Clinical Outcomes of Single-Piece Zirconia Implants Compared With Tooth-Supported Fixed Dental Prostheses: A Retrospective Study

Single-piece zirconia implants, despite requiring a longer treatment duration and more appointments, offered superior mid-term complication-free survival compared with conventional three-unit FDPs for replacing a single mandibular posterior tooth. When the preservation of sound adjacent teeth is prioritized, single-piece zirconia implants represent a biologically favorable option for suitable patients.
