Description

Technical Field

[0001] The present invention relates to the technical field of dentures, and in particular to a device for measuring the adsorption force of complete dentures and a method for using the device. Background Art

[0002] Full dentures are an important restorative method for patients with edentulous teeth to restore chewing function, improve appearance and enhance quality of life. The functionality and comfort of full dentures depend to a large extent on their adsorption force in the oral cavity. Adsorption force refers to the stability between the denture and the soft and hard tissues of the oral cavity formed by the combined action of negative pressure, surface tension and adhesion. It is one of the important indicators for evaluating the adaptability of dentures. Insufficient adsorption force may lead to loosening, falling off of dentures, food impaction and other problems, seriously affecting the patient's daily life; excessive adsorption force may increase the difficulty of removing and wearing dentures, and even cause damage to oral soft tissues. Therefore, accurately measuring the adsorption force of full dentures is of great significance for the design, production and clinical adaptation of dentures.

[0003] At present, the clinical evaluation of the adsorption force of full dentures mainly relies on doctors to manually remove dentures and make subjective judgments on the adsorption force based on experience. However, this evaluation method lacks objectivity and quantitative standards, and it is difficult to accurately reflect the actual adsorption performance of dentures. In addition, there are attempts in existing studies to measure adsorption force by simulating the oral environment in the laboratory. However, this laboratory testing method, which is divorced from clinical reality, cannot be directly applied to clinical practice. It is difficult to truly reflect the adsorption status of dentures in the patient's oral environment, and it cannot provide clinicians with timely and effective diagnosis and treatment references. Therefore, there is an urgent need for a full denture adsorption force detection device that can be operated directly in the patient's mouth to solve the above problems and provide a scientific basis for the design, production and clinical adaptation of dentures.

[0012] Preferably, the tension adjustment assembly includes a workbench 1, the inner wall of the workbench 1 is fixedly connected to a drive motor, the output end of the drive motor is connected to a transmission threaded rod, the outer wall of the transmission threaded rod is threadedly connected to a transmission block, the outer wall of the transmission block is fixedly connected to a slider 2, the outer wall of the transmission block is slidably connected to the inner wall of the workbench 1, the lower surface of the tension sensor is fixedly connected to the upper surface of the transmission block, and the outer wall of the workbench 1 is arranged on the outer wall of the fixed block.

[0013] Preferably, a second slide groove is provided inside the workbench one, and the outer wall of the slider two is slidably connected to the inside of the workbench one through the second slide groove.

[0014] Preferably, a method for using a complete denture adsorption force measuring device comprises the following steps:

[0015] S1. First, the patient wears a denture of appropriate size, then selects a positioning block of appropriate model and inserts it into the surface of the denture. The positioning block is then clamped by the fixing assembly. At this time, the patient is allowed to maintain a natural occlusion state. The tension adjustment assembly is then used to adjust the initial tension of the pull wire. The pull wire obtains a fulcrum through the guide assembly. The patient then slowly opens his mouth, which causes the pull wire to pull the fixing assembly. At the same time, the tension change of the pull wire is recorded and monitored in real time by the tension sensor and fed back to the display screen through the connecting line;

[0016] S2. Rotate the bidirectional threaded rod to drive the push block to move forward and backward. The slider slides under the drive of the push block. The sliding column moves synchronously under the drive of the push block. The sliding column slides under the action of the pressure block. The return spring contracts under the drive of the sliding column, thereby fixing the pressure block on the outside of the positioning block.

[0017] S3. Install the pull wire inside the housing, and wind the pull wire along the grooves preset inside the first, second, and third rotating shafts to guide the pull wire;

[0018] S4. Turn on the drive motor to drive the transmission threaded rod to rotate. The transmission block moves back and forth driven by the transmission threaded rod. The tension sensor and the transmission block move synchronously. As the tension sensor moves, the pull wire connected to the tension sensor is gradually pulled, and then the pull wire assists the denture body to quickly detach.

