[0042] The concept, specific structure and resulting technical effects of the present application will be described clearly and completely in combination with embodiments and drawings below, so as to fully understand the purpose, features and effects of the present application.
[0043] Embodiment 1 A comprehensive oral diagnosis and treatment system, as shown in Figure 1 and Figure 2 , comprises: a tooth movement monitoring module based on low-radiation or non-radiation ultrasonic imaging technology, which monitors the tooth movement trajectory in orthodontic treatment in real time, including direction, speed and force condition, and captures the anchorage control and reaction force distribution of the tooth; a low-intensity pulsed ultrasound module based on low-intensity pulsed ultrasound technology, which promotes periodontal tissue repair in orthodontic treatment through non-invasive mechanical vibration; a high-intensity focused ultrasound module based on high-intensity focused ultrasound technology, which performs functional regulation and treatment of the temporomandibular joint and surrounding muscles; a blood flow monitoring module based on ultrasonic Doppler technology, which monitors the blood flow changes on the pressure side and tension side of the tooth and evaluates the biomechanical response in the orthodontic process; a control module, a wireless communication module, a terminal module and a cloud server, the tooth movement monitoring module, the low-intensity pulsed ultrasound module, the high-intensity focused ultrasound module and the blood flow monitoring module are all in communication connection with the control module, and the control module and the terminal module are both in communication connection with the cloud server through the wireless communication module.
[0044] Embodiment 2 This embodiment is further described on the basis of the tooth movement monitoring module of the above-mentioned embodiment: Core function: the device uses low-radiation or non-radiation ultrasonic imaging technology to monitor the tooth movement trajectory in orthodontic treatment in real time, including direction, speed and force condition. Combined with intelligent algorithm, precise evaluation of anchorage control and reaction force distribution is realized.
[0045] Technical implementation: Ultrasound imaging module: integrated miniaturized B-mode or A-mode ultrasound imaging system, real-time capture of dynamic changes in tooth movement.
[0046] Data storage and analysis: use AI algorithms to analyze historical and real-time data to generate a three-dimensional trajectory graph of tooth movement, while providing biomechanical force line analysis.
[0047] Application scenarios: suitable for precise monitoring of complex orthodontic cases (such as patients with high anchorage requirements or significant tooth reaction forces).
[0048] In this invention, the tooth movement monitoring module uses low-radiation or non-radiation ultrasound imaging technology to monitor the trajectory of tooth movement in orthodontic treatment in real time, including direction, speed and force, and capture the anchorage control and reaction force distribution of teeth.
[0049] The purpose of monitoring the direction of tooth movement is to real-time grasp the actual displacement vector of each tooth in three-dimensional space, and timely find abnormal directions such as non-planned tilting, rotation or sliding out of the bracket, so as to avoid the re-production of the appliance or the extension of the treatment course due to direction deviation.
[0050] The purpose of monitoring the speed of tooth movement is to quantify the rate of tooth movement and verify whether the current force is in the "optimal biological response interval" (0.2-0.3 mm / week), to prevent root resorption caused by too fast or prolonged treatment course caused by too slow.
[0051] The purpose of monitoring the force condition of tooth movement is to quantify the force / torque size received by each tooth, to ensure the "light force correction" principle (50-150 g orthodontic force, 50-100 g·mm torque), and to reduce the risk of root resorption and periodontal necrosis.
[0052] The purpose of capturing the anchorage control of teeth is to real-time evaluate whether the anchorage teeth appear unexpected displacement, to ensure that the maximum anchorage design (such as micro-implant anchorage) is always effective, and to avoid "anchorage loss" leading to treatment failure.
[0053] The purpose of capturing the reaction force distribution of teeth is to draw the full-arch reaction force field and analyze whether the "action-reaction" is balanced, to provide quantitative basis for the doctor to redesign the mechanical system (such as replacing NiTi wire, adding compensation curve).
[0054] In this invention, the specific implementation scheme of monitoring the direction of tooth movement is: The ultrasound imaging submodule continuously collects B-mode slices at a frame rate of ≥30fps; The AI edge detection algorithm (U-Net++) labels the tooth crown and root tip at the sub-pixel level; Through the multi-frame correlation algorithm based on Kalman filtering, the instantaneous displacement Δx, Δy, Δz of the dental centroid in the x-y-z direction is calculated, so as to obtain the direction cosine (cosα, cosβ, cosγ); When the included angle θ between the direction cosine and the preset orthodontic path is greater than 5°, the control module immediately pushes a warning to the doctor's end APP.
