Description

Technical Field

[0001] This utility model relates to the technical field of maxillary orthodontic devices, and in particular to a removable orthodontic appliance. Background Technology

[0002] Anterior crossbite, also known as underbite, is a common malocclusion in children in my country. It is characterized by abnormal tooth relationships, jawbone development and craniofacial relationships, dysfunction of the stomatognathic system, and incoordination of masticatory muscles, resulting in reduced masticatory efficiency. It has a significant impact on oral function, facial aesthetics, and mental health, and the symptoms gradually worsen with age.

[0003] Currently, orthodontic appliances are mainly used in clinical practice. For example, a modified functional appliance for underbite disclosed in Chinese Patent Publication No. CN217488901U is based on the principle of mechanics in physics. By applying appropriate external force to the teeth, it gradually moves them to the correct position, thereby achieving the purpose of correcting the teeth. The mechanism of action of removable orthodontic appliances is as follows: 1. Applying external force to the teeth. 2. Under the action of the external force of the appliance, the teeth and surrounding periodontal tissues undergo adaptive changes, and the teeth gradually move to the new position. During this process, the cells in the periodontal tissues proliferate and remodel to adapt to the new position of the teeth.

[0004] During the correction of an underbite, if a child has bad habits such as sticking out their tongue, licking their teeth, sucking their fingers, or primary tongue thrusting, these bad habits will affect the correction effect.

[0005] Therefore, it is essential to provide a removable orthodontic appliance to address the shortcomings of existing technologies. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a removable orthodontic appliance. This removable orthodontic appliance can prevent the bad habit of protruding the tongue, thereby improving the correction effect of underbite.

[0027] The technical solution of this utility model will be further explained with reference to the following embodiments.

[0028] Example 1

[0029] A type of removable orthodontic appliance, such as Figure 1 and Figure 2 As shown, the device includes a base 100, a hyperbolic lingual spring 200 for exerting force on the incisors, a retention device 300 fixed to the molars, and a tongue rail 400 that abuts against the tongue 500 to prevent the tongue 500 from protruding forward. The hyperbolic lingual spring 200, retention device 300, and tongue rail 400 are all fixedly assembled to the base 100. The tongue rail 400 is located on the lingual side of the incisors and behind the hyperbolic lingual spring 200.

[0030] It should be noted that the tongue rail 400 of this invention forms an area of ​​contact with the tongue 500 inside the oral cavity, preventing the tongue 500 from unintentionally protruding forward, thereby avoiding bad habits such as tongue protrusion, teeth licking, finger sucking, and primary tongue thrusting. When the user needs to speak or protrude the tongue 500, they only need to actively move the tongue 500 across the tongue rail 400 for normal movement. "Unintentionally protruding forward" in this context refers to the direction in which the tongue 500 extends from the incisors.

[0031] One end of the tongue rail 400 is fixedly fitted inside the base 100, and the other end of the tongue rail 400 is located outside the base 100.

[0032] Multiple tongue rails 400 are provided, and each tongue rail 400 is a symmetrical structure formed by bending a steel wire, with both ends of the steel wire fixedly embedded inside the base 100, such as... Figure 3 and Figure 4 .

[0033] It should be noted that the number of tongue rails 400 in this removable orthodontic appliance can be set to 2, 3, 5, etc., depending on the actual situation. This embodiment is illustrated by setting 4 tongue rails 400. It should also be noted that each tongue rail 400 is formed by bending a steel wire to create a smooth tongue rail 400, protecting the tongue 500 from injury.

[0034] The two ends of the steel wire are circular arc structures 410, and the central angle of the circular arc structure 410 is defined as A, where 250°≤A≤300°.

[0035] It should be noted that, due to the long-term contact with the tongue 500 and the relatively strong force of the tongue 500, the function of the arc structure 410 is to improve the stability of the tongue rail 400 on the base 100. The arc structure 410 can also be hooked with adjacent tongue rails 400 or hyperboloid tongue springs 200 and retention devices 300, thereby further improving the stability of the tongue rail 400 and increasing the service life of the removable orthodontic appliance.

[0036] The portion of the tongue rail 400 embedded inside the base 100 is defined as the embedment end 430, and the portion outside the base 100 is defined as the tongue rail end 420. The tongue rail end 420 is provided with two vertical segments 440 and one horizontal segment 450. The two ends of the horizontal segment 450 are integrally connected to one end of each vertical segment 440, and the other end of each vertical segment 440 is integrally connected to the embedment end 430; the two vertical segments 440 are parallel to each other.

[0037] The removable orthodontic appliance is held inside the oral cavity by the retention device 300. The double-curved tongue spring 200 acts on the incisors, and the tongue rail 400 forms a contact area with the tongue 500, preventing the tongue 500 from inadvertently protruding forward. This avoids bad habits such as tongue protrusion, teeth licking, thumb sucking, and primary tongue thrusting, thereby improving the correction effect of underbite.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
