Current and Emerging Applications of 3D Printing in Restorative Dentistry

Abstract

3D printing, or additive manufacturing, is an emerging technology in the dental field. As it continues to advance beyond diagnostic purposes, it shifts towards the fabrication of permanent prostheses utilizing existing and novel biomaterials. A review and comparison of the current research on materials, techniques, and applications of 3D printing available for restorative use was conducted. Currently, 3D printing used across the field of restorative dentistry, includes laboratory models and casting patterns, interim full and partial coverage restorations, surgical guides, occlusal splints, maxillofacial prosthetics, removable prostheses, and implants. Resins are most often used while ceramic and hybrid materials are currently under investigation and development. While the current research available highlights 3D printing’s potential in the dental field, more research is needed on the existing and developing materials and printers, thus allowing for an exponential increase of this technology’s applications in restorative dentistry.
