Abstract
This multicenter study evaluated the clinical usefulness of digital complete denturesfabricated with 3D printing technology. 38 edentulous patients were assessed at baseline,immediately after delivery, and at 1, 3, and 6 months using the Barthel Index (BI), OHIPEDENT-J, and EQ-5D-5L. Dentures were produced by combining CAD-designed, highprecision3D-printed bases with prefabricated full-arch artificial teeth. BI scores showed nosignificant differences, confirming that daily living activities were maintained. OHIP-EDENT-Jdemonstrated significant improvements at 1 and 6 months, particularly in functional limitation,psychological discomfort, and handicap domains. EQ-5D-5L revealed short-term improvementsin health-related quality of life, suggesting systemic effects beyond the oral region. This techniqueimproved fabrication accuracy, efficiency, and turnaround time compared with conventionalmethods, offering an effective solution amid concerns about dental technician shortages. Overall,3D printing-based denture fabrication demonstrated functional stability, durability, and patientsatisfaction, highlighting its potential as a valuable therapeutic option.
