Description

Technical Field

[0001] The utility model mainly relates to the technical field of medical devices for fixed orthodontics in the oral cavity, and specifically relates to a new type of orthodontic square wire for the oral cavity. Background Technique

[0002] Orthodontic tooth movement stems from the application of orthodontic forces, which are generated by various appliances. In medical devices for fixed orthodontics in the oral cavity, orthodontic brackets and orthodontic wires are important components of fixed orthodontic techniques. The brackets are bonded to the surface or lingual side of the tooth crown, and doctors can apply the orthodontic forces generated by orthodontic arch wires, elastic rubber bands, orthodontic springs, etc. to the teeth with the help of the brackets.

[0003] The groove width of orthodontic brackets is often designed to be 0.018 inches (0.46 mm) and 0.022 inches (0.56 mm), and the groove depth is generally 0.025 inches (0.64 mm) and 0.028 inches (0.71 mm), that is, there are mainly two sizes of brackets: 0.018×0.025 inches and 0.022×0.028 inches. When selecting brackets clinically, the clearance between the arch wire and the bracket groove is often considered. Smaller-sized square wires cannot effectively express the torque preset in the bracket groove. On the other hand, the smaller the torque data preset in the bracket groove, the larger-sized square wire is required to achieve torque control of the teeth. Nowadays, with the popularization of CAD / CAM (Computer Aided Design and Manufacturing Technology), personalized bracket systems are processed and manufactured according to the different tooth shapes and treatment needs of patients, and personalized torque data is preset in the bracket grooves, aiming to achieve more precise control of teeth. Bracket manufacturers usually provide 5 - 5 brackets, that is, a total of 20 brackets. If each bracket is processed individually, the processing cost is high and it is not suitable for mass production.

[0004] The width dimensions of orthodontic square wires on the market are mostly 0.022 and 0.025 inches, and the height dimensions of orthodontic square wires are mostly 0.014, 0.016, 0.017, 0.018, 0.019, and 0.021 inches. The clearance angle of the square wire in the bracket groove is large and cannot fully express the torque data; in addition, in the treatment of fixed orthodontics in the oral cavity, it has a serious impact on the aesthetic appearance of the human face. Many people refuse orthodontic treatment due to its unsightliness, resulting in more serious tooth ectopia. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a new type of orthodontic square wire for the oral cavity to solve the technical problems raised in the above background technique.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0011] Preferably, the internal-external combined rocker rectangular wire has the same composition as the internal-external combined rectangular wire, and the structural feature of the internal-external combined rocker rectangular wire arranged on the lingual side part is a three-dimensional arch.

[0012] Preferably, the arch rectangular wire and the rocker rectangular wire are only adapted to brackets with a width of 0.022×depth of 0.028 inches.

[0013] Preferably, the 0.026-inch rectangular wire is suitable for use in the orthodontic treatment stage of pulling the canine teeth distally or closing the extraction space by the sliding method. The height dimensions of the orthodontic rectangular wire include a total of 10 kinds: 0.010, 0.011, 0.012, 0.013, 0.014, 0.015, 0.016, 0.017, 0.018, 0.019 inches.

[0014] Preferably, the 0.027-inch and 0.028-inch rectangular wires are suitable for use in the treatment stage that requires full expression of torque and precise adjustment of teeth. The height dimensions of the orthodontic rectangular wire include a total of 5 kinds: 0.017, 0.018, 0.019, 0.020, 0.021 inches.

[0015] Preferably, chamfers are prefabricated at the top and bottom edges of the side of the 0.028-inch rectangular wire away from the contact with the bottom of the bracket slot groove.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0031] Embodiment

[0032] As Figure 1 、 2 As shown in Figures 3, 4, 5, 6, and 9, there are arcuate rectangular wires 10 and rocker rectangular wires 20. The arcuate rectangular wire 10 includes three types: the lingual rectangular wire 11, the crown surface rectangular wire 12, and the internal and external combined rectangular wire 13; the rocker rectangular wire 20 includes the rocker square-round wire 21 and the internal and external combined rocker rectangular wire 22; the internal and external combined rectangular wire 13 is composed of three parts: the lingual surface part 131, the connecting parts 132 at both ends of the lingual surface part 131, and the crown surface part 133.

