Digital Workflows for Restoring Patient-Specific Implants and Digitally Designed Subperiosteal Implants

Classic subperiosteal implants (CSI) have been around for decades in the implant dentistry helping patients and surgeons especially with atrophic ridges. Since its introduction, there has been significant amount of development and researches around this technique. With the implementation of digital technology in oral surgery, there has been growing interest in revisiting CSI and developing patient-specific implants (PSI). Our goal is to provide a comprehensive overview of the evolution of subperiosteal implants and to address the treatment planning, design principles, and the fundamentals required for successful practice of PSI placement and restoration.
