C-I™ Post System:
Choose from three popular styles.
C-I™ White Posts
Parkell’s White C-I Posts feature greatly improved radiopacity for better viewing on a dental x-ray. These glass fiber/epoxy resin posts use the same calibrated drills as all the posts in the C-I system. However, the reinforcing fibers in the white C-I post are braided like a glass splinting ribbon to improve strength and stiffness. A cervical bulge reinforces the post and resists marginal opening due to flexing (a common weakness of resilient posts).
Available in both fine and medium sizes, the C-I White Posts are slightly tapered to the precise 2.6° taper of our metal posts to permit safe placement with a reduced danger of root perforation. The taper also permits maximum post length in narrow roots, along with smooth venting of excess cement.
C-I™ Plastic Pattern Posts (direct or indirect)
The C-I Plastic Pattern posts are ideal for cast posts and cores using either the direct or indirect technique. Simply half-fill the lubricated post hole with self-cure resin or wax, then seat the C-I plastic burnout post. Fill a core pattern with wax or acrylic and slip the pattern over the post to create a fast, ready-to-sprue post/core assembly. After you’ve removed the pattern, use the stainless steel temporary post to retain the interim restoration. Simply cement the post, fill a plastic crown with tooth-colored acrylic and seat it over the post’s head for coverage until the casting comes back from the laboratory.
C-I™ Stainless Steel Posts (direct)
The C-I Stainless Steel post gives you a proven chairside system for amalgam or composite cores. The embossed head provides undercuts to grip the core material. If necessary, you can also reduce the head with a diamond or carbide before cementation. Serrations along the shank assure strong retention in the cement. After cementing the C-I post in the canal, just fill the pattern with composite and seat it over the post’s head for an instant anatomical core.
