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 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.