[0055] The specific implementation scheme for monitoring the tooth movement speed is: According to the above direction calculation result, Δx, Δy, Δz are differentiated with respect to time to obtain the instantaneous velocity vector v; In the cloud server, a personalized biological response model (LSTM network) is established, the speed v and the patient's bone density parameters are input, and the "recommended force value" is output; The control module automatically adjusts the LIPUS output intensity or reminds the doctor to replace the arch wire / patient to replace the dental cover according to the recommended value.
[0056] The specific implementation scheme for monitoring the tooth stress condition is: A Micro-Electro-Mechanical Systems (MEMS, micro-electro-mechanical system) six-dimensional force sensor (range 0-500g, resolution 0.1g) is embedded in the personalized diaphragm; The sensor data and the ultrasonic image are synchronously sampled, and the force F and the moment M of each tooth are calculated through the inverse algorithm of rigid body dynamics; When |F|>150g or |M|>100g•mm, the LIPUS instantaneous pressure reduction mode is triggered, and a red alarm is pushed to the doctor's end.
[0057] The specific implementation scheme for capturing the anchorage control of the tooth is: The anchorage tooth (usually the first molar) is defined as ROI-anchor in advance; The digital image correlation (DIC) algorithm is used to track the surface microtexture and calculate the relative displacement; When the displacement of any anchorage tooth is greater than 0.1mm (threshold value can be adjusted), the system automatically increases the relaxation intensity of HIFU to the masticatory muscle, reduces the reaction force, and pushes the "anchorage loss risk" warning.
[0058] The specific implementation scheme for capturing the reaction force distribution of the tooth is: Through the finite element rapid inversion algorithm: taking the force F of each tooth as the boundary condition, the Von-Mises stress cloud of the entire dentition is reconstructed within 30ms; The stress cloud is superimposed on the three-dimensional dental model and displayed in the form of RGB heat map on the doctor's end APP; Doctors can interactively drag and drop "virtual attachments / brackets," and the system automatically updates the stress distribution and provides a "response force balance" score (0–100).
[0059] In this embodiment, two-dimensional sequence slice images acquired by the ultrasonic device are collected. ,in z i It is the first i The location of each slice ( i =1,2,…, N The goal is to reconstruct a continuous 3D image. .
[0060] Because the resolution of the x and y planes in a sequence of sliced images is higher than that of the z plane, direct 3D image stitching leads to image distortion. To correct this distortion, interpolation is needed in the z-direction. This method employs cubic spline interpolation.
[0061] Cubic spline interpolation uses piecewise cubic polynomials to fit data points, providing smoother reconstruction results. For any 3D image z, the 3D image... It can be calculated using the following formula:
[0062] in, For the first i 3D images of each slice location, For the first i A two-dimensional sequence of slice images with -1 slice location. For the first i Two-dimensional sequence slice images of slice locations, for i Two-dimensional sequence slice images with +1 slice positions, for i Two-dimensional sequence slice images with +2 slice positions, It is a cubic spline basis function, which depends on z Location; We can use interpolation methods to transform discrete two-dimensional slice data. Convert into a continuous 3D image The final 3D reconstruction formula can be expressed as:
[0063] in, To reconstruct the 3D image, For interpolation weight function, For the first i 3D images of each slice location.
[0064] Subsequently, the reconstructed three-dimensional image is smoothed and de-noised to obtain a final reconstruction result Subsequently, the reconstructed three-dimensional image is smoothed and de-noised to obtain a final reconstruction result .
[0065]
[0066] wherein, is the final three-dimensional image, is a Gaussian kernel function, denotes a convolution operation, is the reconstructed three-dimensional image.
[0067] Embodiment 3 This embodiment is based on the above-mentioned embodiments, and further describes the low-intensity pulsed ultrasound module: Core function: With the help of low-intensity pulsed ultrasound (LIPUS) technology, through non-invasive mechanical vibration, promote periodontal tissue repair in orthodontic treatment.

[0071] Clinical advantages: shorten the orthodontic treatment period, and at the same time reduce the possible tissue damage on the pressure side.
[0072] In the present application, the low-intensity pulsed ultrasound module utilizes low-intensity pulsed ultrasound technology to promote periodontal tissue repair in orthodontic treatment through non-invasive mechanical vibration. Among them, the non-invasive mechanical vibration refers to that under the premise of not piercing the mucosa and not damaging the bone cortex, through 1.5MHz±0.1MHz sound wave pulses, transient sound pressure (0.2-0.3MPa) and micro-displacement (≈50nm) are generated at the periodontal membrane-alveolar bone interface, thereby triggering cell-level biomechanical response. The specific implementation method is that the system first generates a 1.5MHz±0.1MHz, pulse repetition frequency 1kHz, duty cycle 20% drive signal by 8-bit single-chip microcomputer in cooperation with direct digital frequency synthesis chip; then amplified to 30mW / cm² safe dose through micro Class-D power amplifier.
