Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tooth orthodontics, in particular to a dental correction system. Background Art
[0002] Orthodontic correction of teeth usually requires wearing dental devices in the mouth, such as dental braces, especially shell-shaped braces. Due to their comfort, ease of wearing and removal, and aesthetics, they are chosen by more and more people.
[0003] However, during the process of orthodontic treatment with shell-shaped braces, patients will inevitably suffer from oral health problems, such as oral ulcers, periodontal disease, pulp disease, caries, oral candidiasis and other oral diseases. The occurrence of these oral diseases will make the patient's discomfort with wearing shell-shaped braces worse. If not treated in time, continuing to wear the braces may aggravate the patient's condition. Secondly, as the pain increases, the patient's discomfort becomes more and more severe. In severe cases, the patient will find it unbearable and have to stop wearing the braces and choose to correct the oral disease. This will not only extend the correction period, but also cause the patient's subsequent resistance to dental correction, which is not conducive to the subsequent correction.
[0004] That is to say, during the current treatment process of patients using shell-shaped braces for tooth correction, when patients have the above-mentioned oral health problems, in order to avoid patients having strong discomfort and causing resistance to subsequent correction, doctors often recommend that patients stop wearing the braces and treat the oral disease first, and then continue to wear the braces for correction after the oral disease is cured. In other words, teeth will not be corrected at the same time during the treatment of the oral disease. This treatment plan will obviously prolong the patient's correction cycle, especially in the case of some oral diseases that are prone to recurrence. Repeatedly stopping dental correction to treat oral diseases will seriously affect the progress of dental treatment. Moreover, stopping the wearing of the braces during the correction process will easily lead to a rebound in the current treatment results, affecting the treatment effect, and ultimately inevitably affecting the overall correction process.

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will elaborate on each embodiment of the present application with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that in each embodiment of the present application, many technical details are provided to help readers better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can still be implemented. The division of the following embodiments is for convenience of description and should not constitute any limitation on the specific implementation manner of the present application. The various embodiments can be combined and cross-referenced with each other on the premise of not being contradictory.
[0028] To make the drawings concise, only the parts related to the present utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some figures, for components with the same structure or function, only one of them is schematically shown, or only one of them is labeled. In this document, "one" not only means "only this one", but also means "more than one" situation.
[0029] At the present stage, during the orthodontic treatment process in which a patient wears a shell-shaped orthodontic appliance, when the patient develops oral diseases that affect the wearing of the orthodontic appliance, the patient usually stops wearing the orthodontic appliance first to treat the oral diseases, and then continues the orthodontic treatment after the oral diseases are cured. This way of stopping wearing the orthodontic appliance midway will, firstly, inevitably affect the patient's orthodontic cycle. Especially in the case of repeated oral diseases, the orthodontic cycle will surely be prolonged. Secondly, stopping wearing the orthodontic appliance during the orthodontic process easily leads to the rebound of the current orthodontic result, affecting the orthodontic effect, and thus further prolonging the final orthodontic cycle.
[0030] In order to solve the above problems, the present utility model provides a dental orthodontic system, which includes a first dental instrument and a second dental instrument that are sequentially worn on the patient's dentition. The first dental instrument at least includes a first shell-shaped tooth orthodontic appliance. The first shell-shaped tooth orthodontic appliance has a housing with a first accommodation cavity for accommodating and positioning the patient's teeth. The second dental instrument at least includes a second shell-shaped tooth orthodontic appliance. The second shell-shaped tooth orthodontic appliance includes a housing with a second accommodation cavity for accommodating and positioning the patient's teeth. Wherein, a medicine storage part for storing medicine is provided on the housing of the first shell-shaped tooth orthodontic appliance, so as to provide a drug effect for the area to be medicated when the first shell-shaped tooth orthodontic appliance is worn on the patient's dentition. The elasticity of the housing of the first shell-shaped tooth orthodontic appliance is greater than that of the housing of the second shell-shaped tooth orthodontic appliance. That is to say, in the present application, by providing a medicine storage part for storing medicine on each first shell-shaped tooth orthodontic appliance worn first, the medicine in the medicine storage part can be slowly released at a predetermined dose and speed, so that when the patient wears each first shell-shaped tooth orthodontic appliance, a corresponding drug effect can be provided for the area to be medicated at the diseased part for treatment. In this way, the patient does not need to stop tooth orthodontics while treating oral diseases, which not only realizes the treatment of oral diseases but also ensures the normal progress of the tooth orthodontic process. At the same time, in order to reduce the discomfort caused by oral diseases during the wearing of the orthodontic appliance, the present application designs the elasticity of the housing of the first shell-shaped tooth orthodontic appliance to be greater than that of the housing of the second shell-shaped tooth orthodontic appliance. Since the greater the elasticity of the orthodontic appliance, the smaller the orthodontic force on the teeth, the damage to the affected area of oral diseases caused by the shell-shaped orthodontic appliance can be minimized, thereby reducing the discomfort of the patient when wearing the orthodontic appliance in the case of oral diseases and enabling the orthodontic process to continue smoothly.
