[0028] The technical solution of the present disclosure is further described in detail below through the accompanying drawings and embodiments.

[0029] The inventors have found that the design and production process of oral restorations in the related art requires a long consultation time, and is often more inclined to meet the patient's functional reconstruction needs, and has a lower degree of satisfaction with aesthetic needs; there is limited room for adjustment after the oral restoration is completed, and the patient's consultation costs and duration are further increased.

[0030] In response to the above-mentioned problems, the present disclosure proposes a method, device, production system and storage medium for generating an oral restoration, which can apply the design and adjustment operations of a virtual model to the design process of the oral restoration, so that the oral restoration can be presented intuitively on the basis of meeting the user's functional reconstruction needs, so that doctors and patients can intuitively know the appearance of the possible oral restoration in advance, so as to make personalized choices or adjustments, simplifying the manual operations in the traditional process, eliminating the repeated trial-wearing process, simplifying the process of oral restoration, and improving the degree of personalization of the restoration obtained.

[0031] The oral prosthesis mentioned in the present disclosure includes a denture or a removable partial denture fixed in the patient's mouth, such as a removable partial denture including at least the middle four teeth of the upper or lower jaw.

[0032] The flowcharts of some embodiments of the method for generating an oral restoration disclosed in the present invention are as follows: Figure 1 As shown, steps S11-S15 are included.

[0033] In step S11, the patient's upper and lower jaw static data and the lower jaw movement trajectory data are obtained.

[0034] The static data of the upper and lower jaws may include the three-dimensional morphological data of the upper and lower jaw dentition and the occlusal relationship data. In some embodiments, the static data of the upper and lower jaws of the patient may be collected by an oral scanning (oral scanning) device.

[0035] The mandibular motion trajectory data can be obtained by any method in the relevant technology. In some embodiments, the patient can be asked to perform a specified mandibular motion or an arbitrary mandibular motion, and the mandibular motion trajectory captured in the image can be extracted by image acquisition. In some embodiments, the patient can be asked to wear a device with a sensor or a positioning point, and the mandibular motion trajectory data of the patient can be obtained by collecting the position change information of the sensor or the position change information of the positioning point during the patient's specified mandibular motion or an arbitrary mandibular motion.

[0036] In step S12, facial morphology data of the patient is obtained. In some embodiments, the facial morphology data of the patient can be obtained by three-dimensional image acquisition.

[0037] There is no fixed execution order for the above steps S11 and S12, and the execution order can be set arbitrarily as needed.

[0038] In step S13, a virtual patient model is generated based on the upper and lower jaw static data, the lower jaw movement trajectory data and the facial morphology data.

[0039] For example, Figure 2 The data required to generate a virtual patient model and the method of obtaining the data are shown in FIG. The facial morphology data 21 is obtained by acquiring a static facial image; the upper and lower jaw static data 22 are obtained by scanning the patient's oral cavity with an oral scanning instrument; and the patient's mandibular motion trajectory data 23 is obtained by acquiring the anterior tooth area data with landmarks. Furthermore, the above data 21, 22, and 23 are combined to obtain a virtual patient model 20.

[0040] In some embodiments, based on the obtained mandibular motion trajectory data, mandibular motion trajectory features can be further extracted, and facial features can be obtained based on facial morphology data. Based on the mandibular motion trajectory features and facial features, at least one of the positions with the highest repeatability of mandibular movement or the physiological posterior position is determined to determine the patient's jaw relationship. Based on the facial morphology data, upper and lower jaw static data, and jaw relationship, a virtual patient model is generated that includes the patient's facial morphology data, upper and lower jaw static data, and conforms to the jaw relationship. Based on the method in the embodiment shown above, a virtual patient model that conforms to the patient's jaw relationship can be obtained, which conforms to the user's mandibular movement habits, so that the subsequently generated trial model can meet the user's functional reconstruction needs.

[0041] In step S14, a trial model is obtained based on the oral restoration template model and the virtual patient model, for example, the two models are merged into one model as a trial model.

