Description

Technical Field

[0001] The utility model relates to the technical field of oral orthodontics, and particularly relates to a mandibular deviation corrector. Background Art

[0002] Mandibular deviation refers to the deviation between the mandible and the maxilla, resulting in improper tooth occlusion and even affecting the facial contour. Mandibular deviation may be caused by congenital developmental abnormalities, or may be related to long-term chewing habits or living habits, such as supporting the face with hands, which can all lead to mandibular deviation.

[0003] Generally, the treatment methods for mandibular deviation vary according to the severity. For mild or moderate deviation, manual reduction can be used for correction, while for severe deviation, surgical treatment is required.

[0004] However, for mild to moderate deviation, manual reduction not only requires treatment in a specialized hospital, but also has a high treatment cost. At present, there is no corresponding corrector for correcting mild to moderate deviation.

[0005] Therefore, there is an urgent need to provide a mandibular deviation corrector to solve the problems existing in the prior art to a certain extent. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a mandibular deviation corrector to correct the mandibular deviation of patients with mild to moderate mandibular deviation.

[0007] A mandibular deviation corrector provided by the utility model includes a base component and an extension member; the extension member and the base component are of a split structure, and the extension member can be connected to any side of the base component; the base component is used to fit with the maxilla, and one end of the extension member away from the base component extends between the mandibular posterior teeth and the lingual side.

[0008] Wherein, a first fitting portion is formed on one side of the extension member facing the base component, a second fitting portion is formed on one side of the base component facing the extension member, and the first fitting portion and the second fitting portion are inserted into each other to detachably connect the extension member and the base component.

[0009] Specifically, there are multiple first fitting portions, and the multiple first fitting portions are arranged at intervals. There are multiple second fitting portions, the multiple second fitting portions are arranged at intervals, and the arrangement intervals of the multiple second fitting portions are the same as those of the first fitting portions.

[0010] Furthermore, the number of the second fitting portions is greater than the number of the first fitting portions.

[0011] Wherein, the base assembly includes a first base and a second base, the first base and the second base are connected, the second matching portion is a positioning groove, and the positioning groove is formed on the first base and the second base.

[0012] Specifically, the base assembly further includes an adjusting member, which is embedded in the first base and the second base, and one end of the adjusting member is connected to the first base, and the other end is connected to the second base.

[0013] Furthermore, threaded portions are formed at both ends of the adjusting member, so that the adjusting member is threadedly connected to the first base and the second base.

[0014] Wherein, the first substrate and the second substrate both include an abutment portion and an occlusal portion, the shape of the abutment portion is adapted to the shape of the upper jaw and fits the upper jaw; the occlusal portion is located between the upper teeth and the lower teeth and is in contact with the extension member.

[0015] Specifically, the extension member includes a connecting portion and an extending portion, the connecting portion is in contact with the occlusal portion, the first matching portion is formed on the side of the connecting portion facing the occlusal portion, and the second matching portion is formed on the side of the occlusal portion facing the connecting portion; the extending portion is integrally formed with the connecting portion, and the extending portion can cover the lower gum position.

[0016] Furthermore, the base component and the extension member are both made of self-curing base resin.

[0017] Compared with the prior art, the mandibular deviation corrector provided by the utility model has the following advantages:

[0018] The mandibular deviation corrector provided by the utility model comprises a base component and an extension member; the extension member and the base component are split structures, and the extension member can be connected to any side of the base component; the base component is used to fit with the maxilla, and one end of the extension member away from the base component extends to between the mandibular posterior teeth and the lingual side.

[0019] From this analysis, it can be seen that by making the extension member and the base component in the present application a split structure, and the extension member can be connected to any side of the base component, so that it can be set on one side according to the specific needs of the user, to achieve the correction of the left deviation of the mandible or the right deviation of the mandible. It can be understood that because the extension member in the present application extends from one end of the base component away from the mandible to between the posterior teeth and the lingual side of the mandible, when the patient's mandible is deviated to the left, the patient's mandible needs to be corrected to the right, so that the extension member needs to be connected to the right side of the base component, and then the left-deviated mandible can be limited and corrected by the extension member.

[0020] Correspondingly, when the patient has a right mandibular deviation, the patient's mandible needs to be corrected to the left. Thus, by connecting the extension member to the left side of the base body, the right-deviated mandible can be limited and corrected to the left through the extension member.

