Participants were randomly allocated to either a bar\u2010locator group (\n                      <jats:italic>n<\/jats:italic>\n                      = 8) or a bar\u2010clip group (\n                      <jats:italic>n<\/jats:italic>\n                      = 8). Prosthetic complications, including retentive component wear, screw loosening, tooth wear, denture fracture, relining, and other maintenance events, were clinically recorded over a 5\u2010year follow\u2010up period.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All participants completed the 5\u2010year follow\u2010up (100% retention). A total of 24 prosthetic complications were recorded in the bar\u2010locator group and 13 in the bar\u2010clip group. The mean number of complications per patient was 3.0 \u00b1 1.3 for bar\u2010locator and 1.6 \u00b1 0.9 for bar\u2010clip overdentures (absolute risk difference = +1.4; 95% CI: \u22120.3 to 3.0). Although the bar\u2010locator group demonstrated numerically higher frequencies of retentive insert wear, tooth wear, and minor fractures, none of the between\u2010group differences reached statistical significance (\n                      <jats:italic>p<\/jats:italic>\n                      &gt; 0.05).

The bar\u2010locator system was associated with a higher overall maintenance burden. In contrast, bar\u2010clip overdentures required relining more frequently, reflecting distinct long\u2010term maintenance profiles rather than differences in durability. These pilot findings support the feasibility of a larger randomized trial and highlight the need for future studies incorporating patient\u2010reported outcomes, cost\u2010effectiveness analyses, and time\u2010to\u2010event assessments of prosthetic maintenance.<\/jats:p>\n
