Macro-Lock

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.

With this newest radiopaque, translucent quartz fiber technology, I reach for the Macro-Lock whenever I have minimal useable tooth structure.

Perfectly round root canals don’t occur in nature. They can be instrumented to this cross-sectional morphology, but this invariably requires the sacrifice of healthy tooth structure to facilitate the placement of round posts. Preserving ovoid canal shapes is preferable, but leaves voids around round posts. The oval post, as has been developed by RTD, provides intimate contact with oval canals and maximizes our ability to reinforce roots and retain cores, while allowing restorative dentists to preserve healthy tooth structure.

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.

We have evaluated several generations of RTD fiber posts in the clinic over hundred of patients in very varying situations. They have exceeded our expectations !

I have used RTD fiber posts clinically for over 20 years, since the early carbon fiber composition, with satisfying clinical results. The current generation of Macro-Lock posts seems to combine RTD’s best work as to a conservative, tapered shape, maximum bulk and strength in the most critical areas, and adequate retention mechanisms inside and outside of the tooth. The radiopaque X-RO fiber and Illusion color-change technologies make these posts even more appealing.

I'm glad that somebody finally developed this post design, and it seems natural that RTD would be the one to do this. An oval-shaped post addresses a well-known clinical problem in restoring endodontically-treated teeth. I also like the idea that I can customize it simply and slightly, for an even better fit.

I like these oval/flared posts because they offer maximum thickness in the critical cervical area, where its strength is most important.

I have been researching and working with posts for more than 10 years, and have concluded that more post and less resin is a better restoration. Because of that, this is an excellent post to enhance the endo-restorative complex. Moreover, I love the design, which matches the filing system and natural anatomy.

Why try to fit a round post into an oval-shaped canal? I have used the round Macro-Lock X-RO fiber posts for years with great success. This new design, an oval-shaped post with a tapered, round apical end, is ideal for these wide, flared and ovoid canals. The new oval version works with the same drills, and they are compatible any adhesive bonding system or cement I use. Viva l’ RTD! (As published in AGD Impact, September)

I use and like the unique Oval Macro-lock Post. It is great for large, non-round canals where extra strength is desired.
