A Fully Digital Workflow for Jaw in a Day Reconstruction Utilizing a Novel Patient-specific Scan Body and Outsourced...

In the traditional jaw in a day technique, discrepancies between the virtual surgical plan and final implant positions are accommodated by creating oversized access openings in the prefabricated prosthesis, allowing passive adaptation around implant cylinders before registering definitive implant positions with autopolymerizing or light-curing resin. Utilizing digital scanning and 3-dimensional printing, a direct-to-multiunit abutment dental prosthesis can be fabricated as a fully digital alternative to this analog method. Although direct-to-multiunit abutment connections have been reported in head and neck reconstruction using the IPS Preprosthetic System, their application in jaw in a day has not been previously described. This digital workflow eliminates restorative materials unsuitable for the operative environment, maintains sterility, simplifies intraoperative handling, and enhances mechanical integrity through minimized access openings. Moreover, it transfers prosthetic fabrication to the dental laboratory, allowing concurrent production during surgical reconstruction and enabling immediate intraoperative delivery.
