Description

Technical Field

[0001] This application relates to the field of intelligent medicine, and specifically to a method, device, program product, and computer-readable storage medium for screening donor teeth for autologous tooth transplantation. Background Art

[0002] The research on autologous tooth transplantation stems from the reflection on the limitations of traditional tooth loss restoration methods (such as dental implants and removable dentures). Although these methods are widely used, they have problems such as high cost, risk of foreign body rejection, and accelerated bone resorption, especially limited effects on teenagers or patients with insufficient bone mass. Autologous tooth transplantation, by transplanting the patient's own teeth (such as the third molar) into the tooth defect area and utilizing the biocompatibility of natural teeth and the regeneration potential of the periodontal membrane, has become an alternative solution with both functional restoration and biological advantages. In recent years, the innovation of imaging technologies (such as CBCT and dynamic 3D modeling) has significantly improved the matching accuracy between donor teeth and recipient areas. Combined with artificial intelligence (AI)-aided planning, it can analyze the root morphology, alveolar bone conditions, and bite force distribution in real time. For example, the AI algorithm launched in 2024 can already predict the pulp survival rate after transplantation through multi-modal data, reducing the risk of postoperative necrosis. In the process of autologous tooth transplantation, the screening of donor teeth needs to consider the adaptability of donor teeth. The root length and curvature of donor teeth need to match the alveolar socket of the recipient area, and it is necessary to ensure the survival of periodontal cells in donor teeth after extraction (time-sensitive, usually <30 minutes), otherwise it will lead to postoperative healing risks (such as pulp necrosis) and functional restoration risks (such as occlusion).

[0024] Figure 1 Schematic diagram of the donor tooth screening method for autologous tooth transplantation provided by an embodiment of the present invention, specifically including: S101: Obtain the dental image of the patient; In one embodiment, the dental image includes a CBCT image.

[0025] S102: Obtain the root form, tooth integrity, and impaction position of the tooth based on the dental image; In one embodiment, the root form includes a fused root, a bifurcated root, and a trifurcated root; the tooth integrity includes fully erupted, partially erupted, and completely impacted; the impaction position includes vertical impaction, mesial impaction, distal impaction, buccal impaction, lingual impaction, and inverted impaction.

[0026] S103: After the first screening based on the root morphology, root donor teeth are obtained; In one embodiment, the first screening process is as follows: when the root morphology of the patient's tooth includes fused roots and bifurcated roots, select the tooth with fused roots as the donor tooth; when the root morphology of the patient's tooth includes fused roots and trifurcated roots, select the tooth with fused roots as the donor tooth; when the root morphology of the patient's tooth includes bifurcated roots and trifurcated roots, select the tooth with bifurcated roots as the donor tooth; when the root morphology of the patient's tooth includes fused roots, bifurcated roots, and trifurcated roots, select the tooth with fused roots as the donor tooth; after screening, root donor teeth are obtained.

[0027] S104: Based on the tooth integrity, the root donor teeth are subjected to a second screening to obtain integrity donor teeth; In one embodiment, the second screening process is as follows: when the tooth integrity of the patient's tooth includes fully erupted and partially erupted, select the fully erupted tooth as the donor tooth; when the tooth integrity of the patient's tooth includes fully erupted and completely impacted, select the fully erupted tooth as the donor tooth; when the tooth integrity of the patient's tooth includes partially erupted and completely impacted, select the partially erupted tooth as the donor tooth; when the tooth integrity of the patient's tooth includes fully erupted, partially erupted, and completely impacted, select the fully erupted tooth as the donor tooth; after screening, integrity donor teeth are obtained.

[0028] S105: Through the impacted position, the integrity donor teeth are subjected to a third screening to obtain donor teeth.

[0029] In one embodiment, the third screening process is to screen for donor teeth with vertical impaction taking precedence over mesial impaction, distal impaction taking precedence over buccal impaction, and lingual impaction taking precedence over inverted impaction.

[0030] In one embodiment, the method further includes a fourth screening, and the donor teeth are subjected to a fourth screening through the tooth position to obtain donor teeth.

[0031] In one embodiment, the tooth position includes ipsilateral, contralateral, same jaw, and opposite jaw.

