3D Metal Printing in Orthodontics: Current Trends, Biomaterials, Workflows and Clinical Implications

Three-dimensional (3D) metal printing of customized orthodontic appliances is at the cutting edge of orthodontic technology. Different additive techniques as well as materials have been employed in order to directly 3D metal print an orthodontic appliance. The potential advantages of 3D metal printed appliances include greater treatment efficiency, increased patient's comfort, reduced orthodontic appointments, reduced workflow steps, thus reducing the chances of error and resulting in a more accurate fit and better standardization. This article aims to describe the current trends, biomaterials, workflows and clinical implications of metal 3D printing, in order to aid clinicians in gaining some insight on this novel technology and to allow for greater incorporation in contemporary digital orthodontic workflows.
