Abstract

The utility model relates to a tooth-correct rectangular wire. The square wire covers an isolated film coating with the thickness of 2-3 mu m on the surface of a Ni Ti alloyed rectangular arch wire, so the metal of Ni Ti alloyed rectangular arch wire does not expose. The covered isolated film layer is a TiO2 ceramic coating. The utility mode is smooth in the surface and very beautiful; the original performance of the Ni Ti alloyed rectangular arch wire is kept without any changing, such as its elastic performance and its formability. The covered isolated film coating prevents human body from the harm causing by the metal parts directly contacting human body and precipitating Ni ion and therefore improve the biocompatibility between the material and human body and the teratogenic and carcinogenesis of the harmful metal ion.

Description

Orthodontics side's silk

One, technical field: this utility model relates to a kind of orthodontics side's silk of orthodontic treatment usefulness.

Two, background technology: at present to rectify the type square arch wire be the square arch wire with flexibility and formability to the tooth of the NiTi alloy that uses, but since the NiTi alloy can be under the effect of body fluid Ni ²⁺Separate out, cause human body is produced the effect of carcinogenic teratogenesis, tackle human body mutually and produced certain secondary face sound.

Three, summary of the invention:

1, goal of the invention: this utility model provides a kind of orthodontics side silk, and its purpose is to solve the tooth of the NiTi alloy of traditional use and rectifys the type arch wire, directly contacts human body, because the NiTi alloy can be separated out Ni under the effect of body fluid ²⁺, cause problem to aspects such as the carcinogenic teratogenesis side effect existence of human body.

2, technical scheme: this utility model is achieved through the following technical solutions:

A kind of orthodontics side silk is characterized in that: this side silk is that surface coverage one layer thickness at NiTi alloy square arch wire is the separating film layer of 2～3 μ m, and the metal of NiTi alloy square arch wire is not exposed.

The separating film layer that covers is TiO ₂Ceramic film.

3, advantage and effect: by the enforcement of technical solutions of the utility model, the strong type square arch wire of NiTi alloy tooth that can solve the tradition use well directly contacts human body, because the NiTi alloy can be separated out Ni under the effect of body fluid ²⁺, cause problem to aspects such as the carcinogenic teratogenesis side effect existence of human body.This utility model is at the NiTi alloy square arch wire surface coverage one deck separating film layer as metallic matrix, and outward appearance is that the metal Asia is photochromic, and the material of the separating film layer that covers is TiO ₂Ceramic material, thickness is 2～3 μ m, this thickness is tested repeatedly through the inventor and is drawn, promptly guaranteed original performance of NiTi alloy square arch wire such as elastic performance and plastic performance, also stoped metal part directly to contact and separated out the harm that Ni ion pair human body causes, improved the biocompatibility between material and the human body and the teratogenesis carcinogenesis of harmful metal ion with human body, guaranteed the ruggedness of product simultaneously, should rectify type side's silk smooth surface, attractive in appearance, easy to use.

Four, description of drawings: accompanying drawing 1 is this utility model structural representation;

Accompanying drawing 2 is the structure for amplifying sketch map of Fig. 1.

Five, the specific embodiment:

Embodiment 1:

Shown in accompanying

drawing

1,2, this utility model orthodontics side silk is the orthodontics side's silk with bionical Ti-O overlay film that a kind of orthodontic treatment is used.NiTi alloy square arch wire 1 surface as metallic matrix that should rectify type side's silk utilizes vacuum magnetic-control sputtering to cover one deck separating film layer 2, and outward appearance is that the metal Asia is photochromic, and the material of the separating film layer 2 that is covered is TiO ₂Ceramic material, the TiO of formation ₂The thickness of ceramic film is 2～3 μ m, and this thickness had both guaranteed this strong type side silk smooth surface, and was attractive in appearance, also kept the original performance of NiTi alloy square arch wire, as elastic performance and plastic performance, can not influence result of use.This separating film layer 2 has stoped well also metal part and human body directly to contact to cause that Ni is ionic separates out the harm that human body is caused simultaneously, makes Ni ²⁺Contact human body never, improved the biocompatibility between material and the human body and the teratogenesis carcinogenesis of harmful metal ion, become a kind of tooth square arch wire of strong type instrument-overlay film functional, safe in utilization therefrom.

Claims

1, a kind of orthodontics side silk is characterized in that: this side's silk is that surface coverage one layer thickness at NiTi alloy square arch wire (1) is the separating film layer (2) of 2～3 μ m, and the metal of NiTi alloy square arch wire is not exposed.

2, according to the silk of the orthodontics side described in the claim 1, it is characterized in that: the separating film layer that covers (2) be TiO ₂Ceramic film.
