is electrically connected to the first component 610 and the second component 620, and the distance difference between the first component 610 and the second component 620 causes the capacitance measured by the measuring module to change.

[0101] When the second component 620 changes position as the base 120 deforms, and the second component 620 moves relative to the first component 610, the distance and relative area between the second component 620 and the first component 610 change. The measurement module then measures the capacitance change between the first component 610 and the second component 620, so that the user can monitor the bite force applied to the denture 140 through the capacitance change.

[0102] In some embodiments, as shown in FIG6 , the measuring component 600 is an induction current meter, the first component 610 is a permanent magnet, the second component 620 is a conductive coil, the second component 620 is electrically connected to the measuring module, and the measuring module measures the change in the induced current.

[0103] When the second component 620 changes position as the base 120 deforms, and the second component 620 moves relative to the first component 610, the distance and relative area between the second component 620 and the first component 610 change, and the second component 620 moves relative to the first component 610 to cut the magnetic flux lines, causing the second component 620 to generate an induced current. The measurement module measures the change in the induced current of the second component 620. The greater the induced current, the greater the movement of the second component 620 relative to the first component 610, so that the user can monitor the bite force exerted on the denture 140 through the change in the induced current.

[0104] In some embodiments, as shown in FIG7 , the measuring component 600 is a magnetic field strength meter, the first component 610 is a permanent magnet, the second component 620 is a Hall sensor, the second component 620 is electrically connected to the measuring module, and the measuring module measures changes in magnetic field strength.

[0105] When the second component 620 changes position as the base 120 deforms, and the second component 620 moves relative to the first component 610, the distance and relative area between the second component 620 and the first component 610 change. That is, the second component 620 changes its position in the magnetic field emitted by the first component 610, causing the magnetic field strength measured by the second component 620 to change. The measuring module reads the magnetic field strength measured by the second component 620, so that the user can monitor the bite force exerted on the denture 140 through the change in magnetic field strength.

[0106] In some embodiments, as shown in Figure 8, the measuring component 600 is a voltage meter, the first component 610 protrudes from the outside of the inner fixation frame 300, the second component 620 is a piezoelectric sheet, the first component 610 abuts against the second component 620, the measuring module is electrically connected to the second component 620, and the measuring module measures the change in voltage.

[0107] When the second component 620 changes position as the base 120 deforms, and the second component 620 moves relative to the first component 610, the first component 610 squeezes the second component 620 to cause the second component 620 to deform, and the second component 620 generates an electric charge, so that the measurement module can measure the voltage. The greater the deformation of the second component 620, the higher the voltage it generates, so that the user can monitor the bite force exerted on the denture 140 through the change in voltage.

The bottom end of the inner wall of the inner hole of the external fixer 400 is provided with a protrusion extending inward, which cooperates with the groove on the outer wall of the lower elastic member 500 to limit the freedom of rotation of the external fixer 400 relative to the lower elastic member 500 around the vertical axis, and the elastic force of the two elastic members makes the external fixer 400 tend to return to its original position.

[0112] The side wall of the external fixator 400 is provided with a plurality of slots extending horizontally therethrough. The slots are evenly spaced along the circumference of the external fixator 400 . The slots are arranged one by one opposite to the arc-shaped slots.

[0114] All the first components 610 and all the second components 620 are electrically connected to a measuring module, and the measuring module measures the capacitance change between each set of opposite first components 610 and second components 620 .

[0115] The control board 700 is disposed on top of the external fixing frame 400 and is electrically connected to the measurement module. The measurement module converts the capacitance changes measured between all relative first components 610 and second components 620 into electrical signals and transmits them to the control board 700. A battery 710 is provided on top of the control board 700 to provide power to the control board 700 and the measurement assembly 600.

[0116] A wireless communication module can be set in the control board 700 so that the control board 700 can send the stored capacitance data to a terminal, such as a computer, laptop, tablet computer, smart watch, mobile phone or other device, so that the user can view it through the terminal.

[0117] A wireless charging module 720 is provided on top of the battery 710 , and the wireless charging module 720 provides a wireless charging function for the control board 700 .

[0118] A sealing cover is provided on the top of the wireless charging module 720 .

[0119] The implant system monitoring device is installed in the inner cavity 121 of the base 120, the bottom of the connector 200 is inserted into the screw groove of the head of the central screw 130, the sealing cover on the top of the wireless charging module 720 closes the top of the inner cavity 121, the denture 140 is mounted on the outside of the base 120, the denture 140 closes the top of the base 120, and the outer wall of the external fixator 400 is against the inner wall of the inner cavity 121.

