Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, and in particular to a magnetic invisible aligner for treating posterior open bite. Background Technology

[0002] Posterior open bite is a common malocclusion, typically characterized by the inability of the posterior teeth to make normal contact when the upper and lower teeth are closed. This can affect aesthetics and chewing function, and in severe cases, even impact the craniofacial structure and growth direction. Therefore, it is generally recommended to begin orthodontic treatment for malocclusion as early as possible, especially during childhood growth and development. Posterior open bite caused by poor oral habits should be promptly addressed to maximize the establishment of a harmonious oral-maxillofacial environment for development.

[0003] Existing orthodontic appliances are mainly divided into two types based on their fixation method, purpose, and design features. Whether fixed or removable, they aim to improve tooth alignment and jaw growth direction by guiding and adjusting the interaction between facial muscles, jawbone, and teeth. They utilize the muscle function, biting force, and natural growth potential of patients in the growth and development stage of children or adolescents to promote the normal development of jawbone and teeth, thereby correcting malocclusion.

[0004] However, the treatment of posterior open bite using fixed orthodontic appliances has a long overall treatment cycle. The brackets and wires make cleaning teeth more difficult, easily accumulating plaque and food debris. This can lead to enamel demineralization, affecting dental health and aesthetics, and increasing the risk of cavities, gingivitis, and other oral diseases, especially in children and adolescents. Therefore, traditional removable functional appliances are not suitable for posterior open bite treatment as they cannot guarantee good results. However, ordinary clear aligners are only suitable for patients with mild open bite. For moderate to severe cases, the effect of clear aligners alone is limited, and comprehensive treatment usually requires combination with other orthodontic devices (such as traditional fixed appliances) or surgery.

[0005] Therefore, it is crucial to provide an orthodontic appliance that can solve the above problems. Utility Model Content

[0006] In order to solve the above problems, the purpose of this utility model is to provide a magnetic invisible orthodontic appliance for treating posterior open bite.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0022] The eruption cap of the second brace has a protrusion that has a shape on the side closest to the target mandibular tooth that matches the occlusal surface of the target mandibular tooth.

[0023] In one embodiment of this utility model, the first and second dental braces are provided with a first limiting member for limiting the incisors;

[0024] The first limiting member is embedded in the inner cavity of the first dental crown and the second dental crown.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] (1) Highly adjustable: By changing the polarity and distance of the magnetic components (first magnetic component and second magnetic component), the force applied to the teeth and jawbone can be precisely controlled, ensuring more precise mechanical action during treatment;

[0045] (2) Stable and long-lasting force: The magnetic force of the magnetic components (first magnetic component and second magnetic component) can continuously apply a stable force, which helps the teeth and jawbone to move in an orderly manner, reduces the adverse effects of force fluctuations, and achieves the ideal orthodontic effect.

[0046] (3) Reduced mechanical stimulation: Compared with the mechanical parts of traditional functional orthodontic appliances, the magnetic orthodontic appliances have fewer moving parts, which reduces the stimulation and discomfort to the oral soft tissues. The pressure on the oral cavity is lower when wearing them, which improves the patient's comfort.

[0047] (4) Preventing poor retention of invisible braces: The setting of the first limiting piece (for the incisors) and the second limiting piece (for the molars) can make the invisible braces fit tightly between the teeth (the setting of the limiting piece can also enhance the stability of the fit), thus avoiding poor retention or even falling off of the invisible braces.

[0048] (5) Enhance the structural strength of invisible braces: The structural strength of invisible braces is enhanced by the protrusions set around the first magnetic component, so that invisible braces can provide more durable orthodontic force to the target teeth and ensure the orthodontic effect.

[0126] Example 6

[0127] This embodiment provides a method for wearing a magnetic invisible aligner (Example 5) for treating posterior open bite, as detailed below:

[0128] Holding the first dental crown, align the first dental crown with the upper teeth one by one, and slowly press the middle of the first dental crown. At this time, due to the pushing force, the incisor slowly enters the first dental crown and enters the first elastic piece. Due to the elasticity of the first waist 62, the first limiting piece 63 and the second limiting piece 64 deform. At the same time, the first waist 62 expands outward, so that the incisor is locked. Then the first waist 62 releases the elastic force to limit the position of the incisor.

[0129] Slowly press both ends of the first dental brace. At this time, due to the pushing force, the molar slowly gets stuck in the first dental brace and enters the second elastic piece. Due to the elasticity of the second waist 72, the third limiting piece 73 and the fourth limiting piece 74 deform. At the same time, the second waist 72 expands outward, so that the molar is stuck. Then the second waist 72 releases the elastic force to limit the position of the molar.

[0130] In the above process, it is also necessary to ensure that the first dental crown is fitted on the outer surface of the retention attachment 4, and that the first magnetic element 31, which is set on the inner cavity of the eruption cap 2 on the first dental crown, and the second magnetic element 32, which is set on the occlusal surface of the maxillary target tooth, are attracted to each other, and the protrusion 5 is in contact with the occlusal surface of the maxillary target tooth.

[0131] Holding the second dental crown, align the second dental crown with the mandibular teeth one by one, and slowly press the middle of the second dental crown. At this time, due to the pushing force, the incisor slowly enters the first dental crown and enters the first elastic piece. Due to the elasticity of the first waist 62, the first limiting piece 63 and the second limiting piece 64 deform. At the same time, the first waist 62 expands outward, so that the incisor is locked. Then the first waist 62 releases the elastic force to limit the position of the incisor.

[0132] Slowly press both ends of the second dental bracket. At this time, due to the pushing force, the molar slowly gets stuck in the second dental bracket and enters the second elastic plate. Due to the elasticity of the second waist 72, the third limiting plate 73 and the fourth limiting plate 74 deform. At the same time, the second waist 72 expands outward, so that the molar is stuck. Then the second waist 72 releases the elastic force to limit the position of the molar.

[0133] During the above process, it is also necessary to ensure that the second dental crown is fitted on the outer surface of the retention attachment 4, and that the first magnetic element 31, which is set on the inner cavity of the eruption cap 2 on the second dental crown, and the second magnetic element 32, which is set on the occlusal surface of the mandibular target tooth, are attracted to each other, and the protrusion 5 is in contact with the occlusal surface of the mandibular target tooth.

It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort.
