3D printing technology is a natural match for the dental industry. First of all, based on the differences in the characteristics of the teeth of each patient in the dental industry, the generated three-dimensional data are also different, and the application of 3D printing technology can achieve personalized production. Secondly, the structure of human teeth is relatively complex. Traditional manual labor will cause deviations in the accuracy of dental medical products and cause discomfort for patients. 3D printing technology meets the needs of precise, complex and tailor-made dentistry. Finally, dental patients always hope to be able to get fast and effective treatment, the traditional processing method is slow, and 3D printing technology can accelerate the progress of the treatment process. The application of 3D printing technology in the field of dental restorations mainly includes dental implants, removable dentures and appliances.
