Description

Technical Field

[0001] The present invention relates to the technical field of dental correction instruments, and in particular to a longitudinal force applying device for a dental brace, and a dental brace assembly using the longitudinal force applying device. Background Art

[0002] Bracketless invisible braces are more aesthetically pleasing than the treatment method using brackets and archwires, and therefore have attracted more and more attention from orthodontic patients in recent years. Invisible braces are usually made of transparent polymer materials, which have low strength and high elasticity, resulting in the lack of invisible braces in lowering the front teeth, and the control rate of lowering the maxillary front teeth is low.

[0003] The use of anchor pins in combination with invisible braces can effectively achieve the lowering of the maxillary anterior teeth. However, the implantation of anchor pins is an invasive operation, and some orthodontic patients are unwilling or afraid to have anchor pins implanted. In order to lower the maxillary anterior teeth without using anchor pins, patent CN214511349U discloses a vertical traction device for invisible braces, which sets a limit shell on a head cap close to the front side of the human ear. When in use, the head cap is worn on the head, and the traction hook of the traction rod is hooked on the anterior area of ​​the invisible braces on the anterior teeth. The elastic component applies an upward traction force to the anterior area of ​​the invisible braces on the anterior teeth, thereby achieving the lowering of the anterior teeth.

[0004] Although this head-mounted method provides a fulcrum for applying longitudinal force to the front teeth without the need for anchor pins, the head cap and limiting shell will cover parts of the patient's head and face, which is not only inconvenient for orthodontic patients' daily life, but also unsightly, and orthodontic patients are not willing to wear it. At the same time, since some parts are located outside the mouth, they are easily tilted by collision during wearing, resulting in uneven force and limited depression effect on the front teeth. Summary of the invention

[0005] One object of the present invention is to provide a braces longitudinal force applying device, by bonding the device to the premolars or molars of an orthodontic patient, the orthodontic buckle arranged on the arch wire can be used as a traction fulcrum of the maxillary braces, and when connected to the connecting piece on the maxillary braces through a rubber band, the maxillary braces can be continuously applied with longitudinal force during the wearing process of the maxillary braces, thereby realizing the anterior teeth depression of the maxillary braces. The structure of the entire applying device is simple and beautiful, and the arch wire is located in the mouth and is not easily disturbed by external forces. It can continuously and stably apply uniform longitudinal force to the maxillary braces, effectively improving the anterior teeth depression effect.

[0006] The present invention is achieved through the following technical solutions:

[0007] A longitudinal force applying device for braces comprises an accessory and a mounting arch wire, wherein both ends of the mounting arch wire are connected to the teeth of the maxilla via the accessory, an orthodontic buckle is arranged on the mounting arch wire, and the orthodontic buckle is used to connect the maxillary braces and apply longitudinal force to the maxillary braces.

[0008] In the present technical solution, the longitudinal force applying device includes an arch wire, and the arch wire can be an existing arch wire used for dental corrections. In some preferred embodiments, the arch wire extends along the maxillary vestibule groove of the orthodontic patient, and both ends of the arch wire are bonded to the surface of the maxillary teeth through accessories. In one or more embodiments, the two ends of the arch wire can be bonded to teeth at different positions on both sides of the maxilla, for example, one end is bonded to the first molar on one side of the maxilla, and the other end is bonded to the second molar on the other side of the maxilla; the two ends of the arch wire can also be bonded to teeth at the same position on both sides of the maxilla, for example, the two ends are respectively bonded to the second premolars on both sides of the maxilla. In some embodiments, the accessories can be existing accessories used in dentistry, such as accessories formed after the light-curing resin material is cured on the tooth surface.

[0009] In the present technical solution, after the arch wire is fixedly installed and the orthodontic patient wears the maxillary braces, the accessories are located on the inner side of the maxillary braces, and the maxillary braces can be used to form a certain protective effect on the accessories, thereby improving the stability of the installation of the arch wire. At the same time, after wearing the maxillary braces, the orthodontic buckle on the arch wire is located above the maxillary braces. After the orthodontic buckle is connected to the maxillary braces by a rubber band, the orthodontic buckle provides a fulcrum for the force. Under the elastic force of the rubber band, the maxillary braces is continuously subjected to a vertical upward traction force, that is, a longitudinal force, thereby achieving the depression of the front teeth. In some preferred embodiments, the position of the orthodontic buckle is configured so that when the arch wire is fixed on the teeth, the orthodontic buckle is located near the center of the two upper front teeth, so as to better enable the maxillary braces to act on the front teeth.

