The successful application of 3D printing technology in the orthodontic industry is the inevitable result of the deep penetration of information technology and digital technology into the traditional manufacturing industry. In the process of orthodontic treatment, gypsum model is usually used. Because the material stiffness of gypsum model is low, it will be affected by many factors in the application process, resulting in model damage. At this stage, with the improvement of 3D printing technology, the 20-year development history of oral invisible correction (bracket free invisible correction) is completely based on 3D technology. It is precisely because of the rapid development of digital model that the level and accuracy of orthodontic treatment are continuously improved. Therefore, digital model will be a great development trend in the future.
With the continuous development of economy and the increasing progress of science and technology, 3D printing technology plays a very important role in the process of orthodontic treatment. It can not only greatly reduce the treatment cycle, but also be customized, which improves the patient's satisfaction and comfort in all aspects. To a certain extent, it improves the treatment efficiency and service quality of doctors, and brings great help and support to the rapid development of orthodontic treatment.
It is both a bright spot and a pain point. At present, the development of technology still can not match the needs of users. 3D printing technology also has many limitations, such as:
(1) Productivity issues
At present, most of the 3D printers in the orthodontic industry still have the problem of low efficiency. After each version is finished, it is necessary to manually shovel parts for recycling, and assign special personnel to watch the 3D printer, which consumes a lot of labor.
(2) Accuracy problem
For the surface treatment of 3D printing products, different 3D printers have different processing accuracy, but the demand of customers is higher and higher, and their requirements for accuracy are higher and higher.
(3) Material problem
Material is one of the main factors restricting the rapid development of 3D printing technology and its rapid integration with various industries. Different industries have different requirements for materials, such as temperature, strength, toughness, precision, etc. Due to the product characteristics of the orthodontic industry, the requirements for materials are very strict. The market urgently needs to develop materials suitable for the industry.
