Sizes 3, 4, 4.5, 5, 5.5, 6 ParaPost XT are threaded, parallel-sided posts with rounded, undercut heads for direct post/core buildups in one appointment. Ideal for glass ionomer and composite core buildups, which require extra retention and extra safety.
Rounded edges of the head minimize stress points that could lead to core failure
Undercut, slotted head securely locks on glass ionomer and composite core materials firmly and easily
Low profile threads cut a clear path through the dentin, minimizing insertional stress
Raised diamond-shape retention pattern in the apical section provides additional retention and greater resistance against rotation
Parallel sides distribute functional stress equally along the entire length of the post
