Abstract
Description
Technical Field
[0001] The present application relates to the technical field of dental correction, and specifically to a method and device for invisible correction of stable jaw position relationship. Background Art
[0002] The principle of invisible braces mainly relies on applying continuous external force to the teeth to make them move, so as to achieve the purpose of neatly arranging the teeth and restoring the normal occlusal relationship. In the prior art, the teeth are fully wrapped by wearing invisible braces (such as polymer plastic elastic membranes), and the teeth are moved by the resilience of the plastic membrane, thereby achieving stable correction of the tooth-jaw relationship. Since the elasticity of the plastic membrane is limited, it is necessary to simulate the movement of the teeth through computer technology to achieve precise correction. General invisible braces need to be designed within a certain period of time to gradually and stably correct the tooth-jaw relationship until the tooth correction is completed. Invisible braces will not affect the beauty of the teeth during the correction period, and the effect is relatively natural.
[0003] The existing technology generally uses braces design software (for example, Nobel Procera or 3Shape Dental System, etc.) to scan and obtain the current jaw relationship of the teeth, and then design corrective braces based on the current jaw relationship of the teeth. It should be clear that the invisible correction process is carried out step by step, and the above method does not take into account the impact of historical corrective braces on the jaw relationship of the teeth. As a result, a large number of corrective braces are required in the invisible correction process. Since the production cost of corrective braces is relatively high, if a large number of corrective braces are used, the cost of the tooth correction process will be higher. Summary of the invention

[0058] 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. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0059] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings 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. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be understood that the spatial preset points used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that shown or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or modules is not necessarily limited to those steps or modules that are clearly listed, but may include other steps or modules that are not clearly listed or inherent to these processes, methods, products or devices. The division of modules that appear in the embodiments of the present application is only a logical division. There may be other division methods when implemented in actual applications.

In addition, the coupling or direct coupling or communication connection between each other shown or discussed can be through some interfaces, and the indirect coupling or communication connection between modules can be electrical or other similar forms, which are not limited in the embodiments of the present application.

[0061] Before understanding the embodiments of the present application, it should be clear that the braces design software establishes a correction braces model based on the user's jaw position relationship. Generally, the braces design software calculates the correction force value required to correct the teeth within a cycle based on the abnormal position of the teeth, and then generates a correction braces model based on each correction force value. The maker makes the correction braces based on the correction braces model, and after the user wears the correction braces, the jaw position relationship of the teeth can be corrected. It is easy to understand that in the process of the design software calculating the correction force value required to correct the teeth, the greater the degree of abnormality of the teeth, the greater the corresponding correction force value; if the degree of abnormality of the teeth is smaller, the corresponding correction force value is smaller. It should be clear that each correction brace hopes to correct the user's teeth to the corresponding position until the jaw position relationship of the user's teeth is normal. In other words, in the process of tooth correction, it is not desirable for the position of the teeth to move too fast or too slowly. That is, it is hoped that each tooth can be stably formed and moved. Since the strength of teeth of different users is different, and the strength of teeth of the same user is also different, the correction force value required for correction of teeth calculated based on the design software is not necessarily applicable to all teeth of the user. In other words, the correction force value required for correction of teeth calculated based on the design software is likely to cause the position of the user's teeth to move too fast or too slow. It is easy to understand that during the correction process, if each brace causes the teeth to move too fast or too slow, the number of corrections will definitely increase, that is, the number of correction braces used during the correction cycle will increase.
[0062] In order to solve the technical problem that a large number of braces are used in the prior art, resulting in high correction costs and a long correction period, the present application proposes an embodiment of a method for invisible correction of stabilizing jaw position relationship, such as Figure 1 As shown, the method includes steps S100 to S500.
[0063] Step S100: Acquire the current jaw position relationship data of the user's teeth.
[0064] In the human oral cavity, teeth grow in the alveolar sockets in a certain direction and order to form natural dentition (i.e., natural dentition of the upper and lower jaws), which constitute the basis of occlusion. The basic movement of chewing food is occlusal movement, that is, the mandible makes various types and forms of irregular and constantly changing movements relative to the upper jaw. Therefore, the occlusion and jaw, as well as the occlusion position and jaw position are formed. The occlusion is the contact between the upper and lower dentitions; the jaw refers to the position of the mandible relative to the maxilla; however, the occlusion refers to the contact relationship between the upper and lower dentitions and between the teeth; the jaw position refers to the position relationship between the mandible and the maxilla. Therefore, there are countless jaw positions, but the most stable ones in the process of orthodontic treatment are three jaw position relationships, namely, the cusp interdigitation position (central occlusion position), the retracted contact position (central relationship position), and the mandibular posture position (resting position). I will not go into too much detail about the specific jaw position relationship here.
