Description

Technical Field

[0001] The present invention relates to the technical field of dental appliance design, and more specifically, to a method for manufacturing a textured diaphragm dental appliance and the dental appliance. Background Art

[0002] With the development of economy and the progress of society, more and more people choose to receive orthodontic treatment for aesthetic or functional requirements. Wearing dental braces is an effective way of orthodontics.

[0003] By enhancing the wrapping ability of dental braces on teeth, the energy and torque transmission during the correction process can be increased, which can improve the correction efficiency. Some manufacturers improve dental braces by seeking new materials with excellent mechanical properties. However, since new materials need to be verified from the microstructure, the rationality of their application in the field of braces needs to be proved from the perspectives of mechanical properties, light transmittance, biocompatibility, etc., and their usability needs to be proved from the perspectives of mechanical properties, light transmittance, biocompatibility, etc. Moreover, a complete set of preparation processes needs to be studied, which has a long R&D cycle and high cost. In addition, as an industrial product, the number of samples produced in a batch is very large. If the experimental verification link is not used up or fails to achieve the expected results, it will cause great waste.

[0004] In addition to exploring new materials, in order to increase the fit between the appliance and the teeth, many manufacturers also adopt the method of adding accessories to the teeth. The accessories are small buckles installed on the teeth, which can greatly increase the wrapping of the appliance and the teeth, and provide a torque fulcrum, thereby improving the accuracy and expression efficiency of the correction force transmission. The length, width and height of the accessories are generally 4mm*2mm*1mm, and the single-step correction step distance of the dental transparent braces is generally 0.25mm. If the accessory design is too small and the height of the accessory is too low, the wrapping performance of the appliance on the accessory will be reduced, and it will not be able to provide a fulcrum, and the mechanical transmission ability will be deteriorated. If the accessory design is too large, it will rub the mouth, increase the friction between the teeth and the mouth, and reduce the wearing comfort; in addition, the average length and width of the visible part of human teeth is 8mm*6mm, and the area of ​​the accessories exceeds 15% of the tooth area, which also greatly reduces the wearing comfort and aesthetics.

[0005] Therefore, how to improve the wrapping between the braces and teeth while reducing the size of the braces without changing the materials of traditional dental braces is a technical problem that needs to be solved urgently. Summary of the invention

[0006] In order to solve the problem of how to improve the wrapping between the appliance and the teeth and reduce the size of the appliance without changing the material of the traditional dental appliance, the present invention proposes a method for manufacturing a textured diaphragm dental appliance. The method does not require the development of new materials and is simple to manufacture. Moreover, the anti-slip performance of the appliance is increased without changing the mechanical and biological properties of the appliance itself, and the wrapping and fit between the appliance and the teeth are improved. A dental appliance is also proposed, which has high wearing comfort and strong wrapping, thereby facilitating improving the efficiency of dental correction.

[0007] To solve the above problems, the technical solution adopted in this application is:

[0008] On the one hand, the present application provides a method for manufacturing a hairy membrane dental appliance, the manufacturing method comprising:

[0009] Obtain the patient's dental model;

[0010] Roughening of dental orthodontic membranes;

[0011] The textured dental orthodontic membrane is heated and melted, and the textured surface of the molten and textured dental orthodontic membrane is covered on the dental model;

[0012] A vacuum operation is performed under the dental model covered with the dental orthodontic membrane to make the roughened texture surface of the dental orthodontic membrane fit and cover the dental model;

[0013] After the dental orthodontic diaphragm is cooled and formed, the dental orthodontic diaphragm is separated from the dental jaw model to obtain a textured diaphragm dental orthodontic appliance.

[0014] In this technical solution, the dental orthodontic diaphragm is made of traditional materials. During the manufacturing process, the dental orthodontic diaphragm is roughened. Without changing the mechanical and biological properties of the dental orthodontic diaphragm itself, the anti-slip performance of the manufactured dental appliance is increased. The contact surface between the dental appliance and the teeth is added with a roughened texture, which improves the wrapping and fit between the appliance and the teeth.

[0015] Preferably, the texturing treatment is laser texturing treatment, and the process of texturing the dental orthodontic membrane is as follows:

[0016] Setting parameters of laser texturing, including laser pulse frequency, finite pulse step length, laser wavelength and texturing texture spacing;

[0017] The laser pulse beam is turned on, and after the laser pulse beam is focused on the surface of the dental orthodontic membrane to be textured, the laser pulse beam is incident on the surface of the dental orthodontic membrane to texture it according to the mesh texture, thereby obtaining a textured dental orthodontic membrane.

[0018] According to the above technical means, a roughened mesh texture is formed on the surface of the orthodontic membrane to increase the anti-slip performance.

[0019] Preferably, the laser roughening parameters are obtained by iterative optimization through machine learning under a limited number of tensile bending stress tests and roughness tests on the orthodontic diaphragm, so that the obtained laser roughening parameters are more reasonable.

[0020] Preferably, the textured dental orthodontic membrane is heated to 230 degrees Celsius for 20 seconds, so that the dental orthodontic membrane is in a molten state, so as to be easily covered and fitted on the dental model.

