Titanium and titanium alloy are the predominant materials for dental implants. However, in long-term applications, they are associated with issues such as the release of titanium particles, potential induction of immune responses, and aesthetic drawbacks. Zirconia implants, by contrast, present a promising alternative due to their tooth-like color, excellent mechanical properties, and high biocompatibility, and have gradually been applied in clinical practice. Currently, most zirconia implants adopt a one-piece design. With the advancements in processing and material science, newly developed two-piece zirconia implants offer greater restorative flexibility and a broader range of indications compared to one-piece zirconia implants. This paper reviews relevant domestic and international literature and summarizes the current research on the mechanical properties, biological properties, and clinical outcomes of two-piece zirconia implants, aiming to provide a reference for clinicians.
