This in vitro study aimed to evaluate the primary stability of dental implants of varying lengths across simulated bone densities using the insertion torque value (ITV) and resonance frequency analysis (RFA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>Morse\u2010taper implants (5.0\u2009mm diameter) were divided into four groups based on length: 5, 6, 7, and 8\u2009mm. Implants were placed into polyurethane foam blocks of varying densities: PCF 40, PCF 30 (with 2 and 1\u2009mm cortical layers), and PCF 20 (with a 1\u2009mm cortical layer). Primary stability was measured via ITV and RFA, yielding an implant stability quotient (ISQ).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In high\u2010density foam (PCF 40), both ITV and ISQ increased proportionally with implant length, with the 8\u2009mm implant demonstrating the highest stability (ITV\u2009=\u2009109.26\u2009\u00b1\u20094.79\u2009Ncm and ISQ\u2009=\u200973.5\u2009\u00b1\u20092.32). Conversely, in low\u2010density foam (PCF 20\/1\u2009mm), a direct relationship was observed, where the shortest implant (5\u2009mm) exhibited the lowest stability (ITV\u2009=\u200936.8\u2009\u00b1\u20093.27\u2009Ncm and ISQ\u2009=\u200945.8\u2009\u00b1\u20092.66), whereas the highest stability was presented by the 8\u2009mm implant (ITV\u2009=\u200961.36\u2009\u00b1\u20092.00\u2009Ncm and ISQ\u2009=\u200956.3\u2009\u00b1\u20092.67).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Implant length significantly influences primary stability, but its effect is highly dependent on bone density.
