Description

Technical Field

[0001] The utility model relates to the field of impacted canine traction, in particular to a bottom plate triangle bonding type T-shaped tube used for traction of impacted maxillary canines. Background Art

[0002] When a tooth cannot erupt into the normal occlusal position due to improper positioning in the jaw, it is called an impacted tooth and needs to be pulled out with an orthodontic traction device.

[0003] 1. For orthodontic patients who use traditional metal tongue buckles for traction clinically, sufficient crown exposure area is required, generally requiring an enamel height of 3mm; and metal tongue buckles have a strong foreign body sensation and are prone to cause mucosal ulcers.

[0004] 2. For orthodontic patients who use traditional metal tongue buckles in clinical practice, a window surgery is required to obtain sufficient crown exposure area. Therefore, the surgical field is often unclear and the isolation is not in place due to bleeding from the wound, which leads to poor bonding position or loose bonding, affecting the traction effect.

[0005] 3. For orthodontic patients who use traditional metal tongue buckles in clinical practice, excessive tooth traction may occur due to the patient's failure to return for follow-up visits in a timely manner.

[0006] 4. For the clinical use of sequential bending devices, the need for multiple activations increases the number of follow-up visits for patients.

[0007] 5. In traditional metal tongue buckle traction devices, the traction force exerted on the teeth is often located on the occlusal side and the force arm is short, and the traction efficiency is average.

[0008] Therefore, it is necessary to provide a base plate triangular bonded T-tube for traction of maxillary impacted canines to solve the above technical problems. Utility Model Content

[0009] In order to solve the above technical problems, the utility model provides a bottom plate triangular bonding T-tube for traction of impacted maxillary canines.

[0010] The utility model provides a base plate triangular bonding T-tube for traction of maxillary impacted canines, comprising a bonding portion for bonding to the impacted canines, a connecting column fixed near the center of the outer wall of the bonding portion, a blocking portion fixed at the end of the connecting column, a connecting arm fixed to the side wall of the connecting column, a horizontal tube for threading a correction arch wire fixed at the end of the connecting arm, and the horizontal tube and the connecting arm form a T-shaped structure as a whole.

[0011] Preferably, the connecting arm is arranged perpendicular to the connecting column, and the connecting arm is arc-shaped.

[0012] Preferably, the bonding portion is in the shape of a right-angled isosceles triangle as a whole, and the three corners of the bonding portion located in the right-angled isosceles triangle are all provided with rounded corners.

[0013] Preferably, the inner side of the bonding portion is provided with a contoured surface that matches the outer wall of the tooth, and the contoured surface is provided with anti-slip grooves.

[0014] Preferably, the outer edge of the blocking portion is arc-shaped.

[0015] Preferably, the length dimensions of the T-tube are 3mm, 5mm, 7mm and 9mm.

[0016] Compared with the related art, the present invention has the following beneficial effects:

[0017] 1. Once there is a minimum 2mm enamel height available to allow for adequate isolation using standard bonding solutions, it can be bonded to the teeth, with a wide range of adaptability; the triangular and curved base plate's cusp-contouring design maximizes the use of the erupted crown area; the base plate's rounded triangular design reduces foreign body sensation and increases comfort.

[0018] 2. Once the enamel height reaches 2mm, fenestration surgery can be avoided. Even if a fenestration is performed, a smaller exposure area is required, resulting in less trauma, thus avoiding poor bonding and poor bonding position caused by inadequate isolation or unclear surgical field in traditional surgical fenestration.

[0019] 3. Compared with traditional elastic traction, the connection arm is designed to be highly positioned at the FA point, thus avoiding excessive traction. This allows the NiTi wire to be placed closer to the FA point of the impacted tooth, even though this part of the tooth is still below the gum. This results in greater deformation of the NiTi wire, which in turn generates greater traction force, resulting in more efficient tooth movement and shortened treatment time.

[0020] 4. Compared with sequential bending, this device does not require multiple activations. By adjusting the height of the connector, the deformation angle of the archwire can be changed, generating greater traction force and reducing the number of patient visits.

[0021] 5. This design takes into account the impaction of the labial and lingual sides and designs T-tube devices of different heights. The overall height is 3mm, 5mm, 7mm, and 9mm. This not only increases the traction arm, but also enables the bending angle of the NITI correction archwire to reach about 50-70 degrees, thereby improving traction efficiency.

[0027] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0028] Please refer to Figures 1 to 4 A triangular, bonded T-tube with a base plate for maxillary canine distraction. Its core structure consists of a specially designed bonding section 1, designed to securely bond to the impacted canine. A connecting post 2 is fixed near the center of the outer wall of the bonding section 1, with a carefully designed stopper 3 at the end.

[0029] Furthermore, a flexible connecting arm 4 is fixed to the side wall of the connecting post 2. The design of this connecting arm 4 is crucial, as it not only forms a stable vertical structure with the connecting post, but also has an arc shape that provides good contact with the tooth surface. A horizontal tube 5 is also fixed to its end. This horizontal tube 5 is specifically used to pass the orthodontic arch wire, and together with the connecting arm 4, it forms a T-shaped structure. This design not only conforms to mechanical principles but also ensures the stability and effectiveness of the orthodontic arch wire during the traction process.

[0030] Clinical application: Figure 4 As shown, this device can be used to pull partially erupted impacted canines. The bonding portion 1 is bonded to the erupted tooth crown, the height of the horizontal tube 5 is located at the FA point (the center point of the labial crown of the tooth), and the NITI correction arch wire is passed through the horizontal tube 5. The NITI correction arch wire is bent at an angle of about 50-70 degrees, which can generate maximum traction on the impacted canine until a conventional bracket can be bonded to the crown FA point, and finally incorporated into a conventional fixed orthodontic system.

[0031] In addition, the connecting arm 4 of this T-tube is arranged perpendicularly to the connecting column 2. When the correction arch wire is installed, the tension on the connecting arm 4 will be in the center position. This design makes the connection between the connecting arm 4 and the connecting column 2 more stable, thereby ensuring the smooth progress of the traction process.

[0032] The overall design of the adhesive portion 1 is also quite ingenious. It adopts the shape of a right-angled isosceles triangle, which not only saves materials but also makes the use process more comfortable. At the same time, the three corners of the adhesive portion 1 are provided with rounded corners 6, which is both beautiful and practical.

[0033] To further enhance the bonding effect, a contoured surface 7 is designed on the inner side of the bonding portion 1 to perfectly match the outer wall of the tooth. Furthermore, anti-slip grooves 8 are meticulously provided on this contoured surface 7, making the bonding between the bonding portion and the tooth more secure and reliable.

[0034] Finally, it's worth mentioning that the outer edge of the blocking portion 3 is designed to be curved, making it more comfortable when in contact with the skin inside the mouth, effectively reducing patient discomfort. The T-tube is also available in four lengths: 3mm, 5mm, 7mm, and 9mm. This design allows the T-tube to be suitable for impacted canines of varying impaction directions, angles, and heights, meeting the needs of different patients.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
