Description

Technical Field

[0001] This application relates to the field of data processing, and more particularly, to a complete denture tooth arrangement method and device. Background Art

[0002] With the increase in the aging population and the influence of eating habits, the number of edentulous patients is increasing. Due to characteristics such as low economic cost, fast cycle, and convenient adjustment, complete denture implantation is one of the feasible solutions for restoring the teeth of edentulous patients.

[0003] Currently, traditional complete denture tooth arrangement is based on a plaster model by a doctor, making a baseplate and recording the occlusion relationship on a wax rim. Then, a technician arranges the complete denture teeth and conducts aesthetic evaluation according to the anatomical marking points on the wax rim and the working model. This tooth arrangement method is based on the plaster model and the reference lines and reference planes marked by the doctor, so it highly depends on the experience and level of the technician. Moreover, after tooth arrangement, the doctor's reference lines and reference planes cannot be restored, so standardized inspection cannot be carried out, resulting in high cost and long time consumption.

DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0060] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0061] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0062] Traditionally, the doctor arranges the teeth for full dentures based on the plaster model, makes the base and records the occlusal relationship on the wax bank, and then the technician arranges the teeth for full dentures and makes an aesthetic assessment based on the anatomical landmarks of the wax bank and the working model. The specific operation is: after determining the appropriate upper and lower jaw position relationship, the teeth are arranged to determine the midline, canine position, maxillary tooth incisor position, tooth size, plane, etc.

[0063] The above traditional tooth arrangement method is separated from the reference of the face of the tooth arrangement object, and is completely based on the plaster model and the reference lines and reference planes marked by the doctor, which greatly depends on the experience and level of the technician, and the doctor's reference lines and reference planes cannot be restored after the tooth arrangement. Therefore, the doctor's reference lines and reference planes cannot be restored after the tooth arrangement, and standardized inspections cannot be performed. In addition, the cost of tooth arrangement is high and time-consuming.

[0064] In addition, the tooth arrangement scheme of the above-mentioned traditional tooth arrangement method often cannot satisfy the tooth arrangement object, and needs to be reworked, which increases the number of tooth arrangement times and costs.

[0065] Based on the above considerations, the embodiment of the present application provides a method for arranging teeth for a full denture, which provides a standardized way of arranging teeth based on the facial reference of the object to be arranged, optimizes the process of arranging teeth, makes the resulting arranging scheme more compatible with the object to be arranged teeth, and is simple to operate, which can reduce the cost and time of arranging teeth. Moreover, the arranging teeth does not need to rely on the experience and level of the technician, and can be standardized.

[0066] The full denture tooth arrangement method provided in the embodiment of the present application can be applied to Figure 1 In the full denture tooth arrangement system 1000 shown, the full denture tooth arrangement system 1000 may include a tooth arrangement device 10, a CBCT scanner 20 and a scanning device 30. The tooth arrangement device 10 may be connected to the CBCT scanner 20 and the scanning device 30 in a wired or wireless manner.

[0067] Before acquiring data, professionals can set fixed marker points on the face of the tooth arrangement object. For example, metal balls can be glued on the high points of the cheekbones and the nose tip on both sides of the tooth arrangement object as fixed facial marker points.

[0068] The scanning device 30 is used to scan the face of the tooth arrangement object in various facial states, superimpose the scan data in each facial state to obtain face scan data, and send the face scan data to the tooth arrangement device 10.

[0069] The CBCT scanner 20 is used to collect the upper and lower jaw mouth scan data of the tooth arrangement object, the oral CBCT data of the tooth arrangement object when the tooth arrangement object contains the bite recording silicone rubber, and the silicone rubber mouth scan data of the bite recording silicone rubber, and transmit the upper and lower jaw mouth scan data, the oral CBCT data and the silicone rubber mouth scan data to the tooth arrangement device 10.

[0070] The teeth arrangement device 10 is used to implement the full denture teeth arrangement method provided in the embodiment of the present application.

[0071] The scanning device 30 includes but is not limited to: a facial scanner and a CBCT scanner 20, etc. The tooth arrangement device 10 includes but is not limited to: an independent server, a server cluster, a personal computer, a laptop computer, and a tablet computer, etc.

[0072] In a possible embodiment, a method for arranging teeth of a complete denture is provided, referring to Figure 2 , may include the following steps. In this embodiment, the complete denture tooth arrangement method is applied to Figure 1 The tooth arrangement device 10 in FIG. 1 is used as an example.

