Flexi-Post and Flexi-Flange

Through the incorporation of the patented split shank, the stresses of insertion are absorbed by the post (not the root) during placement.
  Flexi-Post® predictably provides maximum retention with minimal stress!
 The Benefits of the Patented Flexi-Post:
  Cuts into dentin rather than pushing it away.
 The split-shank closes upon insertion to deliver maximum retention with minimal stress.
 Removes all dentinal debris, enhancing ease of placement.
 The Flexi-Flange® offers the same patented split-shank. However, it incorporates a wider flange to sit into the coronal tooth structure. This post is recommended in cases of little or no coronal dentin.
