[0047] Implant evaluation aims to evaluate the performance, safety, and biocompatibility of the implant to be evaluated to ensure that the implant can stably support the prosthesis for a long time without causing adverse effects on the surrounding tissues. Currently, in the related art, the artifacts formed by metal implants can lead to missed or misjudged lesions, making it impossible to accurately evaluate the bone mass and density around the implant during the clinical treatment process, interfering with the judgment of the tooth movement direction and the relationship between the tooth root and the implant, resulting in a low level of automation in the implant evaluation process and poor accuracy of the implant evaluation results.

[0048] In view of this, in the first aspect of the embodiments of the present application, a method for evaluating an oral implant material is proposed. Figure 1A flowchart of an oral implant material evaluation method 100 provided by an embodiment of the present application is shown as follows. Figure 1 As shown, method 100 includes:

[0049] Step S110: Obtain target information, where the target information includes: first attribute information and second attribute information. The first attribute information belongs to the implant to be evaluated, and the second attribute information belongs to the target implant tissue.

[0050] Exemplarily, the above first attribute information may include: material attribute information and dimension attribute information of the implant to be evaluated. It should be noted that the above first attribute information may also include: the shape, cross-sectional area, and / or implantation position of the implant to be evaluated, etc.

[0051] Exemplarily, the above material attribute information may include: atomic number, and / or density parameter, etc.

[0052] Specifically, when the material corresponding to the implant to be evaluated includes materials such as titanium alloy and cobalt-chromium alloy, the material attribute information corresponding to the implant to be evaluated may include: the atomic number corresponding to titanium alloy, and / or density parameter, etc., and the atomic number corresponding to cobalt-chromium alloy, and / or density parameter, etc.

[0053] Exemplarily, the above dimension attribute information may include: the length, diameter, volume, etc. of the implant to be evaluated. Specifically, the above length may include: the total length of the implant to be evaluated, and / or the length of the part of the implant to be evaluated implanted in the alveolar bone. The above diameter may correspond to the maximum width of the implant to be evaluated.

[0054] In some feasible embodiments, the above second attribute information includes: attribute information of the target implant tissue.

[0055] Exemplarily, the above target implant tissue may include: target alveolar bone tissue, target soft tissue, etc. The attribute information of the above target implant tissue may include: material attribute information and dimension attribute information of the target implant tissue.

[0056] Exemplarily, the above material attribute information of the target implant tissue may include: the atomic number corresponding to the target implant tissue, and / or density parameter, etc.

[0057] Exemplarily, the above dimension attribute information of the target implant tissue may include: the volume of the target implant tissue, the height of the target implant tissue, and / or the thickness of the target implant tissue, etc.

[0058] It should be noted that the above first attribute information and the above second attribute information can be determined by manual input.

[0059] Step S120: Generate a first target model and a second target model according to the target information.

[0060] Exemplarily, a first target model including the implant to be evaluated and the target implant tissue can be generated according to the above first attribute information.

[0061] Exemplarily, a second target model including only the target implant tissue but not the implant to be evaluated can be generated according to the above second attribute information.

[0062] Among them, the above first target model and second target model can be generated based on MCNP software.

[0063] Based on this, by accurately generating the first target model and the second target model according to the attribute information of the implant to be evaluated and the attribute information of the target implant tissue, the simulation accuracy of the physical structure of the implant to be evaluated and the target implant tissue can be improved, and the simulation accuracy of the matching relationship and / or the structural association relationship between the implant to be evaluated and the target implant tissue can be improved, and the experimental cost and risk caused by physical entity experiments can be reduced.

[0064] Step S130: Generate a target artifact analysis result according to the first target model and the second target model.

[0065] In some feasible embodiments, generating a target artifact analysis result according to the first target model and the second target model includes: applying a target γ photon beam to the first target model to obtain first signal distribution information; applying a target γ photon beam to the second target model to obtain second signal distribution information; generating a target artifact analysis result according to the first signal distribution information and the second signal distribution information.