[0073] S11, obtaining oral scan data of the upper and lower jaws of the tooth arrangement object, oral CBCT data of the bite recording silicone rubber in the mouth, and face scan data in various facial states, and obtaining silicone rubber oral scan data of the bite recording silicone rubber.

[0074] In this embodiment, the occlusal relationship of the tooth arrangement object is recorded on the occlusal recording silicone rubber, and after the professional determines the upper and lower jaw position relationship of the tooth arrangement object, the occlusal relationship of the tooth arrangement object is recorded with the silicone rubber to obtain the occlusal recording silicone rubber.

[0075] S13, aligning the upper and lower jaw mouth scan data and the silicone rubber mouth scan data, reconstructing and trimming the oral CBCT data to obtain pre-processed CBCT data, and superimposing and integrating the pre-processed CBCT data with the aligned upper and lower jaw mouth scan data and the silicone rubber mouth scan data to obtain first superimposed data.

[0076] S15, superimposing and integrating the first superimposed data and the face scan data to obtain second superimposed data.

[0077] S17, based on the second superposition data, perform tooth arrangement position and denture parameters to obtain a tooth arrangement plan.

[0078] After determining the upper and lower jaw position relationship of the tooth arrangement object, the professional records the occlusal relationship of the tooth arrangement object on the silicone rubber to obtain the occlusal record silicone rubber. In addition, the professional sets a fixed mark point on the face of the tooth arrangement object. The preset facial position for setting the fixed mark point can be arbitrarily selected, for example, it can be the nose wing or the corner of the mouth, which is not specifically limited in this embodiment.

[0079] In a possible implementation, the preset facial positions may be the highest points of the cheekbones on both sides and the tip of the nose, and professionals may bond metal balls to the highest points of the cheekbones on both sides and the tip of the nose of the patient to serve as fixed facial marking points. The radius of the metal balls may be flexibly set, for example, to 0.5 mm or 1 mm.

[0080] On the basis of the above, professionals can use the scanning device 30 to perform three-dimensional scanning on the face of the tooth arrangement object in various facial states to obtain face scanning data, and the scanning device 30 transmits the face scanning data to the tooth arrangement device 10. At the same time, professionals can use the CBCT scanner 20 to scan the upper and lower jaws of the tooth arrangement object to obtain upper and lower jaw mouth scanning data. And, the CBCT scanner 20 is used to scan the tooth arrangement object containing the bite record silicone rubber and the bite record silicone rubber respectively to obtain oral CBCT data and silicone rubber mouth scanning data of the bite record silicone rubber. The CBCT scanner 20 transmits the upper and lower jaw mouth scanning data, the oral CBCT data and the silicone rubber mouth scanning data to the tooth arrangement device 10.

[0081] It should be understood that the median position relationship between the upper and lower jaws of the tooth arrangement object can be obtained from the oral CBCT data.

[0082] The tooth arrangement device 10 receives face scan data, upper and lower jaw mouth scan data, oral CBCT data and silicone rubber mouth scan data, aligns the upper and lower jaw mouth scan data and the silicone rubber mouth scan data to obtain alignment data, and integrates the data for data complementation, so that the upper and lower jaw spatial position relationship of the tooth arrangement object described by the aligned data is more accurate. At the same time, the oral CBCT data is reconstructed and trimmed to eliminate interference data and correct fuzzy data to obtain pre-processed CBCT data. Then, the pre-processed CBCT data and the alignment data (i.e., the upper and lower jaw mouth scan data and the silicone rubber mouth scan data after cutting) are superimposed and integrated to obtain the first superimposed data.

[0083] After obtaining the first superimposed data, the tooth arrangement device 10 superimposes and integrates the first superimposed data with the face scan data to obtain the second superimposed data, so that the second superimposed data can not only record the facial state of the tooth arrangement object in various facial states, but also record more accurate upper and lower jaw spatial position relationship and upper and lower jaw middle position relationship, providing rich tooth arrangement information. Then, based on the second superimposed data, the tooth arrangement position points required for tooth arrangement are determined to obtain a tooth arrangement plan.