[0031] In some embodiments, in order to further reduce the discomfort of the patient when wearing the shell-shaped orthodontic appliance in the case of oral diseases, the geometric shape of the housing of each first shell-shaped tooth orthodontic appliance in the first dental instrument has a first designed movement amount, and the geometric shape of the housing of each second shell-shaped tooth orthodontic appliance in the second dental instrument has a second designed movement amount. Wherein, the first designed movement amount is less than the second designed movement amount. Generally speaking, for the same movement mode of the same tooth, the smaller the movement amount, the smaller the tooth orthodontic force required, and the relatively stronger the comfort. In the present application, by designing the first designed movement amount of the geometric shape of the housing of the first shell-shaped tooth orthodontic appliance for simultaneous treatment and orthodontics to be less than the second designed movement amount of the geometric shape of the housing of the second shell-shaped tooth orthodontic appliance only for orthodontics after the oral disease is cured, the patient is made to receive a smaller tooth orthodontic force when wearing the first shell-shaped tooth orthodontic appliance in the case of oral diseases, thereby improving the wearing comfort of the shell-shaped tooth orthodontic appliance during the treatment of oral diseases.
[0032] In some embodiments, to achieve simultaneous treatment and orthodontics when a patient has oral diseases, the drug storage part provided on the first shell-shaped tooth orthodontic appliance can be locally provided corresponding to the shell part corresponding to the area to be medicated. Designing the drug storage part locally for the area to be medicated can make the treatment more targeted and more efficient; in some embodiments, the drug storage part provided on the first shell-shaped tooth orthodontic appliance can also be provided corresponding to the patient's entire dentition. Considering that in some cases, some oral diseases such as periodontitis require medication for the entire dentition to achieve the effect, in this application, by providing the drug storage part corresponding to the patient's entire dentition, the area of drug action is expanded to facilitate the complete treatment of oral diseases.
[0033] The following will specifically describe the implementation details of the dental orthodontic system described in this application in combination with specific embodiments. The following content is only implementation details provided for convenient understanding and is not necessary for implementing this solution.
[0034] Currently, for the tooth orthodontic process, generally, a series of shell-shaped polymers are worn on the patient's dentition successively. When worn, relying on the elastic force of the shell, the tooth state (such as the position of the teeth) is gradually changed, so that the patient's dentition is gradually aligned to meet the clinical index requirements and / or the patient's own aesthetic requirements.
[0035] Specifically, for a clinical orthodontic process, depending on the different current tooth conditions of the patient, a total of 20 - 50 shell-shaped orthodontic appliances are required. The patient generally wears each shell-shaped orthodontic appliance for 1 - 2 weeks and then changes to the next one, so as to gradually correct the patient's current tooth state (i.e., the tooth state before orthodontics) to the target tooth layout relying on the elastic force of the shell-shaped orthodontic appliance. Each shell-shaped orthodontic appliance corresponds to a set of tooth orthodontic states. Specifically, the geometric shape of the first shell-shaped orthodontic appliance corresponds to the first orthodontic state (this first orthodontic state is the state of the patient's current tooth state after the first orthodontic step); and the geometric shape of the second shell-shaped orthodontic appliance corresponds to the second orthodontic state (this second orthodontic state is the state after the second orthodontic step from the first orthodontic state);... The geometric shape of the last shell-shaped orthodontic appliance corresponds to the target tooth layout (this target tooth layout is the tooth state at the end of the last orthodontic step).