[0042] In some embodiments, the oral restoration template model can be combined with the virtual patient model by key point matching to serve as a trial model, thereby improving the credibility of the trial model.

[0043] In some embodiments, multiple types of oral restoration templates can be set, each of which has at least one oral restoration template model, which is stored in the database and indexed by the type identifier of the template. Different types of oral restoration templates have different appearance characteristics. For example, Figure 3 The figure shows the outer contour lines of the anterior dentition of six styles of oral restoration template models, which are respectively called beautiful type, dignified type, elegant type, handsome type, resolute type, and bionic type as shown in (a)-(f).

[0044] Beautiful type (a): The bottom of the four teeth in the middle is straight, the edges of the two teeth in the middle are vertical, the lower left corner of the left tooth in the middle and the lower right corner of the right tooth are rounded right angles, and the edges of the other two teeth in the middle are slightly curved vertically. Through actual wearing and clinical experience, wearing a beautiful type of oral restoration can present a graceful, pure and youthful appearance.

[0045] Dignified type (b): The bottom of the four teeth in the middle is straight, the connection between the two teeth in the middle is a vertical structure, the radius of curvature of the vertical curvature of the edges on both sides is larger than the radius of curvature of the vertical curvature of the two teeth in the middle of the elegant type, and the edges of the other two teeth in the middle four are slightly curved vertically. Through actual wearing and clinical experience, it is concluded that wearing a dignified type of oral restoration can present a horizontal, vertical, full and correct appearance.

[0046] Elegant type (c): The bottom of the four teeth in the middle is straight, the connection between the two teeth in the middle is a vertical structure, the lower part of the two sides has a large vertical curvature, and its curvature radius is smaller than the vertical curvature radius of the two sides of the dignified type. The other two teeth in the middle are slightly curved vertically. Through actual wearing and clinical experience, wearing an elegant oral restoration can present a soft, beautiful, elegant and generous appearance.

[0047] Handsome type (d): The bottom of the four teeth in the middle is straight, the connection between the two teeth in the middle is a vertical structure, and the edges on both sides are slightly curved vertically. The edges of the other two teeth in the middle are slightly curved vertically: the left bottom of the left tooth moves slightly upward, and the lower left corner is a blunt angle with a sharp tip, and the right bottom of the right tooth moves slightly upward, and the lower right corner is a blunt angle with a sharp tip. Through actual wearing and clinical experience, it is concluded that wearing a handsome type of oral restoration can present an appearance that is square inside and round outside, and both hard and soft.

[0048] Fortitude type (e): The bottom of the four teeth in the middle is straight, the gap between the two teeth in the middle is smaller than that of the dignified type, elegant type, and handsome type, the connection between the two teeth in the middle is a vertical structure, and the edges on both sides are slightly curved vertically, and the edges of the other two teeth in the middle are slightly curved vertically: the lower left corner of the left tooth is a blunt-angle type with a sharp tip, and the angle is smaller than the corresponding position of the handsome type, and the lower right corner of the right tooth is a blunt-angle type with a sharp tip, and the angle is smaller than the corresponding position of the handsome type. Through actual wearing and clinical experience, it is concluded that wearing a fortitude type oral restoration can present a sharp-edged and majestic appearance.

[0049] Bionic type (f): The middle of the lower end of the two middle teeth is slightly concave upwards, and the six teeth are slightly unevenly arranged. Through actual wearing and clinical experience, it is concluded that wearing bionic oral restorations can present a natural, harmonious, and lifelike appearance.

[0050] The above classification of template types is only an example of feasible implementation, and the names are only exemplary names set according to the appearance characteristics of each template. The types of oral restoration templates are not limited to the above 6 types, and the names of template types are not limited to the names mentioned above.

[0051] In some embodiments, in step S14, the doctor may recommend or the patient may select one or more oral restoration templates, and a trial model may be generated based on the selected oral restoration template model and the virtual patient model. This can achieve the trial effect of the oral restoration while avoiding excessive computational overhead and improving data processing efficiency.

