Description

Method and device for generating digital model of orthodontic appliance and method for manufacturing orthodontic appliance

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on October 31, 2023, with application number 2023114365950 and invention name “Method, device and method for manufacturing a digital model of an orthodontic appliance”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of orthodontic appliances, and specifically to a method for generating a digital model of an orthodontic appliance with an anti-caries function. The present application also relates to a device for generating a digital model of an orthodontic appliance with an anti-caries function, an electronic device, a computer storage medium, a method for manufacturing an orthodontic appliance, a device for manufacturing an orthodontic appliance, an orthodontic appliance, and a method for manufacturing an orthodontic appliance mold. Background Art

[0003] Silicone braces are widely used in the treatment of malocclusion in children. They have good effects in correcting bad oral habits, inducing tooth eruption and establishing normal occlusion.

[0004] In the relevant technology, silicone braces are divided into two categories: prefabricated and personalized. Prefabricated silicone braces are a type of mass-produced product. The product series of prefabricated silicone braces are divided into multiple sizes and models. In clinical applications, relatively suitable models are selected according to the patient's oral condition. Personalized silicone braces are produced by collecting the patient's dental and maxillofacial data, combining the patient's specific situation, and manually customizing the mold to produce personalized silicone braces. Compared with prefabricated silicone braces, personalized silicone braces are more in line with the patient's dental and maxillofacial characteristics and have better applicability and comfort.

[0005] However, regardless of whether the appliance is prefabricated or custom-made, the presence of fixed appliances significantly increases the number of cariogenic bacteria, and salivary flow rate and buffering capacity also change. When removable appliances are used, the number of decayed, missing, and filled teeth increases significantly (with more severe caries) and lingual plaque accumulation increases.

[0006] Therefore, how to quickly and accurately manufacture orthodontic appliances that meet the needs of patients has become an urgent problem to be solved by those skilled in the art.

[0124] The following description sets forth many specific details to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the scope of the present application. Therefore, the present application is not limited to the specific implementations disclosed below.

[0125] Silicone braces are widely used in the treatment of malocclusion in children. They have good effects in correcting bad oral habits, inducing tooth eruption and establishing normal occlusion.

[0126] In the relevant technology, silicone braces are divided into two categories: prefabricated and personalized. Prefabricated silicone braces are a type of mass-produced product. The product series of prefabricated silicone braces are divided into multiple sizes and models. In clinical applications, relatively suitable models are selected according to the patient's oral condition. Personalized silicone braces are produced by collecting the patient's dental and maxillofacial data, combining the patient's specific situation, and manually customizing the mold to produce personalized silicone braces. Compared with prefabricated silicone braces, personalized silicone braces are more in line with the patient's dental and maxillofacial characteristics and have better applicability and comfort.

[0127] However, regardless of whether the appliance is prefabricated or custom-made, the presence of fixed appliances significantly increases the number of cariogenic bacteria, and salivary flow rate and buffering capacity also change. When removable appliances are used, the number of decayed, missing, and filled teeth increases significantly (with more severe caries) and lingual plaque accumulation increases.

[0128] Therefore, the embodiments of the present application provide a method for generating a digital model of an orthodontic appliance with an anti-caries function to solve the problem of how to quickly and accurately manufacture an orthodontic appliance that meets the needs of patients in the prior art. The embodiments of the present application also provide a device for generating a digital model of an orthodontic appliance with an anti-caries function, an electronic device, a computer storage medium, a method for manufacturing an orthodontic appliance, a manufacturing device for an orthodontic appliance, an orthodontic appliance, and a method for making an orthodontic appliance mold.

[0129] The present application is described in detail below through multiple embodiments and drawings.

[0130] First embodiment

[0131] The first embodiment of the present application provides a method for generating a digital model of an orthodontic appliance with an anti-caries function. The method for generating a digital model of an orthodontic appliance with an anti-caries function is described in detail below with reference to FIG1 . FIG1 is a schematic flow chart of the method for generating a digital model of an orthodontic appliance with an anti-caries function provided in the first embodiment of the present application. The method comprises the following steps:

[0132] Step S101: Obtaining a morphological information sample for generating a digital model of an orthodontic appliance.

[0133] In this step, the morphological information sample describes the morphological features of the appliance, and the digital model of the appliance is used to control the appliance manufacturing device to manufacture the appliance.

[0134] In this step, obtaining a morphological information sample for generating a digital model of the orthodontic appliance specifically includes the following steps: first, obtaining oral parameters. In one example, the oral parameters include at least tooth morphology parameters, occlusal relationship parameters, molar relationship parameters, and oral soft tissue parameters. The oral parameters can be obtained by: obtaining them through an intraoral scanner or a patient's dental impression; obtaining them through an intraoral scanner or a jaw frame; or obtaining them through optical scanning technology, X-ray imaging technology, ultrasonic imaging technology, computed tomography (CT) scanning, or magnetic resonance imaging technology.

[0135] After obtaining the oral cavity parameters, the overall morphological information sample and the alveolar morphological information sample for generating the digital model of the orthodontic appliance are obtained based on the oral cavity parameters. That is, generating the morphological information sample for the digital model of the orthodontic appliance includes generating the overall morphological information sample and the alveolar morphological information sample for generating the digital model of the orthodontic appliance. The specific steps for obtaining the overall morphological information sample and the alveolar morphological information sample for generating the digital model of the orthodontic appliance based on the oral cavity parameters are described below.

