Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and more specifically to a device for correcting mesial tilted mandibular second molars. Background Art

[0002] Incomplete molar eruption is a common malocclusion in the oral field. It often occurs in the mandibular second molar, and is characterized by mesial inclination of the second molar accompanied by incomplete eruption. Epidemiological data show that in the general population, the incidence of mesial impaction of the second molar is between 0.06% and 0.3%. Its main cause may be closely related to the abnormal eruption of teeth. This malocclusion not only directly has an adverse effect on the chewing function and reduces the chewing efficiency, but may also cause abnormalities in the adjacent surfaces between the affected teeth and the adjacent teeth, which may further lead to a series of oral health problems such as food impaction, local periodontitis, and caries. In severe cases, it may even cause tooth loss.

[0003] The current treatment strategy faces many challenges. The usual treatment methods are restorative treatment and orthodontic treatment. For slightly tilted and slightly impacted teeth, crown restoration can change the abnormal crown direction, but this method usually requires a large amount of reduction of originally healthy tooth tissue, which will undoubtedly damage the integrity of the tooth. What is more difficult is that food residues are more likely to remain around the restoration, which not only increases the difficulty of cleaning, but also may cause food impaction, thus posing a serious threat to periodontal health. The orthodontic treatment process is restricted by many factors, such as the locking of adjacent teeth and opposing teeth, and the influence of orthodontic metal devices on patients. In general, the current orthodontic treatment for mesial tilted impacted molars still mainly relies on traditional metal fixed appliances. However, this method has problems: first, it is difficult to overcome the locking phenomenon of the opposing teeth and adjacent teeth, which greatly limits the treatment effect; second, the complexity of the device affects the patient's chewing activities such as meals; third, the correction method of implant nails is an invasive surgical treatment, and the patient's acceptance is limited. Therefore, in order to more effectively correct the tilted posterior teeth, the innovation and improvement of targeted orthodontic devices urgently need to be studied and explored. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a device for straightening the mesial tilted mandibular second molar, which has the advantages of avoiding interference between adjacent teeth and opposing teeth, having little effect on chewing and aesthetics, and requiring no surgical implantation of implant pins.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for straightening the mesial tilted mandibular second molar, comprising a tongue button, the bottom of the outer surface of the tongue button is movably connected with a boot-shaped curve, the left end of the boot-shaped curve is fixedly connected with a small circle curve, the outer surface of the boot-shaped curve is movably connected with a tooth-dividing leather ring located on the right side of the tongue button, the right end of the boot-shaped curve is fixedly connected with a wave curve, and the outer surface of the wave curve is movably mounted with a transparent pressed film occlusal plate.

[0006] As a preferred technical solution of the utility model, the tongue button is circular in shape and needs to be photocured after installation.

[0007] As a preferred technical solution of the utility model, the tooth-dividing leather ring is made of rubber material, and the tooth-dividing leather ring is embedded between the affected tooth and the adjacent tooth to loosen and release the lock.

[0008] As a preferred technical solution of the utility model, the transparent pressed film occlusal plate is wrapped around the crowns of the anchor teeth, i.e., teeth 37 to 46.

[0009] As a preferred technical solution of the utility model, the boot-shaped curve is formed by bending stainless steel wire, and its boot-shaped structure can exert force on the tilted teeth, thereby achieving an effective straightening effect.

[0010] As a preferred technical solution of the utility model, the wave curve needs to be bent according to the lip and cheek morphology of the patient's dentition before production to ensure that it fits closely with the target dentition.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model is provided with a tongue button, a tooth-dividing leather ring, a transparent pressed film bite plate and a boot-shaped curve. Compared with a conventional orthodontic appliance, the tongue button is smaller in size and more suitable for the intraoral environment. Due to the design of the boot-shaped curve, the force-applying unit of the boot-shaped curve conforms to the principle of biomechanics and can achieve an efficient straightening effect. The loosening effect of the tooth-dividing leather ring and the occlusal lifting effect of the transparent pressed film bite plate can respectively avoid interference of adjacent teeth and opposing teeth with the correction. The device can be removed when the patient eats without affecting chewing. Secondly, the device has good overall aesthetics, and has the aesthetic characteristics of an invisible orthodontic appliance and the strong biomechanical effect of a metal orthodontic appliance. Moreover, the operation is simple and convenient, and it is easier to clean and care for. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1 As shown, the utility model provides a device for straightening the mesial tilted mandibular second molar, comprising a tongue button 1, a boot-shaped curve 5 is movably connected to the bottom of the outer surface of the tongue button 1, a small circle curve 4 is fixedly connected to the left end of the boot-shaped curve 5, the outer surface of the boot-shaped curve 5 is movably connected to a tooth-dividing leather ring 2 located on the right side of the tongue button 1, the right end of the boot-shaped curve 5 is fixedly connected to a wave curve 6, and a transparent pressed film occlusal plate 3 is movably installed on the outer surface of the wave curve 6.