[0019] Working principle: The patient is asked to wear a denture body of appropriate size, and then a positioning block of appropriate model is selected and installed on the outside of the denture body. The positioning block is then fixed to the surface of the denture body using the fixing component. The patient is then asked to maintain natural occlusion. At the same time, the tension adjustment component is used to provide initial tension for the pull wire, and the guide component provides a pulling fulcrum for the pull wire. The patient then slowly opens his mouth to drive the denture body up and down, and the denture body drives the positioning block, fixing component, and pull wire to move. The pull wire then pulls the fixing component. The tension of the pull wire increases with the increase in the opening and closing amplitude of the patient's mouth. When the tension of the pull wire reaches the maximum adsorption force of the denture body, the denture body is detached from the patient's mouth. During this process, the tension sensor will feed back the tension change of the pull wire to the display screen in real time, so that the doctor can operate directly in the patient's mouth, reflect the patient's actual oral environment, measure the changes in the adsorption force of the denture body in real time, and accurately measure the maximum adsorption force of the denture body, so that the test results have clinical reference value.

[0020] The bidirectional threaded rod is driven to rotate by the rotating column and the friction block, and then the push block moves back and forth driven by the bidirectional threaded rod, and then the slider slides driven by the push block, and then the slide column moves synchronously driven by the push block, and the slide column slides along the inner wall of the push block under the reverse push of the pressure block, and then the return spring is elastically deformed under the drive of the slide column, which makes the pressure blocks at different positions produce corresponding displacement and deformation according to the different positions and shapes of the contact positioning blocks. Because the pressure block is made of sponge material, it will automatically deform and fit to the surface of the positioning block when it contacts the positioning block, thereby ensuring the stability of the denture body during measurement, avoiding the denture body from sliding and falling off during the detection process, and adapting to denture bodies of different shapes and sizes.

[0021] By installing the pull wire inside the shell, and then guiding the pull wire along the preset grooves inside the rotating shaft one, rotating shaft two and rotating shaft three, during this process, the fixed block ensures that the rotating shaft one, rotating shaft two and rotating shaft three remain stable. The direction of the pulling force generated by the guided pull wire is consistent with the direction of the adsorption force of the denture body, thereby achieving the effect of further improving the accuracy of the denture body adsorption force test.

[0022] Turn on the drive motor to drive the transmission threaded rod to rotate, and then the transmission block is driven by the transmission threaded rod to move back and forth. During this process, the transmission block slides smoothly relying on the guiding effect of the slider 2. At the same time, the tension sensor moves synchronously with the transmission block. As the tension sensor moves, the pull wire connected to the tension sensor is gradually pulled, so as to maintain the tension of the pull wire, provide initial tension for the denture body, assist the denture body to fall off from the fitting part, and quickly and accurately measure the maximum adsorption force of the denture body.

[0023] The present invention provides a complete denture adsorption force measurement device and its use method, which has the following beneficial effects:

[0024] 1. The present invention allows the patient to maintain natural occlusion and uses the tension adjustment component to provide initial tension for the pull wire. The pull wire then pulls the fixing component. When the tension of the pull wire reaches the maximum adsorption force of the denture body, the denture body is detached from the patient's mouth. This makes it convenient for the doctor to operate directly in the patient's mouth, reflects the patient's actual oral environment, measures the changes in the adsorption force of the denture body in real time, and accurately measures the maximum adsorption force of the denture body, so that the test results have clinical reference value.

[0025] 2. The present invention drives the bidirectional threaded rod to rotate by rotating the column and the friction block, and then the push block moves back and forth driven by the bidirectional threaded rod, thereby ensuring the stability of the denture body during measurement, avoiding the denture body from sliding or falling off during the detection process, and adapting to denture bodies of different shapes and sizes.