[0052] In some embodiments, in step S14, each type of oral restoration template model can be combined with the virtual patient model respectively, so as to obtain a trial model including a model of the corresponding type of oral restoration, and the number of the obtained trial models matches the number of the adopted oral restoration template models. Through such a method, trial models including different appearance characteristics can be generated, so that the wearing effect of the oral restoration based on different oral restoration templates can be intuitively reflected, which increases the patient's choice space and is conducive to improving user satisfaction.

[0053] In some embodiments, in step S14, a pre-trained machine learning model can be used to identify key points in the virtual patient model, and then the key points of the pre-labeled oral restoration template model are aligned with the key points in the virtual patient model to obtain a trial model. For example, based on virtual patient images collected in clinical research, the key points therein are labeled and used as training samples to train the machine learning model to obtain the above-mentioned pre-trained machine learning model. The labeled key points can be positions that are associated with or overlap with the oral restoration template, so as to be aligned with the key points on the oral restoration template model. Through such a method, the degree of adaptation between the oral restoration model in the trial model and the virtual patient model can be improved, and the reliability of the trial model can be improved.

[0054] In some embodiments, considering that different patients' oral cavity have differences in size, curvature angle, etc., when aligning the key points of the oral restoration template model with the virtual patient model, the oral restoration template model can be adjusted as a whole or in part, for example, the overall size or the size of some teeth can be adjusted, and the relative positions between different areas (including distance, relative angle, relative height, etc.) can be adjusted. Through the overall or local adjustment, the key points of the pre-marked oral restoration template model are aligned with the key points in the virtual patient model. Through the method in the above embodiment, the degree of adaptation between the oral restoration model in the trial model and the virtual patient model can be further improved, ensuring that the oral restoration obtained based on the oral restoration model can be applied to the patient and achieve the same appearance effect as the trial model, thereby improving the reliability of the trial model.

[0055] In step S15, an image of the fitting model is displayed, for example, by means of a screen or a three-dimensional projection, to display an image of at least the front angle of the fitting model. In some embodiments, the fitting model is a three-dimensional model, and the angle of presentation can be changed by automatic playback or manual adjustment to increase the amount of appearance features that can be provided by the image, thereby providing more abundant information for doctors and patients to make choices.

[0056] In some embodiments, if multiple trial models are generated in step S14, images of all the trial models are displayed to the patient for the patient to select. This approach can improve the compliance of the oral restoration with user needs and improve the personalization of the oral restoration.

[0057] Based on the method in the embodiment shown above, a virtual patient model can be generated that takes into account both the user's appearance characteristics and the user's oral function reconstruction needs. On the basis of the virtual patient model, an oral restoration template model is combined, so that the effect of the patient wearing an oral restoration of the corresponding template type that meets the patient's oral function reconstruction can be intuitively presented, thereby simultaneously meeting the patient's functional reconstruction and aesthetic needs, simplifying the oral restoration process, and improving the degree of personalization of the restoration obtained.

[0058] Flow charts of other embodiments of the method for generating an oral restoration disclosed herein are as follows: Figure 4 As shown, steps 401-409 are included.

[0059] In step 401, the patient's upper and lower jaw static data and the lower jaw movement trajectory data are obtained.

[0060] In step 402, facial morphology data of the patient is obtained.

[0061] In step 403, a virtual patient model is generated based on the upper and lower jaw static data, the lower jaw movement trajectory data and the facial morphology data.

[0062] The above steps 401 - 403 are the same as or similar to the above steps S11 - S13 .

[0063] In step 404, each type of oral restoration template model is combined with the virtual patient model to obtain a trial model including a model of the corresponding type of oral restoration.

[0064] In some embodiments, each type of oral restoration template mentioned above refers to multiple types selected based on the template types stored in the database, or each template type stored in the database.

[0065] In some embodiments, a doctor may recommend or the patient may select one or more oral restoration templates, and a trial model may be generated based on the selected oral restoration template model and the virtual patient model. This can achieve the trial effect of the oral restoration while avoiding excessive computational overhead and improving data processing efficiency.

