And, unless specified to the contrary, references to "first," "second," etc. ordinal words of embodiments of the present application are used for distinguishing between multiple objects and are not used for limiting the order, timing, priority, or importance of the multiple objects.

Reference in the specification to "one embodiment" or "some embodiments" or the like means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless expressly specified otherwise.

As background, more and more people currently prefer to select the invisible orthodontic as the first choice of the orthodontic method, and because the invisible orthodontic generally customizes a personalized orthodontic scheme for a patient, in order to maintain the orthodontic effect of the teeth, improve the comfort of the patient, etc., a passive orthodontic appliance may need to be worn at some stage of the orthodontic to maintain the orthodontic effect of the current teeth.

Specifically, the dental appliance is manufactured as shown in FIG. 1 below. The method comprises the steps of scanning teeth of a patient to obtain tooth state data of the patient, correcting the tooth state data of the patient based on manual correction of operators such as doctors and the like to generate a tooth correction scheme aiming at individuals of the patient, providing various adding requirements of a passive tooth correction device after the operators such as doctors and the like fully communicate with a tooth correction designer according to the tooth correction scheme, modeling the tooth state data according to the requirements and the tooth correction scheme by the designer to obtain a corrected digital tooth model, further manufacturing a corresponding solid tooth model by using a numerical control machine tool processing method or a rapid molding method based on the digital tooth model, and pressing the corresponding tooth correction device for a male mold according to the solid tooth model. In this way, a corresponding dental appliance may be generated according to the dental condition of the patient. However, in the aspect of adding the passive dental appliance, as doctors and designers need to communicate with respect to the adding positions, adding quantity and the like of the passive dental appliances, the efficiency of generating the dental appliances according to the dental appliance scheme is reduced, the period is prolonged, the design efficiency of the invisible dental appliance is reduced, and in the process of correcting, if the quantity of the passive appliances needs to be newly increased or reduced, the doctors need to carry out corresponding judgment and then confirm with patients, and communicate with the designers to determine the new dental appliance scheme, so that the design efficiency of the dental appliance is low and the production speed is slow. Further, when the passive appliance is added, the digital model of the teeth cannot embody the updated complete tooth appliance period, so that the user cannot directly feel the duration of each tooth appliance step and the wearing period of the passive appliance.

Based on the above, the embodiment of the application provides a display method of a dental correction scheme, which improves the generation rate of the dental correction scheme by displaying a first dental correction scheme of a patient on a first operation interface and updating the first dental correction scheme according to multi-pressure step function operation to obtain a second dental correction scheme.

Step 202, the client responds to the operation of the multi-step function and displays a first operation interface.

The first operation interface is used for guiding the first correction step to be added at the position corresponding to at least one correction step of at least one correction stage in the first tooth correction scheme, and the first correction step is used for maintaining the current correction position of the teeth of the patient.

Specifically, the first dental appliance includes a plurality of different stages, each stage having a different function, for example, the first dental appliance may include an initial stage for indicating that the patient has not worn the dental appliance for dental appliance, a dental stage for indicating that the patient has worn the dental appliance for dental appliance and that the position of the patient's teeth moves with the dental appliance, and an over-correction stage for indicating that the patient's teeth are stabilized in a target movement position during dental appliance. To ensure that these dental appliance stages are each effective in correcting the teeth, it is often necessary to add a corresponding multi-step operation during these stages, which is generally indicative of the operation resulting from the first appliance, which is indicative of the appliance stage in which the tooth position is fixed using the passive dental appliance.

In one possible implementation, the client displays a first pop in response to the opening of the multi-step function, wherein the opening of the multi-step function is performed by the operation of the multi-step function area 305, for example, the opening of the multi-step function may be performed by an operator clicking a multi-step function button in the multi-step function area 305 or by the operator selecting the multi-step function button in a pop-up option bar by clicking a right mouse button after a corresponding tooth appliance or after a digital tooth model, and the application is not limited thereto, the first pop includes at least one candidate area of at least one appliance stage in a first tooth appliance scheme for guiding the addition of at least one candidate appliance position of the first appliance, the client displays a first appliance of the candidate first appliance in response to the operation of the candidate area of the multi-step function, the first control for indicating the operation of the number of the first appliance, and the client determines the number of the first appliance in response to the operation of the first control.

