The use of 3D printing technology can greatly improve the efficiency of diagnosis and treatment of many dental patients. After the doctor obtains the medical image data of the patient's teeth and gums through the scan, it is converted to 3D printing data for printing and molding, and processes such as sintering, dyeing, glazing, and polishing are performed to obtain a high-quality crown product. Printing efficiency and production efficiency are far greater than traditional cutting technology, easy to operate, and greatly reduce time and labor costs.
