DEVELOPMENTS IN 3D PRINTING: TRANSFORMING IMPLANTS AND DENTAL PROSTHETICS

Abstract

Aim
This study compared the clinical performance of 3D-printed prostheses and implant-supported restorations to conventional fabrication techniques and CAD-CAM milling in a hospital scenario.

Methodology
50 patients were divided into three groups at random: 15 received CAD-CAM, 15 received traditional methods, and 20 received 3D printing. Measured outcomes included marginal fit, fabrication time, patient satisfaction, and complication rate over a 12-month period.

Results
With the lowest marginal discrepancy (52.7 µm), the shortest fabrication time (4.2 h), the highest patient satisfaction (VAS 9.2), and the lowest complication rate (5%), 3D-printed restorations outperformed CAD-CAM and conventional techniques.

Conclusion
3D printing demonstrated superior accuracy, efficiency, and patient-centered outcomes when compared to CAD-CAM and conventional fabrication. Additive manufacturing offers a reliable alternative to modern restorative methods.
