More information

The post has a tapered apical segment, and a parallel 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 six 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.

Manfred Friedman, Private Practice, Adjunct Professor, Schulich School of Medicine & Dentistry, Univ. of Western Ontario, London, Ontario, Canada

I have placed over 500 Macro-Lock posts without a single failure. The tapered shape facilitates minimal removal of tooth structure and ensures a minimal amount cement, which minimizes polymerization shrinkage and micro-leakage. Superior physical properties, along with macro and micro-retention, and anti-rotational features make this my post of choice for extensively broken down teeth.

I have used RTD fiber posts since 1997 and do not have cases of breaking or failure in my treatments.