[0120] When the user uses the implant system 100 and chews food with the denture 140, the denture 140 is deformed by the bite force, and the denture 140 drives the base 120 to deform, while the central screw 130 and the implant 110 are fixed in the alveolar bone. The deformation of the central screw 130 and the implant 110 is smaller than the deformation of the base 120.

[0121] Therefore, deformation of the base 120 causes the external fixator 400 to move or twist, and the distance or position between the multiple sets of opposing second components 620 and the first component 610 on the external fixator 400 changes. Therefore, the measurement module measures the change in capacitance between the multiple sets of opposing second components 620 and the first component 610 and sends the multiple changed capacitances to the control board 700 for storage.

[0122] When the base 120 drives the external fixator 400 to tilt to one side, the distance between the second component 620 and the first component 610 closer to the tilted side of the external fixator 400 becomes smaller, and the capacitance between the second component 620 and the first component 610 closer to the tilted side increases, thereby causing the multiple capacitances to decrease from the tilted direction away from the tilted side. Based on this principle, the control board 700 uses the direction of the maximum capacitance as the direction of the occlusal force borne by the denture 140.

[0123] Furthermore, the greater the bite force on the denture 140, the greater the tendency of the base 120 to drive the external fixator 400 to tilt, and the greater the capacitance between the second component 620 and the first component 610 close to the tilted side. Therefore, the magnitude of the bite force and the magnitude of the capacitance are correlated with each other. Based on this principle, the control board 700 correlates the capacitance with the bite force.

[0124] If a slight crack appears in the implant system 100, causing the structural strength to decrease, the base 120 drives the external fixator 400 to tilt to one side more, causing the capacitance to increase abnormally. The user can determine that the implant system 100 is damaged based on the rapid change in capacitance.

[0125] The control panel 700 has a built-in wireless communication module, which sends the above-mentioned bite force information to the user's terminal through the wireless communication module, so that the user can monitor the size and direction of the bite force borne by the implant system 100 in real time, and monitor the operating status of the implant system 100.

[0126] Specifically, as shown in FIG6 , the implant system monitoring device of the present application makes the following second embodiment:

[0127] The difference between the second embodiment and the first embodiment lies in the internal fixation frame 300 and the measuring assembly 600 .

[0128] The measuring assembly 600 is an induction current meter. The first component 610 is a permanent magnet. The first component 610 is arranged on the top of the inner fixing frame 300. The two magnetic poles of the first component 610 are respectively on the upper and lower sides. The outer shape of the first component 610 is smaller than the inner hole of the outer fixing frame 400. The outer fixing frame 400 is mounted on the outside of the first component 610.

[0129] The second component 620 is a conductive coil. A plurality of second components 620 are disposed on the sidewall of the external fixing frame 400 . All the second components 620 are electrically connected to a measuring module, which detects the induced current of the plurality of second components 620 .

[0130] Deformation of the base 120 causes the external fixator 400 to move or twist, which in turn changes the distance or position between the multiple sets of opposing second components 620 and the first component 610 on the external fixator 400. This causes the multiple second components 620 to generate induced currents. The directions and magnitudes of the multiple induced currents vary, so the measurement module measures the multiple induced currents and transmits them to the control board 700 for storage.

[0131] When the base 120 drives the external fixator 400 to tilt to one side, the swing amplitude between the second component 620 and the first component 610, which is closer to the tilted side of the external fixator 400, is larger, and the magnetic flux of the coil changes more significantly, and thus the induced current is larger. The magnetic flux increases when the coil swings in the direction of approaching the first component 610, and decreases when it swings in the direction of moving away from the first component, thereby generating induced currents in different directions. Based on this principle, the control board 700 integrates the magnitudes and directions of multiple induced currents to form the direction of the occlusal force borne by the denture 140.

[0132] Furthermore, since the greater the bite force exerted on the denture 140, the greater the tilt amplitude of the external fixator 400 driven by the base 120, and the greater the induced current generated by the second component 620, the magnitude of the bite force and the magnitude of the induced current are correlated with each other. Based on this principle, the control board 700 correlates the magnitude of the induced current with the bite force.

[0133] Specifically, as shown in FIG7 , the implant system monitoring device of the present application makes the following third embodiment:

[0134] The difference between the third embodiment and the second embodiment lies in the measuring component 600 .

