Aesthetic, light-transmitting post used to retain core buildup when there is insufficient tooth structure. Offers excellent radiopacity for easy and immediate identification on an X-ray, high flexural strength, and ideal modulus elasticity. Will not interfere with natural light transmission, resulting in outstanding aesthetics. Allows for fewer root fractures than metal posts. Parallel design includes a retentive head, which provides maximal retention of core buildup; tapered design includes retention on the head and allows for a more conservative preparation; and serrated design offers retention along the entire length of the post. Posts are
color coded for easy identification.