[0084] Compared with the traditional method of tooth arrangement, the above-mentioned full denture tooth arrangement method is simple to operate and can achieve standardized tooth arrangement without relying on the technician's wellbore and level, so that standardized inspection can be carried out after tooth arrangement, thereby improving the time-consuming problem of current tooth arrangement methods.

[0085] In addition, by recording the facial expressions of the tooth arrangement object in various facial states, the second superimposed data of more accurate upper and lower jaw spatial position relationship and the median position relationship of the upper and lower jaws are also recorded to perform tooth arrangement position and denture parameters, so that the tooth arrangement position determined based on the second superimposed data is more adapted to the tooth arrangement object, and the tooth arrangement process is optimized, which can improve the adaptability between the tooth arrangement plan and the tooth arrangement object, as well as customer satisfaction, thereby reducing the number of tooth arrangement times and reducing the cost of tooth arrangement.

[0086] For step S11, when acquiring face scan data, the selection of facial state can be flexibly set, for example, it can be laughing, smiling and expressionless, or smiling and expressionless. In this embodiment, no specific limitation is made.

[0087] In a possible implementation, in order to make the face scan data deeply related to the oral condition of the tooth arrangement object to improve the tooth arrangement effect, the facial state may include a natural resting state, a smiling state, a laughing state, and a state of containing the bite record silicone rubber in the mouth. At this time, the face scan data includes the first face scan data when the tooth arrangement object has a metal ball bonded to a preset position on the face and is in a natural resting state, the second face scan data when the tooth arrangement object has a metal ball bonded to a preset position on the face and is in a smiling state, the third face scan data when the tooth arrangement object has a metal ball bonded to a preset position on the face and is in a laughing state, and the fourth face scan data when the tooth arrangement object has a metal ball bonded to a preset position on the face and contains the bite record silicone rubber in the mouth.

[0088] It should be noted that the face scan data is the data obtained by superimposing the first face scan data, the second face scan data, the third face scan data and the fourth face scan data. When superimposing, the metal ball can be used as a reference point to find the same position point in the first face scan data, the second face scan data, the third face scan data and the fourth face scan data, perform position alignment, and superimpose the data of the same position point to obtain the face scan data.

[0089] When using a CBCT scanner to collect oral CBCT data and silicone rubber mouth scan data of the bite registration silicone rubber, in order to visualize the bite registration silicone rubber in the mouth of the tooth arrangement object and facilitate subsequent superposition and integration, a plurality of metal balls can be dispersedly set on the bite registration silicone rubber.

[0090] For example, the number of metal balls provided on the bite registration silicone rubber may be 6-18, and the diameter may be 1-3 mm. The same number of metal balls may be evenly placed on the labial and lingual sides and the left and right sides of the bite registration silicone rubber. Moreover, for each metal ball, half of the metal ball may be buried in the bite registration silicone rubber, and the other half of the metal ball may extend out of the surface of the bite registration silicone rubber.

[0091] With this arrangement, the bite registration silicone rubber can be visualized when collecting oral CBCT data and silicone rubber oral scan data.

[0092] For step S13, when aligning the upper and lower jaw mouth scan data with the silicone rubber mouth scan data, the first auxiliary tool can be called to select anatomical structure sites in the upper and lower jaw mouth scan data and the silicone rubber mouth scan data respectively, and align the upper and lower jaw mouth scan data with the silicone rubber mouth scan data based on the anatomical structure sites.

[0093] The first auxiliary tool may be three-dimensional drawing software such as Exocad software, which is not specifically limited in the present embodiment.

[0094] After importing the upper and lower jaw mouth scan data and the silicone rubber mouth scan data in STL format into the Exocad software, you can use the "Tools" → "Match Grid" → "Auto" function of the Exocad software to identify and select the same anatomical structure sites between the upper and lower jaw mouth scan data and the silicone rubber mouth scan data for alignment to complete the determination of the spatial position relationship between the upper and lower jaws.

[0095] The method for obtaining the pre-processed CBCT data may also be flexibly set. For example, the data may be reconstructed and trimmed according to preset rules or using auxiliary tools. In the present embodiment, no specific limitation is made.

[0096] In one possible implementation, refer to Figure 3 , oral CBCT data can be reconstructed and trimmed by the following steps.

[0097] S131, reconstructing the oral CBCT data using the reconstruction function of the second auxiliary tool.

[0098] S132, using the trimming function of the second auxiliary tool, trimming the reconstructed oral CBCT data to obtain pre-processed CBCT data.

