Macro-Lock

For the most commonly shaped canal; an ovoid post! What a concept! Without changing armamentarium for preparing the canal, RTD now has a post that evolves into an ovoid shape coronally to more adequately fit the natural anatomic shape of the canal. Less tooth destruction to adapt the tooth to the post and less resultant cement, creates a stronger tooth and more resistance to dislodgement and fracture. When room allows the addition of Fibercones adds anti-rotational stability as well as further composite reduction. This is currently the state of the art in fiber post technology and tooth restoration.

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.

I have used these posts clinically with satisfaction, and appreciate their properties and their quality.

The validity of fiber post has been confirmed by both of the clinical data and experimental studies. I have been using Macro-Lock fiber post for more than three years. The clinic outcome is excellent. Meanwhile, the mechanical properties of Macro-Lock fiber post have been tested in our studies, experimental or numerical analysis. The quality of Macro-Lock fiber post is outstanding.