In this way, all correction steps of the second tooth correction scheme are displayed on the second interface so as to be browsed and operated by operators and patients, a clearer visual platform is provided for the tooth correction scheme, and meanwhile, the efficiency of adding new first correction steps is improved.

In one possible implementation, the client is responsive to a second operation on a second dental appliance, and when it is determined that a second trigger condition is met, a third interface is displayed, the third interface including a display area of a digital dental model of the patient and a display area of a step bar of a portion of the first appliance in the second dental appliance, the second trigger condition including at least one of a selection operation of the first appliance, or a phase display requirement of the first appliance.

Specifically, the third interface is shown in fig. 6 below, and includes a digital dental model 601 of the patient, a display area 602 of a step bar of the first correction step in the second tooth correction scheme, or the second interface may further include other parts, for example, an operation area 603, a view angle switching area 604, a multi-step function area 605, and the like, where the step bar area 602 of the first correction step includes a part of the first correction step in the second tooth correction scheme, and is sequentially arranged in the order of the tooth correction period. For example, the first step bar 602 may display only the first step after the third step, before the fourth step, or may display only the first step after the second step, or may display only the first step after the fourth step, in addition to the second step, the third step, and the fourth step, as illustrated in fig. 6, the first step after the third step, and before the fourth step is displayed in fig. 6, and the first step after the third step, and before the fourth step is displayed in the second tooth plan is illustrated, for example, if the first step is the region of the 1 st, 6 th to 7 th, and 13 th steps, respectively, wherein the first step after the third step, before the fourth step is the 6 th to 7 th steps, and thus the step bar display area 602 includes the second step 0 representing the initial step, the third step 2 to 5 representing the tooth stage, and the fourth step 7 representing the fourth step 8 th step 8-11 representing the first step 6 to 7 th step of the multiple steps.

Further, the hidden first correction step may be displayed in a prompt manner, for example, the hidden first correction step 1 and the first correction step 12 in the figure are displayed in corresponding positions in the step bar in a corner mark manner for the operator to view. It should be noted that the above manner is only an example, and the position of the hidden first correction step may be indicated by other manners, for example, the indication is performed by a light color step bar, or the position of the hidden first correction step may not be indicated, which is not limited by the present application.

In a possible implementation manner, the position where the first correction step can be added may be indicated in the step bar area 602, as shown in fig. 6, an area where the first correction step can be added is still left between the first correction step 7 and the fourth correction step 8, so the step bar area 602 displays the area where the first correction step can be added by a dotted line step bar to indicate to the operator that the first correction step can be added in the corresponding area, and it should be noted that the dotted line step bar is only an example, the position where the first correction step can be added may be indicated by other means, for example, the position area where the first correction step can be added may be marked by a light color corner mark, and the like.

Further, the second triggering condition includes a selection operation of the first correction step, for example, by selecting a part of multi-step operation in the second tooth correction scheme in the operation area 603, and specifically selecting an area of the first correction step to be displayed, a digital tooth model of the second tooth correction scheme and a step bar including the first correction step are displayed on the third interface, or the second triggering condition further includes a stage display requirement of the first correction step, for example, the server sends a display requirement of the first correction step to the client, and the client displays the third interface after responding to the requirement. It should be noted that the second triggering condition may also include other contents, for example, by clicking a right mouse button on the step bar or the digital tooth model, and selecting a corresponding operation for expanding the first correction step in a right mouse button option field, which is not limited in the present application.

In this way, the application displays the part of the first correction step in the second tooth correction scheme independently, provides a clearer period for patients to wear the passive correction device, and simultaneously, allows operators such as doctors to evaluate the progress of the second tooth correction scheme according to the wearing period of the passive correction device, and timely and efficiently acquires the tooth treatment scheme of the patients.

In one possible embodiment, the client is responsive to a third operation on the second dental appliance, and upon determining that a third trigger condition is met, displays a fourth interface comprising a display area of the digital dental model of the patient and a display area of a step bar of the second dental appliance that removes the first appliance, the third trigger condition comprising at least one of a hiding operation of the first appliance, or a dental deviation comparison analysis requirement of the dental appliance phase of the patient.