[0135] The measuring assembly 600 is a magnetic field strength measuring device. The first component 610 is a permanent magnet. The two magnetic poles of the first component 610 are respectively located at the upper and lower sides. The external fixing frame 400 is sleeved on the outside of the first component 610 .

[0136] The second component 620 is a Hall sensor. A plurality of second components 620 are disposed on the side wall of the external fixing frame 400 . All second components 620 are electrically connected to the measurement module. The second components 620 send the measured magnetic field strength to the measurement module.

[0137] When the base 120 is deformed and the external fixator 400 moves or twists, the distance or position between the multiple sets of relative second components 620 and the first component 610 on the external fixator 400 changes, causing the magnetic field strength measured by the multiple second components 620 to change. The directions and magnitudes of the multiple magnetic field strengths are different. Therefore, the measurement module receives multiple magnetic field strength information and sends the multiple magnetic field strength information to the control board 700 for storage.

[0138] When the base 120 drives the external fixator 400 to tilt to one side, the distance between the second component 620 and the first component 610 closer to the tilted side of the external fixator 400 is smaller, and the magnetic field strength of the second component 620 closer to the tilted side is greater, and the magnetic field strength of the second component 620 farther away from the tilted side is smaller. Therefore, the tilt direction of the base 120 and the denture 140 can be determined based on the magnitudes of multiple magnetic field intensities. Based on this principle, the control board 700 integrates the direction of the occlusal force exerted on the denture 140 using multiple magnetic field intensities.

[0139] Furthermore, since the greater the occlusal force exerted on the denture 140, the greater the tendency of the base 120 to drive the external fixator 400 to tilt, the greater the magnetic field strength measured by the second component 620 on the tilted side, the magnitude of the occlusal force and the magnitude of the magnetic field strength are correlated with each other. Based on this principle, the control board 700 correlates the magnitude of the magnetic field strength with the occlusal force.

[0140] Specifically, referring to FIG8 , the implant system monitoring device of the present application makes the following fourth embodiment:

[0141] The fourth embodiment differs from the first embodiment in the internal fixation frame 300 and the measuring assembly 600 .

[0142] The measuring assembly 600 is a voltage measuring device. The first component 610 is a protrusion provided on the outer wall of the inner fixing frame 300. The first component 610 protrudes outward. A plurality of first components 610 are evenly arranged around the outer periphery of the inner fixing frame 300. The outer fixing frame 400 is sleeved on the outer portion of the inner fixing frame 300.

[0143] The second components 620 are piezoelectric sheets. A plurality of second components 620 are disposed on the sidewalls of the external fixation frame 400 . The plurality of first components 610 abut against the plurality of second components 620 in a one-to-one correspondence. All the second components 620 are electrically connected to a measurement module, which detects the voltages of the plurality of second components 620 .

[0144] Deformation of the base 120 causes the external fixator 400 to move or twist, which in turn changes the distance or position between the multiple sets of opposing second components 620 and the first component 610 on the external fixator 400. This causes the multiple second components 620 to be squeezed by the first component 610 and generate voltages. The multiple voltages have different directions and magnitudes, so the measurement module measures multiple voltages and transmits the multiple voltage information to the control board 700 for storage.

[0145] When the base 120 drives the external fixator 400 to tilt to one side, the second component 620 closer to the tilted side of the external fixator 400 is compressed and deformed to a greater extent, and the second component 620 farther away from the tilted side of the external fixator 400 is compressed and deformed to a lesser extent. Based on this principle, the control board 700 integrates the magnitudes of multiple voltages to determine the direction of the occlusal force exerted on the denture 140.

[0146] Furthermore, since the greater the occlusal force exerted on the denture 140, the greater the tendency of the base 120 to drive the external fixator 400 to tilt, and the greater the voltage generated by the second component 620, the magnitude of the occlusal force and the magnitude of the voltage are correlated with each other. Based on this principle, the control board 700 correlates the magnitude of the voltage with the occlusal force.

[0147] 9 to 13 , the implant system monitoring method of the present application is described in the following embodiments:

[0148] The implant system 100 is implanted into a simulated jaw. The simulated jaw can be made based on a three-dimensional scanned model of the user's jaw, or a universal jaw model, so as to simulate the user's chewing using the implant system 100 and more accurately simulate the bite force that the implant system 100 is subjected to.

[0149] The implant system monitoring device is installed into the implant system 100 .

[0150] When pressure is applied to the denture 140 , the denture 140 drives the base 120 to displace or twist relative to the central screw 130 and the implant 110 , causing the second component 620 to move relative to the first component 610 . The measurement assembly 600 outputs a measurement value and records the measurement value corresponding to the pressure.

