Published:November 12, 2022DOI:https://doi.org/10.1016/j.ejwf.2022.10.003

      Highlights

      • Direct printing of a metallic appliance can be done using a completely digitalized process.
      • There exist operator and patient advantages when we utilize this process.
      • There exist some limitations and disadvantages to the process as well.
      • This technology allows taking the digitalization directly into the treatment process.

      ABSTRACT

      Orthodontic digitalization has progressed steadily. Recently, three-dimensional metal printing has revolutionized the way appliances are designed and manufactured. The process offers several advantages over the conventional analog process for both the orthodontic team and the patients. This article aims to explore the process of three-dimensional metal printing and give an insight into the advantages as well as potential limitations and disadvantages of this new technology.
