Management of a Fractured Multiunit Maxillary Implant‐Supported Fixed Prosthesis with Stripped Abutment Screws Using a Hybrid Cement‐Retained and Screw‐Retained Design: A 5‐Year Follow‐Up Clinical Report

Fracture and loosening of implant‐supported prostheses (ISPs) are complications encountered in routine dental practice. In the present report, management of a fractured maxillary full‐arch cement‐retained (CR) fixed dental prosthesis supported by six implants is presented. Due to stripped screws, complications were encountered that prevented the retrieval of two of the six abutment screws, which was managed by using a hybrid retention approach, whereby a single full‐arch CR and screw‐retained (SR) ISP was used. The techniques used to successfully retrieve four of the abutment screws are described. The final retention design involved a combination of three CR and three SR restorations, which offers the advantages of both retention designs.