[0066] In some embodiments, the oral prosthesis template models of each template type stored in the database are respectively combined with the virtual patient model to obtain trial models including models of the corresponding type of oral prosthesis, and the number of trial models obtained matches the number of oral prosthesis template models used. Through such a method, trial models including different appearance features can be generated, so that the wearing effects of oral prostheses based on different oral prosthesis templates can be intuitively reflected, which increases the patient's choice space and is conducive to improving user satisfaction.

[0067] In step 405, the images of all the trial models generated are displayed to the patient. In some embodiments, the trial models are three-dimensional models, and the angle of presentation can be changed by automatic playback or manual adjustment to increase the amount of appearance features that can be provided by the images, providing more abundant information for doctors and patients to make choices.

[0068] In some embodiments, a human-computer interaction interface may be provided during the presentation process for the patient to select. In some embodiments, the name of the template type corresponding to each trial model may be marked during the presentation process so that the patient can quickly understand the presentation effect of the appearance of the template of that type.

[0069] In step 406, the trial model selected by the user according to the displayed image of the trial model is obtained. In some embodiments, an instruction obtained through a human-computer interaction interface can be received to determine a corresponding trial model, and the trial model is used as the target wearing effect that the patient hopes to achieve.

[0070] In step 407, the oral restoration model included in the selected trial model is used as the target oral restoration model.

[0071] In some embodiments, the oral restoration model in the trial model is separated as the target oral restoration model, or the oral restoration model that successfully matches the key points of the virtual patient model in the above step 404 and is used to generate the selected trial model is extracted as the target oral restoration model. Through such a method, an oral restoration model that matches the virtual patient model and conforms to the patient's jaw position can be obtained, thereby improving the matching degree between the model and the patient and reducing the burden of subsequent processing.

[0072] In step 408, the target oral restoration model is adjusted according to at least one of the dental expertise or the patient's opinion, and restoration design data is generated. This method can further improve the ability of the designed oral restoration to reconstruct the patient's oral function and its adaptability to the patient's needs, reduce the probability of requiring secondary adjustments after the oral restoration is completed, and improve the efficiency of oral restoration and the degree of personalization of oral restorations.

[0073] In some embodiments, according to the doctor's judgment and the patient's needs, step 408 can be skipped, that is, the data of the target oral restoration model is directly used as the restoration design data.

[0074] Based on the method in the embodiment shown above, a plurality of trial models of different styles can be generated for patients to choose from. Patients can select the required trial models based on their own facial features, personal preferences and personality, and then determine the corresponding oral restoration model, thereby providing a data basis for producing oral restorations that meet both functional reconstruction needs and aesthetic and user needs, thereby improving the efficiency of oral restoration design and production.

[0075] In some embodiments, Figure 4 As shown, the method for generating an oral restoration disclosed in the present invention further includes step 409 .

[0076] In step 409, the oral prosthesis of the patient is manufactured according to the prosthesis design data. For example, the prosthesis design data can be used as input data and input into a 3D printer, and the 3D printer can quickly print out the oral prosthesis.

[0077] In some embodiments, the printer can first print out a resin diagnostic wax-up model, let the patient try it on and feel the final restoration effect, for example, the patient can be asked to make adjustment suggestions from the perspective of wearing comfort. The diagnostic wax-up model can be adjusted according to the adjustment suggestions, and the patient can be further tried on until the patient is satisfied. The final adjusted result is used to make the finished oral restoration, thereby further improving the fit between the oral restoration and the patient; avoiding adjustments to the finished oral restoration and reducing the difficulty of adjustments can also reduce the patient's medical costs and shorten the time of medical treatment.

[0078] Through the method in the embodiment shown above, the accuracy and efficiency of oral aesthetic diagnosis can be improved, the influence of human factors on the design results can be reduced, and patients can be provided with a faster and more personalized oral aesthetic treatment plan.

[0080] In one embodiment, it is also possible to Figure 6 As shown, the oral restoration generation device 600 includes a memory 601 and a processor 602. The processor 602 is coupled to the memory 601 via a BUS bus 603.
