Clinical Evaluation of Prefabricated Versus 3D-Printed Composite Resin Veneers: in Vivo Study

Dental veneers are now a commonly used conservative treatment to improve the appearance and functionality of anterior teeth that have enamel flaws, diastemas, small abnormalities, and discoloration. Compared to ceramic veneers, composite resin veneers have a number of benefits, such as requiring less tooth preparation, being less expensive, being easier to repair, and requiring less chairside time. Recent developments in composite resin technology and adhesive dentistry have further enhanced their mechanical qualities, wear resistance, and aesthetic results, making them a desirable treatment option for patients and professionals alike. There is little clinical data that directly compares the long-term performance of prefabricated and 3D-printed composite veneers, despite their growing use. The majority of research that is currently available has either examined each technique separately or has concentrated on laboratory assessments of mechanical properties. As a result, there is still not enough data to compare their clinical behavior in intraoral settings.
