Abstract
Description
Technical Field
[0001] This invention relates to the field of dental diagnostic tools, and more specifically, to an intelligent periodontal subgingival scaling training device. Background Technology
[0002] Currently, subgingival scaling and root planing is an essential skill for every dentist treating different surfaces of all teeth. However, most subgingival scaling instruments used in current procedures rely heavily on the dentist's experience and tactile sense, which has the following drawbacks:
[0003] 1) Existing subgingival curettes cannot provide real-time positioning feedback, making it difficult for trainees to accurately judge whether their subgingival curette is used in the correct area or has reached the bottom of the periodontal pocket, resulting in insufficient accuracy of probing operations.
[0004] 2) The lack of guidance on the probing angle of the curette makes it impossible for the subgingival curette, especially when measuring the proximal surfaces of teeth, to always maintain the optimal angle that is close to the contact point and slightly tilted towards the center of the proximal surface;
[0005] 3) Lack of judgment regarding the probing force of the subgingival curette;
[0006] 4) The movement trajectory of the subgingival curette cannot be visualized. Traditional methods cannot show the movement trajectory of the subgingival curette in trainees.
[0007] Therefore, there is an urgent need for a training model based on intelligent periodontal subgingival scaling teaching, so that beginners can receive systematic probing training and facilitate people to train on the area, depth, angle and control force of the subgingival scaling instrument.
[0008] The information disclosed in the background section is only intended to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention
[0009] This invention provides an intelligent periodontal subgingival scaling training device to solve the problems mentioned in the background art.
[0010] One technical solution provided in this embodiment of the invention is an intelligent periodontal subgingival scaling training device, comprising: a dental oral model, a subgingival scaling instrument group, and a processing module;
[0011] The dental oral model includes a gingival model, and a dental model is placed on the periodontal pocket of the gingival model. The gingival model is connected to the top of the dental model, and the peripheral veneers are separated. A first micro-sensor is placed inside the dental model.
[0012] The subgingival curettage tool group includes various models of subgingival curettage tools. The different models of subgingival curettage tools have different areas of use. Both ends of the subgingival curettage tool are working ends, and the working ends on both sides have different areas of use. The tip of the working end is provided with a second micro sensor and a pressure sensor. The second micro sensor is connected to the first micro sensor.
[0013] The processing module connects the dental oral model and the subgingival curette assembly. It receives and processes signals from the first microsensor, the model of the subgingival curette, the second microsensor, and the pressure sensor. By calculating the relative positions of the first microsensor and the second microsensor corresponding to different models of the subgingival curette, and combining the measurement data obtained by the pressure sensor, it determines the relative position of the working end of the subgingival curette to the bottom of the periodontal pocket, and judges whether the application area of the working end of the subgingival curette is correct. It determines the angle of the subgingival curette by calculating the relative angle between the first microsensor and the second microsensor, and determines the application force of the subgingival curette based on the measurement data obtained from the pressure sensor signal.
[0014] The beneficial effects of this invention are:
[0015] By using a first micro-sensor placed inside the tooth model in the dental oral model, a second micro-sensor placed at the working end of the subgingival curette, and a built-in processing module, the real-time monitoring and processing of the tip position and angle of the subgingival curette is achieved. This allows the user to know the correct area, depth, and angle of probing, avoid deviations, and thus complete the training correctly.
[0016] The pressure sensor and processing module installed at the working end of the subgingival curette enable real-time monitoring and feedback of the application force of the curette, allowing users to adjust the application force accordingly and thus complete the training correctly.
[0017] The above description of the invention is merely an overview of the technical solution of the present invention.

[0029] The following describes an intelligent periodontal subgingival scaling training device according to an embodiment of the present invention, with reference to the accompanying drawings.
[0030] This invention provides an intelligent periodontal subgingival scaling training device, the device comprising:
[0031] Dental oral model, subgingival curette assembly and processing module 30;
[0032] The dental oral model includes a gingival model 11, and a tooth model 12 is positioned in the periodontal pocket of the gingival model 11. The tops of the gingival model 11 and the tooth model 12 are connected, while the peripheral veneers are separate. A first microsensor 13 is installed inside the tooth model 12. The subgingival curettage kit includes various models of subgingival curettage instruments 20, each with a different application area, such as... Figure 1 and Figure 2 As shown, both ends of the subgingival curette 20 are working ends 21. The working ends 21 on both sides have different areas of use. Since the curette has tooth position specificity and tooth surface specificity, different working ends 21 are suitable for different tooth surfaces and positions of different teeth. The tip of the working end 21 is provided with a second micro sensor 22 and a pressure sensor. The second micro sensor 22 is connected to the first micro sensor 13.