[0017] By setting the tongue button 1, the tongue button 1 is bonded to the buccal surface of the mesial tilted impacted molar, so that the tongue button 1 can play a role in transmitting the correction force. Due to the design of the boot-shaped curve 5, the boot-shaped curve 5 can generate a straightening force toward the distal and distal directions by restoring the deformation, and plays a role in straightening the mesial tilted molar. The design of the small circle curve 4 can prevent the rear end of the entire device from scratching the patient's oral mucosa, and at the same time can limit the working range of the boot-shaped curve 5, and prevent the boot-shaped curve 5 from accidentally falling off from the outer surface of the tongue button 1.

[0018] The tongue button 1 has a circular shape and needs to be photocured after installation.

[0019] Before bonding, the tongue button 1 needs to be etched with enamel acid to the mesial part of the buccal surface of the tilted molar in the patient's mouth to create favorable conditions for the subsequent bonding process. The tongue button 1 is installed on the inner tilted molar through an adhesive and a bonding resin.

[0020] The tooth-dividing leather ring 2 is made of rubber material, and is embedded between the affected tooth and the adjacent tooth to loosen and release the lock.

[0021] By providing the tooth-dividing leather ring 2, the mechanical locking of the tooth body outer shape of the adjacent teeth can be loosened, thereby further optimizing the correction effect and further reducing the resistance that may be encountered during the correction process.

[0022] The transparent laminated occlusal plate 3 is wrapped around the crowns of the anchor teeth, i.e., the 37th to 46th teeth.

[0023] The transparent pressed film bite plate 3 has the function of retaining and providing depression force support, which can ensure the stability and reliability of the device in the oral cavity. At the same time, it raises the posterior teeth to achieve occlusal contact between the open affected teeth and the opposing teeth, effectively eliminating the locking interference of the opposing teeth on the affected teeth.

[0024] The boot-shaped curve 5 is formed by bending stainless steel wire, and its boot-shaped structure can exert force on the tilted teeth, thereby achieving an effective straightening effect.

[0025] By providing the boot-shaped curve 5, the boot-shaped curve 5 can generate a correcting force through the deformation and rebound of the stainless steel wire, directly acting on the tilted molar, guiding it to move along the mechanical path, and gradually correcting the tilted state.

[0026] Among them, the wave curve 6 needs to be bent according to the labial and buccal morphology of the patient's dentition before production to ensure that it fits closely with the target dentition.

[0027] Due to the design of the wave curve 6, the contact area between the stainless steel wire and the transparent pressed film bite plate is increased, which prevents the stainless steel wire from rotating, plays a role in stabilizing the force, and improves the stability and reliability of the correction.

[0028] The working principle and use process of this utility model:

[0029] By setting up the transparent laminated occlusal plate 3 and the boot-shaped curve 5, a stable and efficient correction system is jointly constructed. The transparent laminated occlusal plate 3 fits tightly against the crown of the non-affected tooth to form a solid support. At the same time, the boot-shaped curve 5 generates a correction force through the deformation and rebound of the stainless steel wire, which directly acts on the tilted molar, guides it to move along the mechanical path, and gradually corrects the tilted state. Due to the design of the boot-shaped curve 5 and the tooth-dividing leather ring 2, the boot-shaped curve 5 can lift the occlusion of the non-affected tooth, and the occlusal contact between the affected tooth and the opposing tooth is cleared, effectively eliminating the locking interference of the opposing tooth on the affected tooth, and the tooth-dividing leather ring 2 is embedded between the affected tooth and the mesial adjacent tooth, and the locking of the adjacent tooth body is loosened by the elastic force of the rubber, thereby ensuring the effective application of the correction force during the entire correction process.
