[0002] Silicone orthodontic appliances are widely used in the treatment of malocclusion in children, and have a good effect on correcting bad oral habits, inducing tooth eruption, and establishing normal occlusion.

[0003] In related technologies, silicone orthodontic appliances are divided into two categories: prefabricated and custom-made. Prefabricated silicone orthodontic appliances are mass-produced products. The product series of prefabricated silicone orthodontic appliances includes multiple sizes, and the appropriate size is selected based on the patient's oral condition in clinical application. Custom-made silicone orthodontic appliances are produced by manually creating molds based on the patient's dental and maxillofacial data and specific conditions.

[0056] Many specific details are set forth in the following description to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application; therefore, this application is not limited to the specific embodiments disclosed below.

[0057] Silicone orthodontic appliances are widely used in the treatment of malocclusion in children, and have a good effect on correcting bad oral habits, inducing tooth eruption, and establishing normal occlusion.

[0058] In related technologies, silicone orthodontic appliances are divided into two categories: prefabricated and custom-made. Prefabricated silicone orthodontic appliances are mass-produced products. The product series of prefabricated silicone orthodontic appliances includes multiple sizes, and the appropriate size is selected based on the patient's oral condition in clinical application. Custom-made silicone orthodontic appliances are produced by manually creating molds based on the patient's dental and maxillofacial data and specific conditions. Compared to prefabricated silicone orthodontic appliances, custom-made silicone orthodontic appliances better conform to the patient's dental and maxillofacial features, offering better applicability and comfort.

[0059] However, regardless of whether the orthodontic appliance is prefabricated or custom-made, it has a certain weight for the patient, and long-term wear can cause discomfort, thus affecting compliance and further reducing treatment effectiveness; for the manufacturer, the solid structure of the appliance uses a lot of material. If...

[0060] Therefore, embodiments of this application provide a method for manufacturing an orthodontic appliance, which can modify the structure of the appliance, reduce patient discomfort, improve wearing effect, and save materials and reduce production costs. This application also relates to an apparatus for manufacturing an orthodontic appliance, an electronic device, and a computer storage medium.

[0061] The present application will be described in detail below with reference to several embodiments and accompanying drawings.

[0062] First Embodiment

[0063] The first embodiment of this application provides a method for manufacturing an orthodontic appliance, which is described below in conjunction with... Figure 1 The manufacturing method of this orthodontic appliance is described in detail. Figure 1 This is a schematic flowchart illustrating a method for manufacturing an orthodontic appliance according to the first embodiment of this application. The method includes the following steps:

[0064] Step S101: Obtain impression morphology information for generating orthodontic appliance impressions.

[0065] In this step, obtaining the impression morphology information used to generate the orthodontic appliance impression specifically includes, firstly, 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. These oral parameters are obtained through the following methods: by using an intraoral scanner or the patient's dental impression; or by using an intraoral scanner or articulator; or by using optical scanning technology, X-ray imaging technology, ultrasound imaging technology, computed tomography (CT) scanning, or magnetic resonance imaging (MRI).

[0066] Then, based on oral parameters, overall morphological information and alveolar morphological information for generating the orthodontic appliance impression are obtained. Obtaining the overall morphological information based on oral parameters includes: obtaining the length and width information of the upper and lower dentition based on oral parameters. In one example, the width information of each upper and lower dentition can be calculated and fitted using incisor width, intercanine width, and intermolar width. Simultaneously with obtaining the incisor width, intercanine width, and intermolar width, the corresponding positional information of the incisors, canines, and molars can be obtained. The length information of the upper and lower dentition is 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 of the upper and lower dentition, the distance between the occlusal surfaces of the upper and lower dentition is obtained. The distance between the occlusal surfaces clarifies the degree of maxillary and mandibular opening. Finally, based on the length and width information of the upper and lower dentition, and the distance between the occlusal surfaces of the upper and lower dentition, the overall morphological information for generating the orthodontic appliance impression is obtained.

