The Printed Promise From Innovation to Validation

Abstract

This editorial addresses the rapid integration of 3D printing (additive manufacturing) into restorative dentistry, highlighting a critical gap between technological enthusiasm and the supporting scientific evidence. The letter issues three primary calls to action for the dental community: 1) To prioritize long-term, in vivo clinical trials over purely laboratory-based (in vitro) studies; 2) To establish standardized, transparent protocols for printing and post-processing to ensure consistent and reliable outcomes; and 3) To accelerate the development of a new generation of high-performance, biocompatible materials that can rival conventional options. Ultimately, the editorial argues that for 3D-printed restorations to fulfill their transformative potential, the dental community must commit to a foundation of robust clinical evidence, collaborative standardization, and focused material innovation.