[0136] Specifically, in this embodiment, obtaining overall morphological information samples for generating a digital model of an orthodontic appliance based on oral parameters includes obtaining length and width information samples of the upper and lower dentition based on the oral parameters. In one example, the width information samples of each upper and lower dentition can be calculated and fitted using the incisor width, intercanine width, and intermolar width. While obtaining the incisor width, intercanine width, and intermolar width, corresponding positional information of the incisor, canine, and molar can be obtained. Length information samples of the upper and lower dentition are then obtained based on the incisor width, intercanine width, and intermolar width, and their corresponding positional information. Next, based on the length and width information samples of the upper and lower dentition, occlusal spacing samples are obtained between the upper and lower dentitions. The occlusal spacing samples can be used to determine the degree of mandibular opening. Finally, based on the length and width information samples of the upper and lower dentitions, as well as the occlusal spacing samples between the upper and lower dentitions, an overall morphological information sample for generating a digital model of the orthodontic appliance is obtained.

[0137] In this embodiment, alveolar morphological information samples for generating a digital model of an orthodontic appliance are obtained based on oral parameters, including: morphological samples of the labial and buccal contours and lingual contours of the upper and lower dentitions, and gingival position samples of each tooth in the upper and lower dentitions are obtained based on oral parameters. Then, the morphological samples of the labial and buccal contours and lingual contours, and the gingival position samples of each tooth are smoothed to determine the processed standard morphological samples. For example, the outer wall length of the digital model of the orthodontic appliance is fitted and adjusted based on the smoothed gingival position line between two teeth in different dentition areas (such as incisors, canines, molars, etc.). The outer wall length can satisfy the requirement that the orthodontic appliance does not press on the gums, such as if the outer wall length of the orthodontic appliance does not reach the gum position. Then, based on the standard morphological samples, alveolar morphological information samples for generating a digital model of an orthodontic appliance are obtained.

[0138] After obtaining the overall morphological information sample and the alveolar morphological information sample, a morphological information sample for generating a digital model of the orthodontic appliance is obtained based on the overall morphological information sample and the alveolar morphological information sample.

[0139] Step S102: obtaining a silica gel component sample corresponding to the morphological information sample.

[0140] After obtaining a morphological information sample used to generate a digital model of the orthodontic appliance, a silicone component sample corresponding to the morphological information sample is obtained. In this embodiment, the silicone component sample includes at least a fluoride component sample, which includes sample data obtained from fluoride adsorbed in the silicone and released onto the tooth surface through the silicone. The silicone component sample also includes sample data obtained from the silicone. In this embodiment, since the silicone component sample includes at least the fluoride component sample, it is necessary to determine the component ratio information of the fluoride component sample in the orthodontic appliance in order to obtain the silicone component sample corresponding to the morphological information sample.

[0141] Specifically, in one example, obtaining a silicone component sample for the morphological information sample includes obtaining component ratio information of the fluoride component sample in the appliance, and determining a silicone component sample for the morphological information sample based on the component ratio information. In this example, the appliance comprises only fluoride and silicone. By clarifying the fluoride component ratio, the silicone component ratio is also indirectly determined. Thus, after obtaining the morphological information sample used to generate a digital model of the appliance, a silicone component sample for the morphological information sample can be determined based on the component ratio information of the morphological information sample.

[0142] In another example, it also includes: obtaining a dental health information sample about the teeth, the dental health information includes whether the teeth have caries and information about the causes of caries, wherein the information about the causes of caries includes information such as bacterial causes, oral environment, parasites and time, and can be specific to which position of a tooth or which tooth has a dental health problem. After obtaining the dental health information sample about the teeth, a medical information sample for the teeth can be obtained based on the dental health information sample, and the opinion information is used to treat the teeth with health problems. Finally, a silicone component sample for the morphological information sample is obtained based on the dental health information sample and the medical information sample. Specifically, the morphological information sample describes the morphological characteristics of the orthodontic appliance, that is, what specific form the orthodontic appliance corresponding to the tooth has. After determining the morphological information sample of the orthodontic appliance for the tooth to be corrected, the silicone component sample can be specifically set in combination with the obtained dental health information sample and the medical information sample, and specifically how to set fluoride in the form of the orthodontic appliance. In one example, it is determined that a tooth in the lower dentition has a caries problem. Accordingly, a medical information sample is obtained for the caries problem of the tooth. The medical information includes the installation of fluoride at the position of the orthodontic appliance corresponding to the tooth, so that a corresponding proportion of fluoride is added to the silicone component sample of the training morphological information sample.

[0143] In another example, the silicone component sample also includes a first type of glue component sample and a second type of glue component sample, wherein the first type of glue component sample includes sample data obtained from component A glue, and the second type of glue component sample includes sample data obtained from component B glue; the component A glue corresponding to the first type of glue component sample and the component B glue corresponding to the second type of glue component sample react with each other to generate silicone with a microporous structure inside, the component A glue and the component B glue do not react with the fluoride component sample, the fluoride component sample is adsorbed in the microporous structure of the silicone, and fluoride is released to the tooth surface through the micropores. In this embodiment, the average diameter of micropores of different diameters is obtained by adjusting the conditions during the preparation process, wherein the adjustment of the conditions during the preparation process includes: adjusting the diameter of the micropores in the orthodontic appliance by adjusting the pressure during injection molding during the preparation process.

[0144] In practice, the ratio of the fluoride is determined based on product specifications. After the component A glue, component B glue, and fluoride are evenly mixed, the mixed material is injected into the mold using a glue injection machine. During the injection process, the silicone rubber is constantly inspected for impurities or bubbles, and any impurities or bubbles present are expelled. After the glue injection machine completes the injection, a pressurizing device applies varying pressures to the mixed material in the mold and maintains these pressures until the silicone product in the mold is dried and shaped. This ensures that the silicone orthodontic appliance produced through this process has varying pore diameters.

[0145] It should be noted that the release rate of fluoride in the brace is directly related to the micropore diameter. Therefore, in the process of preparing the brace, the pressure applied by the pressure-applying device in the injection molding step can be adjusted to adjust the micropore diameter of the silicone brace. According to experiments, the release rate of fluoride in the brace is not only related to the internal micropore diameter of the silicone, but also to the content ratio of the fluoride in the brace. The higher the content ratio of the fluoride, the faster the release rate of the fluoride, and the lower the content ratio, the slower the release rate of the fluoride. Moreover, because the fluoride in the brace is in a solid form and filled in the microporous structure of the silicone. Therefore, after the user wears the brace, the fluoride will continue to be released, causing the fluoride content in the brace to slowly decrease. Therefore, the release rate of fluoride in the brace will gradually decrease.