[0099] The second auxiliary tool may be a medical imaging control system such as Materialise mimics, which is not specifically limited in this embodiment.

[0100] When the second auxiliary tool is Materialise mimics software, the oral CBCT data can be imported into the Materialise mimics software, the "segment" → "threshold" function can be called, and the threshold can be selected to reconstruct the oral CBCT data. Then, the "edit masks" function of the Materialise mimics software can be called in combination with manual trimming to eliminate interference data, correct erroneous data, etc., to obtain pre-processed CBCT data showing the upper and lower jaws, face, and metal balls on the bite registration silicone rubber.

[0101] Based on the above, since both the silicone rubber mouth scan data and the pre-processed CBCT data include metal ball data, refer to Figure 4 , obtaining the first superposition data in step S13 can be achieved through the following steps.

[0102] S133, based on the metal ball, determine the same position point of the pre-processed CBCT data and the aligned silicone rubber mouth scan data.

[0103] S135, based on the same position point, the jaw is used as the movement data, and the pre-processed CBCT data is correspondingly superimposed with the aligned upper and lower jaw mouth scan data and the silicone rubber mouth scan data to obtain the first superimposed data.

[0104] In actual scenarios, the pre-processed CBCT data in STL format can be imported into the Exocad software, and the "Tools" → "Match Grid" → "Automatic" function of the Exocad software can be called. The jaw is used as the moving data, and the data is superimposed and integrated by clicking the aligned silicone rubber mouth scan data and the same metal ball on the pre-processed CBCT data to obtain the first superimposed data.

[0105] Through the above steps S133 to S135, the superposition and integration of the jaw, bite record and upper and lower teeth (mucosa) are completed by data superposition, so that the first superposition data contains the positional relationship of the jaw, bite record and upper and lower teeth (mucosa).

[0106] For step S15, the method of superimposing and integrating the first overlapping data and the face scan data can also be flexibly selected. For example, the superimposition and integration can be performed according to preset rules, or a model can be used for superimposition and integration. In this embodiment, no specific limitation is made.

[0107] In one possible implementation, refer to Figure 5, S15 can be superimposed and integrated by the following steps.

[0108] S151, based on the metal ball, determine the same position point of the first superimposed data and the surface scan data.

[0109] S152, based on the same position point, the first superimposed data and the face scan data are superimposed and integrated to obtain the second superimposed data. Since the face scan data includes data when the mouth contains the bite record silicone rubber provided with a metal ball, and the first superimposed data also includes data when the mouth contains the bite record silicone rubber provided with a metal ball (i.e., silicone rubber mouth scan data). Therefore, in S151, based on the metal ball in the first superimposed data and the metal ball in the face scan data, the same position point of the same metal ball can be found in the first superimposed data and the face scan data, and then in S152, based on multiple groups of the same position points, the first superimposed data and the face scan data are superimposed and integrated (mainly the pre-processed CBCT data of the first superimposed data and the face scan data are superimposed) to obtain the second superimposed data.

[0110] Through the above steps S151 to S152, the first superimposed data and the face scan data can be accurately superimposed, which can avoid superposition errors to a certain extent and help improve the compatibility between the tooth arrangement plan and the tooth arrangement object.

[0111] When arranging teeth in full mouth, it is necessary to determine the size and shape of the denture, the midline, the maxillary plane, the position of the maxillary canines, the position of the incisor tips of the upper anterior teeth, and the inclination of the protruding condyle. Figure 6 , step S17 can be implemented as the following steps.

[0112] S171, combining with the virtual frame, based on the pre-processed CBCT data in the second superimposed data, measure the anterior condylar guide inclination.

[0113] S172, selecting the incisor tip position of the upper front teeth from the first face scan data in the second superimposed data as the incisor tip position of the upper front teeth of the denture.

[0114] Among them, the cutting end position is 0mm to 2mm below the lip of the tooth arrangement object.

[0115] S173, determining the maxillary plane of the denture based on the preprocessed CBCT data and the position of the incisor tip of the upper anterior teeth in the second superimposed data.

[0116] S174, determining the position of the maxillary canines of the denture based on the position of the mouth corners in the first face scan data and the second face scan data in the second superimposed data.

[0117] S175, determining the center line of the denture based on the silicone rubber mouth scan data and the face scan data in the second superimposed data.