[0067] In this implementation, alveolar morphology information for generating orthodontic appliance impressions is obtained based on oral parameters, including: the morphology of the labial / buccal and lingual contours of the upper and lower dentition, and the gingival position of each tooth in the upper and lower dentition. Then, the morphology of the labial / buccal and lingual contours and the gingival positions of each tooth are smoothed by connecting lines to determine the processed standard morphology. For example, the length of the alveolar ridge wall is fitted and adjusted based on the smoothed gingival position lines between two teeth in different dentition regions (such as incisors, canines, molars, etc.). The length of the alveolar ridge wall is sufficient to ensure that the orthodontic appliance does not compress the gingiva; if the length of the orthodontic appliance's outer wall does not reach the gingival position, then the alveolar morphology information for generating orthodontic appliance impressions is obtained based on the standard morphology.

[0068] After obtaining the overall morphological information and alveolar morphological information, the impression morphological information used to generate the orthodontic appliance impression is obtained based on the overall morphological information and alveolar morphological information.

[0069] Step S102: Control the molding device to manufacture the target molding according to the molding shape information.

[0070] After obtaining the impression shape information for generating the orthodontic appliance impression, the impression device is controlled to manufacture the target impression based on the impression shape information. Specifically, in this step, controlling the impression device to manufacture the target impression body based on the impression shape information includes the following steps:

[0071] First, the impression contour information is obtained from the impression morphology information. This impression contour information includes the external contour information of the orthodontic appliance to be manufactured. The overall external shape of the orthodontic appliance can be manufactured based on the impression contour information; that is, the impression device is controlled to manufacture the initial impression based on the impression contour information. In one example, the impression device can be a 3D impression printing device, and the initial impression is manufactured based on the impression contour information.

[0072] In this embodiment, since the specific shape of each orthodontic appliance differs, the initial impression needs to be modified according to the specific impression shape information to obtain the target impression that meets the requirements. Specifically, the impression shape information is input into a pre-generated digital model of the orthodontic appliance impression to control the impression device to modify the initial impression in order to obtain the target impression.

[0073] It should be further explained that, in this embodiment, the pre-generated digital model of the orthodontic appliance impression is generated as follows: The overall morphological information and alveolar morphological information used to generate the orthodontic appliance impression are acquired, and the overall morphological information and alveolar morphological information are standardized and normalized. This ensures that different attributes have the same scale and a unified representation, facilitating subsequent model training and comparison. After completing the extraction and data processing of the overall morphological information and alveolar morphological information, machine learning algorithms can be used to build the digital model of the orthodontic appliance impression. Common methods include decision trees, support vector machines, random forests, and deep learning. The choice of a suitable algorithm depends on the size of the dataset, the type of features, and performance requirements. Specifically, the morphological information samples and silicone component samples used as training sample groups are input into the initial digital model of the orthodontic appliance impression for iterative training. After training a certain number of samples, the initial digital model of the orthodontic appliance impression is validated by the morphological information samples and silicone component samples of the detection sample group. If the output result meets the preset standard, the digital model of the orthodontic appliance impression is generated. If the output does not meet the preset standard, iterative training continues until the output meets the preset standard to generate a digital model of the orthodontic appliance impression. After establishing the digital model, it needs to be evaluated to ensure its performance. Evaluation can use metrics such as accuracy, recall, and precision. Cross-validation, test set validation, or matching with known devices can be used to evaluate the model's performance. Furthermore, the digital model of the orthodontic appliance impression needs to be updated and maintained over time to adapt to new devices and technologies. This may require periodically re-collecting impression information, updating the extraction of overall morphological and alveolar morphological information from the impression, or adopting a new digital model of the orthodontic appliance impression.

[0074] Step S103: Obtain the orthodontic appliance preparation film, cover the target impression with the orthodontic appliance preparation film, and then manufacture the orthodontic appliance preparation film into a target orthodontic appliance with a hollow structure according to a preset manufacturing method.

