Overview

Scoping review demonstrates technical feasibility but uncertain clinical durability for 3D-printed ceramic and resin definitive restorations, highlighting the necessity of long-term trials.

Key Points

Map available evidence on additive manufacturing technologies and 3D-printed resin- and ceramic-based materials used for definitive tooth-supported dental restorations.
Conducted a scoping review following JBI methodology and PRISMA-ScR guidelines across MEDLINE, Embase, and Scopus from inception to April 2026.
Identified and descriptively charted data from 111 eligible studies evaluating restoration types, materials, additive manufacturing technologies, and physical or clinical outcomes.
Evidence derived almost exclusively from in vitro testing (105 of 111 studies), with only six clinical evaluations including a single randomized controlled trial.
Printed zirconia consistently demonstrated marginal fit, internal fit, and fracture resistance within clinically accepted thresholds reported by primary studies, whereas printed resins were constrained by lower strength and color instability.
Material performance and mechanical outcomes depended strongly on processing parameters, indicating a critical need for workflow standardization.