[0065] In the embodiments of the present application, the current jaw relationship data of the user's teeth can be obtained in any manner. For example, common jaw relationship acquisition methods include the compression plate method, the static film method, the dynamic film method and the scanning method. The jaw relationship generally refers to the occlusal relationship between the upper and lower jaws, and determining the occlusal relationship is a relatively important task in stomatology. Among them, the compression plate method can determine the jaw relationship by placing a bite plate between the upper and lower jaws and asking the patient to bite. It is a relatively simple and easy determination method and usually does not require other special equipment. The static film method determines the jaw relationship by measuring the static distance between the upper and lower jaws of the patient. Special measuring tools such as face bows and film back gauges are usually used to reflect the static relationship between the upper and lower jaws. The dynamic film method can determine the jaw relationship by measuring the dynamic distance between the upper and lower jaws. Electronic face bows, electronic film thickness gauges, etc. are usually used for measurement, which can more accurately determine the jaw relationship. The scanning method is to obtain a digital model of the specific spatial position relationship between the upper and lower dentition or edentulous jaws through an intraoral scanner, and then determine the jaw relationship.
[0066] That is to say, in the embodiment of the present application, any of the above methods can be used to obtain the current jaw position relationship data of the user's teeth. Since the above methods are mature technologies, they will not be described in detail here.
[0067] Step S200: Based on the current jaw position relationship data, data abnormality features are acquired.
[0068] It should be clear that, as can be seen from the foregoing, in the embodiments of the present application, the data anomaly feature is mainly used to reflect the change in the position of the teeth before and after the teeth are corrected using a correction brace. Ideally, the position of the teeth after correction should be the same as the preset correction position of the teeth. Therefore, in the embodiments of the present application, the data anomaly feature at least includes characteristic data for characterizing the degree of change in the position of the user's teeth.
[0069] It is easy to understand that in the embodiments of the present application, if the position of the tooth after correction is relatively small relative to the preset correction position of the tooth, then in the subsequent correction process, the correction force value on the tooth needs to be increased; if the position of the tooth after correction is relatively large relative to the preset correction position of the tooth, then in the subsequent correction process, the correction force value on the tooth needs to be reduced.
[0070] In an embodiment of the present application, data abnormality features may be obtained in any manner based on the current jaw position relationship data. For example, in an embodiment of the present application, step S200, based on the current jaw position relationship data, obtaining data abnormality features includes steps S210 to S240.
[0071] Step S210: Acquire the target tooth.
[0072] It should be clear that after each tooth correction using braces, it is necessary to confirm whether each tooth of the user is corrected to a preset correction position (i.e., an ideal correction position) by the braces. Since the position of each tooth of the user needs to be confirmed, the target tooth is any tooth of the user that does not have abnormal data features.
[0073] Step S220: Based on the target tooth, obtain the current position of the target tooth.
[0074] As can be seen from the foregoing, the current position of the target tooth, that is, the position of the tooth after correction by the orthodontic braces, can be obtained by any one of the following methods, namely, the lamination method, the static film method, the dynamic film method and the scanning method, or a combination of these methods, which will not be described in detail here.
[0075] Step S230: Based on the target tooth, a preset correction position of the target tooth is obtained.
[0076] In the embodiments of the present application, the preset correction position of the target tooth is the ideal correction position of the target tooth. In other words, the preset correction position of the target tooth is a position known before the correction brace is made, that is, the preset correction position of the target tooth is a fixed position known in advance, and no further details are given here.
[0077] Step S240: Based on the current position of the target tooth and the preset correction position, obtain data abnormality features of the target tooth.
[0078] During the tooth correction process, it is difficult for most teeth to be 100% corrected to the ideal correction position (i.e., the preset correction position). As can be seen from the foregoing, the data abnormality characteristics of the target teeth at least include characteristic data for characterizing the degree of change in the position of the user's teeth. In other words, the data abnormality characteristics of the target teeth at least include data for characterizing the difference between the current position of the user's target teeth and the preset correction position.
[0079] In an embodiment of the present application, data of any difference between the current position of the target tooth of the user and the preset correction position can be used as the data abnormality feature of the target tooth. For example, in one embodiment of the present application, step S240, based on the current position of the target tooth and the preset correction position, obtaining the data abnormality feature of the target tooth includes steps S241 to S243.
[0080] Step S241: Based on the current position of the target tooth, a first spatial preset point is acquired.
