[0063] In the present invention, the so-called "first" and "second" do not represent specific quantities and orders, but are only used for name distinction.

[0064] As Figure 1 shown, a method for positioning bone graft in oral implant bone augmentation surgery in an embodiment of the present invention includes the following steps:

[0065] S1. Establish rules for sharing oral implant bone data, obtain multiple oral hospital servers, network the multiple oral hospital servers, and build a data sharing network for oral implant bone graft.

[0066] For the rules for sharing oral implant bone data, it can be understood as several sharing limitations such as the range of types of oral implant bone data participating in sharing, the region and age range of corresponding patients (i.e., identity characteristics), the degree of newness and oldness, and the levels of corresponding oral hospitals. That is to say, by establishing rules for sharing oral implant bone data, its function is to define the scope of oral implant bone data participating in sharing, facilitate the screening of oral hospital servers, obtain multiple qualified oral hospital servers and network the multiple oral hospital servers to build a data sharing network for oral implant bone graft.

[0067] S2. Obtain a target oral bone graft patient and the target oral hospital of the target oral bone graft patient, and based on the target oral hospital, obtain the weight coefficients of other oral hospitals in the data sharing network for oral implant bone graft except the target oral hospital.

[0068] Preferably, in step S2, as Figure 2 shown, the specific method for obtaining the weight coefficients of other oral hospitals in the data sharing network for oral implant bone graft except the target oral hospital based on the target oral hospital includes the following steps:

[0069] S21. Obtain the multi-dimensional first characteristic data values of each other stomatological hospital and the first characteristic data standard values corresponding to each of the first characteristic data values.

[0070] For the first characteristic data values, it includes but is not limited to the hospital grade, scoring ranking, daily active user numbers on the web and / or mobile terminals, registered user numbers, daily outpatient reception volume, annual outpatient reception volume, and hospital APP download volume of the stomatological hospital. For the first characteristic data standard values, they can be set by technicians.

[0071] S22. Obtain the first weight factor of each other stomatological hospital according to the multi-dimensional first characteristic data values of each other stomatological hospital and the first characteristic data standard values corresponding to each of the first characteristic data values.

[0072] Specifically, the first weight factor can be understood as the weighted average of the first weight scores of the multi-dimensional first characteristic data values relative to the corresponding first characteristic data standard values; where n represents the total number of dimensions of the multi-dimensional first characteristic data values, e represents the natural constant, cdv 1i represents the first characteristic data value of the i-th dimension of a certain other stomatological hospital, cdv1'i represents the first characteristic data standard value corresponding to the first characteristic data value of the i-th dimension of a certain other stomatological hospital, α i represents the proportional adjustment coefficient of the first characteristic data value of the i-th dimension of a certain other stomatological hospital, which can be set by technicians. According to the formula it can be known that if the first characteristic data value of a certain dimension is equal to the first characteristic data standard value, that is, the first weight score corresponding to the first characteristic data value of this dimension is zero. If the first characteristic data value of a certain dimension is less than the first characteristic data standard value, its first weight score is negative. For the first characteristic data value of a certain dimension, the greater the difference between it and the corresponding first characteristic data standard value, the greater the absolute value of the corresponding first weight score. Therefore, based on the formula to a certain extent, by combining the multi-dimensional first characteristic data values of the stomatological hospital, the comprehensive first weight score, that is, the first weight factor, can clearly reflect the overall situation of each other stomatological hospital, such as authority, popularity, and patient satisfaction. Indirectly, according to the first weight factor, the effectiveness and accuracy of the bone grafting information of the oral bone grafting patients in its server can also be reflected.

[0073] S23. Obtain the multi-dimensional first feature data values of the target oral hospital, and calculate the second weight factor of each other oral hospital according to the multi-dimensional first feature data values of the target oral hospital and the multi-dimensional first feature data values of each other oral hospital.

[0074] Specifically, the second weight factor where u i represents an intermediate variable, and cdv1”i represents the first feature data value of the i-th dimension of the target oral hospital. One of the functions of the second weight factor is to perform targeted screening according to the magnitude relationship between the first feature data value of the target oral hospital and the first feature data values of other oral hospitals. The weighted average of the second weight scores obtained from the first feature data values of other oral hospitals that are larger than the first feature data value of the target oral hospital after screening (i.e., the second weight factor) can better reflect the medical service quality and technical level of other oral hospitals relative to the target oral hospital. Indirectly, according to the second weight factor, it can also reflect the effectiveness and reference significance of the bone grafting information of oral bone grafting patients in other oral hospital servers relative to the target oral bone grafting patient.