[0066] Exemplarily, by setting the energy parameter, intensity parameter, incident angle parameter, detector resolution parameter, collimator parameter, and / or detector detection efficiency parameter of the X-ray, that is, the target γ photon beam, it can be simulated to apply the X-ray, that is, the target γ photon beam, to the first target model to obtain first signal distribution information, and it can be simulated to apply the X-ray, that is, the target γ photon beam, to the second target model to obtain second signal distribution information. Among them, the parameters of the X-ray, that is, the target γ photon beam, applied to the first target model are the same as those of the X-ray, that is, the target γ photon beam, applied to the second target model. Among them, the above parameters include: the energy parameter, intensity parameter, incident angle parameter, detector resolution parameter, collimator parameter, and / or detector detection efficiency and other parameters of the X-ray source, that is, the target γ photon beam.

[0067] Based on this, by applying the target γ photon beam to the first target model and the second target model, it is beneficial to accurately simulate the physical interaction process between the target γ photon beam and the implant to be evaluated, so as to obtain the first signal distribution information, and accurately simulate the physical interaction process between the target γ photon beam and the target implant tissue, so as to obtain the second signal distribution information. Thus, by comparing the first signal distribution information and the second signal distribution information, the target artifact analysis result can be accurately generated, providing accurate data support for accurately generating the material evaluation result of the implant to be evaluated according to the target artifact analysis result.

[0068] In some feasible embodiments, the generating of the target artifact analysis result according to the first signal distribution information and the second signal distribution information includes: determining the intensity attenuation information and / or scattering information of the target γ photon beam according to the first signal distribution information and the second signal distribution information; generating the target artifact analysis result according to the intensity attenuation information and / or scattering information.

[0069] Exemplarily, the above first signal distribution information and second signal distribution information can be determined based on the corresponding CBCT images.

[0070] It should be noted that after the target γ photon beam passes through the first target model or the second target model, the target γ photons will interact with the implant to be evaluated or the target implant tissue, causing the energy of the target γ photon beam to be lost, thereby causing the signal distribution to change. Among them, the above interactions can include: photoelectric effect, Compton scattering, and / or pair production effect, etc. The above signal distribution changes can include: intensity change and / or propagation direction change.

[0071] It should be noted that when the atomic number of the material corresponding to the implant to be evaluated is relatively high and the density is relatively large, the target γ photon beam will have a strong photoelectric effect with the implant to be evaluated. A large number of inner shell electrons of the metal atoms corresponding to the implant to be evaluated will undergo transitions, causing a large number of γ photons in the target γ photon beam to be absorbed. The number of γ photons at the position corresponding to the implant to be evaluated will be significantly reduced, resulting in a strong attenuation of the intensity of the target γ photon beam. Then, the degree of signal change at the position corresponding to the implant to be evaluated is relatively high, and bright white stripes will be formed at the position corresponding to the implant to be evaluated, masking the structure of the target implant tissue. Among them, the above structures may include fine structures such as tiny blood vessels and periodontal membranes. Conversely, when the atomic number of the material corresponding to the implant to be evaluated is relatively small and the density is relatively small, the target γ photon beam will have a weak photoelectric effect with the implant to be evaluated. A small number of inner shell electrons of the metal atoms corresponding to the implant to be evaluated will undergo transitions, causing a small number of γ photons in the target γ photon beam to be absorbed. The number of γ photons at the position corresponding to the implant to be evaluated will be slightly reduced, resulting in a weak attenuation of the intensity of the target γ photon beam. Then, the degree of signal change at the position corresponding to the implant to be evaluated is relatively small, and the contrast with the target implant tissue is relatively small. Dark stripes or blurred images will be formed at the position corresponding to the implant to be evaluated.

