Application of metal additive manufacturing in oral dentistry

With the progress of medical and health undertakings as well as the continuous deepening of attention to dental health, the dental implant has received extensive attention. It is an urgent need to resolve the problems of original manufacturing methods and processes in dental implant industry, such as complex manufacturing process, high production cost, and low biocompatibility. Recently, additive manufacturing has been considered as a promising technology of medical implant manufacturing with high efficiency, cost-effectiveness, wide applicability, and high accuracy. This paper briefly describes recent research and application progress of metal additive manufacturing in dental implants, in order to provide a clue and basis for maxillofacial joint, root, crown, etc.
