In this work, the authors studied and compared the two main methods used in dental practice for the automated production of orthopedic structures: the widely used CAD / CAM milling method and the 3D printing technology.
As an object of research, temporary crowns were used, which were made on the basis of the same digital model:
a) by the method of CAD / CAM milling from polymethylmethacrylate disks;
b) by 3D printing from photopolymer resin based on LCD technology.
Comparison of production methods and finished designs was carried out according to the following characteristics: strength, durability, aesthetic qualities, accuracy of orthopedic designs, etc.
According to the results of the study, it was concluded that 3D printing can be a good alternative to CAD / CAM milling in solving problems of temporary prosthetics.
