Abstract

The invention provides a multifunctional micro-implant anchorage nail and a design and manufacturing method thereof. The anchorage nail comprises a nail body with a tip end, threads are arranged on the nail body, an auxetic micropore structure area is arranged on one side of the nail body, and a non-auxetic micropore structure area is arranged on the other side of the nail body. An auxetic and non-auxetic microporous structure is introduced into the design of the anchorage nail body, and due to the design, when the nail body is bent and deformed under the action of tangential distraction orthodontic force, the tension side is subjected to auxetic deformation, and the compression side is subjected to compression expansion deformation, so that the anchorage nail is subjected to expansion deformation under the action of the orthodontic force; and the in-vivo stability is improved. When the anchorage nail needs to be dismantled, an anti-orthodontic force opposite to the traction force in direction is applied to the nail body, so that the anchorage nail is reversely bent, the pulled side of the anchorage nail is subjected to pulling contraction deformation at the moment, the pressed side of the anchorage nail is subjected to pressing contraction deformation, compression deformation is integrally achieved, and the nail body is easy to remove.

Description

technical field

[0001] The invention relates to the technical field of orthodontic appliances, in particular to a multifunctional micro-implantation anchorage nail and its design and manufacturing method. Background technique

[0002] Orthodontic treatment is to adjust the coordination between the upper and lower jaws, between the upper and lower teeth, and between the teeth and the jaws through orthodontic devices, and finally achieve the balance, stability and beauty of the oral and jaw system. During the treatment process, the orthodontic treatment mainly relies on wearing orthodontic appliances inside or outside the oral cavity, and exerts appropriate force on the teeth, alveolar bone and jawbone to make them move physiologically, thereby correcting the malocclusion. According to the theory of mechanical balance, any force applied to the treated tooth to make it move must simultaneously produce a force in the opposite direction and the same magnitude, and the situation t...

Embodiment Construction

[0026] This embodiment provides a multifunctional micro-implant anchorage nail for orthodontic treatment, such as figure 1 with figure 2 As shown, the anchorage nail 1 is composed of a nail body 13, a neck column portion 12, and a top cap 11. The top cap 11 is connected to the nail body 13 through the neck column portion 12, and the nail body 13 is far away from the neck column. One end of the portion 12 is provided as a tip 14 .

[0027] The anchorage nail 1 in this embodiment is provided with a microporous structure in the nail body, such as image 3 As shown, the microporous structure is distributed in the whole nail body; as an optional embodiment, the microporous structure may also be distributed only in the surface part of the nail body. The thread of the nail body 13 can adopt a structure with holes or a solid structure without holes. Such as figure 1 As shown, the anchorage nail 1 will be subjected to the tangential orthodontic force of the spring 2 and / or the tra...