[0036] As Figure 1As shown in the figure, the present utility model provides a dental orthodontic system, which includes a first dental instrument 10 and a second dental instrument 20 for wearing on the patient's dentition. The first dental instrument 10 includes M first shell-shaped tooth aligners 10i, where 1 ≤ i ≤ M, and M is a natural number greater than 1. Each first shell-shaped tooth aligner 10i has a housing with a first receiving cavity for accommodating and positioning the patient's teeth. The second dental instrument 20 includes N first shell-shaped tooth aligners 20j, where 1 ≤ j ≤ N, and N is a natural number greater than 1. Each second shell-shaped tooth aligner 20j has a housing with a second receiving cavity for accommodating and positioning the patient's teeth. That is to say, each first shell-shaped tooth aligner 10i and each second shell-shaped tooth aligner 20j have the tooth orthodontic function of moving the teeth. The first shell-shaped tooth aligners 10i of the first dental instrument 10 are used for simultaneously treating oral diseases and orthodontics when the patient has oral diseases. A medicine storage part 11 is provided on the housing of each of the first shell-shaped tooth aligners 10i, and the medicine storage part 11 stores medicines for treating corresponding oral diseases. The medicines are slowly released during the wearing process of the first shell-shaped tooth aligner 10i, so as to provide a drug treatment effect for the diseased part (i.e., the area where the drug needs to be administered), realizing the simultaneous progress of tooth orthodontics and oral disease treatment, so that the patient does not need to stop tooth orthodontics when having oral diseases, improving the overall efficiency of tooth orthodontics. The second dental instrument 20 is worn subsequently corresponding to the first dental instrument 10, that is, each second shell-shaped tooth aligner 20j is used for wearing after the oral disease is cured. The second dental instrument 20 is only used to realize the tooth orthodontic function. Among them, considering that when there is pain during the occurrence of oral diseases, the greater force applied during the wearing of the aligner will increase the harm to the diseased part and cause a strong discomfort during the wearing of the aligner. The elasticity of each first shell-shaped tooth aligner 10i of the first dental instrument 10 should be greater than that of each second shell-shaped tooth aligner 20j of the second dental instrument 20. Generally speaking, the greater the elasticity of the shell-shaped tooth aligner, the relatively smaller the orthodontic force on the teeth, and the stronger the comfort of the patient. The aligner with greater elasticity can reduce the harm of the shell-shaped aligner to the affected area of the oral disease and reduce the discomfort of the patient during the wearing of the aligner.
[0037] Due to the irregularity of teeth and the influence of the manufacturing process, the elastic forces at different positions of the shell-shaped tooth aligners obtained from the same membrane may be different. However, in the present utility model, the influence of the differences brought by the above factors is not considered. Generally, it is considered that when the elasticity of the membrane used to prepare the first shell-shaped tooth aligner is greater than the elasticity of the membrane used to prepare the second shell-shaped tooth aligner, the elasticity of the obtained first shell-shaped tooth aligner is greater than that of the second shell-shaped tooth aligner.
[0038] That is to say, regardless of the differences brought about by the preparation process, the greater the elasticity of the diaphragm, the greater the elasticity of the prepared shell-shaped tooth orthodontic appliance, and the smaller its deformation stress (orthodontic force), resulting in a smaller movement rate and amount of movement of the teeth, and the more comfortable it is for the patient to wear. Therefore, in some embodiments, by selecting diaphragms with different elasticities, the housing of the first shell-shaped tooth orthodontic appliance used for both orthodontics and treatment can have greater elasticity to make the patient wear more comfortably, reduce the harm of the shell-shaped orthodontic appliance to the affected area of oral diseases, and facilitate the smooth progress of the orthodontic process.
[0039] The elasticity of the diaphragm is closely related to the thickness and material of the diaphragm. First, when the diaphragm thickness is the same, the greater the elastic modulus of the diaphragm material, the smaller the elasticity of the diaphragm, and the smaller the elasticity of the prepared shell-shaped tooth orthodontic appliance, and the greater the generated tooth orthodontic force. Therefore, in some examples, to make the elasticity of the housing of the first shell-shaped tooth orthodontic appliance 10i greater than that of the housing of the second shell-shaped tooth orthodontic appliance 20j, the diaphragms used to prepare each first shell-shaped tooth orthodontic appliance 10i have the same thickness as the diaphragms used to prepare each second shell-shaped tooth orthodontic appliance 20j, but the elastic modulus of the diaphragm material used to prepare each first shell-shaped tooth orthodontic appliance 10i is less than the elastic modulus of the diaphragm material used to prepare each second shell-shaped tooth orthodontic appliance 20j, so that the elasticity of the housing of each prepared first shell-shaped tooth orthodontic appliance 10i is greater than the elasticity of the housing of each second shell-shaped tooth orthodontic appliance 20j, as Figure 2 shown. Among them, the polymer material for preparing each housing can be one or a combination of several materials such as PETG (polyester), PC (polycarbonate), TPU (polyurethane), etc., or can be one or more of amorphous thermoplastic polymers, semi-crystalline thermoplastic polymers, and transparent thermoplastic polymers. The above thermoplastic polymers are selected from polycarbonate, thermoplastic polyurethane, acrylic acid, polysulfone, polypropylene, polypropylene / ethylene copolymer, cycloolefin polymer / copolymer, poly-4-methyl-1-pentene or polyester / polycarbonate copolymer, styrene-based polymer materials, polyamide, polymethylpentene, polyetheretherketone, and their combinations.