[0021] Preferably, the method for manufacturing the textured diaphragm dental appliance further comprises: cutting and polishing along the edge of the textured diaphragm dental appliance to improve the fit of the manufactured textured diaphragm dental appliance.

[0022] On the other hand, the present application also proposes a textured diaphragm dental appliance, wherein the textured diaphragm dental appliance is manufactured by the textured diaphragm dental appliance manufacturing method.

[0023] Preferably, the textured surface of the textured membrane dental appliance fits the teeth.

[0024] Preferably, the texture of the textured membrane dental appliance is a reticular texture, and the texture spacing is 0.975 mm.

[0025] According to the above technical means, the textured texture spacing of the textured diaphragm dental appliance is small, and compared with the traditional addition of dental appliance accessories, the foreign body sensation when worn is lower. While improving the wrapping of the appliance on the teeth, the wearing comfort is improved, which can further improve the efficiency of dental correction.

[0026] Preferably, the thickness of the dental orthodontic membrane used to make the textured membrane dental appliance is 0.75 mm.

[0027] Preferably, the dental orthodontic diaphragm used to make the textured diaphragm dental appliance is made of TPU material.

[0028] According to the above technical means, the TPU material used is a traditional dental orthodontic diaphragm material, and its mechanical properties, biocompatibility and water absorption properties can all remain unchanged.

[0029] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0030] The present invention proposes a method for manufacturing a textured diaphragm dental appliance and a dental appliance. In the method for manufacturing a textured diaphragm dental appliance, a dental model is made, a dental appliance diaphragm is textured, and a heating and shaping operation is performed in sequence, wherein a textured texture is added to the contact surface between the dental appliance and the teeth, and the dental appliance diaphragm is made of traditional materials. Under the premise of not changing the mechanical and biological properties of the dental appliance diaphragm itself, the anti-slip performance of the manufactured dental appliance is increased, and the wrapping and fit between the appliance and the teeth are improved. Compared with the traditional dental appliance accessories, the dental appliance manufactured in this way has a lower foreign body sensation when worn, and while improving the wrapping of the appliance on the teeth, it also improves the wearing comfort, which can further improve the efficiency of dental correction.

[0043] Example 1

[0044] like Figure 1 As shown, this embodiment proposes a method for manufacturing a hairy diaphragm dental appliance, see Figure 1 , the steps of the production method include:

[0045] S1: Obtain the patient's dental model;

[0046] S2: roughening the dental orthodontic membrane;

[0047] S3: heating and melting the textured dental orthodontic membrane, and covering the molten and textured surface of the textured dental orthodontic membrane on the dental model;

[0048] S4: performing a vacuum operation under the dental model covered with the dental orthodontic membrane, so that the roughened texture surface of the dental orthodontic membrane fits and covers the dental model;

[0049] S5: After the dental orthodontic membrane is cooled and formed, the dental orthodontic membrane is separated from the dental model to obtain a textured membrane dental orthodontic appliance.

[0050] In this embodiment, it should be noted that the selected dental orthodontic membrane is a dental orthodontic membrane made of traditional materials. When obtaining the patient's dental model during the production of the textured membrane dental appliance, an oral scanner can be used to obtain the actual dental model of the patient's oral cavity, and a silicone rubber dental model of the patient's oral cavity can also be obtained by impression. The method of obtaining the dental model is not limited in this embodiment. As a preferred method, this embodiment uses a light-curing 3D printer to print the patient's dental model.

[0051] Then, the dental orthodontic diaphragm is roughened. In this embodiment, the roughening treatment is laser roughening. The process of roughening the dental orthodontic diaphragm is as follows:

[0052] Setting parameters of laser texturing, including laser pulse frequency, finite pulse step length, laser wavelength and texturing texture spacing;

[0053] The laser pulse beam is turned on, and after the laser pulse beam is focused on the surface of the dental orthodontic membrane to be textured, the laser pulse beam is incident on the surface of the dental orthodontic membrane to texture it according to the mesh texture, thereby obtaining a textured dental orthodontic membrane.

[0054] The laser texturing processor used is a carbon dioxide laser, wherein the laser texturing parameters are obtained by iterative optimization through machine learning under a limited number of orthodontic diaphragm tensile bending stress tests and roughness tests, so that the obtained laser texturing parameters are more reasonable. The laser texturing parameters of this embodiment are shown in Table 1.

[0056]

[0057] Figure 2 A schematic diagram of an electron microscope photograph of the laser roughening texture proposed in an embodiment of the present invention is shown. Without changing the mechanical and biological properties of the dental orthodontic membrane itself, the anti-slip performance of the manufactured dental appliance is increased, and the contact surface between the dental appliance and the teeth is added with a roughened texture, thereby improving the wrapping and fit between the appliance and the teeth.

[0058] In S3, the conditions for heating and melting the textured dental orthodontic membrane are as follows: heating the textured dental orthodontic membrane to 230 degrees Celsius for 20 seconds, so that the dental orthodontic membrane is in a molten state, so as to facilitate covering and fitting on the dental model.

