The new Cytco-K Titanium Post System combines the best of both parallel and tapered systems. For stability and retention, this titanium-alloy post begins with a parallel design, which incorporates tapered ends to eliminate stress in the apical portion. Each post has self-tapping threads at the top that secure themselves only in the cervical area of the root where the walls are thickest. Two vent grooves run the length of the post to allow excess cement and dentinal debris to escape. For more in-formation, call (800) 924-7393.
