Milled cobalt-chromium metal framework with veneered porcelain for a complete-arch fixed implant-supported prosthesis: A clinical report

摘要

Many materials have been introduced for the fabrication of complete-arch fixed implant-supported prostheses. This clinical report demonstrates the use of a computer numerically controlled (CNC), milled, 1-piece cobalt-chromium framework with veneered porcelain to treat a patient with dental implants placed with limited prosthetic space. This prosthodontic option combined the advantages of a digitally manufactured solution for a 1-piece metal framework and the excellent track record of metal-ceramic prostheses. An additional advantage of this option is its use in situations with reduced prosthetic space, where alternative materials such as monolithic zirconia are contraindicated.
