This case report presented a minimally invasive and esthetic treatment approach for replacing missing teeth with removable partial dentures retained by zirconia ceramic resin-bonded attachments. The resin-bonded attachments were digitally designed and milled using CAD/CAM technology. The clinical observation over 30 months showed a successful outcome without complications.
Objective: The aim of this case report was to present a mini-mally invasive and esthetic treatment approach for the re-placement of missing teeth removable partial dentures re-tained by zirconia ceramic resin-bonded attachments. Method and materials: The resin-bonded attachments were digitally designed and milled using CAD/CAM technology from mono-lithic 3Y-TZP zirconia ceramic. The resin-bonded attachments had an optimized attachment design approved for zirconia ce-ramic. The preparation was based on general preparation guidelines for resin-bonded attachments and resin-bonded fixed dental prostheses (RBFDPs). After placement of rubber dam, the resin-bonded attachments were bonded with a phos-phate monomer-containing luting resin. Results: The pre-sented resin-bonded attachment-retained removable partial denture was successful over 30 months of clinical observation without any complications. The patient was 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 resin-bonded attachments are still needed. (Quintessence Int 2023;54: 220???226; doi: 10.3290/j.qi.b3819523)
