Implant probing pocket depth (PPD) · Adults (18 years or older) with one missing tooth in the aesthetic zone needing an implant-supported single crown
Metal-free implant abutments (zirconia) showed no clear difference in implant probing pocket depth (PPD) compared with metal implant abutments (titanium); GRADE not reported.