[0146] Based on the above situation, it can be seen that according to the dental condition of each user, an orthodontic appliance with a different release rate needs to be matched for the user. The release rate of fluoride in the orthodontic appliance can be adjusted in the following three ways.

[0147] (1) When the micropore diameter is constant, the release ratio of the fluoride in the orthodontic appliance is adjusted by adjusting the predetermined ratio of the fluoride material, so that the orthodontic appliance has different release rates during the treatment period.

[0148] (2) When the predetermined ratio of the selected fluoride is constant, the release rate of the fluoride in the orthodontic appliance is adjusted by adjusting the diameter of the micropores, so that the orthodontic appliance has different release rates during treatment.

[0149] (3) Simultaneously adjusting the micropore diameter and the predetermined ratio of the fluoride material to adjust the release rate of the fluoride in the orthodontic appliance during the treatment period.

[0150] In this embodiment, the fluoride includes a fluorine-containing organic or inorganic compound, for example, but not limited to one or more of the following molecules: sodium fluoride, sodium monofluorophosphate, stannous fluoride, fluorosilicic acid, sodium fluorosilicate, fluorophosphate, fluorosilane, etc.

[0151] In this embodiment, the ratio of component A glue and component B glue is determined according to preset requirements. Specifically, in the process of preparing the braces with anti-caries function, the content of fluoride in the predetermined ratio is determined according to the wearer's dental condition. Specifically, according to the diagnosis results of the wearer's teeth, the proportion of fluoride in the braces is adjusted. For example, the fluoride content is in the following range: 0.01% ≤ fluoride ≤ 15%; the component A glue and the component B glue account for the remaining proportion. Optionally, the component A glue and the component B glue respectively include the following combination methods: the ratio of component A glue to component B glue is equal to 1:1 or other ratios.

[0152] Correspondingly, obtaining a silicone component sample for the morphological information sample includes: obtaining the component ratio information of the fluoride component sample, the first type of glue component sample and the second type of glue component sample constituting the orthodontic appliance, and determining the silicone component sample for the morphological information sample based on the component ratio information. In this example, the components constituting the orthodontic appliance include fluoride, the first type of glue and the second type of glue, and the component ratio of each component is clarified. Therefore, after obtaining the morphological information sample for generating the digital model of the orthodontic appliance, the silicone component sample for the morphological information sample can be determined according to the component ratio information based on the morphological information sample. For example, the first type of glue, the second type of glue and the fluoride are mixed evenly to form a mixture. In this step, under the premise that the first type of glue and the second type of glue can fully react, the fluoride is evenly distributed inside the mixture. The specific mixing process is as follows: stirring with a glue mixing stick and placing it in a glue mixing device. Set the stirring parameters and start the glue mixing device. After the glue mixing is completed, place it in a mixing container. After manual stirring, pour the mixed silicone into the glue injection device. The glue injection device forms a silicone component sample for the morphological information sample according to the component ratio information.

[0153] In another example, the silicone component sample also includes a third type of glue component sample, and the third type of glue component sample includes a dye. Correspondingly, obtaining a silicone component sample for the morphological information sample includes: obtaining the component ratio information of the fluoride component sample, the first type of glue component sample, the second type of glue component sample, and the third type of glue component sample constituting the orthodontic appliance, and determining the silicone component sample for the morphological information sample based on the component ratio information. In this example, the components constituting the orthodontic appliance include fluoride, the first type of glue, the second type of glue, and the third type of glue component samples, and the component ratio of each component is clarified. Therefore, after obtaining the morphological information sample used to generate the digital model of the orthodontic appliance, the silicone component sample for the morphological information sample can be determined according to the component ratio information based on the morphological information sample.

[0154] In each of the above examples, the proportion of fluoride component samples is in the following range: 0.01% ≤ fluoride ≤ 15%.

[0155] In each of the above examples, the fluoride and the various components are uniformly mixed together to form a mixture, which is then injection molded into a silicone component sample corresponding to the morphological information sample. The following embodiments distinguish the positions of the various components in the injection molded appliance, as follows:

[0156] In one example, the silicone component sample includes fluoride, and also includes a first type of glue component sample and a second type of glue component sample, wherein the first type of glue component sample and the second type of glue component sample react with each other to generate a silicone with a microporous structure inside, and the first type of glue component sample and the second type of glue component sample do not react with the fluoride component sample. Correspondingly, obtaining the silicone component sample for the morphological information sample includes: first, obtaining the component ratio information of the fluoride component sample, the first type of glue component sample and the second type of glue component sample constituting the orthodontic device, in this example, the components constituting the orthodontic device include fluoride, the first type of glue and the second type of glue, and clarifying the component ratio of each component substance. Then, obtaining the designated area information samples of the fluoride component sample, the first type of glue component sample and the second type of glue component sample in the morphological information sample. In this example, the first type of glue and the second type of glue react to form a mixture. Finally, a silicone component sample for the morphological information sample is determined based on the component ratio information and the designated area information sample. Specifically, the designated area information sample in the morphological information sample is divided into a first area information sample, a second area information sample, and a third area information sample that are adjacent in sequence. The first type of separated silicone component sample and the second type of separated silicone component sample are fused and set in the first area information sample and the second area information sample, and the fluoride component sample is set in the third area information sample. Alternatively, the first type of separated silicone component sample and the second type of separated silicone component sample are fused and set in the first area information sample and the third area information sample, and the fluoride component sample is set in the second area information sample. Alternatively, the first type of separated silicone component sample, the second type of separated silicone component sample, and the fluoride component sample are fused and set in the first area information sample and the second area information sample. Alternatively, the first type of separated silicone component sample, the second type of separated silicone component sample, and the fluoride component sample are fused and set in the first area information sample and the third area information sample. Alternatively, the first type of separated silicone component sample, the second type of separated silicone component sample, and the fluoride component sample are fused and set in the second area information sample and the third area information sample.