[0151] By applying pressure to the denture 140 and generating corresponding measurement values, pressures in different directions and / or sizes can output corresponding measurement values, and the measurement values ​​can be associated with the pressure. The bite forces in different directions and / or sizes that the implant system 100 is subjected to during chewing can be simulated through pressure. During the actual use of the implant system 100, the user can judge the bite state of the implant system 100 based on the measurement values, thereby monitoring the operating status of the implant system 100 in real time.

[0152] In some embodiments, the implant system monitoring method further includes an overload fracture monitoring method, which includes the following steps:

[0153] Pressures of different magnitudes and / or directions are applied to the denture 140 to simulate the denture 140 being subjected to bite forces of different magnitudes and / or directions, and the measuring component 600 outputs corresponding measurement values ​​at each pressure, recording the magnitudes, directions and corresponding measurement values ​​of all pressures.

[0154] Since the pressure corresponds to the measured value one by one, an overload database can be established based on the corresponding relationship. Each measured value in the overload database corresponds to a pressure with a certain direction and magnitude.

[0155] An overload threshold is set, which is generally two-thirds of the load limit at which the implant system 100 suffers fracture damage. Pressures exceeding the overload threshold in the overload database are marked as risk values, while pressures not exceeding the overload threshold are marked as safe values.

[0156] The overload database is input into the control board 700 and stored, and the user implants the implant system 100 and installs the implant system monitoring device in the implant system 100 .

[0157] The user chews using the implant system 100 and the denture 140 is subjected to the biting force, and the measuring component 600 measures the actual value.

[0158] The control board 700 finds the measurement value that is the same as the actual value in the overload database and matches it to the corresponding pressure according to the measurement value.

[0159] If the pressure is a risk value, the control panel 700 sends a signal to the terminal, and the user receives the signal through the terminal. The control panel 700 reminds the user through the signal that the pressure on the implant system 100 exceeds two-thirds of the load limit, reminding the user that the implant system 100 is at risk of overload and fracture.

[0160] By pre-simulating the conditions of the implant system 100 under different pressures, the measuring component 600 outputs measurement values ​​corresponding to multiple pressures. Then, when the user uses the implant system 100 to chew, the measuring component 600 outputs the actual value corresponding to the bite force. The corresponding pressure is found by pairing the actual value with the measured value, and the pressure is compared with the overload threshold to remind the user of the risk of overload fracture, so as to facilitate real-time monitoring of the operating status of the implant system 100.

[0161] In some embodiments, the implant system monitoring method further includes a fatigue fracture monitoring method, and the fatigue fracture monitoring method includes the following steps:

[0162] After fixing the implant system 100 to the simulated jaw, repeatedly apply the same pressure to the denture 140, and the direction and magnitude of the pressure change over time. Record the measurement value output by the measuring component 600 when the pressure is maximum. Record the measurement value, repeat the application of the same pressure until the implant system 100 is damaged, and record the number of cycles.

[0163] The curve of the pressure magnitude and / or direction changing with time is changed, the measurement values ​​and cycle numbers corresponding to multiple pressure curves are recorded, and a fatigue database is established based on the corresponding relationship between pressure, measurement values ​​and cycle numbers.

[0164] After inputting the fatigue database into the control panel 700 , the user implants the implant system 100 and installs the implant system monitoring device on the implant system 100 .

[0165] When the user chews using the implant system 100 , the bite force on the denture 140 also changes over time, and the measurement component 600 measures the actual value when the bite force is the maximum.

[0166] The control board 700 matches the measured value with the actual value, finds the measured value corresponding to the actual value in the fatigue database, and then obtains the pressure and cycle number corresponding to the measured value.

[0167] Each time the user bites, the measuring component 600 generates an actual value. The control board 700 then outputs the number of cycles for each bite based on the actual value received. The control board 700 calculates the reciprocal sum based on the number of cycles output for each bite. The remaining service life of the implant system 100 is 1-the reciprocal sum.

[0168] For example, if a 10°, 300N force is applied to the denture, the implant system can cycle 5 times. After one cycle of this force, 4 / 5 of the implant life will remain, and the loss of life is 1 / 5. Similarly, if a 30°, 250N force is applied to the denture, it can cycle 10 times. After one cycle of this force, 9 / 10 of the implant life will remain, and the loss of life is 1 / 10. If chewing is performed twice in a chewing process and the two forces mentioned above are generated respectively, the implant life loss is 1 / 5+1 / 10, which is the sum of the inverse of the number of cycles each time, and the remaining life of the implant is 1-(1 / 5+1 / 10).