[0072] In some feasible embodiments, determining the intensity attenuation information and / or scattering information of the target γ photon beam based on the first signal distribution information and the second signal distribution information includes: determining the intensity attenuation information according to the following formula:

[0073] I = I 0 ×e -μx (1)

[0074] where I is the intensity of γ photons penetrating through a thickness of x, I 0 is the initial intensity of γ photons, μ is the linear attenuation coefficient, x is the penetration thickness, and e is the base of the natural logarithm.

[0075] It should be noted that the above linear attenuation coefficient μ is positively correlated with the atomic number Z, density ρ of the implant to be evaluated, and the energy E of γ photons. That is, the larger the atomic number Z, density ρ of the implant to be evaluated, and the higher the energy E of γ photons, the larger the linear attenuation coefficient μ, and the faster the intensity attenuation of γ photons.

[0076] It should be noted that due to the relatively low atomic number of the target implant tissue, the target γ photon beam will have a strong Compton scattering with the implant to be evaluated, which will cause a large change in the direction of the target γ photon beam and result in a loss of some energy.

[0077] Exemplarily, the above scattering information may include scattering angle information and / or scattering cross-section information.

[0078] In some feasible embodiments, determining the intensity attenuation information and / or scattering information of the target γ photon beam based on the first signal distribution information and the second signal distribution information further includes: determining the scattering information according to the following formula:

[0079]

[0080] where λ is the wavelength of the γ photon before scattering, λ′ is the wavelength of the γ photon after scattering, m e is the electron rest mass, c is the speed of light, and θ is the scattering angle.

[0081] It should be noted that the scattering cross-section σ c is positively correlated with the atomic number Z. The above scattering cross-section σ c is negatively correlated with the energy E of the γ photon within a preset range.

[0082] It should be noted that in some feasible embodiments, the determination accuracy of the above first signal distribution information and the second signal distribution information can be improved by adjusting the energy, intensity, and / or incident angle of the γ photon, so as to improve the determination accuracy of the target artifact analysis result.

[0083] Thus, the above method can accurately determine the intensity attenuation information and / or scattering information according to the above formulas (1)-(2).

[0084] Based on this, by comparing the first signal distribution information and the second signal distribution information, the above method can accurately determine the intensity attenuation information and / or scattering information of the target γ photon beam passing through the implant to be evaluated and / or the target implant tissue, so as to accurately generate the target artifact analysis result, providing data support for objectively quantifying and evaluating the performance of the implant to be evaluated.

[0085] Step S140; generating a material evaluation result of the implant to be evaluated according to the target artifact analysis result.

[0086] In some feasible embodiments, the above target artifact analysis result includes: the gray-scale distribution information, shape information, and / or area information of the target artifact.

[0087] Exemplarily, the gray-scale distribution information, shape information, and / or area information of the target artifact can be determined by comparing the first signal distribution information and the second signal distribution information.

[0088] It should be noted that before determining the gray-scale distribution information, shape information, and / or area information of the target artifact based on the above-mentioned first signal distribution information and second signal distribution information, a filtering operation can be performed on the first signal distribution information and the second signal distribution information to achieve precise noise reduction of the first signal distribution information and the second signal distribution information. Specifically, the target filtering parameters can be set based on methods such as Gaussian filtering to perform the filtering operation on the first signal distribution information and the second signal distribution information.

[0089] Specifically, by comparing the gray-scale histograms of the first signal distribution information and the second signal distribution information, the difference between the gray-scale histogram corresponding to the first signal distribution information and the gray-scale histogram corresponding to the second signal distribution information can be determined, and based on the above difference, the gray-scale distribution information of the target artifact can be determined.

[0090] Specifically, based on an edge detection algorithm, according to the above-mentioned first signal distribution information and second signal distribution information, the boundary of the target artifact can be determined to determine the above-mentioned shape information.

