Transition of failed cement-retained prosthesis to screw-retained implant prosthesis

Abstract

Prosthesis failures in cement-retained implant restorations can be managed by transforming the restorations into screw-retained prosthesis to meet the current implant treatment philosophies for large full-arch reconstructions. The challenges involved in this case report multiplied due to unavailability of components for older systems of implants and had to be managed with a framework which permits engagement of implant and abutment level connection simultaneously. The case report highlights the transition of failed cement-retained prosthesis to screw-retained prosthesis for predictable future retrievability and enhanced clinical performance.
