Clinical Challenges of Castless, Componentless Full-Arch Implant Supported Zirconia Prosthesis
Carlos Castro, DDS, FACP
Duluth, GA

Various technologies have recently been shown to be effective in obtaining impressions for full-arch implant restorations. While digital processes have simplified laboratory procedures, the castless workflow has introduced some challenges, such as model verification, layering of ceramics, and TiBase abutment cementation. This presentation will describe the challenges in a step-by-step manner, from data acquisition to fabrication and insertion of a full-arch implant-supported zirconia prosthesis.

At the conclusion of this session, attendees should be able to:

• Compare analog and digital workflows used for fabrication of full-arch zirconia prostheses.
• Identify potential steps at which introduction of errors and dimensional distortion could occur.
• Introduce a clinical protocol adjusted for minimal fabrication errors and maximum efficacy.