[0157] In addition, in one example, considering that there is a third type of glue component sample, the first type of glue component sample, the second type of glue component sample, the third type of glue component sample, and the fluoride component sample can be fused and set as the first area information sample and the second area information sample. Alternatively, the first type of glue component sample, the second type of glue component sample, the third type of glue component sample, and the fluoride component sample can be fused and set as the first area information sample and the third area information sample. Alternatively, the first type of glue component sample, the second type of glue component sample, the third type of glue component sample, and the fluoride component sample can be fused and set as the second area information sample and the third area information sample.

[0158] In one example, the area proportion information of the first area information sample, the second area information sample, and the third area information sample is the same area proportion information. The area proportion information is relative to the overall shape of the appliance. For example, the area proportion information of the first area information sample, the second area information sample, and the third area information sample is 1:1:1, that is, the first area, the second area, and the third area divide the entire appliance into three equally divided areas. In another example, the area proportion information of the first area information sample, the second area information sample, and the third area information sample is different area proportion information. For example, the area proportion information of the first area information sample, the second area information sample, and the third area information sample is 1:2:3, that is, the first area, the second area, and the third area divide the entire appliance into three unequal areas.

[0159] In one example, the first type of glue component samples includes sample data obtained from component A glue, and the second type of glue component samples includes sample data obtained from component B glue; the component A glue corresponding to the first type of glue component samples and the component B glue corresponding to the second type of glue component samples react with each other to generate silicone rubber with a microporous structure inside, and the component A glue and the component B glue do not react with the fluoride.

[0160] Step S103: generating a digital model of the appliance according to the morphological information sample and the silicone component sample.

[0161] After obtaining the morphological information sample and the silicone component sample, the digital model of the orthodontic appliance is generated according to the morphological information sample and the silicone component sample.

[0162] Specifically, first, an initial digital model of the orthodontic appliance is set up and the initial parameters are adjusted. Then, different morphological information samples and silicone composition samples are divided into a training sample group and a test sample group. The morphological information samples and silicone composition samples in the training sample group are standardized and normalized to ensure that different attributes have the same scale and unified representation, facilitating subsequent model training and comparison. After the morphological information samples and silicone composition samples are extracted and processed, a machine learning algorithm can be used to build the digital model of the orthodontic appliance. Common methods include decision trees, support vector machines, random forests, and deep learning. The appropriate algorithm depends on the size of the dataset, the type of features, and the performance requirements. Specifically, the morphological information samples and silicone composition samples in the training sample group are input into the initial digital model of the orthodontic appliance. Iterative training is performed. After a certain number of training cycles, the initial digital model is verified using morphological information samples and silicone composition samples in the test sample group. If the output meets the preset standard, the digital model of the orthodontic appliance is generated. If the output does not meet the preset standard, iterative training is continued until the output meets the preset standard, and the digital model of the orthodontic appliance is generated.

[0163] In one example, it also includes obtaining a dental health information sample about the teeth, and the dental health information includes whether the teeth have caries and information about the causes of caries, wherein the information about the causes of caries includes information such as bacterial causes, oral environment, parasites and time, and can be specific to which position of a tooth or which tooth has a dental health problem. After obtaining the dental health information sample about the teeth, a medical information sample for the teeth can be obtained based on the dental health information sample, and the opinion information is used to treat the teeth with health problems. Then, based on the dental health information sample and the medical information sample, an elastic strength sample for generating a digital model of the orthodontic appliance is obtained. In one example, the elastic strength can include multiple levels, such as successively increasing strength levels, primary elastic strength, secondary elastic strength, tertiary elastic strength, etc. Finally, a digital model of the orthodontic appliance is generated based on the morphological information sample, the silicone component sample and the elastic strength sample.

[0164] Specifically, the morphological information sample is divided into a plurality of target area samples. In one example, the morphological information sample is divided into a plurality of target area samples including a first target area sample, a second target area sample, and a third target area sample that are adjacent in sequence. Then, a regional elasticity strength sample is obtained for each target area. In one example, the regional elasticity strength sample corresponding to the first target area sample is a first-level elasticity strength, the regional elasticity strength sample corresponding to the second target area sample is a second-level elasticity strength, and the regional elasticity strength sample corresponding to the third target area sample is a third-level elasticity strength. In another example, the regional elasticity strength sample corresponding to the first target area sample is a first-level elasticity strength, the regional elasticity strength sample corresponding to the second target area sample is a second-level elasticity strength, and the regional elasticity strength sample corresponding to the third target area sample is a first-level elasticity strength.

[0165] At the same time, obtain regional silicone component samples for each target area. Specifically, after the first type of glue component sample and the second type of glue component sample are fused, they are set to the first target area sample with a first-level elastic strength and the second target area sample with a second-level elastic strength, and the fluoride component sample is set to the third target area sample with a third-level elastic strength. Alternatively, after the first type of glue component sample and the second type of glue component sample are fused, they are set to the first target area sample with a first-level elastic strength and the second target area sample with a second-level elastic strength, and the fluoride component sample is set to the third target area sample with a third-level elastic strength. Alternatively, after the first type of glue component sample, the second type of glue component sample and the fluoride component sample are fused, they are set to the first target area sample with a first-level elastic strength and the second target area sample with a second-level elastic strength. Alternatively, after the first type of glue component sample, the second type of glue component sample and the fluoride component sample are fused, they are set to the first target area sample with a first-level elastic strength and the third target area sample with a third-level elastic strength. Alternatively, the first type of adhesive component sample, the second type of adhesive component sample, and the fluoride component sample are combined and set to a second target area sample with a second level of elastic strength and a third target area sample with a third level of elastic strength. This ensures that the overall structural strength of the orthodontic appliance does not change or decrease due to the presence of fluoride.

