More information
The Macro-Lock OVAL Post, the advanced fiber post designed for maximum retention, with any type of cementation or resin build-up, is also available with RTD-patented Illusion and X-RO fiber technology.
Each post size has a tapered (0.4) apical segment, and a profoundly flared coronal section.
In addition, the surface of the post is roughened with controlled specificity to a highly micro-mechanical surface for excellent bonding and long-term retention.
Available in four sizes, the intrinsic post colors match the drill markings and help the clinicians distinguish one size from another. With this Illusion Technology, the color disappears within seconds at body temperature, but the color can be reconstituted, if necessary for re-treatment, within seconds.