[0040] Secondly, when the diaphragm materials are the same, the size of the diaphragm thickness also determines the size of the diaphragm elasticity, that is, when the diaphragm materials are the same, the thinner the diaphragm, the greater the elasticity of the diaphragm, and the greater the elasticity of the prepared shell-shaped orthodontic appliance, and the more comfortable it is to wear. Therefore, in some other examples, to make the elasticity of the housing of the first shell-shaped tooth orthodontic appliance 10i greater than that of the housing of the second shell-shaped tooth orthodontic appliance 20j, the diaphragms used to prepare each first shell-shaped tooth orthodontic appliance 10i can have the same material as the diaphragms used to prepare each second shell-shaped tooth orthodontic appliance 20j, but the diaphragm thickness of the diaphragms used to prepare each first shell-shaped tooth orthodontic appliance 10i is less than the diaphragm thickness of the diaphragms used to prepare each second shell-shaped tooth orthodontic appliance 20j, as Figure 3As shown, the elasticity of the housing of each first shell-shaped tooth aligner 10i prepared is greater than that of the housing of each second shell-shaped tooth aligner 20j. Of course, since both the thickness and the material affect the elasticity of the diaphragm, in some specific embodiments, when the elastic modulus of the material of the diaphragm used to prepare each first shell-shaped tooth aligner 10i is less than the elastic modulus of the material of the diaphragm used to prepare each second shell-shaped tooth aligner 20j, the diaphragm thickness of the diaphragm used to prepare each first shell-shaped tooth aligner 10i may also be greater than the diaphragm thickness of the diaphragm used to prepare each second shell-shaped tooth aligner 20j; or, when the diaphragm thickness of the diaphragm used to prepare each first shell-shaped tooth aligner 10i is less than the thickness of the diaphragm used to prepare each second shell-shaped tooth aligner 20j, the elastic modulus of the diaphragm used to prepare each first shell-shaped tooth aligner 10i may also be greater than the elastic modulus of the material of the diaphragm used to prepare each second shell-shaped tooth aligner 20j, as long as the overall elasticity of the diaphragm used to prepare each first shell-shaped tooth aligner 10i including the corresponding diaphragm thickness and elastic modulus is greater than the overall elasticity of the diaphragm used to prepare each first shell-shaped tooth aligner 10i.
[0041] The elasticity of the shell-shaped tooth aligner is related not only to the elasticity of the diaphragm used to prepare the shell-shaped aligner, but also for the case of preparing the shell-shaped tooth aligner with the same diaphragm, the elasticity of the final shell-shaped tooth aligner can be changed by optimizing the diaphragm or the prepared shell-shaped tooth aligner or by changing the attachment settings on the shell-shaped tooth aligner.
[0042] Various pre-treatments or post-treatments (collectively referred to as optimization treatments) on the diaphragm used to prepare the shell-shaped tooth aligner or the prepared shell-shaped tooth aligner will cause a change in elasticity. Therefore, the elasticity can be changed by optimizing the diaphragm used to prepare the shell-shaped tooth aligner or the shell-shaped tooth aligner. For example, when the shell-shaped tooth aligner is soaked in artificial saliva for two weeks, its maximum stress and elastic modulus will increase (elasticity becomes smaller). Thus, in some examples, diaphragms with the same elasticity can be used to prepare each first shell-shaped tooth aligner 10i and each second shell-shaped tooth aligner 20j, and then each second shell-shaped tooth aligner 20j is optimized (such as soaked in artificial saliva) to make its elasticity smaller, or the diaphragm used to prepare the second shell-shaped tooth aligner is first optimized (such as soaked in artificial saliva) to make its elasticity smaller, and then each second shell-shaped tooth aligner 20j is prepared.
[0043] The type and shape of the attachments on the shell-shaped dental appliance can also cause changes in its elasticity. The attachments mentioned here can be various attachments, such as at least one of the depressions, small holes, openings, and / or protrusions on the appliance. For example, an opening on the side wall of the shell-shaped dental appliance can cause relatively small elastic deformation in the use state. Therefore, in some other examples, diaphragms with the same elasticity can be used to prepare each first shell-shaped dental appliance 10i and each second shell-shaped dental appliance 20j, and then the elasticity of each first shell-shaped dental appliance 10i or each second shell-shaped dental appliance 20j can be changed by attachment settings, so that the elasticity of each first shell-shaped dental appliance 10i is greater than the elasticity of each second shell-shaped dental appliance 20j.
