Description

TECHNICAL FIELD

[0001] The utility model relates to the field of orthodontic technology, and specifically relates to a kind of invisible correction opening bite device combined with active functional appliance, for treating deep overbite or anterior occlusion deep patient, especially suitable for deep overbite correction. BACKGROUND

[0002] Deep overbite is one of the most common malocclusion in orthodontic clinic, which is characterized by excessive coverage of upper anterior teeth on lower anterior teeth. Mild deep overbite may only affect appearance, while severe deep overbite may mainly cause the following problems:

[0003] 1. Tooth wear: excessive contact of anterior teeth leads to increased wear of incisal edge, and even enamel loss.

[0004] 2. Mastication dysfunction: due to tight contact of anterior teeth, normal movement of mandible is limited, affecting mastication efficiency.

[0005] 3. Temporomandibular joint disorder (TMD): some deep overbite patients have mandibular retrusion, which causes uneven stress on the joint, causing pain, joint clicking and other problems.

[0006] 4. Risk of periodontal health: excessive overbite may affect gum health, leading to recession of anterior gum and bone loss.

[0007] The key to correcting deep overbite is to open the bite, that is, to adjust the position of teeth and jaw by appliance, so as to restore the normal occlusal relationship of upper and lower anterior teeth. The main schemes for deep overbite correction at present include invisible aligner (such as Invisalign, Times Angel) and active functional appliance (such as Twin-Block), but each has certain limitations.

[0008] The limitation of invisible aligner is that it mainly relies on Bite Ramp or rubber band, but these methods have limited effect on patients with severe deep overbite, and the correction force is insufficient. Moreover, patients need to wear it for a long time (20-22 hours per day), and the compliance requirement is high. In addition, the overcorrection design of invisible aligner may cause poor fit of the mouthpiece, affecting the treatment course.

[0009] The limitation of active functional appliance is that it is mainly suitable for children and adolescents, but has limited effect on adult patients. Moreover, it depends on the active wearing of patients, affecting appearance and comfort. And it may affect mastication function after wearing, leading to a long adaptation period.

[0010] The specific advantages and disadvantages of the prior art are shown in the following table:

[0011]

[0012] In general, the invisible aligner has problems of inaccurate mechanical control, high patient cooperation requirement, etc. in treating deep overbite. The existing method either affects the comfort and aesthetics or relies on additional devices, increasing the burden on patients. Moreover, for patients with severe deep overbite, a single invisible aligner or active functional appliance often cannot achieve the best treatment effect.

[0013] In summary, there are certain limitations in using a single invisible aligner or active functional appliance. Therefore, it is necessary to develop a new treatment method that combines the aesthetics of invisible aligners and the functionality of active functional appliances to achieve a more precise, comfortable, and adjustable occlusal opening solution. Practical new type content

[0014] The technical problem to be solved by the present utility model is to provide an occlusal opening device that can achieve a more precise, comfortable, and adjustable occlusal opening solution.

[0019] Preferably, the plane guide plate sleeve only wraps the part of the invisible aligner corresponding to the front teeth.

[0020] Preferably, the front tooth plane guide plate and the plane guide plate sleeve form an integrated structure. For example, the front tooth plane guide plate and the plane guide plate sleeve are fixed together when leaving the factory, forming an integrated structure.

[0021] Preferably, the front tooth plane guide plate has a filling cavity for accommodating self-curing plastic, and the filling cavity has an opening for adjusting the amount of self-curing plastic. In this way, the amount of self-curing plastic in the front tooth plane guide plate can be adjusted. Thus, the doctor can increase or decrease the filling amount of self-curing plastic in the filling cavity of the front tooth plane guide plate to dynamically adjust the occlusal height. Moreover, the doctor can regularly or irregularly adjust the filling material of the front tooth plane guide plate according to the treatment progress of the patient to dynamically control the occlusal opening process.

[0022] Preferably, the plane guide plate sleeve adopts a nested structure, i.e. the plane guide plate sleeve is nested to wrap the invisible aligner, thereby ensuring that the active functional appliance and the invisible aligner are firmly combined and avoiding displacement or loosening due to occlusal force.

[0023] Preferably, the shape of the anterior teeth plane guide conforms to the upper jaw anterior teeth lingual side anatomical structure, ensuring comfort during wearing and not affecting other orthodontic functions.

[0024] Preferably, the material of the anterior teeth plane guide and the plane guide sleeve is a biocompatible polymer material, improving durability and wearing comfort.

[0025] Preferably, the anterior teeth plane guide and the plane guide sleeve can be used with different brands of invisible aligners, for example, the anterior teeth plane guide and the plane guide sleeve are adapted to different types of invisible aligners.

[0026] Preferably, the invisible aligner combined with the active functional appliance opens the bite device for deep overbite correction.
