Additive Manufacturing in Dentistry - A Contemporary Review

Introduction: Nowadays the additive technologies have become an integral part of every industry all over the world, including healthcare and dentistry, as they have been developing with unusual speed. In order to be resolved key issues many new technological approaches were developed. Methods: Key publications in English from past two decades are surveyed. Results: The additive processes allow layered fabrication of complex objects. Technologies such as: Vat polymerization, Powder bed fusion, Material extrusion, Binder jetting, Material jetting can be used in dentistry for fabrication of custom implants, apnea appliances, occlusal splints, surgical guides, complete dentures, crowns, bridges, RPD frameworks, or their prototypes. Other types as Direct energy deposition and Sheet lamination are not directed to the medical or dental branches at present. Conclusion: The additive manufacturing is developing incredibly fast and today it is used in almost every stage of the production process in dentistry, often than ever. During the past few years the process of 3D printing has become more accurate, fast and accessible, but there is still need to be optimized.