[0169] By pre-simulating the pressure that the implant system 100 is subjected to under the user's normal occlusion state, the control panel 700 can obtain the remaining life of the implant system 100 under normal occlusion in real time. If the remaining life of the implant system 100 is insufficient, the control panel 700 can send a signal of insufficient remaining life to the user's terminal, reminding the user to maintain or replace the implant system 100 in time.

[0170] In some embodiments, the implant system monitoring method further includes a screw loosening monitoring method, and the screw loosening monitoring method includes the following steps:

[0171] After the implant system 100 is fixed to the simulated jawbone, the central screw 130 is loosened, and the implant system 100 is put into a loose state. An implant system monitoring device is installed in the implant system 100 .

[0172] Pressure is applied to the denture 140, and the magnitude and / or direction of the pressure changes over time to simulate the actual bite force of the user in the occlusal state. The measurement value of the measuring component 600 changes over time, and the curve of the measurement value changing over time is a loosening curve.

[0173] Then, the loosening state of the implant system 100 is changed by turning the central screw 130 , and pressure is repeatedly applied to the denture 140 , and loosening curves corresponding to multiple loosening states are recorded.

[0174] A loosening database is established based on the correspondence between loosening states and loosening curves.

[0175] The user implants the implant system 100 and installs an implant system monitoring device in the implant system 100 , and inputs the loosening database into the control board 700 .

[0176] The user chews using the implant system 100 , and the curve in which the actual value measured by the measuring component 600 changes with time is the actual curve.

[0177] The control board 700 matches the actual curve with all loosening curves in the loosening database. If the actual curve successfully matches any loosening curve, it proves that the implant system 100 is loose. The control board 700 sends a loosening signal to the user's terminal to remind the user that there is a risk of screw loosening.

[0178] By pre-simulating the implant system 100 in a loose state to withstand the chewing force of the user, the control panel 700 can obtain the loosening curve of the implant system 100 in a loose state in real time. If the actual curve of the occlusal output by the user using the implant system 100 matches the loosening curve, the control panel 700 reminds the user that there is a risk of screw loosening in the implant system 100, so that the user can monitor the operating status of the implant system 100 in real time.

[0179] In some embodiments, the implant system monitoring method further comprises a malocclusion monitoring method, the malocclusion monitoring method comprising the following steps:

[0180] The implant system 100 is fixed to a simulated jaw, an implant system monitoring device is installed in the implant system 100, and then the implantation position of the implant 110 or the shape of the denture 140 is changed to put the implant system 100 in a malocclusal or unstable state.

[0181] Pressure is applied to the denture 140 , and the pressure changes over time, simulating the bite force of the user when chewing with the implant system 100 . Then, the measurement value of the measurement component 600 also changes over time, and the curve of the measurement value changing over time is the malocclusion curve.

[0182] Then, the implantation position of the implant 110 or the shape of the denture 140 is changed to change the implant system 100 to a malocclusion or unstable state, and the above-mentioned variable pressure is repeatedly applied to the denture 140 to record malocclusion curves corresponding to multiple malocclusion states.

[0183] A malocclusion database is established according to the correspondence between the malocclusion states and the malocclusion curves.

[0184] The user implants the implant system 100 and installs the implant system monitoring device in the implant system 100 , and inputs the malocclusion database into the control panel 700 .

[0185] The user chews using the implant system 100 , and the actual value measured by the measurement component 600 changes over time. A curve showing the change of the actual value over time is an actual curve.

[0186] The control panel 700 matches the actual curve with all malocclusion curves in the malocclusion database. If the actual curve successfully matches any malocclusion curve, it indicates that the user's implant system 100 has a malocclusion risk.

[0187] By pre-simulating the implant system 100 in a loose state to withstand the chewing force of the user, the control panel 700 can obtain the improper occlusion curve of the implant system 100 in the improper occlusion state in real time. If the actual curve output by the user using the implant system 100 for occlusion matches the improper occlusion curve, the control panel 700 reminds the user that the implant system 100 has a risk of improper occlusion, so that the user can monitor the operating status of the implant system 100 in real time.

[0188] In some embodiments, the simulated jaws are divided into multiple types according to density.

[0189] Since different users have different jaw densities, the simulated jaws are divided into multiple types according to density to match the jaw conditions of different users, so that the implant system 100 can more accurately correspond to the user's actual situation during the pressure simulation process, making the established database more accurate.