[0033] It should be noted that in this embodiment, the crown surface rectangular wire 12 and the rocker square-round wire 21 are orthodontic rectangular wires only used in the crown surface area b; the lingual rectangular wire 11 is an orthodontic rectangular wire used in the lingual area a; the internal and external combined rectangular wire 13 and the internal and external combined rocker rectangular wire 22 are relatively special. The lingual surface part 131 in the component is used in the lingual area a, the crown surface part 133 is used in the posterior molar part in the crown surface area b, and the connecting part 132 is used to pass through the interdental space c to connect the above-mentioned chain parts.

[0034] Secondly, it should be noted that compared with the crown surface rectangular wire 12 being directly exposed in the crown surface area b, the lingual surface part 131 in the internal and external combined rectangular wire 13 is hidden in the lingual area a, that is, while ensuring the same effect as the crown surface rectangular wire 12, it also adds to the facial beauty of the patient during orthodontic treatment.

[0035] As Figure 1 、 2 As shown in Figures 3, 4, 5, and 6, for the arcuate rectangular wire 10 and the rocker rectangular wire 20, the width dimensions of both include three types: 0.026, 0.027, and 0.028 inches; the arcuate rectangular wire 10 and the rocker rectangular wire 20 are only adapted to brackets with a width of 0.022 × depth of 0.028 inches; the 0.026-inch rectangular wire is suitable for use during the orthodontic treatment stage of sliding the canine distally or closing the extraction space. The height dimensions of the orthodontic rectangular wire are selected from a total of 10 types including 0.010, 0.011, 0.012, 0.013, 0.014, 0.015, 0.016, 0.017, 0.018, and 0.019 inches; the 0.027- and 0.028-inch rectangular wires are suitable for use during the treatment stage that requires full expression of torque and precise adjustment of teeth. The height dimensions of the orthodontic rectangular wire are selected from a total of 5 types including 0.017, 0.018, 0.019, 0.020, and 0.021 inches.

[0036] It should be noted that in this embodiment, the width dimension of the orthodontic rectangular wire is 0.026 inches, and the height dimension is 0.016 inches; when using the sliding method to move the canine distally or close the extraction space, in order to ensure that the orthodontic rectangular wire can slide smoothly in the bracket slot, the size of the selected orthodontic rectangular wire should be at least 0.002 inches smaller than the bracket slot; therefore, the width dimension of the orthodontic rectangular wire is selected as 0.026 inches, and the height dimension is 0.016 inches, which matches the orthodontic bracket of 0.022×0.028 inches.

[0037] The width dimension of the selected orthodontic rectangular wire is 0.028 inches, and the height dimension is 0.019 inches; in order to minimize the clearance between the orthodontic rectangular wire and the orthodontic bracket as much as possible, so that the orthodontic rectangular wire can fully express torque in the bracket slot and accurately adjust the positional relationship of the teeth, the width dimension of the selected orthodontic rectangular wire is 0.028 inches, and the height dimension is 0.019 inches, which matches the orthodontic bracket of 0.022×0.028 inches.

[0038] As Figure 1 、 5 shown in 6, 7, 8, the lingual rectangular wire 11, the internal and external combined rectangular wire 13, and the lingual part of the internal and external combined rocker rectangular wire 22 are all in a shape similar to a mushroom head. The internal and external combined rocker rectangular wire 22 has the same composition as the internal and external combined rectangular wire 13. The structural feature of the internal and external combined rocker rectangular wire 22 arranged in the lingual part is a three-dimensional arch. The top and bottom edges of the 0.028-inch rectangular wire away from the side in contact with the bottom of the bracket slot are pre-chamfered 1. The materials of the arch-shaped wire 10 and the rocker-shaped wire 20 include nickel-titanium alloy, copper-nickel-titanium alloy, β-titanium alloy, and stainless steel.

[0039] It should be noted that in this embodiment, deep overbite is one of the common malocclusions clinically, which is a malocclusion deformity caused by the vertical disharmony of the dental arch and jaw bone, and it is extremely harmful to the stomatognathic system; the key point and difficulty in the treatment of deep overbite lie in the opening of the occlusion. By opening the occlusion, the sagittal relationship of the patient is adjusted in order to achieve the purpose of coordinating the vertical relationship and the sagittal relationship; clinically, it is mainly achieved by depressing the anterior teeth, elevating the molars or using both methods in combination. The rocker-shaped wire 20 is a commonly used leveling arch wire for treating deep overbite clinically, which can depress the anterior teeth.

