Frameworks for All-on-4 implant-supported prostheses can be fabricated using a variety of materials. Traditionally, these frameworks were cast from noble metals like gold or base metal alloys such as Chromium-cobalt, since the introduction of CAD / CAM we can now use materials with additional advantages such as Zirconia and Trilor.
The article compares the fracture load of two framework materials, zirconia and a new fiber-reinforced composite (FCR Trilor), for full-arch implant-supported rehabilitations using various cross-sections.