[0166] It should be noted that the fluoride components in the samples of each target area can be set according to needs.

[0167] Finally, a digital model of the orthodontic appliance was generated based on the regional elastic strength samples and the regional silicone composition samples.

[0168] The first embodiment of the present application provides a method for generating a digital model of an orthodontic appliance with an anti-caries function. The method comprises obtaining a morphological information sample for generating the digital model of the orthodontic appliance and a silicone component sample for the morphological information sample, wherein the silicone component sample at least includes a fluoride component sample. Fluoride is adsorbed in the silicone and released to the tooth surface through the silicone. The digital model of the orthodontic appliance is generated based on the morphological information sample and the silicone component sample. The orthodontic appliance generated by the digital model of the orthodontic appliance is more suitable for the patient and meets the patient's personalized needs. In addition, by providing fluoride in the silicone component sample, the orthodontic appliance can be accurately and efficiently designed, and the fluoride can also be released to the tooth surface through saliva in the mouth to achieve the effect of preventing dental caries.

[0180] Fifth embodiment

[0181] In the above-mentioned first embodiment, a digital model method for an orthodontic appliance with an anti-caries function is provided. Correspondingly, the fifth embodiment of the present application provides a method for manufacturing an orthodontic appliance. The parts of this embodiment that are the same as those in the first embodiment will not be repeated here. Please refer to the corresponding parts in the first embodiment.

[0182] Please refer to Figure 4, which is a flow chart of a method for manufacturing an orthodontic appliance provided in a fifth embodiment of the present application. This method is based on the digital model of the orthodontic appliance generated by the method for generating a digital model of the orthodontic appliance with anti-caries function described in the first embodiment above. The digital model of the orthodontic appliance is used to obtain the morphological information and material composition of the orthodontic appliance based on the input information used to manufacture the orthodontic appliance; and the orthodontic appliance is manufactured using a 3D printing device or mold. The method includes the following steps:

[0183] Step S401: Obtain input information of the orthodontic appliance to be manufactured.

[0184] This input information can be set based on the patient's actual orthodontic needs. It primarily includes information about the tooth morphology and the silicone composition. The silicone composition includes at least fluoride, which is absorbed into the silicone and released onto the tooth surface through the silicone. The morphological information describes the morphological characteristics of the appliance.

[0185] Step S402: sending control instructions to the 3D printing device according to the input information.

[0186] After obtaining the input information of the orthodontic appliance to be manufactured, control instructions are sent to the 3D printing device based on the input information. In this step, the input information needs to be processed to convert it into instruction information that can be executed by the 3D printing device.

[0187] Step S403: Controlling the 3D printing device according to the control instruction to produce material components for forming the appliance according to the morphological information of the appliance to be manufactured and forming the appliance; or using the mold according to the control instruction to manufacture the appliance according to the morphological information of the appliance to be manufactured; wherein the material components include a silicone component and a fluoride component, and the fluoride is adsorbed in the silicone and released to the tooth surface through the silicone.

[0188] In this embodiment, controlling the 3D printing device according to the control instructions to produce material components for forming the orthodontic appliance according to the morphological information of the orthodontic appliance to be produced and forming the orthodontic appliance includes: controlling the 3D printing device according to the control instructions to produce material components for forming the orthodontic appliance according to the morphological information of the orthodontic appliance to be produced and forming the orthodontic appliance in a preset first manufacturing method, a preset second manufacturing method, a preset third manufacturing method, or a preset fourth manufacturing method. The preset first manufacturing method includes a spraying method or an extrusion method, for example, material extrusion, depositing molten thermoplastic plastic through a heated nozzle, extruding molten thermoplastic plastic wire through a heated nozzle, and stacking and forming the material layer by layer. The preset second manufacturing method includes a photopolymerization method, for example, irradiating a liquid photopolymer with a light source (such as a laser) to induce a chemical reaction and solidify it into a solid state. The preset third manufacturing method includes a melting method, for example, applying an energy source (such as a laser or electron beam) to a powder bed to melt and solidify the powder particles. The preset fourth manufacturing method includes an energy deposition method, for example, adding material to an existing component. During the molding process, it is necessary to feed the material (metal powder) and apply energy (laser, etc.) at the same time to melt and solidify the powder, so as to mold the material into the required area.

[0189] Of course, in other examples, there are other ways to control the 3D printing device according to the control instructions to produce the material components for the orthodontic device according to the morphological information of the orthodontic device to be manufactured as needed and to form the orthodontic device. As long as the manufacturing method is to control the 3D printing device according to the control instructions to produce the material components for the orthodontic device according to the morphological information of the orthodontic device to be manufactured as needed and to form the orthodontic device, it is within the scope of protection of this embodiment.

[0190] Specifically, in one example, the 3D printing device includes a first molding head and a second molding head, wherein the first molding head is used to manufacture fluoride, and the second molding head is used to manufacture silicone. Correspondingly, according to the control instruction, the 3D printing device is controlled to manufacture the material components for the molding of the orthodontic appliance in accordance with the morphological information of the orthodontic appliance to be manufactured on demand in a preset first manufacturing method and form the orthodontic appliance, including: obtaining the component ratio information of the fluoride component sample in the orthodontic appliance, and then, according to the component ratio information, controlling the first molding head of the 3D printing device to pre-spray or extrude the volume of fluoride, and controlling the second molding head to pre-spray or extrude the volume of silicone; the volume of fluoride pre-sprayed or extruded by the first molding head refers to the volume of fluoride required to be sprayed or extruded in advance for the first molding head; the volume of silicone pre-sprayed or extruded by the second molding head refers to the volume of silicone required to be sprayed or extruded in advance for the second molding head. Finally, based on the morphological information of the desired appliance, the first shaping head is controlled to spray or extrude fluoride, and the second shaping head is controlled to spray or extrude silicone and stack them layer by layer to form the appliance. In this embodiment, the preset first manufacturing method includes a spraying method or an extrusion method.