[0118] S176, determining the size and shape of the denture based on the first surface scan data, the second surface scan data and the third surface scan data in the second superimposed data.

[0119] In the above steps S171 to S176, S173 must be executed after S172, and the order of S171, S172, S174, S175 and S176 can be swapped at will or executed simultaneously.

[0120] In step S171, SolidWorks software can be used to draw a cylinder, and a plane passing through the cylinder is established with the length direction of the cylinder as the axis, and the cylinder is combined with the plane to obtain an auxiliary file in STL format.

[0121] For example, you can call "Sketch" → "Circle" to draw a circle with a diameter of 1-4mm. Then select "Feature" → "Extrude Base / Boss" to extrude the circle to form a cylinder with a length of 13-20cm. At the same time, through the cylinder, a plane is established with the length of the cylinder as the axis. The thickness of the plane is 0.1mm, and the length and width are both 13-20cm. Combine the cylinder and the plane and save them as an STL file.

[0122] Import the auxiliary file and the pre-processed CBCT data in the second superimposed data into the exocad software, and perform data superposition matching, so that the cylinder passes through the center of the bilateral condyles in the pre-processed CBCT data, and the axial direction of the cylinder moves to the position corresponding to the virtual frame. Continue to rotate the cylinder and the plane so that the plane is parallel to the orbital-auricular plane on the CBCT at the same time.

[0123] On the basis of the above, make a reference plane parallel to the anterior inclined plane of the superior condylar fossa in the pre-processed CBCT data, call the measurement tool of the exocad software to measure the angle between the reference plane and the plane attached to the cylinder, and you can get the anterior condylar inclination, which represents the tooth movement data of the tooth arrangement object.

[0124] In step S172, the incisor tip position of the upper front teeth refers to the position 2 mm below the lip, that is, the position 0 mm to 2 mm below the upper lip from the lower edge of the upper lip in the first face scan data can be used as the incisor tip position of the upper front teeth.

[0125] Generally, it is considered that the plane is parallel to the alar-tragus line and forms an angle of 15° with the orbitotragus plane, and the compensation curve of the maxillary dentition is a part of the Monson sphere. Therefore, in step S173, the alar-tragus line, the orbitotragus plane and the Monson sphere can be marked based on the preprocessed CBCT data of the second superimposed data, that is, in the preprocessed CBCT data of the second superimposed data, and then the alar-tragus line, the orbitotragus plane and the Monson sphere are connected and fitted to obtain the maxillary plane or curve of the denture.

[0126] In step S174, the positions of the corners of the mouth in the first and second face scan data in the natural resting state and the smiling state (ie, the lips are relaxed) can be used as the distal ends of the maxillary canines to determine the positions of the maxillary canines.

[0127] In step S175, the facial midline, lip frenulum and mid-palatal suture can be determined from the silicone rubber mouth scan data and the face scan data in the second superimposed data, and the facial midline, lip frenulum and mid-palatal suture are fitted according to preset rules to obtain the midline of the denture.

[0128] In the traditional method of tooth arrangement, the midline is determined based on the palatal suture and lip frenulum on the plaster model. However, sometimes the intraoral midline and the facial midline are inconsistent. However, traditional tooth arrangement only has the intraoral morphology and no facial information to refer to, so the tooth arrangement effect may not be satisfactory.

[0129] Compared with traditional tooth arrangement, S175 will use facial scan data as a reference, and fit the facial midline determined by the facial scan data and the lip frenulum and mid-palatal suture determined by the silicone rubber mouth scan data to obtain the midline, thereby improving the accuracy of the midline.

[0130] In S176, the labial curvature between the two sides of the mouth corner lines in the first face scan data (facial data in a natural resting state) in the second superimposed data can be used as the width of the upper front teeth 3-3, so as to determine the width of the denture. At the same time, the facial morphology of the tooth arrangement object is identified based on the first face scan data, the second face scan data and the third face scan data in the second superimposed data, and then the tooth shape corresponding to the facial morphology is used as the shape of the denture.

[0131] The upper front teeth 3-3 refers to the two maxillary incisors and the lateral incisors adjacent to the two incisors, a total of six teeth.

[0132] The facial morphology of the tooth arrangement object can be identified by machine learning model recognition or manual recognition. The tooth shape corresponding to each facial morphology can be preset or generated by machine learning model, which is not specifically limited in this embodiment.

