3D Printing in Digital Prosthetic Dentistry: An Overview of Recent Developments in Additive Manufacturing

Josef Schweiger et al. J Clin Med. .

Abstract

Popular media now often present 3D printing as a widely employed technology for the production of dental prostheses. This article aims to show, based on factual information, to what extent 3D printing can be used in dental laboratories and dental practices at present. It attempts to present a rational evaluation of todays´ applications of 3D printing technology in the context of dental restorations. In addition, the article discusses future perspectives and examines the ongoing viability of traditional dental laboratory services and manufacturing processes. It also shows which expertise is needed for the digital additive manufacturing of dental restorations.

Keywords: 3D printing; 3D printing using composite resin; 3D printing using zirconia; digital one-piece casting; digital pressing technology; graphic 3D models; hybrid production; multi-material 3D printing.