[0010] In the technical solution, by fixing the mounting arch wire on the teeth and using the orthodontic buckle on the mounting arch wire as a fulcrum for traction, longitudinal force can be continuously applied to the maxillary braces during the wearing process of the maxillary braces, thereby effectively improving the effect of lowering the anterior teeth; and the entire device has a simple and compact structure, can be well set in the maxillary vestibule groove of the orthodontic patient, is not easily disturbed by external forces, and will not cause a significant impact on the appearance and image of the orthodontic patient, which is conducive to the promotion and application of the device.

[0011] As a preferred structure of the longitudinal force applying device in the present invention, the mounting arch wire includes a mounting section for mounting the orthodontic buckle, and a lifting section connected to the end of the mounting section, and the lifting section is vertically connected to the attachment.

[0012] In the present technical solution, the installation archwire includes an installation section and a lifting section. The installation section extends along the maxillary vestibule groove, and the orthodontic buckle is arranged on the installation section. The lifting section is vertically connected to the attachment. On the one hand, the lifting section can lift the installation section to the maxillary vestibule groove, so that the installation section can better extend along the gums, reduce the contact and interaction between the installation section and the maxillary braces, and improve the traction effect of the orthodontic buckle on the maxillary braces; on the other hand, the lifting section can transmit the reaction force of the maxillary braces on the orthodontic buckle to the teeth bonded to the attachment through the attachment, and the lifting section vertically connected to the attachment can better apply a vertical or nearly vertical downward force to the teeth, which is beneficial to lower the patient's front teeth while adjusting the installation position of the attachment to apply an elongation force to the second premolar, the first molar or the second molar, so as to achieve overall regulation of the patient's teeth.

[0013] Furthermore, it also includes a first connecting member fixed to the end of the installation section, and the first connecting member is detachably connected to the top of the lifting section.

[0014] In the present technical solution, the installation section and the lifting section are detachably connected by the first connecting member, which is conducive to replacing the teeth fixed by the lifting section according to the progress of orthodontics, and more flexibly adjusting the force on the second premolar, the first molar or the second molar. For example, when wearing it for the first time, select an installation section of appropriate length, install the first connecting member at the end of the installation section, and then detachably connect the first connecting member to the top of the lifting section, such as threaded connection, so as to achieve the fixation of the installation section and the lifting section, and then fix the lifting section to the attachment on the first molar. In the process of the maxillary braces pressing down the front teeth, the first molar is subjected to a vertical downward force; as the progress of orthodontics changes, when it is necessary to apply a vertical downward force to the adjacent second premolar or second molar, select an installation section of appropriate length, install the first connecting member at its end, and then fix it to the lifting section, and then fix the lifting section to the attachment of the corresponding tooth.

[0015] In this way, the tooth position on which the attachment acts can be flexibly adjusted according to the course of orthodontic treatment to better suit the treatment progress of orthodontic patients. Moreover, it also avoids the same tooth being subjected to elongation forces all the time during the orthodontic process, which is not conducive to the overall regulation of the tooth.

[0016] As another preferred structure of the longitudinal force applying device in the present invention, the mounting arch wire includes a mounting section for mounting the orthodontic buckle, the end of the mounting section is connected to an adjusting sleeve, a second cavity is provided on the adjusting sleeve, an adjusting rod is provided in the second cavity, one end of the adjusting rod is threadedly connected to the second cavity, and the other end of the adjusting rod is rotatably connected to a second connecting piece, and the second connecting piece is connected to a lifting section vertically connected to the accessory.

[0017] In the technical solution, the arch wire installation not only includes a mounting section and a lifting section, but also an adjustment sleeve, an adjustment rod and a second connecting member located between the mounting section and the lifting section. One end of the adjustment sleeve is connected to the end of the mounting section, and the angle between the mounting section and the adjustment sleeve can be adjusted by flipping the mounting section relative to the adjustment sleeve. The other end of the adjustment sleeve is connected to the adjustment rod, and the adjustment rod is preferably coaxially arranged with the adjustment sleeve. The end of the adjustment rod is rotatably connected to the second connecting member, so that the adjustment rod can rotate relative to the second connecting member, but does not generate movement along the axial direction of the adjustment rod.

[0018] When in use, the angle between the mounting section and the adjustment sleeve can be adjusted by flipping the mounting section. In some embodiments, the adjustment sleeve and the mounting section can be an integral structure, for example, the end of the mounting arch wire is defined as the adjustment sleeve, and a second cavity for connecting the adjustment rod is provided on the adjustment sleeve, and the angle between the mounting section and the adjustment sleeve is adjusted by bending the mounting arch wire; in some embodiments, the adjustment sleeve and the mounting section are two independent components, and the two are connected by a hinge to allow the mounting section to flip a certain angle relative to the adjustment sleeve. At the same time, by screwing a part of the adjustment rod into or out of the second cavity, the total length of the adjustment sleeve and the adjustment rod can be fine-tuned, and the total length of the mounting arch wire can be extended or shortened.