[0033] The processing module 30 connects the dental oral model and the subgingival curette assembly. It receives and processes signals from the first microsensor 13, the model of the subgingival curette 20, the second microsensor 22, and the pressure sensor 23. By calculating the relative positions of the first microsensor 13 and the second microsensor 22 corresponding to different models of subgingival curette 20, and combining the measurement data obtained by the pressure sensor 23, it determines the relative position of the working end 21 of the subgingival curette 20 to the bottom of the periodontal pocket, and judges whether the application area of the working end 21 of the subgingival curette 20 is correct. By calculating the relative angle between the first microsensor 13 and the second microsensor 22, it determines the angle of the subgingival curette 20. Based on the measurement data obtained from the signal of the pressure sensor 23, it determines the application force of the subgingival curette 20.
[0034] In the above embodiments, the intelligent periodontal subgingival scaling training device provided in this application realizes real-time monitoring and processing of the tip position and usage angle of the subgingival scaling device 20 through the first micro-sensor 13 set inside the tooth model 12 in the dental oral model, the second micro-sensor 22 set at the working end 21 of the subgingival scaling device 20, and the built-in processing module 30. This allows the user to know the correct usage area, correct depth and usage angle of the periodontal subgingival scaling device 20, avoid deviations, and thus complete the training correctly.
[0035] The pressure sensor 23 and processing module 30 installed at the working end 21 of the subgingival curette 20 enable real-time monitoring and feedback of the application force of the subgingival curette 20, allowing the user to adjust the application force of the subgingival curette 20 accordingly and thus complete the training correctly.
[0036] In a preferred embodiment, the first micro sensor 13 is provided with a first tag, and a mapping relationship is established between the first tag information and the corresponding tooth model 12 information, so that the processing module 30 can obtain the corresponding tooth model 12 information by obtaining the first tag information, and the tooth model 12 information includes a preset depth range.
[0037] The second micro-sensor 22 is equipped with a second tag, and a mapping relationship is established between the second tag information and the corresponding working end 21 information, so that the processing module 30 can obtain the corresponding working end 21 information by obtaining the second tag information. The working end 21 information includes: the model of the subgingival curette 20 where the working end 21 is located, the first preset use area corresponding to the subgingival curette 20, and the second preset use area corresponding to the working end 21. The second preset use area includes the first preset position range or the second preset position range of the tooth model 12 within the first preset use area.
[0038] The information of the tooth model 12 also includes the tooth model 12 model and the preset position range of the teeth, which includes a first preset position range and a second preset position range.
[0039] The information of the working end 21 also includes: the type of the working end 21, which corresponds to the second preset use area. For example, the types of the working ends 21 on both sides of the subgingival curette 20 are different, which can be recorded as one side working end 21 and the other side working end 21. The same working end 21 cannot be used to process the same use area. Therefore, the second preset use area corresponding to the working end 21 is set in the second label of the second micro sensor 22 in the working end 21.
[0040] like Figure 5 As shown, the processing module 30 includes:
[0041] The receiving unit is used to receive signals from the first micro sensor 13, the second micro sensor 22 and the pressure sensor 23. The signal of the first micro sensor 13 contains first tag information and the signal of the second micro sensor 22 contains second tag information.
[0042] The relative position calculation unit, connected to the receiving unit, determines one or two first microsensors 13 with the shortest distance to the second microsensor 22 by calculating the relative position between each first microsensor 13 and the second microsensor 22 corresponding to the subgingival curette 20. It uses the measurement data of the pressure sensor 23 to determine the first microsensor 13 with the shortest distance to the second microsensor 22. Based on the relative position between the nearest first microsensor 13 and the second microsensor 22 corresponding to the subgingival curette 20, it determines the relative position between the working end 21 of the subgingival curette 20 and the bottom of the periodontal pocket.
[0043] When the working end 21 is exactly between two teeth, the method of obtaining the nearest first microsensor 13 by calculating the relative position between each first microsensor 13 and the second microsensor 22 corresponding to the subgingival curvature 20 will obtain the two first microsensors 13 with the shortest distance. At this time, due to the presence of the gingiva, the measurement data of the pressure sensor 23 can be obtained to help confirm the nearest first microsensor 13, thereby determining the relative position of the working end 21 of the subgingival curvature 20 and the periodontal pocket bottom of the tooth model 12 where the nearest first microsensor 13 is located.