[0081] like Figure 2 As shown, assuming Figure 2 The tooth represented by the solid line is the current position of the target tooth, and the first spatial preset point can be the center of gravity or the center of mass of the tooth represented by the solid line. Figure 2 The tooth represented by the solid line is the projection of the current position of the target tooth on the paper (the projection direction is perpendicular to the axis of the target tooth and also perpendicular to the moving direction of the target tooth, that is, Figure 2 In the direction A), the first spatial preset point can also be the center point, center of mass, center of gravity, circumscribed circle center point or inscribed circle center point of the above-mentioned projection.
[0082] Step S242: Based on the preset correction position of the target tooth, a second spatial preset point is obtained.
[0083] like Figure 2 As shown, assuming Figure 2 The tooth represented by the middle dotted line is the preset correction position of the target tooth. The second spatial preset point is a point corresponding to the first spatial preset point mentioned above.
[0084] Step S243: Based on the first spatial preset point and the second spatial preset point, the data abnormality feature of the target tooth is obtained.
[0085] In an embodiment of the present application, the data abnormality feature of the target tooth may be the distance between the first spatial preset point and the second spatial preset point. It is easy to understand that, in an ideal state, if the first spatial preset point and the second spatial preset point coincide with each other (that is, the distance between the first spatial preset point and the second spatial preset point is 0), then the current position of the target tooth coincides with the preset correction position. In other words, the greater the distance between the first spatial preset point and the second spatial preset point, the greater the degree of change in the position of the target tooth before and after correction, that is, the more the correction force value for the target tooth needs to be adjusted.
[0086] In another embodiment of the present application, step S240, based on the current position and the preset correction position of the target tooth, obtaining the data abnormality characteristics of the target tooth includes steps S244 to S246.
[0087] Step S244: Based on the current position of the target tooth, obtain a first projection of the target tooth along a first direction.
[0088] In the embodiments of the present application, the first direction may be any direction. For example, the first direction may be perpendicular to the axis of the target tooth. Figure 3 As shown, the first direction is parallel to the axis of the target tooth. It should be clear that the corresponding projection of the target tooth can be obtained by determining the projection direction, which will not be described in detail here. In the embodiment of the present application, the projection of the current position of the target tooth along the first direction is as follows: Figure 3 As shown in the solid line area, direction A represents the movement direction of the target tooth.
[0089] Step S245: Based on the preset correction position of the target tooth, obtain a second projection of the target tooth along the first direction.
[0090] In an embodiment of the present application, based on the second projection obtained along the first direction of the preset correction position of the target tooth, Figure 3 The dotted area is shown in .
[0091] Step S246: Based on the first projection and the second projection, obtain data abnormality features of the target tooth.
[0092] It is easy to understand that, in an ideal state, if the first projection and the second projection coincide, the current position of the target tooth coincides with the preset correction position. In other words, if the coincidence between the first projection and the second projection is smaller, the position change of the target tooth before and after correction is greater, that is, the correction force value for the target tooth needs to be adjusted more.
[0093] like Figure 3 As shown, the overlapping area formed by the first projection and the second projection is shown as the shaded area. In the embodiment of the present application, the ratio of the area at the shaded area to the area of the first projection or the second projection can be used as a data anomaly feature. It is easy to understand that, ideally, the ratio of the area at the shaded area to the area of the first projection is equal to 1.
[0094] Step S300: Based on the current jaw position data, an initial correction force value is obtained.
[0095] It should be clear that obtaining the initial correction force value based on the current jaw position data with the help of braces design software is a mature technology and will not be elaborated on here.
[0096] Step S400: adjusting the initial correction force value based on the data abnormality feature to obtain an adjusted correction force value.
[0097] It should be clear that in the embodiments of the present application, the initial correction force value can be adjusted in any manner. Figure 2 As shown in FIG. 1 , along the moving direction of the target tooth (ie, direction A), the current position of the target tooth has not reached the preset correction position, so the initial correction force value of the target tooth needs to be increased. Figure 3 As shown, along the moving direction of the target tooth (ie, direction A), the current position of the target tooth exceeds the preset correction position, so the initial correction force value of the target tooth needs to be reduced.
[0098] In the embodiments of the present application, the degree of increasing or decreasing the initial correction force value can be adjusted according to empirical values, or can be adjusted according to experimental values obtained from multiple tests.
