Clinical Evaluation of Three-Dimensional (3D) Printing Resin Nanoceramic Crown Restoration.

This study aims to evaluate the function and aesthetics of ceramic-filled hybrid resin permanent crowns produced by 3D printing method in posterior teeth according to Revised FDI criteria. At the Department of Prosthodontics, Faculty of Dentistry, Ege University, 60 patients who present for single-tooth crown restoration in the posterior region of either the maxilla or mandible and who meet the inclusion criteria will receive a total of 60 permanent crown restorations. Following tooth preparation, the restorations will be fabricated using a three-dimensional (3D) printing technique with a ceramic-filled hybrid resin material (VarseoSmile TriniQ, Bego, Bremen, Germany). The effects of restorations on clinical success will be evaluated according to demographic data (age, gender, etc.) and modified USPHS and Revised FDI criteria, and statistical analysis will be applied to the recorded data. Follow-up visits are scheduled at 0: baseline, 6, and 12 months.
