When you smile, do you want to have white, neat and beautiful teeth? I believe this is what most beauty lovers hope, so many beauty institutions in the market have begun to provide orthodontic services. According to relevant surveys, the global market of invisible orthodontic appliances for orthodontics will reach US $8.2 billion by 2026.

As for the current oral medicine with digital medical technology, the production of invisible orthodontic appliances, whether it is the 3D dynamic design software of correction scheme or the professional dental 3D printer used to make dental molds, can be said to be inseparable from 3D printing technology. Generally speaking, a scheme that needs to correct teeth needs about 30 to 40 orthotics, and these orthotics need to be used. The expected correction effect can be achieved by continuously applying slight pressure on the teeth.

However, due to the short time interval between the replacement of orthotics and the deviation of the data after each correction, it is necessary to customize the orthotics for patients in a short time and mass produce the orthotics, which can not be realized by using the traditional production method. As a digital forming technology, 3D printing technology has the characteristics of accurately transforming digital design into physical objects, which perfectly meets the requirements of personalized and mass production. Dentists only need to scan a circle in the patient's mouth with a 3D scanner to obtain accurate digital data of the patient's teeth, mucous membranes and other soft and hard tissues.
