Abstract

The utility model discloses a low-resistance impact-resistant banded straight wire arch cheek tube, and belongs to the technical field of orthodontic appliances. The buccal tube comprises a buccal tube body provided with an arch wire channel, wherein the inner side surface of the buccal tube body is an adhesive surface without an outer convex flange, the peripheral edge of the buccal tube body is flush with the side surface of the tube body, the attack surface is obviously reduced, and the outer side, which is close to the occlusal surface of teeth, is provided with a streamline arc surface which is in smooth transition from the top to the outer side, so that food can be guided to slide along the arc surface, and the impact force is reduced. The outer side surface and/or the lower side surface of the buccal tube body are/is flat, so that forceps or pliers can stably clamp the buccal tube body conveniently, a traction hook is further arranged on the lower side portion, and the main body of the traction hook is located in the outline projection range of the buccal tube, so that the resistance is prevented from being increased due to protruding outwards. The utility model solves the problem that the traditional buccal tube is easy to fall off due to food impact by combining the flangeless bonding surface with the streamline arc-shaped surface and the drainage ditch, and simultaneously improves the operation efficiency and the comfort of patients by integrating the plane clamping structure and the traction hook, thereby being applicable to various orthodontic correction requirements.

Description

Low-resistance impact-resistant strip-shaped straight wire arch cheek tube Technical Field The utility model relates to the technical field of dental orthodontics, in particular to a low-resistance impact-resistant banded straight wire buccal tube and tweezers or pliers for the banded straight wire buccal tube. Background In the field of orthodontic, a buccal tube is used as a core part of a fixed appliance and is mainly used for fixing an arch wire, transmitting an orthodontic force and controlling three-dimensional movement of teeth. In the prior art, a buccal tube is generally composed of a bottom plate, a tube body and a traction hook, wherein the bottom plate is fixed on the surface of teeth through an adhesive or welded on a belt ring, and an arch wire channel is arranged in the tube body so as to realize the correction function. However, conventional designs have the following limitations: (1) Insufficient impact resistance The existing buccal tube generally comprises a bottom plate and a tube body, and the bottom plate and the tube body are often provided with flanges or expansion structures to enhance bonding stability, such as a drag hook adjustable molar buccal tube disclosed in Chinese patent No. 218739188U, but such design leads to larger attack surface, is easy to be directly impacted by food in the chewing process, and is easy to cause bonding failure or falling off after long-term use. Part improvement scheme increases the bonding area through bottom plate arcwall face or recess, but does not solve the dispersion problem of external impact force, and draw the hook and independently set up in buccal tube side more, lead to drawing the hook evagination obvious, further increase the face of attack, aggravate the risk of droing. (2) The operation is not convenient enough Existing buccal tubes lack a co-design with the clamping tool. For example, the outer side or the lower side of the tube is mostly in a non-planar structure, so that the general tweezers are easy to slip during clamping, and complex auxiliary tools are needed to be relied on. (3) The traction hook is not reasonably arranged The traditional traction hook is arranged on the side surface of the buccal tube or is independently installed, so that the traditional traction hook protrudes out of the outline of the buccal tube, the attack surface is increased, the food impact risk is increased, the oral mucosa is easily scratched, and the comfort of a patient is reduced. The prior art does not solve the contradiction between the traction hook layout and the shock resistance and comfort. In addition, in the prior art, the buccal tube forceps are used for realizing stable operation by clamping the traction hooks or adapting to the outline of the buccal tube. The forceps for buccal tube disclosed in the patent CN2023219599211 can clamp the traction hook through the L-shaped inner groove (the vertical section and the horizontal section), and prevent slipping by utilizing the geometric suitability of the groove and the traction hook. As another example, the utility model CN2021228836857 discloses forceps for a high stability buccal tube, which uses a snap ring and a spring structure to clamp holes on two sides of the buccal tube, and combines a graduated scale to control the bonding height. And as disclosed in patent CN2016201956182, the special orthodontic forceps for the buccal tube are designed to be attached to the gap below the buccal tube hook through the beak end of the double elbow and the anti-skid pattern. In view of this, the prior art does not disclose a forceps configuration that directly utilizes an archwire channel to insert the tip. In summary, the existing buccal tube technology is mainly focused on improvement of adhesive strength, archwire friction force and local form adaptation, but has significant defects in the aspects of impact-resistant structural design (such as streamline arc surface), operation convenience (plane clamping surface) and function integration (combination of traction hook and impact resistance). In addition, the existing buccal tube lacks of an adaptive design with a clamping tool (such as tweezers), the tweezers are easy to cause installation deviation due to mismatching of clamping surfaces, and meanwhile, the exposed layout of the traction hooks further increases the attack surface, so that impact resistance and patient comfort are affected. These drawbacks directly affect the effectiveness of the correction and patient comfort, and need to be optimized by structural innovation. Disclosure of utility model In view of the above problems, the utility model provides a low-resistance impact-resistant strip-shaped straight wire bow cheek tube, which mainly solves the problem that the traditional cheek tube is easy to fall off due to food impact, and a pair of strip-shaped straight wire bow cheek tube tweezers or pliers, which solves the problem that the traditional tweezers are easy to slip when used for
