ParaPost XH’s undercut, slotted head is designed to lock on composite and glass ion-omer cores firmly and easily. There are no sharp edges that could cause stress and lead to core fracture. The diamond pattern provides max-imum retention, and the broad, flat shoulder stop ensures proper seating. They are available in 7 sizes, minimizing the amount of dentin that needs to be removed. The ParaPost XH is used with standard ParaPost drills. For more information, call (800) 221-3046.