[0099] As can be seen from the foregoing, in the process of tooth correction, it is difficult for most teeth to be 100% corrected to the ideal correction position (that is, the preset correction position). If the difference between the current position of the target tooth and the preset correction position is small, it can be assumed that the initial correction force value is compatible with the target tooth, and there is no need to adjust the initial correction force value. Therefore, in a specific embodiment of the present application, step S400 adjusts the initial correction force value based on the abnormal data characteristics, and obtaining the adjusted correction force value includes step S410 and step S420.
[0100] Step S410: If the characteristic data of the degree of change in the position of the user's teeth is less than or equal to a first preset threshold, the adjusted correction force value is equal to the initial correction force value.
[0101] It should be understood that, in the embodiments of the present application, the first preset threshold may be an empirical value or an experimental value obtained through multiple experiments.
[0102] Step S420: If the characteristic data of the degree of change in the position of the user's teeth is greater than a first preset threshold, the adjusted correction force value is equal to the initial correction force value multiplied by an adjustment coefficient.
[0103] That is to say, in this embodiment, the initial correction force value is adjusted only when the difference between the current position of the target tooth and the preset correction position reaches a certain degree.
[0104] In the embodiments of the present application, the adjustment coefficient can be any suitable value, for example, the adjustment coefficient can be a fixed value. Relative to the preset correction position of the tooth, if the position of the tooth after correction is relatively small, the adjusted correction force value can be equal to 1.2 (that is, the adjustment coefficient) times the initial correction force value; relative to the preset correction position of the tooth, if the position of the tooth after correction is relatively large, the adjusted correction force value can be equal to 0.8 (that is, the adjustment coefficient) times the initial correction force value. Of course, in other embodiments of the present application, the fixed value adjustment coefficient can also be set according to experience.
[0105] In order to make the adjustment coefficient adapt to the situation of the teeth after adjustment, in one embodiment of the present application, the calculation formula of the adjustment coefficient is as follows:
[0106] Z = 1 + linspace(x);
[0107] Wherein, Z represents the adjustment coefficient; x represents the characteristic data of the degree of change in the user's tooth position; linspace represents the linspace function that maps the data to the interval (-1, 1). It should be understood that in the embodiment of the present application, if the current position of the target tooth has not reached the preset correction position, x is a positive value; if the current position of the target tooth exceeds the preset correction position, x is a negative value.
[0108] Step S500: obtaining a correction brace model based on the adjusted correction force value.
[0109] It should be clear that the invisible braces method for stabilizing the jaw relationship proposed in the embodiment of the present application can adjust the initial correction force value of subsequent braces based on the impact of historical correction braces on the jaw relationship of teeth, so that the correction force generated by subsequent correction braces can be more adapted to the user's teeth. Since the correction braces can adapt to the user's teeth, the number of correction braces used can be reduced during the correction cycle. If the number of correction braces used during the correction cycle is small, it can reduce the cost of tooth correction and shorten the time of tooth correction.
[0110] After introducing the embodiment of the method for invisible correction of stabilizing jaw position relationship proposed in the present application, the following introduces an embodiment of a device for invisible correction of stabilizing jaw position relationship proposed in the present application, such as Figure 4 As shown, the invisible orthodontic device 10 for stabilizing jaw position relationship comprises:

[0124] and, based on the preset correction position of the target tooth, acquiring a second projection of the target tooth along a first direction;
[0125] And, based on the first projection and the second projection, data abnormality features of the target tooth are acquired.
[0126] As a specific embodiment of the present application, the processing module 12 is further configured to, if the characteristic data of the degree of change in the position of the user's teeth is less than or equal to a first preset threshold value, the adjusted correction force value is equal to the initial correction force value;
[0127] If the characteristic data of the degree of change in the position of the user's teeth is greater than a first preset threshold, the adjusted correction force value is equal to the initial correction force value multiplied by an adjustment coefficient.
[0128] As a specific embodiment of the present application, the processing module 12 is further used to calculate the adjustment coefficient using the following formula:
[0129] Z = 1 + linspace(x);
[0130] Wherein, Z represents the adjustment coefficient; x represents the characteristic data of the degree of change in the user's tooth position; and linspace represents the linspace function that maps the data to the interval (-1, 1).
[0131] It should be clear that the invisible braces for stabilizing the jaw relationship proposed in the embodiment of the present application can adjust the initial correction force value of subsequent braces based on the impact of historical correction braces on the jaw relationship of teeth, so that the correction force generated by subsequent correction braces can be more adapted to the user's teeth. Since the correction braces can adapt to the user's teeth, the number of correction braces used can be reduced during the correction cycle. If the number of correction braces used during the correction cycle is small, it can reduce the cost of tooth correction and shorten the time of tooth correction.