[0059] In addition, the method for manufacturing the textured diaphragm dental appliance also includes: cutting and grinding along the edge of the textured diaphragm dental appliance to improve the fit of the textured diaphragm dental appliance. The textured diaphragm dental appliance is as follows: Figure 3 shown.

[0060] Example 2

[0061] See also Figure 4 This embodiment proposes a textured diaphragm dental appliance, which is manufactured using the textured diaphragm dental appliance manufacturing method described in Example 1. In this embodiment, the textured surface of the textured diaphragm dental appliance fits the teeth.

[0062] The texture of the textured diaphragm dental appliance is a mesh texture with a texture spacing of 0.975mm. The texture spacing of the textured diaphragm dental appliance is small. Compared with the traditional addition of dental appliance accessories, the foreign body sensation when wearing is lower. While improving the wrapping of the appliance on the teeth, the wearing comfort is improved, which can further improve the efficiency of dental correction.

[0063] In this embodiment, the thickness of the dental orthodontic membrane used to make the textured membrane dental appliance is 0.75 mm.

[0064] In this embodiment, the dental orthodontic membrane used to make the textured membrane dental appliance is made of TPU material.

[0065] Compared with traditional dental appliances, the textured diaphragm dental appliance proposed in this embodiment has the following advantages:

[0066] (1) Achieved high roughness;

[0067] The contact surface between the dental appliance and the teeth proposed in this embodiment is added with a mesh roughened texture, the texture spacing is 0.975 mm, and the arithmetic mean height of the roughness after roughening is about 33.9 μm.

[0068] (2) High mechanical properties and biocompatibility;

[0069] The dental appliance proposed in this embodiment is physically processed using traditional TPU material, and the mechanical properties, biocompatibility, and water absorption properties after processing are no different from those of TPU material.

[0070] (3) High comfort and aesthetics;

[0071] The dental appliance proposed in this embodiment has no accessories, but increases the fit between the dental appliance and the teeth, thereby improving comfort and aesthetics compared to a dental appliance with accessories.

[0072] Example 3

[0073] This example verifies the effectiveness of the dental appliance proposed in the present invention by comparing the retention force and correction transmission energy of a textured diaphragm dental appliance and a non-textured diaphragm dental appliance on teeth.

[0074] In the comparative experiment, first, the retention force of the hairy diaphragm dental appliance and the non-hairy diaphragm dental appliance on the teeth is compared, including the retention force of the hairy diaphragm dental appliance without attachments and the non-hairy diaphragm dental appliance without attachments, the retention force of the hairy diaphragm dental appliance with attachments and the non-hairy diaphragm dental appliance with attachments, and the retention force of the teeth of several volunteers wearing the hairy diaphragm dental appliance and the non-hairy diaphragm dental appliance. In this embodiment, if Figure 5As shown in the figure, the dental appliance without attachments and hairy diaphragm has a 19.8% higher retention force on teeth than the dental appliance without attachments and hairy diaphragm, and the dental appliance with attachments and hairy diaphragm has a 46.8% higher retention force on teeth than the dental appliance with attachments and hairy diaphragm. Figure 5 The comparison of tooth retention force between 5 volunteers wearing textured diaphragm dental appliances and wearing non-texturized diaphragm dental appliances was shown. Overall, the tooth retention force of wearing textured diaphragm dental appliances was improved by 74.4% compared with wearing non-texturized diaphragm dental appliances.

[0075] Secondly, if Figure 6 As shown in the figure, the comparison of the correction energy transmitted to teeth by the textured diaphragm dental appliance and the non-texturized diaphragm dental appliance includes the comparison of the correction energy transmitted to teeth by the textured diaphragm dental appliance without attachment and the non-texturized diaphragm dental appliance without attachment, the comparison of the correction energy transmitted to teeth by the vertical attachment textured diaphragm dental appliance and the vertical attachment non-texturized diaphragm dental appliance, and the comparison of the energy transmitted to teeth by the torsion attachment textured diaphragm dental appliance and the torsion attachment textured diaphragm dental appliance, among which the vertical attachment is divided into 4mm size and 3mm size. Through the above comparison, Figure 6 The correction energy transmitted by the dental appliance with textured diaphragm without attachments is 10% higher than that by the dental appliance with non-textured diaphragm without attachments. Considering the two sizes of vertical attachments, the correction energy transmitted by the dental appliance with textured diaphragm with vertical attachments is 15% higher than that by the dental appliance with non-textured diaphragm with vertical attachments. The correction energy transmitted by the dental appliance with textured diaphragm with torsion attachments and the dental appliance with textured diaphragm with torsion attachments is 9% higher.

[0076] In general, the retention force and correction transfer energy of the textured diaphragm dental appliance are significantly improved compared with the traditional non-textured diaphragm dental appliance, which means that the textured diaphragm dental appliance has better wrapping and higher correction efficiency than the non-textured diaphragm dental appliance.