[0032] In one embodiment, the fourth screening process is to screen for donor teeth with ipsilateral taking precedence over contralateral and same jaw taking precedence over opposite jaw. The donor teeth at this time are the donor teeth obtained through the tooth position screening.

[0033] In one embodiment, the method further includes a fifth screening, and the donor teeth are screened through the function of the teeth; the functions of the teeth include caries-free, carious, no apical region, apical region, no periodontal inflammation, and periodontal inflammation.

[0034] In one embodiment, the fifth screening process selects donor teeth with non-carious teeth taking precedence over carious teeth, apical regions taking precedence over non-apical regions, and non-periodontal inflammation taking precedence over periodontal inflammation. The donor teeth at this time are donor teeth after tooth function screening.

[0035] In one embodiment, after the third screening, the fourth screening is carried out first and then the fifth screening to obtain donor teeth; or after the third screening, the fifth screening is carried out first and then the fourth screening to obtain donor teeth.

[0036] In one embodiment, the tooth images are screened in sequence by root morphology, tooth integrity, impaction position, tooth position, and tooth function to obtain donor teeth.

[0037] In one embodiment, the priorities for donor tooth screening include: 1. fused root > bifurcated root > trifurcated root; 2. fully erupted > partially erupted > completely impacted; 3. vertical impaction > mesio-distal impaction > bucco-lingual impaction > inverted impaction; The midface is the midline, and the tooth is regarded as a cube. The side closer to the midline is the mesial surface, and the side away from the midline is the distal surface. The surface close to the cheek is the buccal surface, and the surface close to the tongue is the lingual surface (for lower teeth) or the palatal surface (for upper teeth).

[0038] 4. ipsilateral > contralateral, same jaw > opposite jaw; 5. Those without caries, apical regions, and inflammation of the periodontal tissue are preferentially considered.

[0039] In one embodiment, the method further includes autologous tooth transplantation planning. After three-dimensional reconstruction and registration of the N selected donor teeth and the recipient tooth, the final donor tooth is obtained, where N is a natural number greater than or equal to 1. Virtual transplantation of the final donor tooth is performed to obtain the transplantation angle and direction, and the transplantation angle and direction are the planned angle and direction.

[0040] In one embodiment, after the third screening is carried out through the impaction position to obtain donor teeth, the width and depth of the donor teeth at this time are calculated. When the width and depth of the donor teeth match the alveolar socket of the recipient tooth, it is determined as a candidate donor tooth; when the width and depth of the donor teeth do not match the alveolar socket of the recipient tooth, a donor tooth with integrity is obtained, and the width and depth of the donor tooth with integrity are calculated. When the width and depth of the donor teeth match the alveolar socket of the recipient tooth, it is determined as a candidate donor tooth; when the width and depth of the donor teeth do not match the alveolar socket of the recipient tooth, a donor tooth with roots is obtained, and the width and depth of the donor tooth with roots are calculated to obtain a suitable donor tooth as a candidate donor tooth.

[0041] When the depth of the donor tooth is 2 - 3 mm smaller than the alveolar socket and the width is 1 - 2 mm smaller than the alveolar socket, it is determined as a match.

[0042] In one embodiment, the donor teeth are screened by one or more of the root morphology, tooth integrity, impaction position, tooth position, and tooth function screening indicators. The multi-round screening is carried out based on the previous round (or independently screened based on different screening indicators, and the intersection of the donor teeth obtained by independent screening is taken to obtain the donor teeth). After obtaining the donor teeth, the width and depth are calculated, and the matching degree with the alveolar socket depth and width of the recipient tooth is calculated. When the matching degree is met, the donor tooth is a candidate donor tooth. When the matching degree is not met, one screening indicator is reduced to obtain the donor teeth and the matching degree is calculated and compared. This step is repeated until a suitable candidate donor tooth is obtained or the number of donor teeth is zero.

[0043] In one embodiment, the process of surgical planning for donor teeth includes: Obtaining the dental image of the patient; Segmenting the dental image to obtain single-tooth images, including the recipient tooth and N donor teeth, where N is a natural number greater than 1; Performing three-dimensional reconstruction based on the single-tooth images to obtain three-dimensional single teeth; Calculating the morphology of the three-dimensional recipient tooth and the three-dimensional donor teeth and performing registration to obtain the registered recipient tooth; Adjusting the angle and direction of the registered recipient tooth through virtual transplantation to obtain the planned angle and direction.