[0019] Through the above-mentioned settings, the angle between the installation section and the adjustment sleeve, as well as the total length of the installed arch wire can be flexibly changed according to the orthodontic progress and needs, thereby adjusting the position of the orthodontic buckle relative to the maxillary braces, which is beneficial to adjust the magnitude and direction of the traction force on the maxillary braces and improve the effect of lowering the anterior teeth; in addition, the adjustment of the angle and total length is also beneficial to changing the force of the lifting section on the accessories, and further fine-tuning can be made after replacing the teeth where the lifting section is located, so that the adjustment operation is more flexible and simple.

[0020] Furthermore, the end of the mounting section is hingedly connected to the adjusting sleeve.

[0021] In the present technical solution, the mounting section and the adjusting sleeve are two independent components. In one or more embodiments, a bearing can be provided on the adjusting sleeve, and a pin can be provided at the end of the mounting section, and a hinge connection between the adjusting sleeve and the mounting section can be achieved through the cooperation between the pin and the bearing. In some embodiments, a torsion spring is also provided in the bearing to provide a certain angle support for the mounting section. In some embodiments, a pin hole can be provided on the mounting section, and a pin can be provided on the adjusting sleeve, and a hinge connection between the two components can be achieved through the cooperation between the pin hole and the pin. By arranging the mounting section and the adjusting sleeve as a hinge connection, the angle between the two components can be adjusted more conveniently, and the angle adjustment at both ends of the mounting section can be more consistent, thereby avoiding the situation where the bending angles at both ends of the mounting section are difficult to adjust to be consistent when the mounting section and the adjusting sleeve are an integrated structure.

[0022] Furthermore, a supporting mechanism connected to the teeth of the upper jaw through an accessory is provided between the end of the arch wire installation and the orthodontic buckle, and the supporting mechanism includes a shell, a slide groove and a knob are provided on the shell, a rotating rod is provided on the knob, a second rack is provided on the rotating rod, the rotating rod movably passes through the shell and extends to a third cavity located in the shell, a moving rod is provided in the third cavity, a first rack meshing with the second rack is provided on the moving rod, and a connecting shaft, the connecting shaft extends to the outside of the slide groove and is connected to a support for supporting the arch wire installation.

[0023] In this technical solution, the rotating knob drives the rotating rod connected to the knob to rotate, thereby driving the second rack to rotate. The rotating second rack drives the meshing first rack to move, prompting the moving rod to move vertically in the third cavity, thereby driving the connecting shaft and the support member to move up and down along the slide groove provided on the housing.

[0024] In the present technical solution, a supporting mechanism is provided to support the arch wire of the mounting section, thereby increasing the rigidity of the mounting arch wire and preventing the orthodontic buckle from moving downward after long-term wearing, thereby ensuring that the longitudinal force applying device applies sufficient longitudinal force to the maxillary braces; at the same time, the provision of the supporting mechanism can also make the angle adjustment of the mounting section more convenient, and can quickly adjust the mounting section to the desired angle; not only that, by fixing the supporting mechanism to the teeth, such as the first premolars, through accessories, it is also possible to apply a downward extension force to the teeth, thereby achieving adjustment of teeth other than the front teeth.

[0025] Furthermore, a guide rod is connected between the top and bottom surfaces of the third cavity, and the moving rod is movably arranged on the guide rod. The guide rod is conducive to improving the rigidity of the moving rod, thereby enhancing the stability of the support mechanism for installing the arch wire.

[0026] Furthermore, the accessory for fixing and installing the arch wire is connected to the first molar, the second molar or the second premolar of the maxilla, and the accessory for fixing the supporting mechanism is connected to the first premolar of the maxilla. During the wearing process, when the orthodontic buckle acts as a fulcrum to provide a longitudinal force to the maxillary braces, the accessory also provides a downward force on the tooth where it is located, thereby achieving the elongation of the molar while achieving the depression of the anterior teeth. In the present technical solution, the accessory for fixing and installing the arch wire can be installed on the first molar, the second molar or the second premolar as the progress of orthodontics varies, which can also avoid the same tooth being continuously subjected to the force of the accessory during long-term wearing. Since the supporting mechanism is used to assist in supporting the installation of the arch wire, the supporting mechanism can be installed or not. When installing the supporting mechanism, it is preferably fixed on the first premolar, which can simultaneously elongate the first premolar.

[0027] Another object of the present invention is to provide a set of braces assembly, which includes a maxillary braces and any one of the aforementioned longitudinal force applying devices, wherein a third connecting piece is provided on the maxillary braces, and the third connecting piece is connected to the orthodontic buckle of the longitudinal force applying device through a rubber band.