[0026] 3. The present invention installs the pull wire inside the shell and then guides the pull wire along the preset grooves inside the rotating shaft one, the rotating shaft two and the rotating shaft three. The direction of the pulling force generated by the guided pull wire is consistent with the direction of the adsorption force of the denture body, thereby achieving the effect of further improving the accuracy of the adsorption force test of the denture body.

[0027] 4. The present invention turns on the driving motor to drive the transmission threaded rod to rotate, and then the transmission block is driven by the transmission threaded rod to move back and forth, the tension sensor and the transmission block move synchronously, and the pull wire connected to the tension sensor is gradually pulled, so as to maintain the tension of the pull wire, provide initial tension for the denture body, assist the denture body to fall off from the fitting part, and quickly and accurately measure the maximum adsorption force of the denture body.

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Please see the attached Figure 1 , an embodiment of the present invention provides a full denture adsorption force measuring device and a method for using the same, comprising a denture body 1, wherein the outer wall of the denture body 1 is provided with a positioning block 2, the positioning block 2 is connected to a fixing component 3, the fixing component 3 is connected to a pull wire 4, the pull wire 4 is connected to a guide component 5, the guide component 5 is connected to a tension adjustment component 7, the rear outer wall of the pull wire 4 is fixedly connected to a tension sensor 6, the tension adjustment component 7 is connected to a workbench 2 10, the upper surface of the workbench 2 10 is fixedly connected to a display screen 9, the inner wall of the display screen 9 is electrically connected to a connecting wire 8, and the outer wall of the connecting wire 8 is electrically connected to the inner wall of the tension sensor 6;

[0038] Specifically, the patient is fitted with a denture body 1 that fits the patient's mouth shape, the denture body 1 is put on the exposed gum surface of the patient, and then a positioning block 2 of suitable model is selected and put on the surface of the denture body 1, wherein a groove is provided inside the positioning block 2 to accommodate the denture body 1, and the positioning block 2 is made of silicone rubber, which has good biocompatibility and is non-irritating to oral tissue. At the same time, silicone rubber has good elasticity and flexibility and can adapt to different oral tissue forms, and a silicone layer is affixed to the groove inside the positioning block 2, which protects the denture body 1 while improving the patient's comfort, and further fixes the positioning block 2 to the surface of the denture body 1 by using a fixing component 3, at this time allowing the patient to maintain a natural occlusion state, and then uses the tension adjustment component 7 to accurately control the initial tension of the pull wire 4, and then the guide component 5 is for the subsequent tension of the pull wire 4 The pulling provides a fulcrum, and then the patient slowly opens his mouth to drive the denture body 1 to move up and down. Since the denture body 1, positioning block 2, fixing component 3 and pull wire 4 are connected in sequence, the denture body 1 drives the positioning block 2, fixing component 3 and pull wire 4 to move. At this time, the pull wire 4 is straightened and pulls the fixing component 3 in the opposite direction. When the tension of the pull wire 4 reaches the maximum adsorption force of the denture body 1, the denture body 1 is detached from the patient's mouth. During this process, the tension sensor 6 converts the tension change of the pull wire 4 into an electrical signal and inputs it to the display screen 9 through the connecting line 8. The doctor can observe the adsorption force change trend of the denture body 1 in real time and record the maximum adsorption force when the denture body 1 is detached, so as to facilitate the doctor to operate directly in the patient's mouth, reflect the patient's actual oral environment, and make the test results have clinical reference value.