[0021] Since the base body assembly in this application is used to fit with the upper jaw, during use, first connect the extension member to the base body assembly, then place the overall orthodontic appliance into the oral cavity and make the base body assembly fit with the upper jaw, and the limitation and correction of the mandible can be achieved through the extension member. Correspondingly, the mandibular deviation corrector provided in this application needs to be worn continuously. However, since the orthodontic appliance can be put into the oral cavity when in use and taken out of the oral cavity when not in use, the patient can perform orthodontic treatment at any time and place, greatly reducing the cost of correction and improving the flexibility of the correction process.

[0037] As Figures 1-4 shown, the present utility model provides a mandibular deviation corrector, including a base assembly and an extension member 4; the extension member 4 is a split structure with the base assembly, and the extension member 4 can be connected to any side of the base assembly; the base assembly is used to fit with the upper jaw, and one end of the extension member 4 away from the base assembly extends between the mandibular posterior teeth and the lingual side.

[0038] Compared with the prior art, the mandibular deviation corrector provided by the present utility model has the following advantages:

[0039] The mandibular deviation corrector provided by the present utility model has a split structure between the extension member 4 and the base assembly in this application, and the extension member 4 can be connected to either side of the base assembly, so that it can be set on the corresponding side according to the specific needs of the user, realizing the correction of left mandibular deviation or right mandibular deviation. It can be understood that since one end of the extension member 4 in this application extends between the posterior mandibular teeth and the lingual side, when the patient has a left mandibular deviation, the patient's mandible needs to be corrected to the right. Therefore, the extension member 4 needs to be connected to the right side of the base assembly, and then the left-deviated mandible can be limited and corrected through the extension member 4.

[0040] Correspondingly, when the patient has a right mandibular deviation, the patient's mandible needs to be corrected to the left. By connecting the extension member 4 to the left side of the base, the right-deviated mandible can be limited and corrected to the left through the extension member 4.

[0041] Since the base assembly in this application is used to fit with the maxilla, during use, first connect the extension member 4 to the base assembly, then put the overall corrector into the oral cavity, and make the base assembly fit with the maxilla, so that the extension member 4 can be used to limit and correct the mandible. Correspondingly, the mandibular deviation corrector provided by this application needs to be worn continuously. However, since the corrector can be put into the oral cavity when in use and taken out of the oral cavity when not in use, the patient can perform orthodontic treatment at any time and place, greatly reducing the cost of correction and improving the flexibility of the correction process.

[0042] It should be supplemented here that the mandibular deviation corrector provided by this application is preferably worn for a cumulative 14 hours per day, which can correct the mandibular deviation of mild to moderate patients.

[0043] It should be further supplemented here that in this application Figure 1 The figure shows a schematic diagram of the state of the patient's left mandibular deviation, and the direction in the figure is the direction facing the patient's oral cavity. That is, the left side of the figure is actually the right side of the patient's oral cavity, and correspondingly, the right side of the figure is the left side of the patient's oral cavity.

[0044] In this way, the split extension member 4 and the base assembly can be connected by bonding. That is, since different patients have different mandibular deviation amounts and deviation directions, the split extension member 4 and the base assembly can be connected correspondingly according to the conditions of different patients. And since the severity of deviation of different patients is also different, by connecting in the bonding way, after the patient completes the correction in the initial position, the extension member 4 can be separated from the base assembly, and the position of the extension member 4 can be further adjusted to realize further correction treatment.

[0045] Among them, as Figure 2As shown, a first mating portion is formed on one side of the extension member in the present application facing the base assembly, and a second mating portion is formed on one side of the base assembly facing the extension member. The first mating portion and the second mating portion are plugged into each other to detachably connect the extension member and the base assembly.

[0046] The first mating portion 4011 in the present application is a positioning protrusion. Correspondingly, the second mating portion 1021 is a positioning groove. The detachable connection between the extension member 4 and the base assembly is realized by plugging the positioning protrusion into the positioning groove.

[0047] Preferably, as Figure 2 shown, there are multiple first mating portions 4011 in the present application, and the multiple first mating portions 4011 are arranged at intervals. There are multiple second mating portions 1021, and the multiple second mating portions 1021 are arranged at intervals, and the arrangement intervals of the multiple second mating portions 1021 are the same as those of the first mating portions 4011.

[0048] Since the extension member 4 is required to limit the lower jaw to achieve the purpose of correction, therefore, in the present application, by providing multiple first mating portions 4011, correspondingly, multiple second mating portions 1021 with the same arrangement intervals as those of the first mating portions 4011 are formed, so that the extension member 4 can be more stably connected to the base assembly, ensuring the correction effect of the extension member 4 on the patient's lower jaw.