[0044] The registration is to perform rigid registration and angle adjustment on the morphology of the three-dimensional recipient tooth and the donor teeth through morphological calculation, and the registered recipient tooth is screened out.

[0045] The process of the rigid registration and angle adjustment includes tooth center point positioning, tooth long axis positioning, and dental arch positioning. After sequentially determining the tooth center, tooth long axis, and dental arch, the three-dimensional recipient tooth and the three-dimensional donor teeth are registered. The tooth center point positioning is to define a global coordinate system, and in the global coordinate system, the translation matrix for moving the center point of the three-dimensional donor tooth to the center point of the three-dimensional recipient tooth is calculated to obtain the tooth center point positioning result.

[0046] Optionally, the tooth long axis positioning is: performing eigen decomposition on the matrix based on the tooth center positioning to obtain eigenvectors, screening the eigenvectors to obtain the eigenvector corresponding to the maximum eigenvalue as the tooth long axis vector, including the tooth long axis vector of the three-dimensional donor tooth and the tooth long axis vector of the three-dimensional recipient tooth; Adjusting the direction of the tooth long axis vector, and the tooth long axis vector points from the tooth root to the tooth crown; Taking the tooth center point as the rotation center, calculating the rotation matrix for transforming the tooth long axis vector of the three-dimensional donor tooth to the tooth long axis vector of the three-dimensional recipient tooth to obtain the tooth long axis positioning result.

[0047] Optionally, the dental arch positioning fits the dental arch curve according to the dental center points, including the dental arch curve of the three-dimensional donor tooth and the dental arch curve of the three-dimensional recipient tooth. The initial direction of the three-dimensional donor tooth is calculated through morphology, and the initial direction of the three-dimensional recipient tooth is calculated based on the dental arch tangent direction. Taking the dental long axis of the recipient tooth as the rotation axis, the rotation matrix from the initial direction of the three-dimensional donor tooth to the initial direction of the three-dimensional recipient tooth is calculated to obtain the dental arch positioning result.

[0048] The adjustment of the angle and direction of the planned path includes the establishment of the occlusal plane, the establishment of the axial inclination, and the establishment of the torsion. The upper and lower positions of the recipient tooth are determined through the occlusal plane, the left and right positions are determined through the axial inclination and torque, and the connection of the teeth is determined through the torsion.

[0049] The establishment of the occlusal plane is determined by the centroid and dental long axis of the three-dimensional donor tooth. First, the centroid of the three-dimensional donor tooth is calculated to obtain the centroid coordinates, then the dental long axis of the three-dimensional donor tooth is calculated, and based on the centroid coordinates and the dental long axis, the occlusogingival position of the donor tooth in three-dimensional space is obtained, and the occlusal plane is established by adjusting the occlusogingival position. The axial inclination is changed by rotating 5° along the buccolingual direction mesially or distally, and the axial inclinations at different rotation angles are compared to screen out the axial inclination. The establishment of the axial inclination also includes the establishment of the root movement angle, and the root movement direction is precisely controlled by rotating 5° along the mesiodistal direction buccally or lingually. The establishment of the torsion is to first create a cross quadrant. In each quadrant, the three-dimensional donor tooth is rotated 45° - 75° along the dental long axis N times, where N is a natural number greater than 1, and the selected quadrant is screened out; in the selected quadrant, the three-dimensional donor tooth is rotated 5° - 10° counterclockwise or clockwise to obtain the rotation angle, and the rotation angles are compared to screen out the torsion.

[0050] In a specific embodiment, in the functional architecture of the final plan visualization, it includes two parts: quantitative indicators and result visualization. The quantitative indicators provide clinical doctors with plan data analysis in the form of a TXT file. The result visualization needs to convert the format through the MITK image processing software and present the autologous tooth virtual transplantation plan through 3-matics.

[0051] The surgical operations of both the experimental group and the blank control group were completed by a single dentist. The difference was that in the experimental group, an assistant was also required to convert the surgical plan into a three-dimensional stereoscopic image (STL), perform the calculate part operation on all the masks of the automatically segmented CBCT in Mimics research 21.0, export 3D objects to 3-matics, copy the surgical plan in STL mode to 3-matics to synchronously visualize the transplantation effect, provide more intuitive and accurate surgical guidance for the surgeon, and record the main intraoperative evaluation indicators - the ex vivo time of the donor tooth and the number of trial implantations.