[0039] See attached Figure 2 -Attached Figure 4 The fixing assembly 3 includes a shell 301, the inner wall of the shell 301 is threadedly connected to a bidirectional threaded rod 302, the right outer wall of the bidirectional threaded rod 302 is provided with a rotating structure, the left outer wall of the bidirectional threaded rod 302 is threadedly connected to a push block 305, the lower surface of the push block 305 is provided with a limiting structure 1, the inner wall of the push block 305 is provided with a limiting structure 2, and the limiting assembly 2 is connected to a pressing block 307;

[0040] Specifically, the bidirectional threaded rod 302 is driven to rotate inside the shell 301 by the rotating structure, and then the push block 305 is opened and closed by the bidirectional threaded rod 302, and then the push block 305 is driven by the limiting structure one to move along the specified trajectory. At this time, the limiting structure two drives the pressure block 307 to fit the surface of the positioning block 2. Since the pressure block 307 is made of sponge, the sponge will automatically deform and fit to the surface of the positioning block 2 when it contacts the positioning block 2. Since the positioning block 2 is made of silicone rubber, the positioning block 2 will automatically deform and fit to the surface of the denture body 1 when it is under pressure, thereby ensuring the stability of the denture body 1 during measurement, avoiding the denture body 1 from sliding or falling off during the detection process, and adapting to denture bodies 1 of different shapes and sizes.

[0041] See attached Figure 2 The rotating structure includes a rotating column 303, the outer wall of the rotating column 303 is fixedly connected to the outer wall of the bidirectional threaded rod 302, and the outer wall of the rotating column 303 is fixedly connected to the friction block 304;

[0042] Specifically, a rotating column 303 is installed on the outer wall of the bidirectional threaded rod 302, and friction blocks 304 are evenly installed on the outer wall of the rotating column 303 to increase friction and prevent the doctor from slipping. The rotating column 303 and the friction blocks 304 make it convenient for the doctor to rotate the bidirectional threaded rod 302.

[0043] See attached Figure 3 The limiting structure 1 includes a slider 1 308, the upper surface of the slider 1 308 is slidably connected to the lower surface of the push block 305, and a slide groove 1 309 is opened inside the housing 301, and the outer wall of the slider 1 308 is slidably connected to the inside of the housing 301 through the slide groove 1 309;

[0044] Specifically, since the push block 305 is fixedly connected to the slider 1 308 , the slider 1 308 slides inside the housing 301 through the slide groove 1 309 driven by the push block 305 .

[0045] See attached Figure 4 The second limiting structure includes a sliding column 306, the outer wall of the sliding column 306 is slidably connected to the inner wall of the push block 305, the inner wall of the push block 305 is provided with a return spring 310, the outer wall of the return spring 310 is provided on the inner wall of the sliding column 306, the outer wall of the sliding column 306 is fixedly connected to the pressure block 307, and the outer wall of the pressure block 307 is provided on the outer wall of the positioning block 2;

[0046] Specifically, since the push block 305 is connected to the sliding column 306, the sliding column 306 moves synchronously under the drive of the push block 305, and the sliding column 306 is fixedly connected to the pressure block 307. When the pressure block 307 contacts the positioning block 2, the sliding column 306 slides along the inner wall of the push block 305 under the reverse push of the pressure block 307. Since the sliding column 306 is fixedly connected to the return spring 310, the return spring 310 undergoes elastic deformation under the drive of the sliding column 306, which causes the pressure blocks 307 at different positions to produce corresponding displacements and deformations according to the different positions and shapes of the contact positioning block 2.

[0047] See attached Figure 5The guide assembly 5 includes a fixed block 501, the front outer wall of the fixed block 501 is fixedly connected to the rotating shaft 1 502, the middle outer wall of the fixed block 501 is fixedly connected to the rotating shaft 2 503, and the rear outer wall of the fixed block 501 is fixedly connected to the rotating shaft 3 504; the outer wall of the pull wire 4 is arranged on the side wall of the rotating shaft 1 502, the outer wall of the pull wire 4 is arranged on the side wall of the rotating shaft 2 503, and the outer wall of the pull wire 4 is arranged on the side wall of the rotating shaft 3 504;

[0048] Specifically, by installing the pull wire 4 inside the shell 301, and guiding the pull wire 4 along the grooves opened inside the rotating shaft 1 502, the rotating shaft 2 503 and the rotating shaft 3 504, wherein the fixed block 501 maintains the stability of the rotating shaft 1 502, the rotating shaft 2 503 and the rotating shaft 3 504, and the pulling force generated by the pull wire 4 after being guided is consistent with the direction of the adsorption force of the denture body 1, thereby achieving the effect of ensuring the accuracy of the adsorption force test of the denture body 1.