[0075] S24. Obtain the weight coefficients of other oral hospitals in the oral implant bone graft data sharing network except the target oral hospital according to the first weight factor and the second weight factor.

[0076] The weight coefficient SEWC = (β1×WeightFactors1 + β2×WeightFactors1) / 2; where β1 and β2 respectively represent the first weight factor adjustment coefficient and the second weight factor adjustment coefficient, both of which can be set by technicians.

[0077] S3. For the target oral bone grafting patient, obtain the oral medical image of the target oral bone grafting patient, and obtain the bone defect area feature information according to the oral medical image.

[0078] The oral medical image includes but is not limited to oral CT images and oral CBCT images. The bone defect area feature information includes but is not limited to the location, size, and contour line of the bone defect area.

[0079] S4. Obtain the bone grafting information of all oral bone grafting patients including the target oral bone grafting patient in the oral implant bone graft data sharing network, and calculate the correlation degree between the bone grafting information of the target oral bone grafting patient and the bone grafting information of other oral bone grafting patients respectively.

[0080] Preferably, in step S4, as Figure 3As shown in the figure, the specific method for calculating the correlation degree between the bone grafting information of the target oral bone grafting patient and the bone grafting information of other oral bone grafting patients includes the following steps:

[0081] S41. Respectively obtain the identity characteristic information of the target oral bone grafting patient and the other oral bone grafting patients. According to the identity characteristic information, calculate the correlation coefficient between the target oral bone grafting patient and each of the other oral bone grafting patients.

[0082] Specifically, the identity characteristic information is multi-dimensional identity characteristic values. The identity characteristic values include, but are not limited to, age, gender, weight, and BMI body fat percentage.

[0083] The correlation coefficient is obtained by calculating the weighted average of the ratio values of the identity characteristic values of each dimension between the target oral bone grafting patient and the other oral bone grafting patients. Among them, m represents the total number of dimensions of the multi-dimensional identity characteristic values, e represents the natural constant, ccv 1i represents the identity characteristic value of the i-th dimension of the target oral bone grafting patient, ccv1'i represents the same as the identity characteristic value of the i-th dimension of the target other oral bone grafting patient, and δ i represents the ratio adjustment coefficient of the identity characteristic value of the i-th dimension of the target oral bone grafting patient, which can be set by the technician.

[0084] S42. Calculate the correlation degree according to the correlation coefficient. The correlation degree R = Correlation + C; where C represents the correlation degree correction value, which is set by the technician according to the target oral bone grafting patient to improve the accuracy of the correlation degree.

[0085] By calculating the correlation degree between the bone grafting information of the target oral bone grafting patient and the bone grafting information of other oral bone grafting patients respectively, according to the correlation degree, the reference value of the bone grafting information of other oral bone grafting patients relative to the bone grafting information of the target oral bone grafting patient can be obtained more clearly and intuitively. Generally speaking, the greater the correlation degree, the greater the reference value of the corresponding bone grafting information of other oral bone grafting patients for the target oral patient.

[0086] S5. Obtain the bone grafting positioning information according to the weight coefficient, the bone defect area characteristic information, and the correlation degree, and process the autologous block bone according to the bone grafting positioning information to realize the bone grafting positioning of the oral implant bone augmentation surgery.

[0087] Preferably, as Figure 4 shown, in step S5, the specific method for obtaining the bone grafting positioning information according to the weight coefficient, the bone defect area characteristic information, and the correlation degree includes the following steps:

[0088] S51. Obtain the first bone defect area contour line according to the bone defect area characteristic information.

[0089] S52. Obtain the bone defect area contour line correction value according to the weight coefficient and the correlation degree.

[0090] Specifically, first set a weight coefficient threshold and a correlation degree threshold, screen the bone grafting information of other oral bone grafting patients in other oral hospital servers with a weight coefficient greater than the weight coefficient threshold, obtain the bone grafting information of other oral bone grafting patients with a correlation degree greater than the correlation degree threshold and record it as the preferred bone grafting information. Among them, the contour line correction value of the bone defect area characteristic information is included in the preferred bone grafting information; then, according to the contour line correction value of the bone defect area characteristic information in the preferred bone grafting information, the corresponding weight coefficient and the correlation degree, by calculating the mean value of the weighted average of the weight coefficient and the contour line correction value and the weighted average of the correlation degree and the contour line correction value, obtain the bone defect area contour line correction value.