[0044] The above two ways of changing the elasticity of the shell-shaped dental appliance enable the use of diaphragms with the same elasticity to prepare the first shell-shaped dental appliance and the second shell-shaped dental appliance, without the need to deliberately distinguish the diaphragms when preparing the first shell-shaped dental appliance and the second shell-shaped dental appliance, improving efficiency and reducing costs.
[0045] In some embodiments, the elasticity of the shell of each first shell-shaped dental appliance 10i in the first dental instrument 10 can gradually decrease with the wearing order of the appliances, but the elasticity of the shell of the first shell-shaped dental appliance 10i with the smallest elasticity is still less than the elasticity of the shell of the second shell-shaped dental appliance 20j in the second dental instrument 20. Specifically, the elasticity of the first shell-shaped dental appliance in the previous orthodontic step should be greater than the elasticity of the first shell-shaped dental appliance in the subsequent orthodontic step. This is because at the initial stage of oral disease treatment, the patient's pain is the strongest. At this time, the elasticity of the first shell-shaped dental appliance should be increased as much as possible to reduce the orthodontic force on the teeth and make it comfortable to wear, reducing the harm of the shell-shaped appliance to the affected area of the oral disease. With the release of the drug from the medicine storage part of the first shell-shaped dental appliance, the oral disease gradually alleviates, and the patient can gradually bear a greater orthodontic force. Therefore, the elasticity of the shell of each first shell-shaped dental appliance 10i can be gradually reduced to increase the orthodontic force, thereby accelerating the orthodontic process; in some embodiments, the elasticity of the shell of each first shell-shaped dental appliance 10i in the first dental instrument 10 can also be the same, maintaining the same elasticity of each first shell-shaped dental appliance 10i during the oral disease treatment stage. On the one hand, diaphragms with the same elasticity can be used to prepare each first shell-shaped dental appliance 10i, simplifying the preparation process and reducing costs. On the other hand, it is also unnecessary for the patient to constantly adapt to the discomfort brought by the elastic change of the shell during the oral disease treatment.
[0046] In some embodiments, considering that in some cases, the pain in the diseased area in the patient's oral cavity is generally the most intense, the damage to the diseased area caused by the shell-shaped dental appliance should be minimized. The elastic modulus of the shell part corresponding to the diseased area (i.e., the area where the drug needs to be administered) of each first shell-shaped dental appliance is greater than that of the other parts of the shell. This difference in elasticity can also be caused by at least one difference in the thickness of the diaphragm for preparing the appliance, the elastic modulus of the material, the optimization treatment method, and the accessory setting. In this case, the elastic modulus of the other parts of the shell of each first shell-shaped dental appliance except the part corresponding to the diseased area can be the same as that of each second shell-shaped dental appliance. At this time, since the elastic modulus of the shell part corresponding to the diseased area of each first shell-shaped dental appliance is greater, the overall elastic modulus of each first shell-shaped dental appliance is still greater than that of each second shell-shaped dental appliance. Of course, the elastic modulus of the other parts of the shell of each first shell-shaped dental appliance except the part corresponding to the diseased area can also be greater than that of each second shell-shaped dental appliance. At this time, the overall elastic modulus of each first shell-shaped dental appliance is obviously greater, and the patient will feel more comfortable when wearing it.
[0047] Regarding each second shell-shaped dental appliance 20j in the second dental instrument 20, since each second shell-shaped dental appliance 20j is used for the patient to wear after the oral disease is cured, and at this time the patient no longer has the pain caused by the oral disease. To ensure the smooth progress of the orthodontic treatment, the shell of the second shell-shaped dental appliance 20j can generate a greater orthodontic force. Therefore, the elastic modulus of the shell of each second shell-shaped dental appliance 20j should be less than that of each first shell-shaped dental appliance 10i, so as to ensure the smooth completion of the orthodontic treatment. Further, when the elastic modulus of each first shell-shaped dental appliance 10i is the same, the elastic modulus of the shell of each second shell-shaped dental appliance 20j is less than that of any one of the first shell-shaped dental appliances 10i. When the elastic modulus of the shell of each first shell-shaped dental appliance 10i gradually decreases with the wearing order of the appliance, the elastic modulus of the shell of each second shell-shaped dental appliance 20j needs to be less than that of the first shell-shaped dental appliance 10i with the smallest elastic modulus among each first shell-shaped dental appliance 10i.
