Ready made post design plays an important role with resin cement ability on
post retention in to the root canal. While the paraposts are the most retentive.
To compare the resistance of serrated Para post, tapered-smooth, and threaded para posts, c
emented with
panivia21 to transverse load.
Most of previous studies used tensile or pressure forces (as parallel to tooth
long axis) to study the cemented posts resistance, But there are lateral forces tried to loosen, or bending
those posts.
Aim of study: detecting the resistance of Ready
- made Serrated- para Posts cemented by three different
Luting Cements to BendingMoment by applying a horizontal force on the free post end.
