To have a beautiful smile, neat and beautiful teeth are indispensable. Now, invisible orthodontic appliances using dental 3D printer technology are rapidly popularized and have become the first choice for many patients who need dental correction. According to the statistical data, the global market of invisibility orthotics will reach 18.2 billion yuan in 2026.

Invisible orthodontic appliances are beautiful and convenient. Many people can't wear steel braces because of their occupation or various reasons. Orthodontists will recommend the use of invisible orthodontic appliances. The integrated service provider of invisible orthotics is also gradually mature, and the integrated process from diagnosis, treatment to orthotic production brings patients a more comfortable experience.

The invisible orthodontic technology is inseparable from 3D printing technology. Whether it is the 3D dynamic design software when designing the correction scheme or the 3D printing machine when making the dental model, it is 3D technology. The development of bracket free invisible orthodontic technology in the past 20 years is completely based on 3D printing technology. The precise tooth models required for invisible braces are made on the basis of the maturity of 3D printing technology. Firstly, the dental model is printed out with a dental 3D printer, and then the invisible braces are made by thermoforming technology.

Generally, a patient needs to use about 30 ~ 40 invisible orthotics, which can achieve the desired correction effect by continuously exerting slight pressure on the teeth. So much demand for braces means that the same number of tooth models need to be printed, and there are only small differences between each model. If you want to customize and mass produce orthotics for patients in a short time, it is impossible to use traditional manufacturing methods. 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.

The correction process of invisible orthodontics is generally divided into indirect method and direct method. You can use the direct method process. First, obtain the patient's oral data through oral scanning - design an exclusive correction scheme - print dental Molds - hot pressing to manufacture invisible appliances.

The purpose of obtaining 3D data information of teeth is to facilitate the design of correction scheme in 3D model software. When acquiring data, the doctor will directly put the optical scanning head of the intraoral scanner into the patient's mouth to directly scan and obtain the information of the patient's teeth, mucous membrane and other soft and hard tissues.

After the exclusive orthodontic scheme is determined, the manufacturer obtains the model data required for each stage of orthodontic dental mold. After printing these dental molds, we can get the "mold" that can make invisible orthotics.