Specifically, the fourth interface is shown in fig. 7 below, and includes a digital dental model 701 of the patient, where a display area 702 of a step bar of the second dental correction scheme of the first correction step is removed, or the second interface may further include other parts, for example, an operation area 703, a view angle switching area 704, a multi-step function area 705, and the like, where the display area 702 of the step bar includes an initial step and all correction steps with movement amounts in the second dental correction scheme, that is, the second correction step, the third correction step, and the fourth correction step, which are sequentially arranged in order before and after the dental correction period. For example, as can be seen from FIG. 5, the second appliance is the area of step 0, the third is the area of steps 2-5, and the fourth is the area of steps 9-12 in the second dental appliance, so the step bar display area 702 includes the second appliance 0 representing the initial step, the third appliance 2-5 representing the dental appliance stage, and the fourth appliance 9-12 representing the overcorrection stage. It should be noted that since only the portions of the second, third, and fourth appliances are present in the fourth interface, the fourth interface is used to illustrate the portions of the dental appliance that need to be worn in a dental appliance regimen.

Further, the third triggering condition includes a hiding operation of the first orthodontic step, for example, by selecting a multi-step operation in the second orthodontic scheme in the operation area 703, hiding the digital dental model of the second orthodontic scheme and the step bar including the first orthodontic step, or the second triggering condition further includes a dental deviation comparison analysis requirement of the orthodontic stage, for example, when the patient or doctor needs to perform the comparative analysis of the orthodontic stage, the server sends the dental deviation comparison analysis requirement of the orthodontic stage to the client, and the client responds to the requirement and displays the dental deviation comparison analysis requirement on the fourth interface. It should be noted that the third triggering condition may further include other contents, for example, by clicking a right mouse button on the step bar or the digital tooth model, and selecting a corresponding operation of hiding the first correction step in the right mouse button option field, which is not limited in the present application.

In this way, the first correction step which is only used for keeping the tooth position stable is hidden, only the movement amount in the tooth correction scheme is displayed, namely the step that the teeth move is realized, so that the wearing condition of the tooth correction device of each period of a patient is detected, and meanwhile, each stage of the tooth correction scheme can be clearly displayed to the patient, so that the tooth correction device is convenient to manufacture, and the period that the patient knows the teeth is more convenient to learn.

In one possible implementation, the client responds to the adding operation of the first correction step, sends the adding operation item of the first correction step to the server, and receives a first response message from the server and displays an interface of the first response message when the adding operation does not meet the first condition. Or when the adding operation does not meet the second condition, receiving a second response message from the server side and displaying an interface of the second response message, wherein the first response message exceeds the design scheme requirement of the dental appliance product, and the second response message adds more than a step number limiting threshold value for the step number of the first correction step.

Specifically, the interface of the first response message is shown in fig. 8, when the adding operation does not meet the first condition, that is, the requirement of the product design scheme of the dental appliance is not met, the server sends the first response message to the client, the client receives the first response message from the server and displays the interface of the first response message, for example, the first condition is generally that the number of steps limited by the product design scheme of the dental appliance, for example, the product design scheme of a patient comprises 10 dental appliances (including passive appliances), and the patient uses 3 dental appliances in the third and fourth appliances respectively, the remaining 4 dental appliances in the scheme can be used for adding the first appliances, at this time, if the number of the first appliances selected by the multiple-step operation is greater than 4, the adding operation is regarded as not meeting the first condition, the first response message interface is displayed, the first control plus sign in the gray state in the first control plus sign is not selected, so as to avoid the operator from continuing to increase the first appliances, and the patient is prompted by the first response message interface to prompt that the patient has the additional appliances according to the current operating cost. It should be noted that the above described scheme is only an example and that other dental appliances may exist, and the application is not limited thereto.

