AIM:Evaluate the degree of retention between the 2 most commonly used intraradicular post systems. The methodological
design chosen to carry out this work,was a experimental in vitro comprison 40 root portions were used, which were used
(with the same instrument) in order to accommodate intraradicular posts. In the first 20 (coded), sectorized impressions were
taken, followed by the corresponding protocol for the preparation of postformed metallic poles (castings) by indirect method
(COPISMY Method), after being obtained, these poles were cemented under controlled pressure on (Groups A and B) The
second 20 parts were also cemented under controlled pressure, prefabricated non-metallic posts (Groups C and D) following
the same steps as for castings. Subsequently, all samples were included in transparent resin cubes in order to cross-cut them
for subsequent observation, measurement and image capture. Then all numerical values obtained were subjected to a strict
statistical study to try to determine if there are statistically significant differences between both groups. Depending on the
values obtained, statistically significant differences between groups A and B (34.52 and 38.58 um) could be established with
respect to C and D. (122.95 and 131.52 um)