[0052] In a specific embodiment, after obtaining the plan based on the preoperative planning, staged tooth extraction is performed, and implant instruments and donor tooth fixation methods are recommended according to the difficulty of tooth extraction.

[0053] In a specific embodiment, for Case 1, the patient had Tooth 37 to be extracted, with a poor original occlusion relationship, shallow overbite and shallow overjet of the anterior teeth. There was an edge-to-edge occlusion relationship of the left posterior teeth, and Tooth 38 had no normal occlusion relationship with the opposing teeth. Teeth 37 and 38 were significantly inclined mesially. Therefore, it was considered to extract Tooth 37 and replace it with Tooth 38 in this patient to attempt to restore the normal occlusal function. This patient also had the most common problem of insufficient alveolar bone mass clinically. Therefore, the patient's venous blood was drawn into a specific test tube before the operation of this case and immediately placed in a centrifuge for balancing and centrifugation. CGF was made due to the different inner walls of the test tubes and the centrifugation speed. After being pressure-formed, the CGF was used as a barrier membrane. Subsequently, an implant surgery was performed through preoperative planning. It could be seen from the immediate postoperative CBCT that due to the severe chronic periapical periodontitis of the recipient tooth Tooth 37 in the recipient alveolar socket, there was a large area of low-density images in the apical region, as shown in Figure 4. However, at 1 year after the operation, obvious new bone formation was found around the tooth root, and the transplanted tooth showed a gradually recovering trend.

[0054] In another embodiment, for Case 2, as Figure 5As shown in the figure, tooth 26 of the patient needs to be extracted, and there are three donor teeth 18 / 38 / 48 in the mouth at the same time. The AI surgical planning reference platform gives the visual results of the above transplantation plan. The reference platform also gives virtual transplantation to two teeth. The best surgical plan given by the reference platform is to transplant tooth 38 to tooth 26. The visual results show that the alveolar socket preparation work mainly focuses on the palatal and mesial regions of the alveolar socket, and the bone grinding volume is 6160 voxels. In terms of data, compared with the previous case, the bone grinding volume of this case is larger. Therefore, the side cutting drill or ball drill of the high-speed handpiece can no longer meet the bone grinding volume. Therefore, in this case, an implant handpiece is used for the preparation of the alveolar socket. After extracting tooth 26, the implant machine is equipped with a corresponding trephine bur, and the cavity is prepared in the mesial and palatal regions of the alveolar socket at a rotational speed of 1000 r / min, and at the same time, it is cooled with 0.9% sodium chloride solution at 4°C. After reaching the predetermined depth, the preparation of the alveolar socket is completed. The alveolar cavity is repeatedly rinsed with 0.9% sodium chloride solution to thoroughly remove the bone chips and granulation tissue in the alveolar cavity. Subsequently, the donor tooth is extracted by the minimally invasive extraction method and implanted into the alveolar socket according to the virtual transplantation direction of the surgical planning reference platform. Then, it is sutured with silk thread suspension, and the transplanted tooth is fixed to the adjacent teeth by using stainless steel wire, periodontal fiber fixation band and light-cured resin. Finally, the necessary occlusal adjustment is carried out on the donor tooth to ensure no occlusal interference, and the autologous tooth transplantation surgery of case two is completed. At 6 months after the operation, the loosening degree of the transplanted tooth is 0. When reexamined 1 year after the operation, the tooth is stable, the loosening degree returns to normal, the periodontal health is good, the pulp vitality test is vital, and there is no sinus tract in the gingiva. The percussion sound is normal, there is no sign of attachment loss, no periodontal pocket, no sign of inflammation, no discomfort, and the chewing function has recovered. The prognosis of this case is very rapid in all cases. First of all, the original occlusal relationship of the patient's dentition is normal, without smoking habits and periodontal diseases, and the teeth are cleaned regularly every six months. The patient has very good compliance. The imaging changes in the reexamination film half a year after the operation can be seen as Figure 6 As shown, the low-density image around the apex of the transplanted tooth shows a gradually shrinking trend, without signs of progressive root resorption. There is still a sparse area in the mesial apical region, but there is a manifestation of bone healing around the apical sparse area.