[0075] After creating the target impression, current technology typically involves injection molding the material for the orthodontic appliance into the target impression to obtain the corresponding appliance. However, existing injection molding methods result in relatively heavy appliances, which can cause discomfort with prolonged wear, affecting adherence and further reducing treatment effectiveness. For manufacturers, the solid structure of the appliance also requires a significant amount of material. Therefore, this paper proposes a method to modify the appliance structure to reduce patient discomfort, improve wearing effectiveness, and simultaneously save materials and reduce production costs.

[0076] Specifically, in this embodiment, after manufacturing the target impression, an orthodontic appliance preparation film is obtained. This film is then placed over the target impression and manufactured into a hollow target orthodontic appliance according to a preset manufacturing method. In this embodiment, the orthodontic appliance preparation film is relatively thin, perhaps 1 mm, but its post-molding hardness meets the orthodontic appliance's corrective requirements. The orthodontic appliance preparation film may contain a mixture of silicone and fluoride. The silicone includes a first type of adhesive and a second type of adhesive, which react with each other to generate an orthodontic appliance preparation film with an internal microporous structure. The first and second types of adhesives do not react with the fluoride. The fluoride can be adsorbed into the orthodontic appliance preparation film with the internal microporous structure. Of course, in other examples, the orthodontic appliance preparation film may contain only silicone.

[0077] In this embodiment, a hollow target orthodontic appliance can be manufactured by using a pre-defined manufacturing method based on the specific shape of the target impression and the orthodontic appliance preparation film. Specifically, in one example, the inner contour of the target impression manufactured by the impression device is controlled according to the impression shape information to have a structural shape adapted to the target orthodontic appliance. This means that the printing pattern that can print the shape of the target orthodontic appliance is set inside the target impression. After obtaining the inner contour of the target impression, the orthodontic appliance preparation film is applied to the inner contour of the target impression, and the film is heated and blown to form a hollow target orthodontic appliance. Specifically, the unfolded area of ​​the orthodontic appliance preparation film completely covers the inner contour of the target impression, or the film is placed at any position within the inner contour of the target impression; this arbitrary position can be referred to as the film forming position. After applying the orthodontic appliance preparation film, the heating and blowing / suction device is turned on to heat and inflate the film, softening it and shaping it according to the printed pattern of the target orthodontic appliance. After shaping, heating and blowing are stopped, allowing the film to cool gradually and sealing the formed areas, resulting in a hollow initial orthodontic appliance. Finally, the initial orthodontic appliance containing the target impression undergoes pretreatment to form the target orthodontic appliance. Specifically, a dissolving and reducing solution is used to react with the target impression, causing it to dissolve and detach from the initial orthodontic appliance. The remaining orthodontic appliance preparation film from the initial orthodontic appliance is then cleaned, and the sealed areas are deburred to create the target orthodontic appliance. This ensures the target orthodontic appliance not only meets the user's requirements but is also smooth and aesthetically pleasing.

[0078] Of course, in one example, the target impression can also be constructed directly as a hollow structure, so that the impression does not need to be dissolved. That is, the orthodontic device preparation membrane encapsulates the hollow target impression, thereby forming a hollow target orthodontic device.

[0079] In another example, the outer contour of the target impression manufactured by the impression device can be controlled according to the impression shape information to have a structural shape adapted to the target orthodontic appliance. This means that the printed pattern of the target orthodontic appliance's shape is set on the outside of the target impression. After obtaining the outer contour of the target impression, an orthodontic appliance preparation film is wrapped around the outer contour of the target impression, and the film is heated and adsorbed to form a hollow initial orthodontic appliance. Specifically, the unfolded area of ​​the orthodontic appliance preparation film completely covers the outer contour of the target impression. After the film is applied, a heating blower / suction device is turned on to heat and draw air from the film, softening it and allowing it to conform to the printed pattern of the target orthodontic appliance's shape for shaping. After shaping, the heating and blowing of the orthodontic diaphragm is stopped, allowing the orthodontic diaphragm to gradually cool down, thus forming the initial orthodontic diaphragm with a hollow structure.