[0048] In some embodiments, the elasticity of the housing of each second shell-shaped dental appliance 20j in the second dental appliance 20 may gradually decrease with the wearing order of the appliances. That is to say, in the initial stage after the oral disease is treated, the elasticity of the second shell-shaped dental appliance worn by the patient is still relatively large, so as to avoid applying too large a dental correction force to the teeth in the initial stage of the recovery of the oral disease and causing the recurrence of the disease. Therefore, by designing the elasticity of the housing of each second shell-shaped dental appliance 20j to gradually decrease with the wearing order, the teeth do not immediately bear a large dental correction force in the initial stage of the recovery of the oral disease. The patient can gradually adapt to the increase in the dental correction force, improving the patient's comfort and facilitating the gradual progress of the correction process. In other embodiments, considering that the patient's oral disease has recovered and the patient has no pain at this time and can actually bear a large dental correction force, the elasticity of the housing of each second shell-shaped dental appliance 20j in the second dental appliance 20 may also be the same, so that a large dental correction force can be generated when the patient wears each second shell-shaped dental appliance 20j. The continuous large dental correction force facilitates accelerating the subsequent dental correction process.
[0049] Of course, the changes in the elasticity of the shell-shaped dental appliances in the first dental appliance and the second dental appliance in the above embodiments may also be caused by at least one difference in the thickness of the diaphragm for preparing the shell-shaped appliance, the elastic modulus of the diaphragm material, the optimization treatment method of the diaphragm or the shell-shaped appliance, and the accessory setting. For details, reference may be made to the description of the elasticity change in the foregoing embodiments and will not be elaborated here.
[0050] For the orthodontics of teeth, each tooth may need to undergo various tooth movement methods. Generally, the tooth movement methods include: overall movement, rotation, torque, uprighting, extrusion, and intrusion of the tooth. Generally speaking, for the same tooth movement method of the same tooth, the smaller the movement amount, the smaller the orthodontic force required for the tooth, and the relatively stronger the comfort of the patient. Therefore, in some embodiments, in order to further reduce the discomfort of the patient wearing the first shell-shaped tooth orthodontic appliance, each first shell-shaped tooth orthodontic appliance 10i has a relatively small designed movement amount, so as to cause a relatively small tooth movement amount when the patient wears the first shell-shaped tooth orthodontic appliance. Specifically, the geometric shape of the housing of each first shell-shaped tooth orthodontic appliance 10i in the first dental appliance 10 has a first designed movement amount for generating a first tooth movement amount that causes tooth movement. The geometric shape of the housing of each second shell-shaped tooth orthodontic appliance 20j in the second dental appliance 20 has a second designed movement amount for generating a second tooth movement amount that causes tooth movement. Among them, the first designed movement amount is less than the second designed movement amount, that is, the tooth movement amount generated when the patient wears the first shell-shaped tooth orthodontic appliance 10i is less than the tooth movement amount generated when the patient wears the second shell-shaped tooth orthodontic appliance 10i. It should be noted that the first designed movement amount and the second designed movement amount of the housing being compared here are single-step designed movement amounts designed for the same tooth movement method of the same tooth at different orthodontic stages. For example, for the orthodontics of the current patient's teeth, tooth No. 3 needs to be twisted, and the single-step designed movement amount of the twisting angle is 1 to 3 degrees. Then, for the first shell-shaped tooth orthodontic appliance 10i, the geometric shape of the housing of tooth No. 3 has a first designed movement amount of 1 degree for the twisting angle, and for the second shell-shaped tooth orthodontic appliance 20j, the geometric shape of the housing of tooth No. 3 has a second designed movement amount of 3 degrees for the twisting angle. Thus, the housing of tooth No. 3 of the first shell-shaped tooth orthodontic appliance 10i generates a relatively small orthodontic force for twisting the tooth when worn, while the housing of tooth No. 3 of the second shell-shaped tooth orthodontic appliance 20j generates a relatively large orthodontic force for twisting the tooth when worn, reducing the tooth orthodontic force of the first shell-shaped tooth orthodontic appliance during the synchronous stage of treatment and orthodontics, and improving the comfort of the patient when wearing the first shell-shaped tooth orthodontic appliance for synchronous treatment and orthodontics.
[0051] In some preferred embodiments, the geometric shapes of the shells of the first shell-shaped dental appliances 10i in the first dental appliance 10 have the same first designed movement amount. Similarly, the same first designed movement amount here also refers to the same movement mode of the same tooth. The same first designed movement amount facilitates the design of the orthodontic steps on one hand, and can achieve relatively stable orthodontic force on the other hand, improving the comfort of the patient. In other preferred embodiments, the first designed movement amount of the geometric shapes of the shells of the first shell-shaped dental appliances 10i in the first dental appliance 10 can gradually increase according to the wearing order. The purpose of such a design is that in this application, a smaller first designed movement amount can be designed for the geometric shape of the shell of the first shell-shaped dental appliance worn in the initial stage with relatively severe oral disease pain to generate a smaller orthodontic force, making it more comfortable for the patient to wear the shell-shaped appliance. As the treatment continues, the pain gradually weakens and then the first designed movement amount of the geometric shape of the shell of the first shell-shaped dental appliance is gradually increased to gradually increase the orthodontic force, enabling the patient to gradually adapt to the gradually increasing orthodontic force, which not only improves the comfort of the orthodontic process to the greatest extent but also improves the efficiency of orthodontics to a certain extent.
