The tests consisted of a phase of cyclic loading followed by a leakage test. The maximum loading force was increased, and the procedure was repeated, until either the implant-abutment connection failed, or a leakage was detected. Loading criteria were modified based on the ISO standard 14801:2016.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_bmt-2025-0141_abs_003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The conical implant abutment connections exhibited fracture prior to leakage at varying failure forces and loading cycles, whereas the platform abutment type showed leakage or fracture at a relatively low force.