[0133] After determining the tooth arrangement parameters (i.e., the size and shape of the denture, the midline, the maxillary plane, the position of the maxillary canines, the position of the incisor tips of the upper anterior teeth, and the inclination of the protruding condyle), the virtual frame of the first auxiliary tool can also be used to check the occlusal function, and perform virtual adjustments based on the protruding condyle inclination of the denture to eliminate interference points in the tooth arrangement.

[0134] For example, you can call the "Advanced Mode" → "Tools" → "Start Articulator" function of the exocad software, select the Artex CR type for the articulator type, and move the second superimposed data as a whole so that the condyle of the virtual frame is aligned with the condyle superimposed in the pre-processed CBCT data, and the upper surface plane of the virtual frame is flush with the orbital-auricular plane. At the same time, input the obtained protruding condylar guide inclination, start the "Start Simulating Occlusal Movement" function, and complete the process of transferring the virtual articulator. Then, start the articulator, and when the interference points on the denture during the occlusal movement are displayed, call the "Adjust Occlusal High Point" function to complete the automatic adjustment.

[0135] The full denture tooth arrangement method provided in the present application integrates face scan data under various facial states, upper and lower jaw mouth scan data, silicone rubber mouth scan data of bite record silicone rubber, and oral CBCT data of the tooth arrangement subject when the bite record silicone rubber is in the mouth, so as to scientifically arrange teeth based on rich tooth arrangement information, greatly optimize the tooth arrangement process, improve the adaptability of the tooth arrangement plan, and reduce the number of tooth arrangement times and tooth arrangement costs. In addition, the tooth arrangement process is standardized, and the tooth arrangement does not need to rely on the experience level of professionals. The tooth arrangement operation is simple, which is convenient for subsequent inspection and can reduce the length of tooth arrangement time. Therefore, it can solve the problems existing in the prior art, such as few references, cumbersome operation, high technical sensitivity, and inconvenient inspection.

[0136] In addition, it is conducive to detail adjustment, convenient for aesthetic prediction, and can improve the patient's satisfaction with tooth arrangement.

[0137] Based on the same inventive concept as the above-mentioned full denture tooth arrangement method, in a possible implementation, a full denture tooth arrangement device 40 is also provided. Figure 7 , may include a data acquisition module 401, a first superposition module 402, a second superposition module 403 and a tooth arrangement module 404.

[0138] The data acquisition module 401 is used to acquire the upper and lower jaw mouth scan data of the tooth arrangement object, the oral CBCT data of the bite record silicone rubber in the mouth, and the face scan data in various facial states, and acquire the silicone rubber mouth scan data of the bite record silicone rubber. The bite record silicone rubber records the occlusal relationship of the tooth arrangement object.

[0139] The first superposition module 402 is used to align the upper and lower jaw mouth scan data and the silicone rubber mouth scan data, reconstruct and trim the oral CBCT data to obtain pre-processed CBCT data, and superimpose and integrate the pre-processed CBCT data with the aligned upper and lower jaw mouth scan data and the silicone rubber mouth scan data to obtain the first superposition data.

[0140] The second superposition module 403 is used to superimpose and integrate the first superposition data with the face scan data to obtain second superposition data.

[0141] The teeth arrangement module 404 is used to perform teeth arrangement positions and denture parameters based on the second superposition data to obtain a teeth arrangement plan.

[0142] In the above-mentioned full denture tooth arrangement device 40, through the coordinated action of the data acquisition module 401, the first overlapping module 402, the second overlapping module 403 and the tooth arrangement module 404, standardized tooth arrangement can be achieved without relying on the technician's wellbore and level, and the tooth arrangement operation is simple, so that standardized inspection can be carried out after the tooth arrangement, thereby improving the time-consuming problem of the current tooth arrangement method.

[0143] In addition, by recording the facial expressions of the tooth arrangement object in various facial states, the second superimposed data of more accurate upper and lower jaw spatial position relationship and the median position relationship of the upper and lower jaws are also recorded to perform tooth arrangement position and denture parameters, so that the tooth arrangement position determined based on the second superimposed data is more adapted to the tooth arrangement object, and the tooth arrangement process is optimized, which can improve the adaptability between the tooth arrangement plan and the tooth arrangement object and customer satisfaction, thereby reducing the number of tooth arrangement times and reducing the cost of tooth arrangement.