[0052] It should be noted that each of the first shell-shaped dental appliances 10i and each of the first shell-shaped dental appliances 20j in the first dental appliance of each embodiment of the present invention may include only the maxillary dentition, or only the mandibular dentition, or both the maxillary dentition and the mandibular dentition. This is determined according to the actual orthodontic needs and will not be elaborated here.
[0053] The structure of the medicine storage part 11 of the present invention will be specifically described through each embodiment below. It should be noted that the structures of the storage parts 11 in the following embodiments can be arbitrarily combined with the above embodiments according to the actual situation:
[0054] In some embodiments, the medicine storage part 11 can be integrally arranged for the housing of each first shell-shaped tooth aligner 10i corresponding to the entire dentition of the patient. Among them, the medicine storage part 11 is a medicine storage layer made of an adsorbable material, and the adsorbable material has the property of adsorbing medicine. In some preferred embodiments, each first shell-shaped tooth aligner 10i is a multi-layer aligner prepared from a multi-layer membrane. In some examples, when preparing the multi-layer membrane, at least one layer of the membrane can be made to adsorb medicine. For example, at least one layer of polymer material is selected as a polymer material that can adsorb medicine. For example, the material that can adsorb medicine can be selected as an adsorption resin. Adsorption resin is a kind of porous, highly cross-linked polymer copolymer. This kind of polymer material has a large specific surface area and appropriate pore size, and can adsorb certain substances from the gas phase or solution. The polymer materials that can be used as adsorption resins include polystyrene, polymethacrylic acid-ethylenedimethacrylate cross-linked body, polyvinyl alcohol, polyacrylamide, polyamide, polyethyleneimine, cellulose derivatives, etc. Adsorb the corresponding medicine on this layer of polymer to form a multi-layer membrane. Specifically, taking the first shell-shaped tooth aligner 10i with a two-layer structure as an example, the housing of each first shell-shaped tooth aligner 10i at least includes an inner layer 10i-1 and an outer layer 10i-2. Among them, the inner layer 10i-1 refers to the layer adjacent to the teeth when worn, and the outer layer 10i-2 refers to the layer far from the teeth when worn. The medicine 12 can be stored in the outer layer 10i-2 to form the medicine storage part, as Figure 4 shown. Of course, the medicine 12 can also be stored in the inner layer 10i-1 to form the medicine storage part, as Figure 5 shown. This medicine can be released after the first shell-shaped tooth aligner 10i is worn on the user's teeth, so as to achieve the purpose of treating oral diseases. Of course, each first shell-shaped tooth aligner 10i can also have a three-layer or more structure, and the medicine can also be stored in any intermediate layer to form the medicine storage part. In other examples, the housing of the first shell-shaped tooth aligner can also be formed by thermoforming technology first. When the medicine storage layer is the outer layer or the inner layer, the first shell-shaped tooth aligner can be immersed in the medicine solution so that the polymer material of the layer used to store the medicine fully adsorbs the medicine, thereby realizing the function of medicine storage; when the medicine storage layer is the intermediate layer, the medicine can be injected into the intermediate layer to realize the function of medicine storage.
[0055] In the above embodiments, the medicine is directly adsorbed on one layer of the multi-layer structure to form a medicine storage layer, and it is integrally arranged corresponding to the entire dentition, so that the area where the medicine acts corresponds to the entire dentition, which is convenient for the thorough treatment of oral diseases.
[0056] In some other preferred embodiments, the drug may also be present in a certain carrier. Common carriers include semi-solid materials such as gels. Therefore, the drug storage part 11 can also be formed by applying a carrier storing the drug in the form of a semi-solid material on the surface of the shell of the first shell-shaped tooth aligner by spraying or painting to form a coating or film. Since the thickness of such a coating or film is very thin, it can be applied on the inner surface of each first shell-shaped tooth aligner shell or on the outer surface of each first shell-shaped tooth aligner shell. The drug storage part 11 formed in this way has a simple shape, and the drug can directly contact the oral tissue, resulting in a fast treatment speed.