[0091] It should be noted that in the case where the structure and shape of the implant to be evaluated are relatively complex, the shape of the artifact corresponding to the implant to be evaluated will be distorted and bent, and the masking range of the artifact on the target implant tissue is relatively large, which will affect the observation of the target implant tissue. Among them, the above-mentioned target implant tissue includes: teeth around the implant position corresponding to the implant to be evaluated, and / or alveolar bone, etc. In the case where the structure and shape of the implant to be evaluated are relatively regular, the shape of the artifact corresponding to the implant to be evaluated is relatively regular, and the masking range of the artifact on the target implant tissue is relatively small, and it appears concentrated at the position corresponding to the implant to be evaluated, showing a concentric ring distribution or a radial distribution.

[0092] In some feasible embodiments, the above method further includes: determining the boundary of the target artifact according to the gray-scale distribution information; performing a target operation on the boundary to determine the target boundary; and determining the above area information according to the target boundary.

[0093] Exemplarily, the boundary of the target artifact can be determined based on a target gray-scale threshold, where the above-mentioned target gray-scale threshold can be 200.

[0094] Specifically, in the case where it is determined according to the gray-scale histogram that the gray-scale value of the corresponding point is greater than 200, then the above-mentioned point is determined as the target point, and based on multiple above-mentioned target points, the boundary of the target artifact is determined.

[0095] It should be noted that the above-mentioned target operation can include: an erosion operation, and / or a dilation operation.

[0096] Exemplarily, an erosion operation can be performed on the above-mentioned boundary to eliminate isolated points and / or irregular line segments composed of multiple points in the above-mentioned boundary, and then a dilation operation is performed to compensate for the eliminated isolated points and / or irregular line segments, thereby determining the above-mentioned target boundary.

[0097] Specifically, the above-mentioned erosion operation and / or dilation operation can be performed based on a target structuring element. Among them, the above-mentioned target structuring element can be set by itself according to the actual situation. For example: the above-mentioned target structuring element can be a structuring element with a size of 3×3.

[0098] Exemplarily, the above-mentioned area information can be determined according to the number of pixels included in the above-mentioned target boundary and the size of a single pixel. Among them, the artifact area is the product of the number of pixels included in the target boundary and the area of a single pixel.

[0099] Thus, the above method can accurately determine the boundary of the target artifact according to the gray-scale distribution information, perform a target operation on the above boundary to determine the target boundary, and accurately determine the area information according to the above target boundary.

[0100] Alternatively, the above-mentioned area information can also be determined based on a region of interest (ROI) set by the target user himself.

[0101] Exemplarily, the target user can select a corresponding shape selection tool according to the shape information of the above-mentioned target artifact to determine the above-mentioned area information. Among them, the above-mentioned corresponding shape selection tool can include: a rectangular selection tool, a circular selection tool, and / or an irregular shape selection tool.

[0102] Specifically, when the shape of the target artifact is circular, the above-mentioned region of interest can be selected based on the circular selection tool to determine the above-mentioned area information.

[0103] In some feasible embodiments, after the above-mentioned selection operation is completed, the scale information of the target artifact can be determined based on a preset calibration tool.

[0104] Exemplarily, the above-mentioned scale information can be determined based on a preset calibration tool according to a reference object with a known standard size.

[0105] Specifically, based on a preset calibration tool, the size value of a single pixel can be determined according to a metal sphere with a known diameter of 5 mm. According to the number of pixels included in the above-mentioned region of interest and the size value of the above-mentioned single pixel, the above-mentioned area information is determined.

[0106] Thus, the above method can generate a material evaluation result of the implant to be evaluated in multiple dimensions according to the gray-scale distribution information, shape information, and / or area information of the target artifact, thereby improving the generation accuracy of the material evaluation result of the implant to be evaluated.

[0107] In some feasible embodiments, the above method further includes: determining the coverage rate information of the target artifact on the key points according to the coverage position information of the target artifact on the target implant tissue; generating an evaluation result according to the coverage rate information.