[0080] Finally, the initial orthodontic appliance containing the target impression is pre-treated to form the target orthodontic appliance. Specifically, the sealing position of the initial orthodontic appliance is determined, a dissolving and reducing solution is obtained, and the dissolving and reducing solution reacts with the target impression through the sealing position, so that the target impression dissolves and detaches from the initial orthodontic appliance. The sealing position is then sealed, the remaining orthodontic appliance preparation film of the initial orthodontic appliance is cleaned, and the sealing position of the initial orthodontic appliance is deburred to form the target orthodontic appliance. This ensures that the target orthodontic appliance is not only shaped to meet the user's needs but is also smooth and aesthetically pleasing.

[0081] In another example, the target impression manufactured by the impression device, controlled according to impression shape information, includes a first impression and a second impression. That is, the target impression is composed of the first and second impressions, which can be joined together to form the target impression. After obtaining the first impression, the first part of the orthodontic appliance preparation film is applied to the first part of the target impression, and the first part of the orthodontic appliance preparation film is heated and blown into shape to create a shell-like first part of the orthodontic appliance. Specifically, the unfolded area of ​​the first part of the orthodontic appliance preparation film completely covers the first part of the target impression. After applying the first part of the orthodontic appliance preparation film, the heating blower / suction device is turned on to heat and blow the first part of the orthodontic appliance preparation film, softening it and shaping it according to the printed pattern of the target orthodontic appliance. After shaping, the heating and blowing of the first part of the orthodontic appliance preparation diaphragm is stopped, allowing it to gradually cool and form a shell-like structure for the first part of the orthodontic appliance. Finally, the remaining orthodontic appliance preparation diaphragm in the first part of the appliance is cleaned.

[0082] Similarly, after obtaining the second impression, the second part of the orthodontic appliance preparation film is applied to the second part of the target impression, and the second part of the orthodontic appliance preparation film is heated and blown into shape to form a shell-like second orthodontic appliance assembly. Specifically, the unfolded area of ​​the second part of the orthodontic appliance preparation film completely covers the second part of the target impression. After applying the second part of the orthodontic appliance preparation film, the heating blower / suction device is turned on to heat and blow into the second part of the orthodontic appliance preparation film, softening it and shaping it according to the printed pattern of the target orthodontic appliance. After shaping, the heating and blowing of the second part of the orthodontic appliance preparation film is stopped, allowing the orthodontic appliance preparation film to gradually cool, thereby forming the shell-like structure of the second orthodontic appliance assembly. Finally, the remaining orthodontic appliance preparation film of the second orthodontic appliance assembly is cleaned.

[0083] After fabricating the first and second orthodontic components, the shell-like components are joined together to create a hollow target orthodontic appliance. In one example, the joint between the first and second components can be roughened to ensure that the target orthodontic appliance not only meets the user's needs but is also smooth and aesthetically pleasing.

[0084] This application provides a method for manufacturing an orthodontic appliance, including: obtaining impression morphology information for generating an orthodontic appliance impression; controlling an impression device to manufacture a target impression based on the impression morphology information; obtaining an orthodontic appliance preparation film; covering the target impression with the orthodontic appliance preparation film; and fabricating the orthodontic appliance preparation film into a hollow target orthodontic appliance according to a preset manufacturing method. This application uses the impression morphology information to prepare the target impression, and then uses an orthodontic appliance preparation film to replace the injection molding material used in the prior art. Instead of using injection molding to manufacture the orthodontic appliance, the orthodontic appliance preparation film is covered with the target impression and fabricated into a hollow target orthodontic appliance according to a preset manufacturing method. This not only changes existing solid orthodontic appliances to hollow orthodontic appliances, but also reduces patient discomfort, improves wearing effect, saves materials, and reduces production costs.
