Description

Technical Field

Background Art

In modern dental treatment, dental implant surgery has become a common treatment method. However, the traditional dental implant design and analysis process usually relies on manual operation by medical personnel, which has many limitations. First, manual operation is easily affected by the technical level and subjective factors of medical operators, resulting in instability and errors in the design results. Secondly, the image data collected during the operation may be missing or incomplete, resulting in the inability to fully reflect the three-dimensional structure inside the mouth, limiting the accurate assessment of the implant position and morphology. In addition, the traditional data collection method is time-consuming and cumbersome, which is not conducive to the rapid promotion of clinical applications.

By consulting the relevant disclosed technologies, the technical solution with publication number EP3113712A1 proposes a medical robotic arm, which determines the patient's dental implant position and the tooth status related to the dental implant through an automated detection procedure; the technical solution with publication number CN112309560A proposes a remote dental implant operation that can be performed by a local mechanical operating device in cooperation with the operation of remote medical personnel; the technical solution with publication number AU2016396405A1 proposes a dental implant abutment suitable for intraoral scanning equipment, which can accurately position the dental implant abutment during oral scanning through special design of the abutment.

The technical solutions proposed in the above technical solutions all involve technical means to improve the accuracy of dental implants or reduce the difficulty of operation.

More specifically, returning to FIG. 3 , in an exemplary embodiment, the scanning unit may perform scanning using a technique and device based on triangulation, confocal scanning, focal scanning, X-ray scanning, stereoscopic vision, optical coherence tomography (OCT) or other scanning;

Preferably, the scanning unit forms a series of two-dimensional image stacks by projecting a scanning light 16 on the optical axis 15 and capturing multiple two-dimensional images at different focal plane positions while moving the focal plane along the optical axis 15; preferably, the computing unit 20 processes these two-dimensional image stacks to generate processed data, from which depth information can be inferred, and the data is processed to form three-dimensional data; or, three-dimensional data can be generated based on the two-dimensional image stack or the processed data; optionally, the scanning unit is a focus scanning device, which obtains multiple two-dimensional images by moving the focal plane of the light projected by the light source 11; in a preferred embodiment, the movement of the focal plane is achieved by an adjustable focal length lens; multiple lenses in the lens move back and forth during operation to change the focal plane in a predefined distance; the focal plane position preferably moves along the optical axis 15 of the scanning light projected by the light source 11, so that the focal plane is changed along the optical axis 15. The two-dimensional images captured at multiple focal plane positions of the optical axis 15 can form the two-dimensional image stack, or sub-scan set; and multiple sub-scan sets are formed for given views of multiple orientations/viewing angles of the target object; after moving the scanning unit relative to the target object to scan and collect at different views, a new two-dimensional image stack under the view can be captured; the scanning unit can make at least some sub-scan sets at least partially overlap by moving and adjusting the angle during the scanning operation, so as to be stitched in post-processing; after stitching, a digital three-dimensional surface representation larger than the field of view that can be captured by a single sub-scan set will be obtained; stitching, also known as registration, is achieved by identifying the overlapping areas of the three-dimensional surface in each sub-scan set and converting the sub-scan sets into a common coordinate system to match the overlapping areas, and finally generating a digital three-dimensional representation; preferably, an iterative closest point (ICP) algorithm can be used to achieve the above matching work;

In other embodiments, a triangulation scanning technique may be used to project various time-varying light rays onto the tooth surface, and one or more image sensors located at the same viewing angle relative to the light source may be used to acquire image sequences configured in different modes;

In an exemplary embodiment, one or more light sources 11 may be configured, and the light source 11 may be configured to emit light of a single wavelength or a combination of multiple wavelengths; optionally, the light source includes a main light source for emitting a main scanning light 16; in a preferred embodiment, the light emitted by the main light source is unpolarized; the main light source may be configured to emit white light, i.e., light with a wavelength of about 380 nm to 750 nm; optionally, the main light source may be a white light emitting diode (LED), which may be a phosphor LED or an indium gallium nitride (InGaN) LED;

Optionally, the main light source is a laser generator, which can be configured to emit light of a single wavelength or a narrow wavelength spectrum; for example, the main light source can be configured to emit light in the range from 625nm to 850nm; light of more than two wavelength combinations or ranges can be generated by using a light source configured to generate light including different wavelengths; or, the light source can include a plurality of LEDs that individually generate different wavelengths (such as red, green and blue), which can be combined to form light including different wavelengths;

Optionally, the light source 11 may include a secondary light source configured to emit light of a second wavelength or wavelength range; the light emitted by the secondary light source may also be non-polarized; in a preferred embodiment, the second wavelength is configured to excite fluorescent materials in the subject's oral cavity to obtain fluorescence data of multiple parts of the oral cavity including the target object; for example, the second wavelength may be configured to excite bacteria in the oral cavity so that the bacteria emit fluorescence higher than the second wavelength; the second wavelength may be selected from the range of 380nm to 485nm, or a narrower range such as 400nm to 435nm, or a narrower range such as 405nm to 425nm; in a preferred example, the scanning device includes a secondary light source configured to emit light of approximately 405nm wavelength; the secondary light source may emit light having a spectrum with a narrow wavelength band near a spectral peak; for example, the secondary light source may emit light having a wavelength range from approximately 400nm to approximately 435nm, wherein the peak of the spectrum is located at approximately 405nm; in some examples, the secondary light source is configured to emit light with an emission maximum (peak) within a sub-range of the wavelength range emitted by the primary light source;