[0040] The special structure of the rocker-shaped wire 20 will generate a positive torque of crown-labial / root-lingual direction on the entire arch wire, which can control the labial inclination or buccal inclination of the anterior teeth and posterior teeth.

[0041] When the width dimension of the selected orthodontic rectangular wire is 0.028 inches, chamfer 1 is prefabricated on the top and bottom edges of the orthodontic rectangular wire away from the side in contact with the bottom of the bracket slot to avoid the collision between the edge of the rectangular wire arch wire and the locking cover of the self-locking bracket, resulting in the problem that the locking cover of the self-locking bracket cannot be closed.

[0042] The working principle of the present utility model is as follows:

[0043] As Figure 9 shown in the diagram of the gum, it is divided into the lingual region a, the crown surface region b, and the interdental space c;

[0044] In this utility model, the crown surface rectangular wire 12 and the rocker rectangular wire 21 are orthodontic wires used only in the crown surface region b; the lingual wire 11 is an orthodontic wire used in the lingual region a; the internal and external combined wire 13 and the internal and external combined rocker wire 22 are relatively special. The lingual surface part 131 in the component is used in the lingual region a, the crown surface part 133 is used in the posterior molar part in the crown surface region b, and the connecting part 132 is used to pass through the interdental space c to connect the above-mentioned various parts of the chain;

[0045] Secondly, it should be noted that compared with the crown surface wire 12 being directly exposed in the crown surface region b, the lingual surface part 131 in the internal and external combined wire 13 is hidden in the lingual region a, that is, while ensuring the same effect as the crown surface wire 12, it also adds to the facial beauty of the patient during orthodontic treatment;

[0046] Furthermore, deep overbite is one of the common malocclusions clinically. It is a malocclusion deformity caused by the vertical disharmony of the dental arch and jaws, which is extremely harmful to the stomatognathic system; the key point and difficulty in the treatment of deep overbite lie in the opening of the occlusion. By opening the occlusion, the sagittal relationship of the patient is adjusted in order to achieve the purpose of coordinating the vertical relationship and the sagittal relationship; clinically, it is mainly through the intrusion of the anterior teeth, the extrusion of the molars or the combined use of both methods. The rocker wire 20 is a commonly used leveling arch wire for treating deep overbite clinically, which can intrude the anterior teeth;

[0047] The special structure of the rocker wire 20 will generate a positive torque of crown-labial / root-lingual direction on the whole arch wire, which can control the labial inclination or buccal inclination of the anterior teeth and posterior teeth;

[0048] In clinical treatment, orthodontic wires of different widths are selected according to the treatment stage of the patient;

[0049] The width dimension of the selected orthodontic wire is 0.026 inches and the height dimension is 0.016 inches; when using the sliding method to retract the canine distally or close the extraction space, in order to ensure the full sliding of the orthodontic wire in the bracket slot, the size of the selected orthodontic wire should be at least 0.002 inches smaller than the bracket slot; therefore, the width dimension of the orthodontic wire is selected as 0.026 inches and the height dimension is 0.016 inches, which matches the 0.022×0.028-inch orthodontic bracket;

[0050] Select an orthodontic rectangular wire with a width dimension of 0.028 inches and a height dimension of 0.019 inches; in order to minimize the clearance between the orthodontic rectangular wire and the orthodontic bracket as much as possible, so that the orthodontic rectangular wire can fully express torque in the bracket slot and accurately adjust the positional relationship of the teeth, select an orthodontic rectangular wire with a width dimension of 0.028 inches and a height dimension of 0.019 inches, which matches an orthodontic bracket of 0.022×0.028 inches;

[0051] It should be further noted that when the width dimension of the selected orthodontic rectangular wire is 0.028 inches, chamfers 1 are prefabricated on the top and bottom edges on the side of the orthodontic rectangular wire away from the contact with the bottom of the bracket slot to avoid the edge of the square wire arch wire colliding with the locking cover of the self-locking bracket, resulting in the problem that the locking cover of the self-locking bracket cannot be closed.

[0052] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any modifications made on the basis of the technical solution according to the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