[0044] It should be noted that when the position is close to the applied pressure, it indicates that this is the tooth surface of the target tooth where the operator wishes to apply treatment, thus enabling the measurement data from the pressure sensor to help confirm the nearest first micro-sensor.
[0045] The area determination unit, connected to the relative position calculation unit, determines whether the application area of the working end 21 of the subgingival curette 20 is correct based on the relative position of the working end 21 of the subgingival curette 20 to the bottom of the periodontal pocket. Specifically, this includes:
[0046] The model determination component obtains the first preset usage area of the corresponding model of the subgingival curette 20 based on the received second tag information, and determines whether the usage area of the working end 21 of the current subgingival curette 20 is within the first preset usage area of the current subgingival curette 20 based on the relative position.
[0047] Among them, such as Figure 3 and Figure 4 As shown, the first preset usage area includes: anterior tooth area A, buccal and lingual surfaces of posterior teeth area B, mesial surface of posterior teeth area C, and distal surface of posterior teeth area D;
[0048] In the above embodiments, the subgingival curette 20 can be a periodontal Gracey curette, and the model may include:
[0049] #5-6: Applicable to anterior tooth region A;
[0050] #7-8: Applicable to buccal and lingual surfaces of the posterior teeth (B);
[0051] #11-12: Applicable to the mesial surface C of the posterior tooth region;
[0052] #13-14: Applicable to the distal surface D of the posterior tooth region.
[0053] Among them, the present invention patent includes, but is not limited to, the scraper of the above-mentioned model.
[0054] For example, the subgingival curette 20 of model 5 is used to treat the anterior tooth region A. The second label of the second microsensor 22 of the subgingival curette 20 of model 5 is G5. The second label information indicates that the first preset use area of the subgingival curette 20 of the corresponding model is the anterior tooth region A. The first labels of the first microsensors 13 in the tooth model 12 of the anterior tooth region A are Y1, Y2, Y3, and Y4, respectively. When the relative distance between the second microsensor 22 of the subgingival curette 20 of model 5 and the first microsensors 13 corresponding to Y1, Y2, Y3, and Y4 is within the preset distance, it is determined that the use area of the working end 21 of the current subgingival curette 20 is within the first preset use area of the required model of subgingival curette 20. Otherwise, it is not.
[0055] The working end judgment component is connected to the model judgment component. Based on the received second label information, it obtains the second preset use area of the corresponding working end 21 and judges whether the relative position of the working end 21 of the subgingival curette 20 and the bottom of the periodontal pocket is within the second preset use area.
[0056] The second preset usage area includes either the first preset location range or the second preset location range;
[0057] like Figure 4 As shown, the second preset position range is further distinguished by shading. Because the scaling instrument has tooth position specificity and tooth surface specificity, different working ends 21 are suitable for different tooth surfaces and positions on different teeth. Figure 4 The shaded area in the diagram represents the treatment area corresponding to one of the working ends of the curette. Figure 4 The non-shaded surface in the diagram represents the treatment area corresponding to the other working end of the curette.
[0058] For example, if the subgingival curette 20 of model #5-6 is already in the corresponding first preset usage area—anterior tooth region A, then the second preset usage area of the corresponding working end 21 is further obtained through the working end judgment component. For example, the second preset usage area of the working end 21 is the shaded area within the first preset position range. When the relative distance between the second micro-sensor 22 corresponding to the subgingival curette 20 of model 5 and the first micro-sensors 13 corresponding to Y1, Y2, Y3, and Y4 is within the preset distance, it is determined that the usage area of the working end 21 of the current subgingival curette 20 is within the second preset usage area of the working end 21; otherwise, it is not.
[0059] The depth determination component obtains the preset depth range of the corresponding tooth model 12 based on the received first tag information, and determines whether the relative position of the working end 21 of the subgingival curette 20 and the bottom of the periodontal pocket is within the preset depth range.
[0060] The target treatment area is the root surface between the gingival margin and the alveolar bone margin around the tooth model 12, and the signal of the first microsensor 13 in each tooth model 12 contains the preset depth range of the corresponding tooth model 12.
[0061] In the above embodiment, it is necessary to first use the model determination component to determine whether the working end 21 of the current subgingival curette 20 is within the corresponding first preset working area, and then use the working end determination component to further determine whether the working end 21 of the current subgingival curette 20 is within the corresponding second preset working area.
[0062] An angle determination unit, connected to the receiving unit, determines the angle of the subgingival curette 20 by calculating the relative angle between the first micro sensor 13 and the second micro sensor 22, and determines whether the angle of the subgingival curette 20 exceeds the preset angle range.
