The Use of 3D Printers in Orthodontics - A Narrative Review

Abstract

Developments in computer-aided design and three-dimensional (3D) printing have revolutionized the workflow for orthodontic applications. The purpose of this review article is to provide information about 3D printer history and types, appliances manufactured using 3D printers, and new designs that can be used in different cases. Articles published between January 2010 and November 2020 were reviewed on PubMed, MEDLINE, ScienceDirect, Elsevier, and Google academic resources, and 69 were identified as appropriate for the study. It was seen that bracket and archwires, nasoalveolar molding devices, orthognathic surgical splints, removable appliances, expansion appliances, clear aligner, retainers, auxiliary attachments, and working models can all be made with 3D printers. The 3D printer is now a technology that is easily accessible to orthodontists, increasing the production of different customizable appliances and promising a transition to a digital clinical workflow in the future.