[0108] Exemplarily, the above key points can be determined according to the anatomical information and / or atlas information of the target implant tissue. Specifically, the above key points may include: nerve canals, vascular bundles, adjacent tooth roots, maxillary sinus floor, and / or bone margins, etc.

[0109] Exemplarily, the above coverage rate can be determined as the ratio of the number of pixels of the key points covered by the above target artifact to the total number of pixels of the key points.

[0110] Specifically, the above coverage rate can be determined according to the following formula:

[0111]

[0112] In some feasible embodiments, weights can be set for multiple key points to generate the above evaluation result according to the weights of each key point and the coverage rate of each key point.

[0113] Specifically, when the total coverage rate of the above target artifact on multiple above key points is greater than the preset total coverage rate threshold, and / or when the coverage rate of the above target artifact on a single above key point is greater than the corresponding coverage rate threshold, the above evaluation result is output as unqualified.

[0114] Specifically, when the total coverage rate of the above target artifact on multiple above key points is less than or equal to the preset total coverage rate threshold, and moreover, when the coverage rate of the above target artifact on a single above key point is less than or equal to the corresponding coverage rate threshold, the above evaluation result is output as qualified.

[0115] Among them, the above total coverage rate can be determined according to the following formula:

[0116]

[0117] Among them, the above n is the number of key points, the coverage rate i is the coverage rate of the i-th key point, and the weight i is the weight of the i-th key point.

[0118] Based on this, the above method can accurately determine the coverage rate information of the target artifact on the key points according to the coverage position information of the target artifact on the target implant tissue, and generate the above evaluation result accurately and objectively according to the above coverage rate information.

[0119] It should be noted that when the total coverage rate of the target artifact on multiple key points is greater than the preset total coverage rate threshold, and / or when the coverage rate of the target artifact on a single key point is greater than the corresponding coverage rate threshold, that is, when the above evaluation result is unqualified, the component ratio of the implant to be evaluated can be adjusted so that the total coverage rate of the target artifact on multiple key points is less than or equal to the preset total coverage rate threshold, and the coverage rate of the target artifact on a single key point is less than or equal to the corresponding coverage rate threshold, that is, the evaluation result is qualified, so as to realize the automatic adjustment of the component ratio of the implant to be evaluated, avoid the omission or misjudgment of lesions caused by the artifact formed by the metal implant, and enable accurate evaluation of the bone mass and density around the implant during the clinical treatment process, reduce the interference in the judgment of the tooth movement direction and the relationship between the tooth root and the implant, thus providing convenience for clinical treatment.

[0120] Based on this, the method for evaluating oral implant materials provided in this application includes: obtaining target information, where the target information includes: first attribute information and second attribute information, where the first attribute information belongs to the implant to be evaluated, and the second attribute information belongs to the target implant tissue; generating a first target model and a second target model according to the target information; generating a target artifact analysis result according to the first target model and the second target model; generating a material evaluation result of the implant to be evaluated according to the target artifact analysis result. This application is conducive to accurately simulating the physical structure of the implant to be evaluated, the target implant tissue, and the cooperation relationship, and / or the structural association relationship between the implant to be evaluated and the target implant tissue according to the first attribute information and the second attribute information. According to the physical structure of the implant to be evaluated, the target implant tissue, and the cooperation relationship, and / or the structural association relationship between the implant to be evaluated and the target implant tissue, the target artifact analysis result can be accurately determined while saving experimental costs, and the material evaluation result of the implant to be evaluated can be accurately output according to the target artifact analysis result, thereby improving the automation level of the implant evaluation process and the accuracy of the implant evaluation result.

[0121] It should be noted that for the foregoing method embodiments, for the sake of simple description, they are all expressed as a series of action combinations. However, those skilled in the art should know that this application is not limited by the described action sequence, because according to this application, certain steps can be performed in other sequences or simultaneously.
