Implants were loaded with an early loading protocol after 3\u2009weeks. Programmed recall visits were scheduled at the 6\u2010, 12\u2010, 36\u2010, and 48\u2010month follow\u2010ups and nonprogrammed visits in case of prosthodontic complaints. The type of maintenance was registered, and the final treatment outcome was classified as successful, surviving, unknown, dead, repair, or retreatment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Forty\u2010seven participants, mean age 65.4\u2009\u00b1\u20098.6, 74.5% female, were included (1\u2010IOD\u00a0=\u00a023; 2\u2010IOD\u00a0=\u00a024) and 44 completed the 4\u2010year follow\u2010up. A total of 159 prosthodontic maintenance events occurred and 89 in unscheduled visits. The most common event was the need for minor modifications of the denture base due to sore spots in the oral mucosa (<jats:italic>n<\/jats:italic>\u00a0=\u00a056 in 31 patients), matrix activation (<jats:italic>n<\/jats:italic>\u00a0=\u00a054 in 34 patients), and overdenture fracture (<jats:italic>n<\/jats:italic>\u00a0=\u00a025 in 18 patients). A \u201csuccessful\u201d or \u201csurviving\u201d outcome could be attributed to 57.5% of cases, whereas 38.3% needed repair.
