Description

Technical Field

[0001] This invention relates to the field of fixed orthodontic treatment, specifically to an adjustable multifunctional buccal tube. Background Technology

[0002] Orthodontics is the correction of malocclusion. The orthodontic process involves the doctor and patient working together to align misaligned teeth using brackets. Orthodontics primarily studies the etiology, diagnosis, prevention, and treatment of malocclusion. Orthodontic treatment mainly uses various orthodontic appliances to adjust the coordination between facial bones, teeth, and the nerves and muscles of the maxillofacial region. This involves correcting abnormal relationships between the upper and lower jawbones, between the upper and lower teeth, between the teeth and jawbone, and between the nerves and muscles connecting them. The ultimate goal is to achieve balance, stability, and aesthetics in the stomatognathic system. The correction of malocclusion mainly relies on wearing orthodontic appliances inside or outside the mouth to apply appropriate "bioforce" to the teeth, alveolar bone, and jawbone, causing physiological movement and thus correcting the malocclusion.

[0003] To achieve the best orthodontic results, buccal tubes are often bonded to the molars. These tubes allow the orthodontic archwire to be inserted and fixed in place. The buccal tubes are also designed with small hooks that can be used to attach rubber bands for intramaxillary or intermaxillary traction.

[0004] Some targeted buccal tubes have also appeared in the prior art, such as the buccal tube shown in application number: 201610477615.2, application publication number CN 105997276 A. The buccal tube is two-sectioned. The inventor mainly considered that this design can pull out the archwire at the middle opening. This solution reduces the length of the archwire in the buccal tube. It may cause the archwire and the appliance to lose control of the teeth, which is not explained. The buccal tube shown in application number 202021496503.X and authorization number CN 213588543 U is a double tube type. The inventors considered using double wires to close the gap and prepare the teeth for anchorage, generating a double force to control the anchorage teeth. Although this solution can accomplish the above-mentioned content, the orthodontic appliance is too large and the orthodontic treatment is too complicated, making it difficult to use in clinical practice.

[0005] Publication number CN 1883416A provides a good buccal tube design, which can indeed provide good anchorage control for crowded cases, but it has no advantage for cases with well-aligned teeth and protrusion.

[0006] It is evident that the buccal tubes disclosed in the existing technology, such as transmission orthodontic appliances and physiological anchorage appliances, have a narrow scope of application and are difficult to treat most cases with a single appliance. Therefore, it is necessary to design a buccal tube that is applicable to both types of major cases. Summary of the Invention

[0007] The present invention aims to overcome the shortcomings of the prior art by providing an adjustable multifunctional cheek tube.

[0008] This application provides the following technical solution: An adjustable multifunctional cheek tube includes a substrate, a main body block on the substrate, and a traction hook on the main body block. The main body block has a first through hole along its axial direction. A first protrusion extends from the upper surface of the main body block on one side of the traction hook, and an oblique hole communicating with the first through hole is provided on the first protrusion. A second protrusion extends from the lower surface of the main body block, and a second through hole is provided on the second protrusion. The second through hole communicates with the first through hole, and its axis is perpendicular to the axis of the first through hole.

[0009] Based on the above technical solutions, the following further technical solutions are also possible: The oblique hole is a circular hole with an inclination angle of 45°.

[0010] The second through hole is a pentagonal hole composed of a square and a triangle.

[0011] The first protrusion is located at one end of the main body block.

[0012] The second protrusion is located at the other end of the main body block.

[0013] The substrate has an arc surface on one side.

[0014] The back of the main block extends outwards with a ramp that connects to the substrate, and the ramp has an inclination angle of 10 degrees.

[0015] One end of the main block extends a certain distance beyond the substrate area.

[0016] An indicator ring groove is provided at one end of the main body block.

