Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oral orthodontics, in particular to an invisible correction prefabricated attachment device for controlling the root movement of auxiliary teeth in the mesiodistal direction. Background Art
[0002] Invisible orthodontic technology can increase the undercut shape of the tooth surface by bonding accessories, and increase the retention of the invisible braces, which is especially suitable for cases with small crowns and small undercut shapes. Invisible orthodontic technology is difficult to control the parallel movement of teeth in the mesiodistal direction, especially for cases with short crowns. The undercuts are small and the retention force is insufficient, which cannot fully express the invisible braces data and cannot meet clinical requirements. For the existing problems of invisible orthodontics, doctors now usually make traction hooks next to the chair to reduce the force height and make the force line pass through the impedance center as much as possible.
[0003] However, the existing production process takes a long time, and the metal hooks that rely on resin bonding are easy to fall off, requiring emergency follow-up visits, which brings inconvenience to patients and doctors. In addition, the existing metal hooks are short in length and cannot meet the root control requirements. After production, the fixing parts originally bonded to the tooth surface will be damaged, causing the braces and the tooth surface to not fit well. Utility Model Content
[0004] In view of the above problems in the prior art, the utility model provides a prefabricated invisible orthodontic accessory device for controlling the root movement of auxiliary teeth in the mesiodistal direction, which is achieved through the following technical solutions:
[0005] A prefabricated invisible orthodontic accessory device for controlling root movement of auxiliary teeth in the mesiodistal direction comprises a base plate and a traction arm. A metal retaining accessory is installed on the surface of the base plate. The traction arm is fixed to the bottom of the metal retaining accessory. A traction hook is provided at one end of the traction arm away from the metal retaining accessory.
[0006] The utility model is further configured as follows: the bottom plate is welded to the metal fixing attachment, and the metal fixing attachment is welded to the traction arm.
[0007] The utility model is further configured as follows: the first form of the metal retaining attachment is designed as a cube that is long in the occlusal direction of the teeth (gingiva), and the second form of the metal retaining attachment is designed as a cube that is long in the mesiodistal direction.
[0008] The utility model is further configured as follows: the traction hook is in an I-shape, and a traction groove is formed between two horizontal plates of the traction hook.
[0009] The utility model is further configured as follows: the bottom plate is made of metal, the bottom plate is arranged in a curved surface, and the back side of the bottom plate is roughened.
[0010] In summary, the beneficial technical effects of the utility model are:
[0011] The shape of resin attachments is simulated by metal retention attachments and base plates. The prefabricated device is bonded before the oral digital data is collected. The produced invisible orthodontic appliance has corresponding attachment grooves to match the device. The root movement of the teeth is controlled through the traction grooves, and there is no need for complex clinical operations such as resin and metal hook bonding and traction, which avoids damage after bonding to the tooth surface. By roughening the back of the base plate, the bonding area is increased, making the base plate and the tooth surface bonded more firmly. BRIEF DESCRIPTION OF THE DRAWINGS
