Abstract: The all-porcelain restoration is highly favored by patients due to its good biocompatibility，aesthetic and mechanical properties，and has become the mainstream method of fixed restoration. The technology of subtractive manufacturing（SM）represented by numerical control cutting and equivalent manufacturing（EM）represented by losing wax casting have developed well，but there are still some shortcomings. With the advent of the era of digitalization，porcelain prostheses，removable partial denture and implant guide manufactured by 3D printing technology have been applied clinically；however，3D-printed all-ceramic restoration is still in the research stage. In this paper，the working principle，research status，advantages and disadvantages of various 3D printing ceramic technologies will be briefly introduced，and their development will be prospected.
