The aim of this prospective case series study was to evaluate full\u2010ZrO<jats:sub>2<\/jats:sub> implant\u2010supported restorations with angulated screw channel abutments (ASCs) in the molar region of the maxilla and mandible and their effect on hard and soft peri\u2010implant tissues, and patient\u2010related outcome measures (PROMs), during a 5\u2010year follow\u2010up period.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and Methods<\/jats:title><jats:p>Patients with a single missing molar in the maxilla or mandible with sufficient bone volume and an implant site free of infection were included. Thirty consecutive patients received a parallel\u2010walled implant with conical connection. After 3\u2009months, a full contour screw\u2010retained ZrO<jats:sub>2<\/jats:sub> restoration with an ASC was fabricated and connected to the implant. Clinical and radiographic examinations were performed 1\u2009month, 12\u2009months, and 5\u2009years after placement of the restoration. Implant success probability was calculated using Kaplan\u2013Meier statistics, and confidence intervals were given over the results at 5\u2009years. Patient\u2010reported outcome measures (PROMs) were scored prior to treatment and at follow\u2010up intervals. The primary outcome measure was the success of the restoration.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All patients could be evaluated after 5\u2009years. Success probability at 5\u2009years was 73.0% (95% CI [57.0%; 89.0%]). Implant survival was 100% and restoration survival was 97%. The encountered technical complications were easily repairable (<jats:italic>n<\/jats:italic>\u2009=\u200912). From loading to the 5\u2010years follow\u2010up, the mean marginal bone loss was 0.30\u2009mm (SD 0.52\u2009mm). Mean scores for plaque, calculus, peri\u2010implant mucosa, bleeding, and pocket probing depth were low, depicting healthy peri\u2010implant conditions. PROMs had significantly improved, and the mean overall score was 9.1\u2009\u00b1\u20090.7 (scale 1\u201310).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Full\u2010ZrO<jats:sub>2<\/jats:sub> implant\u2010supported restorations with ASC abutments employed in this study, when applied in maxillary and mandibular posterior regions, show a 97% survival rate.