[0028] In the technical solution, the third connecting piece of the maxillary braces is used to connect the rubber band, which can also adopt the structure of an orthodontic buckle. In some preferred embodiments, the third connecting piece and the orthodontic buckle of the longitudinal force applying device are both located near the upper front teeth to provide a vertical upward longitudinal force to the maxillary braces.

[0029] Furthermore, it also includes a mandibular brace, the maxillary brace is provided with an extension portion, the extension portion is provided with an inclined guide plate, and the inclined guide plate is used to guide the mandibular brace to move forward.

[0030] In the technical solution, an extension is also provided on the maxillary brace, and a bevel guide plate is formed on the extension. An occlusal groove for positioning is formed between the bevel guide plate and the front teeth area of ​​the maxillary brace, and the surface structure of the occlusal groove matches the front teeth area of ​​the mandibular brace. When biting, the lower front teeth bite into the occlusal groove in front of the bevel guide plate, leading the lower jaw forward, so that the lower jaw moves forward, which is beneficial for orthodontic patients to improve mandibular retraction.

[0031] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0032] 1. The present invention can continuously apply longitudinal force to the maxillary braces during wearing of the maxillary braces by fixing the mounting arch wire on the teeth and using the orthodontic buckle on the mounting arch wire as a fulcrum for traction, thereby effectively improving the effect of lowering the anterior teeth; and the entire device has a simple, compact and non-invasive structure, can be well arranged in the maxillary vestibule groove of the orthodontic patient, is not easily disturbed by external forces, and does not significantly affect the appearance and image of the orthodontic patient, which is conducive to the promotion and application of the device;

[0033] 2.

The present invention can flexibly adjust the teeth on which the attachments act according to the progress of orthodontics, better fit the correction progress of orthodontic patients, and also avoid the same tooth being subjected to a vertical downward force for too long during the orthodontic process, that is, an elongation force, which is not conducive to the overall regulation of the tooth;

[0035] 4. The present invention can flexibly change the angle between the installation section and the adjustment sleeve, as well as the total length of the installed archwire according to the orthodontic progress and needs, and then adjust the position of the orthodontic buckle relative to the maxillary braces, which is beneficial to adjust the magnitude and direction of the traction force on the maxillary braces and improve the effect of lowering the anterior teeth; in addition, the adjustment of the angle and the total length is also beneficial to change the force of the lifting section on the attachment, and further fine-tuning can be made after replacing the teeth where the lifting section is located, so the adjustment operation is more flexible and simple;

[0036] 5. The present invention can support the archwire of the installation section by providing a support mechanism, thereby improving the rigidity of the installation archwire, avoiding the situation where the orthodontic buckle moves downward after long-term wearing, and ensuring that the longitudinal force applying device applies sufficient longitudinal force to the maxillary braces; at the same time, the provision of the support mechanism can also make the angle adjustment of the installation section more convenient, and can quickly adjust the installation section to a desired angle; not only that, by fixing the support mechanism on the teeth, such as the first premolars, through accessories, it is also possible to apply a downward force to the teeth, thereby achieving adjustment of other teeth other than the front teeth;

An occlusal groove for positioning is formed between the bevel guide plate and the front teeth area of ​​the maxillary brace, and the surface structure of the occlusal groove matches the front teeth area of ​​the mandibular brace. When biting, the lower front teeth bite into the occlusal groove in front of the bevel guide plate, leading the lower jaw forward, so that the lower jaw moves forward, which is beneficial for orthodontic patients to improve the mandibular retrusion.

[0078] In some embodiments, a second magnet 55 is further disposed in the inclined guide plate 53, and a third magnet 61 is disposed in the front tooth region of the mandibular braces. The second magnet 55 is placed transversely, so that the polarity of the inclined guide plate close to the occlusal groove and the side away from the occlusal groove are different, for example, Fig. 9 As shown, the side of the second magnet close to the bite groove is the S pole, and the side away from the bite groove is the N pole; the third magnet 61 is placed vertically, and the polarity of its vertically upward end is different from the polarity of the side of the second magnet close to the bite groove, and is the same as the polarity of the side of the second magnet away from the bite groove, as shown in FIG. Fig. 9 As shown, the upper end of the third magnet is a N pole.

[0079] With this structure, when the anterior tooth area of ​​the mandibular braces of orthodontic patients is close to the occlusal groove, Fig. 9 As shown, the mandibular braces are guided into the occlusal groove by magnetic attraction, and the mandibular braces are located away from the occlusal groove, as shown in FIG. Fig.10 When the other side of the inclined guide plate is shown, the repulsive effect of the magnets can be used to remind the orthodontic patient that the current mandibular braces are in an incorrect occlusal position, prompting the orthodontic patient to adjust the mandibular position so as to insert the mandibular braces into the correct occlusal position in the occlusal groove.
