MBL remained stable after the initial remodeling phase, with no clinically relevant differences between materials. Peri\u2010implant soft\u2010tissue conditions (BOP, plaque presence, PD, KT) were similar for Zr and Ti. Two zirconia implants were lost during the observation period. Peri\u2010implantitis was diagnosed in 7.9% of the implants, affecting three titanium and three zirconia implants. Technical complications differed between groups: chipping occurred significantly more often at Zr implant\u2010supported crowns. Ti implants showed two screw\u2010loosening events, while Zr implants showed two cases of decementation. Esthetic and patient\u2010reported outcomes were comparable, with low perceived mucosal color differences and a slight preference for Zr sites, if detectable.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Zr and Ti implants showed similar peri\u2010implant health, marginal bone stability, esthetic outcomes, and patient satisfaction after 3\u2009years.
