For quite some time, the computer assisted modelling and manufacturing (CAD/CAM = computer aided design/computer aided manufacturing) has spread in the world of dentistry. Starting from this innovation, the digital workflow was established as a desirable principal. The acquisition of patient situations via oral or lab scanners, the modelling of restaurations with adapted software, and the manufacturing via CNC-milling are state of the art. In addition to milling, additive manufacturing has found its way into dental practices and orthodontic laboratories as an emerging technology. In most cases, lithography-based methods are used for models and casting molds. This article is intended to give a survey of the additive manufacturing technologies that—in principle—are suitable for the dental field. Additionally, applications are listed, and in the last section, we give an outlook on future developments.