[0057] For some oral diseases, such as oral ulcers, dental caries, etc., local treatment of the diseased area is often required. Therefore, in some preferred embodiments, by storing the drug (such drugs include, for example, traditional Chinese patent medicines for clearing heat and anti-inflammatory drugs, etc.) on the shell corresponding to the diseased area, the drug can be slowly released for the diseased area, reducing the drug usage amount and having a higher treatment efficiency. For example, when an oral disease occurs in some specific teeth, the drug storage part 11 can be provided only for the shell part corresponding to the specific teeth. In some examples, a multi-layer structure can be formed only for the shell part corresponding to the specific teeth, and the drug storage part 11 is formed in at least one of the outer layer, inner layer, and middle layer of the multi-layer structure, while the shells corresponding to other teeth can be a conventional single-layer structure; or the drug is dissolved in a semi-solid or liquid carrier, and then the semi-solid or liquid carrier is applied to the surface of the shell corresponding to the specific teeth by spraying to form a coating or film, thereby forming the drug storage part 11.
[0058] Of course, in addition to providing the drug storage part 11 for the entire shell (not the entire dental arch) of the tooth corresponding to the diseased area, the drug storage part 11 can also be provided only for the diseased area to further reduce the drug usage amount and improve the treatment efficiency. In some examples, the drug storage part 11 includes a drug storage chamber 110 formed by local outward protrusion of the first accommodation chamber corresponding to the diseased area (i.e., the area to be medicated) in the first shell-shaped tooth aligner 10i and the drug 111 provided in the drug storage chamber 110, that is, the drug storage chamber 110 is integrally formed with the first shell-shaped tooth aligner, and the drug 111 is provided in the drug storage chamber 110. As Figure 6 shown, at this time, the drug 111 (for example, it can be a pill or a tablet) is fixed in the drug storage chamber 110, and the side of the drug storage chamber 110 facing the tooth is an opening. The drug 111 can be directly and slowly released to the diseased area through the opening. The drug 111 can release a larger dose directly through the opening, improving the treatment speed of oral diseases. Of course, a slow-release layer 112 can also be provided on the side of the drug storage chamber facing the tooth. As Figure 7As shown, the sustained-release layer 112 can not only confine the drug 111 in the storage bin, but also slowly release the drug 111 to the diseased part through the pores or mesh structure. Further, releasing the drug through the sustained-release layer 112 can reduce the rate of drug release, increase the action time of the drug in the oral cavity, and achieve better therapeutic effect. In other examples, the drug storage bin 110 of the drug storage portion 11 is separately formed from the corresponding first accommodating cavity, that is, a drug storage bin 110 for accommodating the drug 111 is first formed, and then the storage bin 110 is installed on the outer surface of the corresponding first accommodating cavity, such as Figure 8 As shown, at this time, the drug storage bin 110 is provided with a sustained-release channel 113 to facilitate the slow release of the drug in the drug storage bin 110 to the oral environment. The sustained-release channel can be an air hole provided on the drug storage bin. In some preferred examples, the air hole is provided on the side where the drug storage bin 110 is connected to the first accommodating cavity. Corresponding to the air hole on the drug storage bin 111, the first accommodating cavity is provided with corresponding air holes to connect the drug storage bin 110 with one side of the inner surface of the first accommodating cavity. The drug 111 can be slowly released through the sustained-release channel to act on the diseased part. The slow release of the drug through the sustained-release channel can also increase the action time of the drug in the oral cavity and improve the therapeutic effect.
[0059] Considering that in some cases, such as gingivitis, the drug is preferably applied directly to the gums or the corresponding position of the gums, therefore, in some embodiments, the first receiving cavity of the first shell-shaped dental appliance 10i includes at least one tooth receiving cavity 10ia and a gum receiving cavity 10ib, such as Figure 9 As shown, the tooth receiving cavity 10ia is used to receive the patient's clinical crown 10ic, and the gum receiving cavity 10ib is used to receive the gum soft tissue 10id. The drug storage part 11 can be formed on the tooth receiving cavity 10ia or on the gum receiving cavity 10ib as needed, or both the tooth receiving cavity 10ia and the gum receiving cavity 10ib are provided with a drug storage part 11. The utility model does not make any limitation. As for the specific structural form of the drug storage part 11, reference can be made to the aforementioned embodiments, which will not be described in detail here. In this embodiment, by including the first accommodating cavity in the gum receiving cavity, when the gum needs to be treated with medication, the medication can be targeted at the gum area where medication is required, or the gum can be treated as a whole, which can provide more targeted medication for the affected area and the gum area, thereby improving the treatment efficiency.
[0060] Those skilled in the art will appreciate that the above embodiments are specific embodiments for implementing the present application, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present application.