[0191] In another example, the 3D printing device includes a first molding head and a second molding head, the second molding head including a first-type glue-dispensing component molding head and a second-type glue-dispensing component molding head; the first molding head is used to produce fluoride, and the second molding head is used to produce silicone; the first-type glue-dispensing component molding head is used to produce the first type of glue, and the second-type glue-dispensing component molding head is used to produce the second type of glue; the first type of glue and the second type of glue are fused to form the silicone. Accordingly, according to the control instructions, the 3D printing device is controlled to produce the material components for the orthodontic device according to the morphological information of the orthodontic device to be produced in a preset first manufacturing method, and to form the orthodontic device, including: first, obtaining component ratio information of the fluoride component, the first-type glue-dispensing component, and the second-type glue-dispensing component constituting the orthodontic device; then, based on the component ratio information, controlling the first molding head of the 3D printing device to pre-dispense or extrude the volume of fluoride, controlling the first-type glue-dispensing component molding head to pre-dispense or extrude the volume of the first type of glue, and controlling the second-type glue-dispensing component molding head to pre-dispense or extrude the volume of the second type of glue. Among them, the volume of fluoride pre-sprayed or extruded by the first molding head refers to the volume of fluoride that needs to be sprayed or extruded in advance for the first molding head; the volume of the first type of glue component molding head pre-sprayed or extruded by the first type of glue refers to the volume of the first type of glue component molding head pre-sprayed or extruded by the first type of glue; the volume of the second type of glue component molding head pre-sprayed or extruded by the second type of glue refers to the volume of the second type of glue component molding head pre-sprayed or extruded by the second type of glue. Finally, according to the morphological information of the orthodontic appliance to be made, the first molding head is controlled to spray or extrude fluoride, the first type of glue component molding head is controlled to spray or extrude the first type of glue, and the second type of glue component molding head is controlled to spray or extrude the second type of glue and stacked layer by layer to form the orthodontic appliance. In this embodiment, the first type of glue includes component A glue and the second type of glue includes component B glue.

[0192] In another example, the second molding head includes a first-class molding head for separating glue components and a second-class molding head for separating glue components. The first-class molding head for separating glue components sprays or extrude component A glue, and the second-class molding head for separating glue components sprays or extrude component B glue. In one example, the first-class molding head for separating glue components and the second-class molding head for separating glue components are branch nozzles of the second molding head. After the first-class molding head for separating glue components sprays or extrude component A glue and the second-class molding head for separating glue components sprays or extrude component B glue, they will merge at the intersection of their respective ejection ports or extrusion ports, thereby forming a mixture of component A glue and component B glue. The fluoride sprayed or extruded by the first molding head is then mixed to form the silicone rubber of the finished orthodontic appliance. It should be noted that since the first shaping head and the second shaping head are printed according to the shape of the orthodontic appliance, the fluoride sprayed or extruded by the first shaping head and the mixture of component A glue and component B glue formed by the second shaping head are fused in the process of printing the shape of the orthodontic appliance, so that the silicone component of the orthodontic appliance formed includes component A glue, component B glue and fluoride.

[0193] In this embodiment, a digital model of an orthodontic appliance with an anti-caries function is used to control the 3D printing device to eject or extrude silicone containing component A glue, component B glue and fluoride according to the input information of the orthodontic appliance to be manufactured as needed, thereby forming the orthodontic appliance.

[0194] In one example, the 3D printing device may eject the colloid alone or extrude the colloid alone.

[0195] In one embodiment, the 3D printing device includes a first molding head and a second molding head, the second molding head includes a first type of glue component molding head and a second type of glue component molding head; the first molding head is used to manufacture fluoride, and the second molding head is used to manufacture silicone, the first type of glue component molding head is used to manufacture the first type of glue, and the second type of glue component molding head is used to manufacture the second type of glue; the first type of glue and the second type of glue are fused into the silicone; correspondingly, the 3D printing device is controlled according to the control instruction to produce the morphological information of the orthodontic appliance as needed in accordance with the preset first manufacturing method to produce the material components for orthodontic molding and form the orthodontic appliance, including: obtaining the required The fluoride component, the first type of glue component and the second type of glue component constitute the component ratio information of the orthodontic appliance; according to the component ratio information, the first molding head of the 3D printing device is controlled to prefabricate the volume of fluoride sprayed or extruded, the molding head of the first type of glue component is controlled to prefabricate the volume of the first type of glue sprayed or extruded, and the molding head of the second type of glue component is controlled to prefabricate the volume of the second type of glue sprayed or extruded; the first molding head is controlled to spray or extrude fluoride, the molding head of the first type of glue component is controlled to spray or extrude the first type of glue, and the molding head of the second type of glue component is controlled to spray or extrude the second type of glue; the first type of glue includes component A glue, and the second type of glue includes component B glue. After obtaining component A glue and component B glue, the component A glue, the component B glue and the fluoride are evenly mixed, and then the mixed material is injected into the mold. Then, the mold after injection molding is dried and shaped, and finally, the molded orthodontic appliance is taken out from the mold and post-molding processing is performed.

[0196] It should be noted that the 3D printing device of this embodiment only sprays out silicone containing component A glue, component B glue and fluoride, and sprays the silicone into the mold, and the mold has the shape set by the orthodontic appliance.

