Résumé
Prosthodontic dentures are used to treat tooth defects,dentition defects and dentition loss,which can restore the appearance and function of the patient's oral cavity.With the advent of the digital age,3D printing technologies have slowly gained widespread popularity.In the field of prosthodontics,3D printing can manufacture materials including resins,waxes,metals,and ceramics.Besides,it can produce fixed,movable,implant dentures and dental models required for dentures.3D printing can produce complicated things with a high material consump-tion rate,simplifying denture manufacture.In addition,the accuracy of 3D printed prosthesis is directly related to the comfort and durability.This article summarizes the process of accuracy of 3D printed dental prosthesis at home and abroad in recent years and provides clues for better 3D printing application.
