Macro-Lock

I have used RTD fiber posts since their first generation in the 1990s. Their current composition and quality are unsurpassed so, as a leader, it makes sense that they would broaden their family of shapes and designs. We have been using the Macro-Lock Oval Posts for nearly a year, and find them to be a valuable addition to our armamentarium. Though we still also place accessory posts, these new oval posts are a simpler way to minimize cement thickness and add strength in many over-flared or oval canals and post spaces

I was introduced to RTD quartz fiber post years ago; first the DT Light-Post, then the Macro-Lock design. This latest evolution of the Macro-Lock is a unique but simple approach to a common clinical challenge; those unusually-shaped canal that occur naturally in most teeth, and which present after a root canal re-treatment or a post-removal.

I have used RTD fiber posts regularly for more than 10 years and I have had the opportunity to observe the constant improvement with each generation of fiber post. The replacement of the carbon fibers with quartz fibers has dramatically improved the bio mechanical properties, with a modulus of elasticity closer to the dentin, the adhesion with all of the bonding systems as well as the optical properties of the post, to optimize the aesthetics of the final restoration.

High radiopacity for a clear and precise diagnosis: X-RO technology is always visible on X-rays, even if it is invisible in the mouth. Thus, covering all clinical needs. In my clinical practice, it is common to treat teeth that require endodontic therapy or have been previously treated; in many of these cases, the coronal structure is severely compromised or even absent. In such circumstances, the use of these materials becomes indispensable for proper tooth reconstruction, enabling restorations that are functionally, esthetically, and biomechanically stable over time.
