This course explores the transition to fully metal-free full-arch zirconia restorations by eliminating the use of Ti-bases and adopting advanced screw systems that connect directly to multi-unit abutments (MUAs). Attendees will learn about the common challenges with traditional hybrid designs — such as debonding, broken Ti-bases, and excess prosthetic thickness — and how going metal-free can streamline restorative workflows, improve long-term outcomes, and simplify maintenance. The session will also include an in-depth look at various screw systems that enable direct-to-MUA connections and offer angle correction capabilities. These systems not only eliminate the need for Ti-base copings but also enhance access hole positioning and esthetics.

Presenter
Learning Objectives
- Identify the clinical and technical drawbacks of using Ti-bases in full-arch restorations, including bonding failures, fractures, and increased complexity in prosthetic design.
- Review the benefits of using direct-to-MUA screw systems for full-arch zirconia, including improved mechanical stability and reduced restorative thickness.
- Discuss the available screw-retained systems that support angle correction, and how these systems optimize access hole positioning and enhance restorative versatility.
- Analyze digital workflows and material considerations when designing and delivering metal-free full-arch restorations, from milling to final placement and maintenance.
