At this point, narrow dental implants may provide an effective option to avoid complex surgical treatments. The aim of this trial was to evaluate long\u2010term survival, prosthetic and biological complications, and OHRQoL for two\u2010piece narrow dental implants supporting overdentures with Locator\u2010attachments.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Twenty\u2010five patients with edentulous mandibles received four narrow dental implants and retained dentures with Locator attachments. Following successful implantation, immediate loading of anterior implants with Locator attachments was performed, while posterior implants underwent a conventional healing procedure. Follow\u2010up examinations included documentation of implant and denture\u2010related complications, modified gingiva index, modified plaque index, OHIP\u2010G, and radiographic measurements of bone loss.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Up to 9\u2009years after restoration, 18 patients with 72 implants were available for the follow\u2010up. During the observation period, one implant was lost in the immediate loading group. Implant survival was 98% and 100%. The outcomes of mPI and mGI for the 18 patients hardly differed between the groups. During the observation period, 136 prosthetic complications occurred. Scores for the different OHIP\u2010G domains at the last follow\u2010ups were stable over the years.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Throughout an extended period of observation, we found stable implant survival rates, good maintenance of oral hygiene, and manageable prosthetic complications. The OHRQoL was satisfying over the years, suggesting that this treatment option could be favorable for older individuals.<\/jats:p><\/jats:sec><jats:sec><jats:title>Trial