[0049] See attached Figure 6 and attached Figure 7 The tension adjustment assembly 7 includes a workbench 701, the inner wall of the workbench 701 is fixedly connected to a drive motor 702, the output end of the drive motor 702 is connected to a transmission threaded rod 703, the outer wall of the transmission threaded rod 703 is threadedly connected to a transmission block 704, the outer wall of the transmission block 704 is fixedly connected to a slider 2 705, the outer wall of the transmission block 704 is slidably connected to the inner wall of the workbench 1 701, the lower surface of the tension sensor 6 is fixedly connected to the upper surface of the transmission block 704, and the outer wall of the workbench 1 701 is arranged on the outer wall of the fixed block 501; a slide groove 2 706 is opened inside the workbench 1 701, and the outer wall of the slider 2 705 is slidably connected to the inside of the workbench 1 701 through the slide groove 2 706;

[0050] Specifically, the drive motor 702 is started to drive the transmission threaded rod 703 to rotate inside the workbench 1 701, and then the transmission block 704 moves back and forth driven by the transmission threaded rod 703. Since the slider 2 705 is fixedly connected to the transmission block 704, the transmission block 704 slides along the slide groove 2 706 driven by the slider 2 705, which prevents the transmission block 704 from being offset. Since the tension sensor 6 is fixedly connected to the transmission block 704, the tension sensor 6 moves synchronously driven by the transmission block 704. Since the pull wire 4 is fixedly connected to the tension sensor 6, the pull wire 4 is pulled by the tension sensor 6, thereby achieving the effect of causing the pull wire 4 to be in a taut state and providing initial tension to assist the denture body 1 to fall off so as to quickly measure the maximum adsorption force of the denture body 1.

[0051] See attached Figure 1 -Attached Figure 7A method for using a complete denture adsorption force measuring device comprises the following steps:

[0052] S1. First, the patient wears the denture body 1 of appropriate size, then selects the positioning block 2 of appropriate model and inserts it into the surface of the denture body 1. The positioning block 2 is then clamped by the fixing assembly 3. At this time, the patient is allowed to maintain a natural occlusion state. Then, the tension adjustment assembly 7 is used to adjust the initial tension of the pull wire 4. The pull wire 4 obtains a fulcrum through the guide assembly 5. Then, the patient slowly opens his mouth, which causes the pull wire 4 to pull the fixing assembly 3. At the same time, the tension change of the pull wire 4 is recorded and monitored in real time by the tension sensor 6 and fed back to the display screen 9 through the connecting line 8;

[0053] S2. Rotate the bidirectional threaded rod 302 to drive the push block 305 to move forward and backward. The slider 1 308 slides under the drive of the push block 305. The slide column 306 moves synchronously under the drive of the push block 305. The slide column 306 slides under the action of the pressure block 307. The return spring 310 contracts under the drive of the slide column 306, thereby fixing the pressure block 307 on the outside of the positioning block 2.

[0054] S3. Install the pull wire 4 inside the housing 301. Wind the pull wire 4 along the grooves preset inside the rotating shaft 1 502, the rotating shaft 2 503, and the rotating shaft 3 504 to guide the pull wire 4.

[0055] S4. Turn on the drive motor 702 to drive the transmission threaded rod 703 to rotate. The transmission block 704 moves back and forth driven by the transmission threaded rod 703. The tension sensor 6 moves synchronously with the transmission block 704. As the tension sensor 6 moves, the pull wire 4 connected to the tension sensor 6 is gradually pulled, and then the pull wire 4 assists the denture body 1 to quickly detach.