[0091] S53. Obtain the second bone defect area contour line according to the first bone defect area contour line and the bone defect area contour line correction value.

[0092] Taking the bone defect area contour line correction value as a reference, magnify the first bone defect area contour line to obtain the second bone defect area contour line. For example, if the bone defect area contour line correction value is M millimeters, the second bone defect area contour line can be obtained by magnifying the entire first bone defect area contour line by M millimeters.

[0093] S54. Obtain bone surface data according to the first bone defect area contour line and the second bone defect area contour line, and obtain bone augmentation guiding design data according to the bone surface data.

[0094] Specifically, intercept the bone surface data between the first bone defect area contour line and the second bone defect area contour line, use the curvature continuous skinning algorithm to construct the outer surface after bone augmentation in the area that needs bone augmentation, thicken the outer surface after regional bone grafting and reserve a bone grafting material filling hole in the central area to obtain bone augmentation guiding design data.

[0095] Preferably, as Figure 5 shown, the specific method for obtaining bone grafting positioning information according to the weight coefficient, the bone defect area characteristic information and the correlation degree further includes the following steps:

[0096] S55. Obtain the optimal autogenous block bone oral implant data according to the first bone defect area contour line.

[0097] The autologous block bone oral implant data can be understood as the size of the autologous block bone. For the optimal autologous block bone oral implant data, it can be obtained by acquiring the largest regular polyhedron inscribed within the contour line of the first bone defect region.

[0098] S56. Obtain the optimal autologous block bone grinding allowance according to the weight coefficient and the degree of association.

[0099] Specifically, first set a weight coefficient threshold and a degree of association threshold, screen the bone transplantation information of other oral bone transplantation patients in other oral hospital servers with a weight coefficient greater than the weight coefficient threshold, obtain the bone transplantation information of other oral bone transplantation patients with a degree of association greater than the degree of association threshold and record it as the preferred bone transplantation information. Among them, the preferred bone transplantation information also includes the autologous block bone grinding allowance; then according to the autologous block bone grinding allowance in the preferred bone transplantation information, the corresponding weight coefficient, and the degree of association, by calculating the mean value of the weighted average of the weight coefficient and the autologous block bone grinding allowance and the weighted average of the degree of association and the autologous block bone grinding allowance, obtain the optimal autologous block bone grinding allowance.

[0100] S57. Obtain the optimal autologous block bone cutting data according to the optimal autologous block bone oral implant data and the optimal autologous block bone grinding allowance. It can be understood that the optimal autologous block bone cutting data is obtained by superimposing the optimal autologous block bone oral implant data and the optimal autologous block bone grinding allowance. One method is to acquire the largest regular polyhedron inscribed within the contour line of the first bone defect region and supplement the optimal autologous block bone grinding allowance on the outer surface of the largest regular polyhedron to obtain the optimal autologous block bone cutting data.

[0101] S58. Obtain the autologous block bone according to the optimal autologous block bone cutting data, grind the autologous block bone according to the optimal autologous block bone oral implant data, and perform transplantation positioning on the ground autologous block bone according to the bone defect region.

[0102] That is, cut the autologous block bone with the corresponding size according to the optimal autologous block bone cutting data, grind the autologous block bone according to the optimal autologous block bone oral implant data, such as referring to the largest regular polyhedron inscribed within the contour line of the first bone defect region, and finally perform transplantation positioning on the ground autologous block bone according to the bone defect region.

[0103] By combining the weight coefficient and the correlation degree, the bone grafting information of other oral hospital servers and other oral bone grafting patients is screened, and the bone grafting information of other oral bone grafting patients with reference value is selected to obtain the optimal autologous block bone oral implant data and the optimal autologous block bone grinding allowance, which is beneficial to accurately obtain the autologous block bone, avoid the problems of excessive cutting or insufficient cutting, and at the same time, based on the optimal autologous block bone grinding allowance, the grinding of the obtained autologous block bone can also be accelerated, improving the overall implant efficiency of the autologous block bone.

[0104] In summary, the bone grafting positioning method for oral implant bone augmentation surgery obtains the weight coefficient, the bone defect area feature information and the correlation degree, and obtains the bone grafting positioning information according to the weight coefficient, the bone defect area feature information and the correlation degree to process the autologous block bone. It comprehensively considers multiple different dimensions of bone grafting data information, can optimize the autologous block bone processing technology, and improves the positioning accuracy and intelligence level of oral implant bone grafting.