[0063] The force judgment unit is connected to the receiving unit. It acquires the measurement data of the pressure sensor 23 based on the signal of the pressure sensor 23, determines the force of the subgingival curette 20 based on the measurement data of the pressure sensor 23, and judges whether the measurement data of the pressure sensor 23 exceeds the predetermined value.
[0064] In the above embodiments, through the calculation and judgment of the processing module 30, the user can know the correct area, correct depth, correct angle and correct force of the periodontal subgingival curette 20, and thus complete the training correctly.
[0065] In a preferred embodiment, the processing module 30 further includes: a virtual model construction unit, which creates a virtual tooth model for each tooth model 12, the virtual tooth model being mapped to the first tag of the first micro-sensor 13 inside the tooth model 12, and creates a virtual oral cavity model without the virtual tooth model installed, obtains the corresponding virtual tooth model based on all received first tag information, and installs the virtual tooth model onto the periodontal pocket position corresponding to the virtual oral cavity model.
[0066] The intelligent periodontal subgingival scaling training device also includes: a display module 40, connected to the processing module 30, for real-time display of the model of the subgingival scaling tool 20, the measurement data of the pressure sensor 23, the relative position of the working end 21 of the subgingival scaling tool 20 to the bottom of the periodontal pocket calculated by the processing module 30, and the angle of the subgingival scaling tool 20.
[0067] In a preferred embodiment, the virtual model building unit includes:
[0068] The virtual tooth model creation component scans the tooth model 12 and creates a virtual tooth model corresponding to the tooth model 12, and establishes a mapping relationship between the virtual tooth model and the first micro-sensor 13 inside the virtual tooth model; through this mapping relationship, the processing module 30 can obtain the corresponding virtual tooth model by acquiring the signal from the first micro-sensor 13.
[0069] The virtual oral cavity model creation component scans the main body of the dental oral cavity model and the gingival model 11, and creates the corresponding virtual dental oral cavity model;
[0070] Assemble the components, receive signals emitted by all the first microsensors 13, obtain the corresponding virtual tooth model according to the first tag in the signal, and place the virtual tooth model on the corresponding periodontal pocket position according to the relative position between the first microsensors 13.
[0071] It should be noted that a three-dimensional tooth model 12 with tooth model 12 positioning can be obtained through the virtual model construction unit. The three-dimensional tooth model 12 can be displayed on the screen. Subsequently, the entire operation process can be displayed more intuitively on the screen by combining with the three-dimensional calculation unit.
[0072] In the above embodiments, by monitoring the relative position, angle of use, and force of the probe in real time, the trainee can immediately understand whether their operation is accurate, thereby adjusting their technique in a timely manner and avoiding problems caused by misjudgment in actual operation.
[0073] During operation, the working end 21 of the subgingival curette 20 needs to be inserted into the periodontal pocket of the gingival model 11. The processing module 30 will calculate the relative position of the working end 21 of the corresponding model of subgingival curette 20 to the bottom of the periodontal pocket, the angle of the subgingival curette 20, and the measurement data of the pressure sensor 23. Based on the relative position of the working end 21 of the subgingival curette 20 to the bottom of the periodontal pocket, it will determine whether the current use position of the subgingival curette 20 is within the correct use area and provide real-time feedback to the display module 40, so as to help the operator find the right feel.
[0074] In a preferred embodiment, a cache module is also included, connected to the processing module 30, for storing the model of the subgingival curette 20, as well as the historical relative position of the working end 21 of the corresponding model of the subgingival curette 20 to the periodontal pocket floor and the historical angle of the subgingival curette 20.
[0075] In a preferred embodiment, the processing module 30 further includes a three-dimensional calculation unit, which is used to calculate the corresponding three-dimensional coordinate change value of the working end 21 of the subgingival curette 20 based on the historical relative position of the working end 21 of the subgingival curette 20 and the periodontal pocket floor.
[0076] In a preferred embodiment, the 3D calculation unit sends the stored data to the display module 40, which then displays the 3D coordinate changes using a line graph. This 3D digital recording of the curettage operation process, displayed in real-time via a visual interface, visualizes the movement trajectory of the subgingival curettage device 20, facilitating observation and analysis of the trainee's performance by both the trainer and instructor.
[0077] In a preferred embodiment, a speaker is also included, connected to the processing module 30, for issuing prompts.
[0078] In a preferred embodiment, the processing module 30 includes a prompting unit;