[0197] In this embodiment, manufacturing an orthodontic appliance according to the morphological information of the orthodontic appliance to be manufactured as required using the mold according to the control instruction specifically includes the following steps: first, obtaining fluoride, a first type of glue and a second type of glue according to the proportion information of the components constituting the orthodontic appliance; wherein, the first type of glue includes component A glue, and the second type of glue includes component B glue. Then, according to the control instruction, the mold is shaped into a molding mold, and the molding mold has a molding form corresponding to the form of the orthodontic appliance to be manufactured. The molding form of the molding mold can manufacture the form of the orthodontic appliance to be manufactured. Then, the component A glue, the component B glue and the fluoride are evenly mixed, and the mixed material is injected into the molding mold. Finally, the molding mold after injection molding is dried and shaped, and the molded orthodontic appliance is taken out of the molding mold and subjected to post-molding processing.

[0198] It should be noted that the mold of this embodiment can be an intelligent mold that can automatically reshape itself in real time. For example, the mold is provided with a 3D printing device that receives control instructions to shape the mold into a molding mold.

[0199] Optionally, the orthodontic appliance enables the fluoride to have a predetermined release rate by at least one of the following methods: adjusting the proportion of fluoride in the predetermined ratio; in the injection molding step, applying different pressures to make the silicone have different average micropore diameters, and different average micropore diameters make the fluoride have different release rates; by adjusting the pressurization pressure, the average micropore diameter is adjusted to obtain a predetermined release rate.

[0200] Optionally, by adjusting the predetermined ratio and the average micropore diameter, the fluoride release rate can be varied, thereby enabling the braces to have an anti-caries function during treatment. In this embodiment, by varying the average micropore diameters or the fluoride ratio, braces with varying fluoride release rates are obtained.

[0201] Of course, in another example, the second molding head also includes a molding head of a third type of glue component. Correspondingly, the 3D printing device is controlled according to the control instruction to produce the morphological information of the orthodontic appliance as needed in a preset first manufacturing method to produce the material components for orthodontic molding and form the orthodontic appliance, including: first, obtaining the component ratio information of the fluoride component, the first type of glue component, the second type of glue component and the third type of glue component constituting the orthodontic appliance, and then, according to the component ratio information, controlling the first molding head of the 3D printing device to pre-spray or extrude the volume of fluoride, controlling the first type of glue component molding head to pre-spray or extrude the volume of the first type of glue, and controlling the second type of glue component molding head to pre-spray or extrude the volume of the second type of glue, and controlling the third type of glue component molding head to pre-spray or extrude the volume of the third type of glue.

In this example, the third type of adhesive includes a dye.

[0202] In other examples, the corresponding components can also be sprayed according to the positions of the fluoride component, the first type of glue component, the second type of glue component and the third type of glue component in the morphology of the appliance. For example, the first area, the second area, the third area and the fourth area of ​​the morphological information, the first type of glue component can be sprayed in the first area, the second type of glue component can be sprayed in the second area, the fluoride component can be sprayed in the third area, and the third type of glue component can be sprayed in the fourth area. For another example, the first type of glue component, the second type of glue component, the third type of glue component and the fluoride component can be fused and then sprayed into the first area and the second area.

Alternatively, the first type of glue component, the second type of glue component, the third type of glue component and the fluoride component can be fused and then sprayed into the second area and the third area. Of course, in other examples, the positions corresponding to the various components can also be other, and this embodiment is not specifically limited here.

[0203] By inputting user-specific input into the digital model of the appliance, the appliance generated by the 3D printing device controlled by the digital model is more suitable for the patient and meets their individual needs. Furthermore, by incorporating fluoride into the silicone component sample, accurate and efficient appliance design is achieved while also allowing fluoride to be continuously released to the tooth surface through saliva in the mouth, preventing tooth decay.

[0214] An embodiment of the present application provides a brace, which is manufactured by the brace manufacturing method described in the fifth embodiment.

[0215] Eighth embodiment

[0216] In the above-mentioned first embodiment, a method for digital modeling of an orthodontic appliance with an anti-caries function is provided. Correspondingly, the eighth embodiment of the present application provides a method for manufacturing an orthodontic appliance mold. The parts of this embodiment that are the same as those in the first embodiment will not be repeated. Please refer to the corresponding parts in the first embodiment.

[0217] Please refer to Figure 6, which is a flow chart of a method for manufacturing an appliance mold according to the eighth embodiment of this application. This method uses a preset manufacturing device to manufacture the appliance mold based on the appliance digital model generated by the method for generating a digital model of an appliance with anti-caries function described in the first embodiment. The appliance digital model is used to obtain the appliance's morphological information and material composition based on input information used to manufacture the appliance. The method comprises the following steps:

[0218] Step S601: obtaining input information of an orthodontic appliance to be manufactured; the input information includes morphological information and silicone components corresponding to the morphological information, wherein the morphological information describes morphological features of the orthodontic appliance.

[0219] This input information can be set based on the patient's actual orthodontic needs. It primarily includes information about the tooth morphology and the silicone composition. The silicone composition includes at least fluoride, which is absorbed into the silicone and released onto the tooth surface through the silicone. The morphological information describes the morphological characteristics of the appliance.

[0220] Step S602: Obtain manufacturing information of the appliance mold to be manufactured based on the input information.

[0221] In this step, the manufacturing information of the appliance mold to be made is obtained according to the input information, including: first, determining the morphological information and material composition of the appliance according to the input information, and the morphological information includes the outer surface morphological information. Based on the morphological information to describe the morphological characteristics of the appliance, the digital model of the appliance can construct the appliance according to the morphological information. The input information contains the morphological characteristics of the appliance, so that the morphological information and material composition of the appliance can be obtained according to the input information, and the morphological information includes the outer surface morphological information. Then, the inner contour information of the appliance mold corresponding to the outer surface morphological information of the appliance is determined. The appliance mold can be used to manufacture the appliance, which is generally done by injecting silicone into the appliance mold. The inner surface of the appliance mold has the shape and structure of the appliance to be manufactured. After the silicone is injected into the appliance mold, the corresponding appliance can be manufactured according to the shape and structure of the inner surface of the appliance mold. It can be seen that the outer surface morphology of the appliance is the morphology of the inner surface of the appliance mold. Based on the digital model of the orthodontic appliance, the orthodontic appliance can be constructed according to the morphological information, and the outer surface morphology of the orthodontic appliance can also be obtained at the same time, thereby correspondingly obtaining the inner surface morphology of the orthodontic appliance mold. The morphology of the inner surface of the orthodontic appliance mold and the outer surface morphology of the orthodontic appliance are mutually compatible.

