Embodiment 1

[0028] Colorful orthodontic brackets with rainbow effect: The brackets are made of pure titanium grade TA2, and bracket blanks of various tooth positions are prepared according to the route of cutting-forming-welding-polishing-cleaning. The bracket is colored by anodic oxidation method, the electrolyte temperature is 18°C, and the electrolyte is 0.5mol / L H 2 SO 4 +0.5mol / L HCl+deionized water, the oxidation time is 10min, and the brackets of different tooth positions are anodized according to the process parameters in Table 1.

[0029] The process of anodic oxidation reaction is:

[0030] Ti → Ti 2+ ;

[0031] 2H 2 O→O 2 +2H 2 ;

[0032] Ti 2+ +2O 2- →TiO 2 ;

Abstract

The invention belongs to the technical field of orthodontics, and in particular relates to a color metallic orthodontic bracket as well as a manufacturing method thereof and a composite structure. The orthodontic bracket is manufactured by using titanium-based metals; the titanium-based metals are subjected to material cutting, formation, welding, polishing, cleaning and anode oxidization so that the outer surface of the manufactured orthodontic bracket is colored. By using the titanium-based metals with high biological performance, the titanium-based metals are suitable for environment of the oral cavity, so that the risk of anaphylaxis on a human body caused by nickel ions which are separated out in a traditional stainless steel bracket is avoided. According to the color metallic orthodontic bracket, a personalized dental aesthetic demand of a patient can be fully met; under the combination of the color metallic orthodontic bracket and a digital design technology of a current initial oral cavity aesthetics, the communication among patients, doctors and technicians can be effectively improved, and an application range of a titanium-based material surface anode oxidization technology on orthodontic appliances can be widened.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and in particular relates to a colored metal orthodontic bracket, a preparation method and a combined structure thereof. Background technique [0002] Orthodontic brackets are an important part of fixed appliances. Clinically, the brackets are required not only to have good mechanical properties and low friction, but also to have good biocompatibility, comfort and appearance. With the changes of the times, patients have higher and higher requirements for the aesthetics of brackets. Today's young people pay more attention to personalization, and to adapt to it, the concept of personalized aesthetic dental treatment has emerged, and colored brackets and colored dental arch wires have appeared in orthodontic materials. [0003] There are two ways to obtain colored brackets. One is colored plastic brackets, which have poor mechanical properties, are easy to fall off, and have poor correction e...
