AI Technical Summary
In existing technologies, the attachments of invisible braces are not firmly bonded and are prone to falling off, which increases the clinical operation time of orthodontics and affects the treatment process. In addition, traditional tools have poor clamping effect and pose a risk of scratching the oral mucosa.
An auxiliary accessory bonding device was designed, including a transparent box-shaped head and a handle, containing an elastic support component. The movable cover plate is kept in position by the reverse force of the elastic support component. The transparent structure facilitates light curing and provides a stable bonding effect.
It improves the adhesion strength and operational efficiency of attachments, reduces the risk of detachment, minimizes damage to the oral mucosa, and simplifies the operation process.

TECHNICAL FIELD
[0001] The utility model relates to the field of tooth correction, especially to an auxiliary attachment bonding device. BACKGROUND
[0002] The invisible aligner is a transparent tooth aligner customized for patients based on 3D printing technology. The invisible aligner needs to be used in cooperation with an auxiliary device, i.e., an attachment, when being worn, so as to achieve the best state of correction force. The attachment is a small protrusion bonded on the teeth, which is made of light-cured resin with a color close to that of the user's teeth by a doctor in the clinic and bonded on the teeth through an attachment template. The attachment, like a small dowel, is located on the surface of the teeth and is a core component for controlling the precise movement of the invisible aligner and an indispensable part. If the attachment is not firmly bonded, it is easy to fall off during the removal of the attachment template or the daily wearing of the patient. On the one hand, re-bonding the attachment will increase the chair-side operation time of the orthodontic clinician and reduce the efficiency of the medical examination. On the other hand, the falling off of the attachment during the treatment process will affect the correction process, increase the number of patient restarts, and thus prolong the correction time. Therefore, when bonding the attachment, the doctor usually uses a forceps to press the attachment template and the tooth surface tightly, but the forceps is not a special pressing tool, the pressing effect is not good, and it is also easy to block the light source and has the risk of scratching the patient's oral mucosa. SUMMARY
[0003] To solve the above problems existing in the prior art, the utility model provides an auxiliary attachment bonding device, which comprises a head and a handle connected together, the head is a transparent box-shaped structure, and contains an elastic supporting part, one end of the elastic supporting part is fixed to the bottom surface of the box-shaped structure, the other end is fixed to a movable cover plate of the box-shaped structure, the movable cover plate can move in the space from the bottom to the top of the side wall of the box-shaped structure, and the top edge of the box-shaped structure is provided with a blocking piece.
[0004] The outward pushing force provided by the elastic supporting part makes the movable cover plate at the top end of the box-shaped structure, and when the movable cover plate is pressed inward, the elastic supporting part will be compressed and generate a reverse force to maintain the position balance of the movable cover plate.
[0005] Further, the blocking piece can prevent the movable cover plate from coming out of the box-shaped structure, which can be a protruding sheet.
[0006] Further, the box-shaped structure is made of a high-transparency material, and the light of the light-cured lamp can pass through.
[0007] Preferably, the box-shaped structure is a cuboid; or in some cases, the cross section of the box-shaped structure is an ellipse.

Further, the handle is connected with the head through a steering head, which can be steered along the middle vertical plane or can be steered arbitrarily. Still further, the steering head has a retaining buckle, which can be fixed at a suitable rotation angle.
[0010] Preferably, the head is detachable, and the head is designed with different sizes or shapes and can be replaced.
[0011] In a preferred embodiment of the utility model, the handle has a curved neck similar to a curved forceps, which is convenient for the doctor to hold.
[0012] In another preferred embodiment of the utility model, the handle has a fold line neck similar to a toothbrush, which is convenient for positioning the buccal surface of the teeth on both sides.
[0013] Preferably, the elastic supporting part is a spring. Further preferably, the coil range of the spring is greater than the periphery of the accessory, and is preferably greater than the periphery of the accessory by not more than 1mm, which can compact the accessory.
[0014] Preferably, the spring shape is consistent with the head shape, closely adheres, and has no obstruction.
[0015] In a preferred embodiment of the utility model, the spring has a square or approximately square spiral structure rotating along the inner wall of the box-shaped structure.
[0016] In a preferred embodiment of the utility model, the contact surface of the movable cover plate and the elastic supporting part is provided with a groove for mutual positioning.
[0017] The auxiliary accessory bonding device uses the handle held by the doctor, and the head is pressed against the template surface around the accessory. Since the accessory part is relatively prominent, the movable cover plate is pushed in, and the elastic supporting part is compressed, thereby applying a counterforce to the accessory, so that it is firmly bonded to the tooth surface.
[0018] Preferably, the bottom surface of the box-shaped structure is 1.5-3mm long.
[0019] Preferably, the length of the handle is 8-10cm.
[0020] Preferably, the auxiliary accessory bonding device provides different specifications according to the size and different positions of the accessory, such as three models of large (L), medium (M) and small (S) can be set.
[0021] The auxiliary accessory bonding device of the utility model has simple structure, convenient to use, the edge of box-like structure buckles around the accessory, which is fixed and not displaced, the elastic supporting part firmly supports the accessory through rebound force, the transparent head part can make the light of light curing lamp pass through, so that the bonding is more firm. According to the position and size of the accessory, the utility model can design products of different shapes and sizes.
