Description

TECHNICAL FIELD

[0001] The present application relates to the field of dentistry, in particular to a zirconia ceramic buccal tube. BACKGROUND

[0002] The buccal tube is a key anchoring component fixed on the buccal side of the molar in orthodontic treatment, and its core role is to guide the orthodontic arch wire through and transmit the correction force, while assisting in controlling the tooth movement direction.

[0003] The existing buccal tube is usually made of metal material, which has certain strength, but has the problems of poor biocompatibility, insufficient aesthetics, and easy to cause tooth demineralization; at the same time, the bonding surface of the existing buccal tube has limited contact area with the teeth, resulting in insufficient bonding stability and easy to fall off under the complex stress environment in the oral cavity. SUMMARY

[0004] The purpose of the present application is to provide a zirconia ceramic buccal tube that can improve the bonding stability of the buccal tube and improve the overall structural strength of the buccal tube.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0022] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0023] like Figures 1-6 The present invention provides a zirconia ceramic buccal tube, comprising an integrally formed main body 1, an adhesive base plate 2, and a traction hook 3. The adhesive base plate 2 is disposed on the adhesive side of the main body 1, the archwire passes through the opening structure at the main body 1, and the traction hook 3 is located on the side of the main body 1 for use in conjunction with the elastic ligature during orthodontic treatment.

[0024] The integrated molding of the main body, bonding base plate, and traction hook ensures the overall structural strength stability of the buccal tube, avoiding stress concentration caused by weak connections between the main body, bonding base plate, and traction hook. The opening structure at the main body guides the archwire path, and the angle of the opening structure can be precisely guided to move the archwire in a preset direction according to the patient's own orthodontic biomechanics design, assisting in aligning teeth and adjusting occlusion. The traction hook can be used with elastic ligatures such as rubber bands and traction chains to achieve specific orthodontic goals such as closing extraction gaps and molar distalization.

[0025] Among them, the main body 1, the bonding base plate 2 and the traction hook 3 are integrally formed by zirconia ceramic additive manufacturing. Through the biocompatibility of zirconia ceramic material, patients can avoid problems such as allergies and periodontal sensitivity.

[0026] Preferably, the opening structure of the main body 1 is a horizontally through rectangular channel, and a metal sleeve 4 is installed inside the opening structure so that the metal sleeve 4 supports the main body 1, and the bow wire passes through the inside of the metal sleeve 4.

[0027] Specifically, the metal sleeve provides support and reinforcement to the opening structure, effectively preventing micro-cracks or damage to the zirconia ceramic material under long-term stress. At the same time, the friction between the inner wall of the metal sleeve and the archwire is reduced, which is beneficial for the sliding adjustment of the archwire during the correction process. The outer diameter of the metal sleeve is interference-fitted with the opening structure to ensure a stable assembly and prevent it from loosening or falling off.

[0028] Preferably, the traction hook 3 has an L-shaped structure, and the end of the traction hook 3 has a spherical end 5, the diameter of which is larger than the diameter of the traction hook 3.

[0029] Specifically, the traction hook, in conjunction with elastic ligatures such as rubber bands and traction chains, achieves functional treatment goals such as closing extraction gaps and distalizing molars. Furthermore, because the diameter of the ball end is larger than that of the traction hook rod, it effectively prevents the elastic ligature from accidentally slipping off the end of the traction hook, thus improving the safety of clinical operation and the reliability of orthodontic treatment. The smooth surface of the ball end avoids scratching the patient's oral soft tissues and improves wearing comfort.

[0030] Preferably, the surface of the adhesive base plate 2 is provided with a micropore array 6.

[0031] Specifically, the microporous array structure greatly increases the bonding area between the adhesive base plate and the adhesive, forming a strong mechanical fit, effectively improving adhesive durability, and reducing the risk of bracket detachment due to adhesive failure during orthodontic treatment.

[0032] In one embodiment of this solution, the individual micropores in the micropore array 6 are circular, triangular, or polygonal. Since different micropore shapes have different anchoring effects on the adhesive, for example, the bonding effect of a circular micropore is less than that of a triangular micropore, which is less than that of a polygonal micropore. Therefore, different shapes of micropores can be selected according to clinical needs to adjust the bonding strength. Customized micropore designs can be carried out according to the symptoms of different patients to achieve personalized fixation strength matching.

[0033] Preferably, the main body 1 has recessed areas 7 on both sides, and the recessed areas 7 and the sides of the main body 1 are in a circular arc or inclined transition.

[0034] Specifically, when removing a buccal tube, it is usually necessary to apply force by clamping the two sides of the main body with dental dismantling forceps. The concave areas on both sides of the main body of this solution can precisely fit with the jaws of the dismantling forceps, effectively preventing the forceps from slipping during dismantling and reducing the risk of damage to adjacent tooth tissues. At the same time, the arc or inclined transition between the concave areas and the sides of the main body allows the dismantling forceps to guide and correct the jaw position of the forceps if the clamping position is slightly off, thereby ensuring the stability and safety of the dismantling process and avoiding bracket breakage or tooth surface damage due to improper force application.

[0035] Preferably, the traction hook 3 is inclined to the side away from the adhesive base plate 2.

[0036] Specifically, the tilted design of the traction hook, which deviates from the bonding base plate, keeps the traction hook away from the teeth or periodontal area, further preventing irritation of the gums or impact on oral hygiene due to the traction hook being too close. It also provides more adjustment space for the archwire and optimizes the direction of orthodontic force application. At the same time, because the traction hook is deviated from the teeth or periodontal area, one end of the traction hook will inevitably protrude into the oral cavity. At this time, the ball-shaped end can reduce the friction and pressure of the traction hook end on the soft tissues inside the oral cavity, reducing the risk of oral mucosal abrasion and ulceration, thereby simultaneously ensuring the health and safety of teeth, periodontium, and oral soft tissues.

[0037] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