[0017] Advantages of the invention: This invention has a simple structure and is easy to use. It is more effective in controlling the tilt and rotation of teeth, especially when teeth move mesially, as tooth rotation is more likely to occur. It can effectively control undesirable tooth rotation when a large range of tooth movement is required. Since the first and second through holes and the oblique holes can be used in combination, different combinations can control the crown-distal and root-mesially tilt of the tooth. This is more beneficial when it is necessary to strengthen the anchorage of molars. It can control the crown-mesially and root-distal tilt of the tooth and weaken the anchorage of molars. Depending on the clinical situation of the use of this device, one end of the main block can be ground off in a timely manner. The length of the body after grinding is the standard length, and the removal does not affect the adjustment of other teeth. Attached Figure Description

Detailed Implementation

[0019] like Figure 1-6 As shown, an adjustable multifunctional cheek tube includes a substrate 1, which is rectangular with a flat upper surface and an arc surface 1a lower surface.

[0020] A ramp 1b is connected to the upper surface of the substrate 1, with an inclination angle of 10 degrees. A rectangular columnar main body block 2 is connected to the ramp 1b, with one end of the main body block 2 extending outward from the substrate 1 as an extension portion 9. A first through hole 4 is provided on the main body block 2, which is square and penetrates the left and right end faces of the main body block 2.

[0021] A second protrusion 2b extends outward from the lower surface of the extension portion 9. A second through hole 6 is provided on the second protrusion 2b, penetrating upward through the upper surface of the main body block 2. The second through hole 6 is a pentagonal hole composed of a square and a triangle, with one corner pointing towards the other end of the main body block 2. The second through hole 6 communicates with the first through hole 4, and its axis is perpendicular to the axis of the first through hole 4.

[0022] An indicator groove 8 is distributed on one end of the main body block 2 on one side of the second through hole 6, and the axis of the indicator groove 8 is parallel to the axis of the first through hole 4.

[0023] A traction hook 3 is connected to the upper surface of the main body block 2. A first protrusion 2a extends from the upper surface of the main body block 2 on one side of the traction hook 3, and one side wall of the first protrusion 2a is coplanar with the end face of the other end of the main body block 2. The substrate 1, the ramp 1b, the main body block 2, the extension 9, the first protrusion 2a and the second protrusion 2b of the present invention are an integral structure.

[0024] The first protrusion 2a has an oblique hole 5, which is a circular hole with an inclination angle of 45°, communicating with the first through hole 4. The presence of the first protrusion 2a and the second protrusion 2b significantly increases the distance between the oblique hole 5 on the upper surface of the first protrusion 2a and the second through hole 6 on the lower surface of the second protrusion 2b. This provides anchorage preparation for the teeth bonded by the device, causing the tooth root to move mesially and the crown distally. The raised step increases the length of the archwire inside the appliance, making tooth control more effective.

[0025] like Figure 7 As shown in (a), one end of the nickel-titanium wire 7 is inserted into the oblique hole 5 on the upper surface of the first protrusion 2a, and then extends out from one end of the second through hole 6 on the lower surface of the second protrusion 2b. The entire nickel-titanium wire 7 is distributed in a downward oblique direction, with the wire entering from the top and exiting from the bottom.

[0026] As shown in (b), the nickel-titanium wire 7 passes through the first through hole 4 in a straight line.

[0027] As shown in (c), one end of the nickel-titanium wire 7 is inserted through the first through hole 4, and then extends out from the other end of the second through hole 6 on the upper surface of the main body block 2. The entire nickel-titanium wire 7 presents an upwardly inclined distribution that is approximately downwardly inserted and obliquely upwardly exited.

[0028] The extension 9 extending from one end of the main body block 2 of this device onto the base plate is more effective for controlling the tilt and rotation of teeth, especially when teeth move mesially, as rotation is more likely to occur. It effectively controls undesirable tooth rotation for teeth requiring a large range of movement. Furthermore, the extension 9 can be ground down as needed clinically, and the length of the main body block 2 after grinding is the standard length, without affecting the adjustment of other teeth. When grinding down the extension 9, the indicator groove 8 is used as the baseline for grinding; that is, part of the second through hole 6 will be removed after grinding.
