Replacement of a single-tooth implant restoration with the abutment dual-scanning technique: a case report

Abstract

Abstract Background Digital technologies have not only revolutionized workflow strategies for implant- supported fixed prostheses but also changed preferences in the choice of restoration retention. Owing to the effortlessness of developing workflows with digitalization, screw-retention has become favored for initial prostheses. However, cement retention is still indicated for cases in which abutment reuse is needed for replacing failing restorations with technical complications. Case presentation In this case report, a modified digital workflow is described for treating an impaired occlusal relationship. A dual-scan approach for an abutment-level digital implant impression to remake a cement retained implant supported fixed restoration is defined in detail. Conclusion Clinicians can highly benefit from the presented strategy, which offers an efficient digital workflow to simplify cement-retained abutment level impressions through the use of an intraoral scanner. Exchanging intra- and extra-orally surface scanned abutment data may become an option in complete digital model-free workflows for addressing problems related to cement-retained implant supported fixed prostheses.
