Comparative 1-Year Evaluation of 3D-Printed Resin Crowns Versus Monolithic Zirconia Crowns for Posterior Prostheses
This 1-year randomized controlled trial compares the clinical performance, wear, and fracture incidence of 3D-printed resin crowns and zirconia crowns in posterior tooth restorations, revealing acceptable adaptation but higher wear and fracture risk in resin crowns.
