In the first model, two Astra\u2010Tech EV implants and two Locator abutments were placed, followed by the placement of two corresponding housings in the opposite blocks where nylon attachments were fitted. The second model was mounted with two Medentika Microcone RI implants and two Novaloc abutments. PEEK attachments were then placed in the corresponding housings. Blue\u2010pink\u2010clear nylon and white\u2010yellow\u2010green PEEK attachments\u2019 (<jats:italic>n<\/jats:italic>\u00a0=\u00a08 for each group) maximum dislodgement forces were measured at baseline (T<jats:sub>0<\/jats:sub>). Second measurements were conducted after 1080 insertion and removal cycles (T<jats:sub>1<\/jats:sub>). Corega denture cleanser solution was prepared by adding one tablet to 200\u00a0mL of tap water. All attachments were soaked in the solution for three minutes and rinsed under running water. Each group of attachments was soaked for 1080\u00a0min in total, corresponding to 1 year of clinical use. The final measurements were conducted after storage in the solution. One specimen and abutment were randomly selected from each group and examined using a scanning electron microscope. The data were analyzed by repeated measures ANOVA and Bonferroni multiple comparison test (<jats:italic>p\u00a0<\/jats:italic>&lt;\u00a00.05). The percentage decrease in the dislodgement force of the attachments was also calculated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Insertion and removal cycles significantly affected the retention values (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001). Storage in the cleanser did not significantly affect the retention (<jats:italic>p<\/jats:italic>\u00a0&gt;\u00a00.05). The lowest retention value was observed in blue nylon attachments (501.50\u00a0\u00b1\u00a033.39\u00a0gf [gram force]) after insertion\u2010removal (T<jats:sub>1<\/jats:sub>), with a similar trend after immersion (476.13\u00a0\u00b1\u00a039.75\u00a0gf) (T<jats:sub>2<\/jats:sub>). The highest retention was observed similarly in clear nylon attachments (1660.38\u00a0\u00b1\u00a041.73\u00a0gf) after insertion\u2010removal after immersion (1636.50\u00a0\u00b1\u00a062.20\u00a0gf) (T<jats:sub>2<\/jats:sub>).