Further, as shown in fig. 9 below, when the adding operation does not meet the second condition, that is, the step number limiting threshold is not met, the server sends the second response message to the client, the client receives the second response message from the server and displays the interface of the second response message, the first control plus sign in the interface of the second response message is grey and is in an unselected state, so as to avoid the operator from continuing to add the first correction steps, for example, the second condition is generally the step number limiting threshold of the first correction steps added by the multi-step operation, as shown in fig. 9, generally, the operator is set to add at most five first correction steps, and the operator can increase the number of adding the first correction steps by increasing the authority of the operator, for example, after logging in by using a whitelist user account or an administrator user account. When the number of the added first correction steps reaches the step number limiting threshold, displaying an interface of the second response message, and prompting that the addition of the first correction steps cannot be continued. It should be noted that the above five steps are only examples, the limiting threshold of the first correction step is determined by the operator according to the patient's own situation, the dental appliance supply situation, and the like, which is not limited by the present application, and the above whitelist account and the administrator account are only examples, which is not limited by the present application.

Based on the same technical concept, the embodiment of the application provides a method for manufacturing a dental appliance, the method performs the manufacturing process of the dental appliance through the process of the display method of the dental appliance scheme, the method is executed by computing equipment, the computing equipment can be understood as equipment such as a computer, and the process of the method is shown in the following figure 10.

In step 1001, a computing device obtains oral scan data of a target subject.

Firstly, the computing device scans and determines the oral cavity information of the target object by means of X-ray, nuclear magnetic resonance and the like on the oral cavity of the target object, and then generates corresponding oral cavity scanning data and a digital oral cavity model according to the oral cavity information. The digital tooth model is presented by way of a facial modeling in which each tooth surface is made up of a plurality of triangular facial patches.

At step 1002, the computing device determines a first dental correction regimen for a patient based on oral scan data.

Specifically, after obtaining the digital tooth model, the computing device determines a target position of the final movement of the patient's teeth according to the digital tooth model of the patient, and designs a dedicated tooth correction scheme for the patient's teeth according to the target position and the current position for multiple periods.

In step 1003, when the computing device satisfies the multi-pressure step addition condition, adding the first correction step to the first tooth correction scheme to obtain a second tooth correction scheme.

Wherein a first appliance is used to maintain a current appliance position of the patient's teeth.

Specifically, the multi-step adding condition is determined in response to the adding operation of the first correction step after the client displays an operation interface for adding the first correction step in the first tooth correction scheme according to the operation of the client in response to the multi-step function.

In step 1004, the computing device creates an appliance corresponding to one or more of the appliance steps in the second dental appliance according to the second dental appliance.

In one embodiment, the method for manufacturing the dental appliance is selected according to different needs of patients, for example, if the patients are patients who cannot frequently go to hospital for review due to country reasons and the like, all dental appliances of the correction steps can be manufactured together according to a second dental correction scheme so as to avoid the situation that the patients cannot arrive at the site, or if the patients are patients who need to delay the dental correction stage due to operation and the like, only part of the dental appliances can be provided at a time according to the second dental correction scheme, and the rest of the dental appliances are allowed to be provided for the time of the patients. In this way, the method not only reduces the scheme determination and the manufacturing period of the dental appliance, but also provides humanized selection space for customers, and the dental appliance process of customers is more convenient.

In one embodiment, the SLA method is used to make a solid dental model, specifically, to make a solid dental model, a laser under computer control is used to scan the liquid resin point by point along each layered cross-sectional profile of the dental model based on the polymerization of the photosensitive resin, so that the scanned resin layers polymerize, the points gradually form lines, and a cured cross-section of one layer of the solid dental model is finally formed, while the resin which is not scanned remains in the original liquid state. When one layer is cured, the lifting workbench moves a layer thickness distance, and a new layer of liquid resin is covered on the surface of the cured resin layer for scanning and curing again. The newly cured layer is firmly bonded to the previous layer and the cycle is repeated until the entire solid dental model is manufactured. The part is then subjected to high intensity ultraviolet radiation to complete the curing process, resulting in a solid dental model, i.e., a positive or male model for the manufacture of the dental appliance.

Further, the method of making the dental appliance may include pressing an appliance film made of a transparent polymer material (a polymer having elasticity, such as polycarbonate) on the above-described solid dental model by a positive pressure lamination technique with a hot press forming apparatus to form a shell, thereby making the dental appliance, or the method of making the dental appliance may further include modeling and printing the invisible dental appliance with a digital dental model in a second dental appliance scheme with a 3D printing apparatus.
