Oval Post Sizes

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.

Testimonials

Leendert (Len) Boksman, Ontario, Canada

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.

Brian Gray, General Dentistry Washington DC, USA

This is truly one of the best ideas I've seen in dentistry in a long while. These new posts address a real clinical indication from the structural, geometric, functional and esthetic perspectives all at once. High strength, macro-retention, and excellent radiopacity combine in this unique shape to replace cement with high-performance fiber-reinforced composite. During our pre-market evaluation the posts were so successful that I made the rare decision to implement immediate use in our clinical regimen - they are incredible.
