Abstract

This lecture explores the revolutionary impact of 3D printing technology in modern dental practice, presenting evidence-based insights into its advantages, limitations, and clinical applications. As 3D printing continues to transform restorative and prosthetic dentistry, clinicians need to understand both the scientific principles and practical considerations behind this emerging technology.

The presentation will address three critical questions: WHY adopt 3D printing, HOW to implement it successfully, and WHAT clinical applications are most promising. We'll examine how 3D printing offers distinct advantages over traditional milling techniques, including the fabrication of complex geometries, thinner restorations, reduced material waste, and potential cost savings.

Evidence-based guidelines will be provided on selecting appropriate 3D printers and resins, optimizing printing parameters, and implementing post-processing protocols. Special attention will be given to critical factors affecting clinical success, including material selection, restoration thickness, build orientation, and surface finishing techniques.

The lecture will showcase clinical applications across various restoration types, from single-unit crowns and veneers to dentures, splints, and implant-supported prostheses, with a focus on fabrication accuracy, fit, mechanical properties, color stability, and long-term performance. Case presentations will illustrate successful implementation strategies and clinical outcomes.

Current limitations will be addressed, including contraindications for parafunctional habits, restrictions on cantilevers, and considerations for interocclusal space. The presentation will conclude with a clear take-home message on when and how to incorporate 3D printing into daily practice, offering attendees practical guidance on material selection, processing parameters, and clinical protocols to achieve predictable, high-quality results in this rapidly evolving field.
