A total of 80 hollow samples were divided into two groups and filled either with a prefabricated <jats:styled-content style=\"fixed-case\">FRC<\/jats:styled-content> post or with individually adapted <jats:styled-content style=\"fixed-case\">FRC<\/jats:styled-content> posts. For each group, half of the samples were subjected to thermocycling (5\u201355\u00a0\u00b0C, 5000\u00d7). The remaining samples were kept for 24\u00a0h at 37\u00a0\u00b0C at 100% relative humidity. All samples were loaded diametrically until fracture. The null hypothesis tested was that the fracture resistance of standardized bone samples is not influenced by the type of <jats:styled-content style=\"fixed-case\">FRC<\/jats:styled-content> post, independently of the exposure to thermocycling. Results were evaluated by <jats:sc>anova<\/jats:sc>, and subsequent multiple comparisons were performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The samples filled with the individually adapted <jats:styled-content style=\"fixed-case\">FRC<\/jats:styled-content> posts were more resistant to fracture than the prefabricated ones (<jats:italic>P\u00a0<\/jats:italic>&lt;<jats:italic>\u00a0<\/jats:italic>0.001), but this difference was not apparent in the thermocycled groups. Detachment of the posts upon fracture was highest after thermocycling for both groups, amounting to 55% and 95% for the individual adapted posts and the prefabricated posts, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Initially, the samples filled with the individually adapted <jats:styled-content style=\"fixed-case\">FRC<\/jats:styled-content> posts were more resistant to fracture than those filled with the prefabricated ones.