In addition, the light source 11 may include one or more additional light sources, such as an infrared (IR) light source or a near infrared (NIR) light source, wherein the light from the IR/NIR light source is capable of penetrating tooth tissue; infrared light may be understood as light having a wavelength selected from the range of 700 nm to 1 mm; near infrared light may be understood as light having a wavelength selected from the range of 750 nm to 1.4 μm;

In an exemplary embodiment, the light source 11 can be a digital light processing (DLP) projector that uses a micromirror array to generate a time-varying pattern, or a diffractive optical element (DOE), or a front-illuminated reflective mask projector, or a micro-light projector; an LED projector, or a liquid crystal on silicon (LCoS) projector, or a backlit mask projector, wherein the light source is placed behind a mask having a spatial pattern, whereby the light projected onto the surface of the dental object is patterned; the pattern can be dynamic, i.e., the pattern changes over time, or the pattern can be static, i.e., the pattern remains the same over time; the light projector can include a collimating lens for collimating the light from the light source, the collimating lens being placed between the light source and the mask; the positional features of the scanned object can be more easily identified by the patterned scanning light 16;

In a preferred embodiment, the correction mechanism is used to adjust the position and/or angle of the reflective lens in the reflection mechanism (13) to ensure that the optical path of the scanning light 16 remains correct when the scanning front end rotates; the correction mechanism can be implemented in the following ways:

Piezoelectric actuators use the tiny size and precise control characteristics of piezoelectric materials to achieve extremely fine angle adjustment. Piezoelectric actuators can generate enough force to adjust the angle of the reflective lens in a very small space. The piezoelectric element is small in size and has a fast response speed, which is very suitable for high-precision and fast-response application scenarios.

Micro stepper motors have the advantages of precise positioning and simple control. Using micro stepper motors can effectively save space while maintaining good angle control capabilities. Through precise drive circuits, micro-stepping operations can be achieved to further improve positioning accuracy. They are suitable for scanning front ends with narrow operating spaces and high-precision requirements.

Flexible Mechanical Linkage: Design a small flexible mechanical linkage system to change the angle of the reflector by fine-tuning the length or shape of the linkage; this design uses the elastic properties of the material to achieve fine-tuning, which can effectively adapt to compact design requirements while ensuring accurate adjustment of the reflection angle;

Magnetic actuation mechanism: Use magnetic materials and small electromagnets to create a contactless actuation mechanism; the electromagnet can precisely control the strength and direction of the magnetic force, and adjust the position and angle of the reflective lens by changing the magnetic force; this design not only saves space, but also reduces wear and maintenance requirements due to the lack of physical contact;

Micro motor and gear combination: Use small motors with precision gears to achieve a compact drive system; by optimizing the gear ratio and gear design, sufficient torque and precise angle adjustment can be provided in a limited space;

In an exemplary embodiment, in order to enable the imaging unit 12 to be placed in the internal space of the main body 21, the imaging platform of the imaging unit 12 is set to an angle parallel to the optical axis 15, and the reflected light 17 returned from the outside is further changed through the reflective component after the light path is changed, and then the reflected light 17 is projected onto the imaging surface of the imaging unit 12.

Embodiment 2: This embodiment should be understood to include at least all the features of any of the above embodiments, and further improve upon them;

In an exemplary embodiment, the control instruction determines the value β of the angle interval by the following calculation method, so that when the scanning front end rotates to reach the target angle β _end , it stops and performs a sampling on the way every time it rotates through one angle interval β as image data redundancy;

In the above formula, Q is the current scan image quality evaluated by the operation unit; v is the rotation speed of the scanning front end, k is the speed adjustment coefficient; f() is a function of the rated pixel density D of the imaging unit 13 and the currently scanned angle θ; C is the angle adjustment coefficient, and the values of k and C can be initially set according to the scanning proficiency of the operator; wherein,

f(D,θ)＝exp(-α·D-bθ);

In the above formula, exp() is an exponential operation of natural logarithm; as the rated pixel density D increases or the angle deviation θ increases, the function value of f(D,θ) will decrease, which means that β will increase, that is, when the image quality is good or the scanning condition is stable, the scanning end 22 does not need to stop scanning frequently; a and b are pixel density adjustment coefficients and subdivision adjustment coefficients, which are optimized by relevant designers after scanning experiments on the scanning capability of the scanning unit;

Preferably, the scan quality Q can use a machine learning-based model to comprehensively evaluate multiple quality factors in the image data, including pixel density, scan resolution, scan coverage and depth, brightness consistency, and noise level; an exemplary step of determining Q includes:

(1) Feature extraction: First, feature extraction is performed on the image data obtained from each scan; these features include: pixel density: the number of pixels per unit area in the image;

Scanning resolution: the level of detail of objects in an image, usually expressed in dots per inch (DPI);

Scan coverage and depth: the size of the spatial area and the depth range covered by the scan;

Brightness consistency: the uniformity of brightness distribution in an image;

Noise level: the degree of random interference in the image;

(2) Feature standardization: In order to make the feature values suitable for processing by machine learning models, the features need to be standardized, such as scaling to the [0, 1] interval or performing z-score standardization;

(3) Training a machine learning model: Using a labeled training dataset that contains the above features and corresponding image quality labels (such as "high", "medium", and "low" quality), train a classification model; this model can be a support vector machine (SVM), random forest, or deep neural network;

(4) Quality assessment: The extracted features are input into the trained model to obtain the quality assessment result Q of each scanned image; the model will output a continuous quality score, which reflects the overall quality of the image data;

(5) Real-time feedback application: The Q value can be calculated in real time and used to adjust scanning parameters or as a decision support, such as deciding whether to rescan a specific scanning area or adjust the scanning path.