[0049] Further preferably, as Figure 2 shown, the number of the second mating portions in the present application is greater than the number of the first mating portions.

[0050] Since the lower jaw offset of some patients is too large, a single correction will cause the patients to be more painful and produce a resistant emotion to wearing. Therefore, in the present application, by providing multiple first mating portions 4011 and making the number of the second mating portions 1021 greater than the number of the first mating portions 4011, the extension member 4 can move relative to the base assembly, so that Figure 2 taking the number shown in

[0051] It should be noted here that the diameter of the first mating part 4011 in this application is slightly larger than that of the second mating part 1021, so as to achieve a tight fit between the extension member 4 and the base assembly. The interval between the two first mating parts 4011 in this application is 2 mm, so as to cooperate with the second mating part 1021 to have an adjustment ability of up to 4 mm.

[0052] It should be further noted here that the illustration in this application is only one of the implementation manners, and the numbers of the first mating part 4011 and the second mating part 1021 can also be increased or decreased according to requirements, so as to increase the connection stability between the two and the diversity of the adjustment positions. For example, there can be three first mating parts 4011 and five second mating parts 1021, or two first mating parts 4011 and five second mating parts 1021.

[0053] Optionally, as Figure 3 shown, the base assembly in this application includes a first base 1 and a second base 2. The first base 1 and the second base 2 are connected. The second mating part 1021 is a positioning groove, and positioning grooves are formed on both the first base 1 and the second base 2.

[0054] By forming positioning grooves on both the first base 1 and the second base 2, the purpose of connecting the extension member 4 to the first base 1 or the second base 2 according to specific correction requirements can be achieved.

[0055] Preferably, the materials of the first base 1, the second base 2 and the extension member 4 in this application are all self-curing base resins, and the first base 1, the second base 2 and the extension member 4 are all injection-molded and manufactured according to the patient's oral cavity shape during the manufacturing stage, so as to be fully adapted to the patient's oral cavity.

[0056] Optionally, as Figure 3 shown, the base assembly in this application further includes an adjusting member 3. The adjusting member 3 is buried in the first base 1 and the second base 2, and one end of the adjusting member 3 is connected to the first base 1, and the other end is connected to the second base 2.

[0057] Since most patients with mandibular deviation also need to be accompanied by maxillary arch expansion treatment during the correction process, therefore, the first base 1 and the second base 2 in this application are of a split structure, and the first base 1 and the second base 2 are connected through the adjusting member 3. Moreover, the adjusting member 3 can also adjust the first base 1 and the second base 2 to move closer to or away from each other, so as to adjust the interval between the first base 1 and the second base 2 and achieve maxillary arch expansion correction for the patient.

[0058] Preferably, threaded portions are formed at both ends of the adjusting member 3 in the present application, so that the adjusting member 3 is threadedly connected to the first base 1 and the second base 2. By rotating the adjusting member 3, the relative movement of the first base 1 and the second base 2 can be realized through threaded cooperation, thereby realizing arch expansion treatment.

[0059] Optionally, as Figure 2 shown, both the first base 1 and the second base 2 in the present application include an abutting portion 101 and a biting portion 102. The shape of the abutting portion 101 is adapted to the shape of the upper jaw and fits with the upper jaw; the biting portion 102 is located between the upper teeth and the lower teeth and is connected to the extension member 4.

[0060] Since the extension member 4 in the present application is connected to the biting portion 102, therefore, the abutting portion 101 and the biting portion 102 included in the first base 1 and the second base 2 can be positioned in the oral cavity to ensure the position accuracy of the extension member 4, thereby realizing the correction of the patient's mandibular deviation.

[0061] Optionally, as Figure 2 combined with Figure 4 shown, the extension member 4 in the present application includes a connecting portion 401 and an extension portion 402. The connecting portion 401 fits with the biting portion 102, and a first fitting portion 4011 is formed on the side of the connecting portion 401 facing the biting portion 102. The extension portion 402 is integrally formed with the connecting portion 401, and the extension portion 402 can cover the position of the lower dental arch.

[0062] The connecting portion 401 in the present application can fit with the biting portion 102 and is jointly located between the upper teeth and the lower teeth. Correspondingly, the extension portion 402 is connected to one end of the connecting portion 401, so that the extension portion 402 can cover the position of the lower dental arch to realize the correction of the patient's mandible.

[0063] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
