PURPOSE The aim of this case report is to present a minimally invasive and esthetic treatment approach for the replacement of missing teeth removable partial dentures (RPDs) retained by zirconia ceramic resin-bonded attachments (RBAs). MATERIALS AND METHODS The RBAs were digitally designed and milled using CAD/CAM technology from monolithic 3Y-TZP zirconia ceramic. The RBAs had an optimized attachment design approved for zirconia ceramic. The preparation was based on general preparation guidelines for RBAs and resin-bonded fixed dental prostheses (RBFDPs). After placement of rubber dam, the RBAs were bonded with a phosphate monomer containing luting resin. RESULTS The presented RBA-retained RPD has been successful over 30 months of clinical observation without any complications. The patient was quite satisfied with the minimally invasive treatment procedure. CONCLUSION Zirconia ceramic resin-bonded attachments fabricated with a special attachment design are an esthetic and minimally invasive treatment approach. However, clinical data on the long-term outcome of zirconia RBAs are still needed.