[0222] It should be noted that, in this embodiment, the inner contour information of the appliance mold corresponding to the outer surface morphology information of the appliance is also obtained by the appliance digital model through a large amount of training data. This training data is the morphological samples of the inner surface of the appliance mold and the outer surface of the appliance. The inner surface morphological samples of the appliance mold and the outer surface morphological samples of the appliance are input into the appliance digital model. By comparing the output results, if the consistency of the output results reaches a preset threshold, the trained appliance digital model can be used. If the consistency of the output results does not reach the preset threshold, iterative training continues until the consistency of the output results reaches the preset threshold.

[0223] In this embodiment, the inner contour information of the appliance mold includes the inner contour shape of the appliance mold and the coordinate information corresponding to the inner contour shape. Since the appliance mold is a solid object and the inner contour information is a shape, which can be understood as a surface, it is necessary to obtain the coordinate information corresponding to the inner contour shape.

[0224] After obtaining the coordinate information corresponding to the inner contour, the relative wall thickness information for the inner contour of the appliance mold is obtained based on the material composition. The material composition can clearly define the relative wall thickness information for the inner contour, thereby allowing the physical appliance mold to be molded according to the specified material. Finally, the manufacturing information for the appliance mold to be manufactured is obtained based on the inner contour information of the appliance mold and the relative wall thickness information for the inner contour of the appliance mold.

[0225] Step S603: Sending control instructions to the preset manufacturing device according to the manufacturing information.

[0226] After obtaining the manufacturing information of the appliance mold to be manufactured, control instructions are transmitted to the preset manufacturing device according to the manufacturing information. In this step, the manufacturing information needs to be processed to convert it into instruction information that can be executed by the preset manufacturing device.

[0227] Step S604: controlling the preset manufacturing device to manufacture an appliance mold according to the control instruction.

[0228] In this embodiment, the preset manufacturing device includes a 3D printing device, a controllable machine tool, or an intelligent mold manufacturing device or a molding device. Of course, in other examples, any device that can form and manufacture a mold is within the scope of protection of this embodiment. Taking a 3D printing device as an example, controlling the preset manufacturing device to manufacture an orthodontic appliance mold according to the control instructions includes: controlling the 3D printing device to produce a material component for molding the orthodontic appliance mold and forming the orthodontic appliance according to the control instructions; the molded orthodontic appliance mold is used to shape the orthodontic appliance. Specifically, in this embodiment, controlling the 3D printing device to produce a material component for molding the orthodontic appliance mold and forming the orthodontic appliance mold according to the control instructions includes: controlling the 3D printing device to produce a material component for molding the orthodontic appliance mold and forming the orthodontic appliance mold according to the control instructions in a preset first manufacturing method, a preset second manufacturing method, a preset third manufacturing method, or a preset fourth manufacturing method according to the control instructions; wherein the preset first manufacturing method includes a spraying method or an extrusion method, for example, material extrusion, depositing molten thermoplastic plastic through a heated nozzle, extruding molten thermoplastic plastic wire through a heated nozzle, and stacking and molding layer by layer. The preset second manufacturing method includes a photocuring molding method, for example, using a light source (such as a laser) to irradiate a liquid photopolymer to trigger a chemical reaction to solidify it into a solid state. The preset third manufacturing method includes a melting method, for example, by applying an energy source (such as a laser or an electron beam) to a powder bed to melt and solidify the powder particles. The preset fourth manufacturing method includes an energy deposition method, for example, adding material to an existing component. During the molding process, it is necessary to feed the material (metal powder) and apply energy (laser, etc.) at the same time to melt and solidify the powder, so as to mold the material in the required area.

[0229] Specifically, after obtaining the control instruction, the shaping head of the 3D printing device is controlled according to the control instruction to spray out the material body for forming the orthodontic appliance mold. In this embodiment, the material body for forming the orthodontic appliance mold includes a soft material or a hard material, wherein the soft material includes a colloid, a resin or a soft material; the hard material includes metal (powder), lime (powder), and the powdered material contains glue that can be molded after drying, so that the powdered material is dried and molded after being sprayed out. In one example, the orthodontic appliance mold after printing and injection molding the colloid is placed in a drying oven. When drying, the appropriate temperature and time can be selected according to the specific situation. A possible parameter selection is: setting the drying and shaping temperature to 50-250 degrees and the drying and shaping time to 10-60 minutes. Take out the orthodontic appliance mold and cool it to room temperature. Finally, the orthodontic appliance mold is processed after molding, such as trimming.

[0230] In addition, it should be noted that the 3D printing device of this embodiment has more functions than the 3D printing device used for printing and manufacturing orthodontic appliances. It can not only print soft materials, but also print and manufacture hard materials.

[0231] In addition, the method of controlling a controllable machine tool or an intelligent mold manufacturing device according to the control instructions to manufacture an orthodontic mold is similar to or the same as the method of controlling a 3D printing device according to the control instructions to manufacture an orthodontic mold, and will not be described in detail here.

[0232] This embodiment improves the accuracy and efficiency of appliance mold production by inputting user-defined input information into a digital appliance model. This information then allows the digital appliance model to obtain manufacturing information for the appliance mold to be produced based on the input information. This information then controls the 3D printing device to generate the appliance mold. Furthermore, the generated appliance mold is more suitable for the patient and meets their individual needs.
