<br/><br/> This study evaluated a new post-crown system as compared to another post system (flexi-post) regarding retention, microleakage, retrievability and finite element stress analysis. The results showed no significant difference between the two post systems tested regarding tensile force test. Howere when subgroups were compared only resin cement showed significant difference
